饮用水与健康（Drinkingwaterandhealth）
饮用水与健康（Drinking water and health）The concept of a conflict, drinking waterUndoubtedly, with the increasingly severe environmental pollution, water has become an important factor threatening people's health. According to the WHO statistics, 80% people drinking water and the incidence of unclean. In recent years, the market of various brands of mineral water, pure water and water purifiers increasing, drinking water what is beneficial for the body, it is very concerned about the event.On the one hand, people on the quality of tap water sceptical, even afraid of production process make the water tap water mixed with some toxic gases, that pure water and mineral water is more beneficial to health. On the one hand, experts believe that the current market on pure water and mineral water is not necessary for high consumption products, even pure water is harmful to the human body, urged the public to drink their own water.So, in the end we should have what kind of drinking water? Mineral water is necessary in daily life? The water is not pure enough? Tap water is really harmful to human body?Two, pure water and mineral water and human healthThe biggest difference between mineral water and pure water, the water is different. The real mineral water taken from deep underground confined water, the water needed for the human body contains minerals and trace elements. The purified water is to use city tap water or water from wells, through the reverse osmosis membrane purification treatment, so that the waterbecomes very pure, does not contain any bacteria and other substances other than water.What mineral water is good, without any other material or water?I group according to the collected data found in the following conflict perspective.Experts advocate drinking mineral water that a person drink every day more than 2 kg of water, water is the best solvent, rich in mineral water by various wholesome ingredients should make full use of. Although the purified water to remove all harmful substances, but also removes water useful things. Especially the pure water solution with strong ability, in a large number of people drinking water, nutrients and trace elements in the human body will quickly dissolve in the water, and then excreted through the kidneys in vain, so, don't drink too much pure water. Especially often drink pure water, the greater the impact on children. At present, many city has issued a notice prohibiting the students drink pure water, to ensure that the trace elements and nutrients in these growing children are not being lost.Experts advocate drinking pure water is that water is mainly thirst, and pure water is the best drink. Pure water has a very strong dissolution and penetration ability, in the supplementary water at the same time, to remove the body of toxins and impurities can make some excretion of harmful substances stored in the body.They believe that the nutrients and trace elements needed by the body does not have to depend on the water can get from food.The content of trace elements in food is much higher than that of water, such as a cup of orange juice in the mineral content of more than 400 cups of mineral water; 1 grams of black fungus is equal to 10 cups of mineral water containing iron value. The trace elements in mineral water is not worth mentioning, harmful substances dissolved in water can make people sick.Two party experts say is reasonable, however, with the background of serious environmental pollution has many deep groundwater dissolved into the harmful substances, such as bad water, mineral water "congenitally deficient", it is difficult to achieve the standard of drinking. Then we learned about "hard knowledge, we know that the water contains minerals is not the more the better. Long term drinking water hardness is too high or too low is not conducive to human health. Although the purified water is very pure, but many nutritionists believe that pure water once unsealed or seals in contact with the air within 24 hours will be breeding bacteria. Moreover, excessive drinking water will lead to the loss of trace elements in the human body needs, not to mention the current quality on the market most of the drinking water problems.Three, tap water really harmful to human health?Now people talk about drinking tap water will haunt, mainly because of fear of not removing impurities and microorganisms as water tap water production process, and afraid of the water purification process with some toxic gases. Based on this,My group members first begin to understand the production process of tap water.1, tap water is how to produce?As everyone knows, because of natural and human factors, contains a variety of impurities in raw water. From the angle of water treatment, these impurities can be divided into colloidal suspensions, and dissolved in three categories. City water plant water treatment is to remove the raw water to human health and industrial production of suspended matter and harm of colloids, bacteria and other harmful ingredients, so that the quality of the purified water can meet the need of drinking water and industrial production. City Tap Water Corporation water by conventional water treatment process, it includes mixing, reaction, sedimentation, filtration and disinfection processes.(1) the coagulation reaction processRaw water of the water pump after the upgrade, the first after the coagulation process, i.e.:The raw water + water treatment agent, mixing, reaction, water.Since the agent evenly mixed with water until the large particle floc formation, general coagulation process. The commonly used water treatment agent with poly aluminum chloride, aluminum sulfate, ferric chloride. Shantou city is the use of basic aluminium chloride. According to the chemical properties of aluminum, aluminum ion in water into chemical ionization of water molecules, and it has the following reversible reaction:Al3+ + 3H2O vs. Al (OH) 3 + 3H+Aluminum hydroxide has adsorption effect, the water is not easy to precipitate particles and small suspension destabilization and mutual coalescence by bridging to form larger flocs, separated from the water, in order to settle down.The mixing process requirements quickly after adding the medicine. Mixed purpose is through intense mixing, hydraulic machinery, so that agents rapidly and uniformly dispersed in water.The coagulation treated water through the pipe into the sedimentation tank, clean water into second stages.(2) precipitation treatmentMixed floccule coagulation stage formed by means of gravity separated from the water by a process known as precipitation, this process in the sedimentation tank. Water flows into the settling zone, distribution of the area of the cross section into the settling zone, and then slowly to the outlet area. The water particles sink to the bottom of the pool, sludge piled up and concentrated, regularly drained away.(3) filteringFiltering generally refers to the granular quartz sand filter layer in the gap by suspended particles through adhesion, thus further removal of fine suspended impurities, organic matter, bacteria, virus, so that the water clarification process.(4) after filtration disinfectionAfter being filtered, turbidity is further reduced, and the residual bacteria and virus without turbidity protection or attachment, to create favorable conditions for the filter after disinfection. Disinfection is not to eliminate all microbes, only kill pathogenic microorganisms. Although water coagulation, sedimentation and filtration, can remove most bacteria and viruses, but the disinfection of drinking water to ensure the bacteriological indicators, at the same time it makes the city water terminals maintain a certain amount of residual chlorine to control bacteria and indicate pollution. The quantity of chlorine disinfection (chlorine) in1.0-2.5g/m3. Mainly hypochlorous acid generated by the reaction of chlorine and water oxidation in bacteria, bacteria and enzyme system to destroy bacteria to kill. After disinfection of water from the water tank by pumping station upgrade reaches a certain pressure, through water transport and distribution network to thousands of households.2, tap water does not contain substances harmful to human health?The production process of tap water over the river is visible, the original variety of suspended particles and colloidal substances have been isolated in the coagulation process. Is the eradication of pathogenic microorganisms in the water also has disinfection in the filter postprocessing process. Therefore, in tap water in the production process have been harmful to human health material containing raw water isremoved.So, join in the production process of medicine? In the process of removal of impurities in the original one by adding a new impurity. Whether these new impurities can be harmful to our health?Water treatment agent is added in the process of coagulation, the general situation and the suspended granule and colloidal precipitation with open, so as not to affect the water quality of the factory. Then, only the chlorine.Chlorine disinfection is the last step in the production of tap water. To assist the water with chlorine after reaction can take water to the public family. So, whether we can be harmful to chlorine?We focus on chlorine.Chlorine (CL2) is a kind of pungent yellow green gas, soluble in water, at room temperature for 1 Volume 2 volume water dissolved chlorine. Under the same conditions, chlorine than the same volume of air, under standard conditions, the density of 3.214g/L. Chlorine is easy liquefaction, when the pressure is 101. 3kPa, cooling to -34. 6 C, the gaseous chlorine becomes yellow oily liquid chlorine. Liquid chlorine to cooled to -101 DEG C, becomes solid chloride. Chlorine is a toxic substance has strong stimulation to the human body, a small amount of chlorine inhalation will stimulate the mucous membrane of nasal cavity and throat, and chest pain and cough caused by inhalation of more chlorine suffocation.When chlorine is added to water, the reaction will happen:CL2 + H2O = HCL + HCLOBecause the chlorine disinfection process in a small amount (usually in 1L water only about 0.005g, the chlorine) can be said that as long as the factory tap water to meet the normal standards, the investment of chlorine in tap water will react with water to produce other substances, so that the factory water does not contain CL2 above the so-called "city. To maintain a certain amount of residual chlorine water terminals", actually refers to chlorine, instead of chlorine.However, although the chlorine has been completely reaction, but other substances generated. We first look at the hypochlorous acid. Hypochlorous acid (HCLO) has strong oxidation, so it has strong sterilization ability, is a commonly used disinfectant. Hypochlorous acid is a weak acid is very unstable, prone to the following reaction under the condition of light:2HCLO = 2HCL + O2 =So, the water may contain impurities only HCl.Hydrogen chloride (HCL) is a colorless pungent gas, its density than air, is about 1.26 times the air. Hydrogen chloride is easily soluble in water (about 1 volume of water to hydrogen chloride dissolved 500 volume 0 degrees centigrade). An aqueous solution of hydrogen chloride is known as hydrochloric acid,hydrochloric acid, is a strong oxidising and strong corrosion.From the above equation, according to the conservation of chlorine, hydrogen chloride, chlorine and water react a certain amount of substance after the final amount of substance is two times greater than that of chlorine. Due to the use of water in the production process of chlorine in the amount of hydrogen chloride produced by nature very little. According to the common sense of health, we know that the human body contains a small amount of hydrochloric acid in gastric juice, it can be considered that hydrogen chloride trace does not affect human health, almost negligible. In addition, hydrogen chloride is volatile gases, these properties can be inferred based on the boiled water does not contain hydrogen chloride.Thus, we can conclude that the national standard production process meets the tap water is not harmful to human health.Finally, the problem we have drinking water on human health effects of social survey. Through the survey, we found that 14.3% of the people drinking pure water, 49% people drinking tap water, 36.7% of the people in drinking water. In the drinking water of people: about 36.7% of people think that pure water is harmless to the human body, a love of drinking; 22.4% of people think that drinking water is harmful to the human body, does not love drinking; in addition, there are about 40.9% people for potable water is harmful not too clear, because most people are drinking, also after drinking. Most people do not drink tap water because of the serious situation of water pollution, said that if the natural economic conditions allow, willing to drink natural mineral water or river water. Mostpeople choose to drink pure water which mostly from the comprehensive consideration of quality and price etc..summaryLong term drinking mineral water, the body of some trace elements may take excessive photography. According to the relevant data, a 68 kg body weight, other trace elements contain 5.68 grams of iron, 2 grams, 0.11 grams of zinc copper and a certain amount of content is ppm (PPM), or ppb (1/1000000000), and even fewer.Effect of trace elements in the human body is very subtle, lack of risk, excessive harmful, it is essential, but it is not The more, the better. Some of the contents of trace elements in mineral water more than natural water, long-term drinking can cause some trace elements more than needed by the body, as for pure water, mineral water and water on the contrary, the lack of minerals and trace elements, to the other extreme.One side of the water. Scientific research tells us that mankind in the long evolution and natural water indissoluble bound with the natural water, dissolved minerals and trace elements, the content and meet the normal requirements of the human body, the trace elements in the human body in addition to food, mainly rely on water supplement. Therefore, the position of natural water in human health is irreplaceable. We need to do is to improve the quality of natural water, to protect the natural water sources in rural areas, from the city's tap water pollution, should meet the national hygiene standards. In addition, the water must be boiled before drinking, drinkboiling water to keep healthy. Chlorine dissolved in water will generate hypochlorous acid and other substances, hypochlorous acid has strong sterilization bleaching effect, but at the same time, the water will produce some hypochlorite and organic chlorine (product of some organic compounds in combination with chlorine they are called chlorine). Chlorine has strong oxidation, so in terms of the human body, it belongs to the mutagenic substances, if often drink tap water containing chlorine, obviously, is extremely detrimental to health. However, residual chlorine in tap water is unstable substances, it is easy to decompose and volatilize in light or heat effect. So, the tap water after boiling, the chlorine can do except.The boiled water is unfit for drinking, why? This is because the water usually contains trace amounts of nitrate and heavy metal ions, such as lead, cadmium, when heating water for a long time, because the water is evaporating, concentration of nitrate and heavy metal ions is relatively increased. Nitrate containing more water in the stomach into the body after nitrate which will be further reduced to nitrite. The nitrite will damage the blood oxygen transport function, the tachycardia, dyspnea. When the situation is serious, and deadly danger. The same heavy metal ions on the human body is harmful.Can not drink unboiled water, and repeatedly should not drink boiling water, not drink pure water or distilled water, most health? In fact, the general water containing calcium and magnesium and other elements, are the essential elements of human body, the body weight of calcium accounted for about 1.38%, is the main component of bones and teeth, and to maintain the myocardial contraction and promote normal blood coagulationplays an important role. About 0.04% of the body weight of magnesium, 70% of them exist in the bone, per person per day is about 0.3 - 0.5 grams of magnesium. A part of these two elements is from drinking water intake. Therefore, only drink distilled water or pure water is also not very good.So, how to drink boiling water is appropriate? Boil water, when the water in the kettle began to boil, the pot that water temperature has reached 100 degrees, most of the bacteria were killed. If the smell of chlorine in tap water is heavy, it may be appropriate to cook for one or two minutes, so whether it is tea or boiling water, cooking is very suitable.Preliminary opinions and suggestionsNatural is the best, solve the fundamental measures of drinking water health problem is to protect the environment and control of water pollution. Increase publicity and education efforts to raise public awareness of water resources, prevent pollution, strengthen the construction of city sewage treatment and related facilities to further improve the relevant laws and regulations of city water resources and environmental protection, increase environmental protection efforts, improve the quality of water resources.The relevant departments should strengthen supervision and management of the water market, so that people drink really "pure" water.。

饮水水源水质管理参数选择探讨 (1)
饮水水源水质管理参数选择探讨胡跃恒 吴珊 李冬（北京工业大学建工学院，北京 100124）摘 要 随着水环境恶化的日益加重，作为饮用水水源的地表水中，一些物质会随着时间的推移不断积累，当达到一定浓度将会对饮用水的安全构成威胁。
为了对这些潜在水质不安全因素进行预警，可选择相应的水质控制指标，即水质因子，并在历史数据的基础上通过建立水质模型模拟水源的水质变化趋势，并提出相应的应对措施，有利于饮水水源水质的安全保证。
关键词水源 饮用水 水质参数 预警Abstract: With the increasing aggravation of the deterioration of the environment, harmful substances in surface water source accumulate as time goes on, when they reach a certain concentration will pose a threat on the safety of drinking water.
