Introduction

The national polluted water emissions increased by 31.5 billion tons in 1980 to 63.1 billion tons in 2002. Most urban groundwater polluted to some extent, and has a tendency to increase year by year. The use of the increasingly serious water pollution not only reduces the water functions, further aggravated the contradiction of water resource shortage, but also a serious threat to urban residents drinking water safety and health. For our life source being polluted, how should we respond?

1.The water resources and pollution situation in our country

1.1Water resources situation in our country

From The first national water resources census bulletin，By the end of 2011,there are 45000 reasons basin area of 50 square kilometers above, total length of 1.5085 million km. There are 22900 reasons basin area of 100 square kilometers above. There are 2865 natural lakes water is greater than 1 square kilometers with a total area of 7.8 square kilometers. The country has about 98000 reservoirs, with a total capacity of 98000 cubic meters. The national total of 638900 lakes water inlet, the earth's surface and underground water source is respectively 1.17 and 1847.

China's per capita water resources is only 2100 cubic meters, only 28% of the world's per capita.

In the northern region, water resource is very shortage, the Yellow River, huaihe river, haihe river three per capita water resources quantity respectively for the national average of only 30.1%, 21.6% and 12.9%.

China's per capita fresh water resources is only a quarter of the world's average, ranked 110 in the world, is one of the poorest countries in the world per capita water resources. Available water resources per capita is only 900 cubic meters, and unevenly distributed. The end of the 20th century, the presence of more than 400 cities in more than 600 cities has water supply shortage problem, the serious water shortage city more than 110, the national total water shortage of 6 billion cubic meters.

1.2Situation of water pollution in China

China's top ten river basin water quality success rate is 2/3, Local water quality is worrying，overall，

Through years of efforts, we have improved water quality in China, the top ten overall for watershed water quality mild pollution, but at local area, the water quality of local water environment pollution is still serious. Recently published in domestic academic journal "science bulletin", according to an
