Purification agent manufacturers recommend wastewater treatment After pollutants into rivers, lakes or groundwater and other water, its content exceeds the natural purification capacity of water bodies, so that the water quality of the water body and the sediment physical, chemical properties or biome composition changes, Thus reducing the water use value and the use of the phenomenon, known as water pollution. A large number of inorganic and organic pollutants into the water, not only damage aquatic ecosystems, but also endanger human health, resulting in water quality of water and make people's industrial and agricultural production, life is affected. Strengthen the protection of drinking water intake The relevant departments should delineate the water source area, set up signs in the area and strengthen the greening of the water intake. Regularly organize personnel to check. From the fundamental elimination of pollution, to achieve the purpose of treating both symptoms. 2. Increase urban sewage and industrial wastewater treatment efforts to speed up the construction of urban sewage treatment plant for improving the water environment in our city has a very important role. At present, with the increase of urban population and the improvement of living standards of residents, the discharge of waste water in our city is constantly increasing while the urban sewage treatment plants have not been correspondingly increased, which will inevitably lead to the decline of water environment quality. Therefore, building more sewage treatment plants is an urgent matter. 3. To strengthen citizens' environmental awareness environment not only needs to be governed by them, but more importantly, to enhance people's awareness of environmental protection through various publicity campaigns. Residents of environmental awareness increased. Natural damage to the environment will be reduced. 4. Realize the utilization of waste water resources With the development of economy, industrial waste water emissions also increase, if only emphasis on the end of governance, it is difficult to achieve the purpose of improving the current state of water pollution, so we need to achieve the recycling of waste water. The main water pollution measures are the following three: (1) reduce and eliminate the discharge of pollutants in the amount of waste water. First, the reform process can be used to reduce or even eliminate waste water, or reduce the toxicity of toxic waste. Followed by the reuse of waste water. Try to use water reuse and recycle water system to minimize the discharge of waste water or to recycle the waste water after appropriate treatment. Such as electroplating wastewater closed loop, blast furnace gas washing wastewater by precipitation, cooling and then used for washing. Third, the concentration of pollutants in wastewater control, recycling of useful products. As far as possible, the raw materials and products lost in the waste water are separated from the water and recycled on the spot so as to reduce the production cost and reduce the concentration of waste water. Fourthly, the municipal solid waste and industrial waste should be treated well to avoid the pollution of the water body due to the precipitation or runoff erosion and dissolution. (2) Comprehensive planning, reasonable layout, and integrated regional management. The first in the development of regional planning, urban planning, industrial planning must consider the issue of water pollution, water pollution may occur, to take preventive measures. The second water pollution sources for comprehensive planning and comprehensive management. Third, put an end to any discharge of industrial waste water and municipal sewage, setting standards. The fourth with the industry should focus on wastewater treatment to reduce the number of sources of pollution, easy to manage. Finally there are plans to govern the water that has been polluted. (3) Strengthen monitoring and management and formulate laws and control standards. First establish national and local environmental protection management agencies to enforce relevant environmental laws and control standards, coordinate and supervise departments and factories to protect the environment and protect water sources. The second promulgated relevant laws and regulations, the development of water protection, control and management of water pollution specific regulations.
