Environmental

• Contaminants are: (1) the discharge of untreated industrial waste water; (2) the discharge of untreated sewage; (3) extensive use of fertilizers, pesticides, herbicides, agricultural land caused by sewage; (4) stacking industrial waste in the river and garbage; (5), deforestation, soil erosion; (6) due to over-exploitation, resulting in mine effluent（污染物主要有：
机、轮船是当代的主要运输工具，它们烧煤或石油产生的废气也是重要的污
染物。
• 3.Forest fire smoke.森林火灾产生的烟雾。 • 4. Life stoves and heating boilers生活炉灶与采暖
锅炉
Air pollution control空气污染的防治
• 1. To reduce emissions减少污染物排放量 • 2.control atmospheric emissions and take advantage of self-purification capacity控制排放
市污水和工业废水的治理力度
• 3. Enhance the environmental awareness of citizens加强公民的环保意识 • 4. Water resource utilization to achieve实现废
水资源化利用
3.Noise pollution
• Due to natural processes or human activities have caused all kinds of unwanted sounds, more than a human could allow an extent that the phenomenon of human and animal health hazards.（因自然过程或人为活动引起各种 不需要的声音，超过了人类所能允许的程 度，以致危害人畜健康的现象。）
Prevention and control noise pollution
防治噪声污染
• 1.The noise sources need a quiet place away from使噪声源远离需要安静的地方 • 2.Control the direction of propagation of noise控制
Environmental pollution
1.Air pollution 2. Water pollution 3.Noise pollution 4.Solid waste pollution
1. Air pollution
• Generally refers to low-level near the ground or air pollution, and sometimes refers only to indoor air pollution（一般指 近地面或低层的大气污染, 有时仅指室内空 气的污染 ）
用薄膜、包装用塑料膜、塑料袋和一次性塑料餐具（以下统称为塑料 包装物）在使用后被抛弃在环境中，给景观和生态环境带来很大破坏)
• 2. Pollution of used batteries废旧电池污染
Measures and recommendations
• 1.Currently, to prevent the “white pollution” should mainly strengthen the recycling of used plastic film from start to step up research while pollution-free, easy to recycle plastic film 当前，防止
“白色污染“主要还应从加强回收废旧地膜开始，同时加紧研究无公害、易回收地膜。
• In order to protect the environment, consider using the environmental mercury and cadmium batteries, while the protector of the environment to actively do to publicize the dangers of used batteries, battery recycling advocates together to protect their homes为了保护环境，可以考虑使用不含汞和镉的环保电
和充分利用大气自净能力
• 3.Rational planning of industrial areas and non-industrial zone合理规划工业区与非工业区 • 4.Afforestation绿化造林 • 5. Measurement of pollutants污染物的测量
2. Water pollution
Major air pollution sources
• 1.Industrial production is an important source of air pollution • 2. Transportation: cars, trains, planes, ships of the principal means of transport, they are burning coal or oil emissions from pollutants is also important.交通运输：汽车、火车、飞
（1）未经处理而排放的工业废水；（2）未经处 理而排放的生活污水；（3）大量使用化肥、农药、 除草剂而造成的农田污水；（4）堆放在河边的工 业废弃物和生活垃圾；（5）森林砍伐，水土流失； （6）因过度开采，产生矿山污水。）
Measures and recommendations
措施与建议
• 1. Strengthen the protection of drinking water source water intake 强化对饮用水源取水口的保护： • 2. Increase the urban sewage and industrial wastewater treatment efforts 加大城
山丘），以及利用其他隔声材料和隔声结构来阻挡噪声的传播
• 4.In urban construction, the use of anti-noise sound urban planning在城市建设中，采用合理的城市防噪声规划
4.Solid waste pollution
• Solid waste is generally called the garbage, waste of human metabolism of postconsumer waste and consumer items.（固 体废弃物就是一般所说的垃圾，是人类新 陈代谢排泄物和消费品消费后的废弃物 品。）
池，同时要积极做环境的保护者，宣传废旧电池的危害性，倡导回收电池，共同保护 美好家园。
That’s all , thank you !
• Pollutants into rivers, lakes, oceans, or groundwater, the water quality and sediment physical and chemical properties or biological community composition changes, reducing water use value and function of the phenomenon.（污染物进入 河流、湖泊、海洋或地下水中，使水质和 底泥的物理ห้องสมุดไป่ตู้化学性质或生物群落组成发 生变化，降低了水体的使用价值和功能的 现象。）
Types of solid waste pollution
• 1.“White pollution”“白色污染”
We used a lot of waste agricultural film, packaging, plastic film, plastic bags and disposable plastic tableware (hereinafter collectively referred to as plastic packaging) are discarded after use in the environment, to the great landscape and ecological damage(我们用过的大量的废旧农
噪声的传播方向
• 3.Establishment of noise barriers, or the use of natural barriers (slopes, hills), and the use of other insulation materials and insulation to stop noise transmission structure建立隔声屏障，或利用天然屏障（土坡、
