Water resources pollution and its control

⒉ Establish urban sewage treatment system

Speeding up the construction of urban sewage treatment plant plays a very important role in improving the water environment. At present, with the increase of urban population and the improvement of residents' living standards, the discharge of urban wastewater is constantly increasing, but the urban sewage treatment plant has not increased correspondingly, which will inevitably lead to the decline of water environment quality. Therefore, it is urgent to build more sewage treatment plants.

C. Strengthen citizens' awareness of water resources protection

To improve the environment, it is not only necessary to manage it, but more importantly, to enhance residents' awareness of environmental protection through all aspects of publicity. Strengthen the education of young people to protect water resources, shoot educational films, do publicity activities, so that every flower in China in the future has the good character of saving and protecting water resources. Residents' awareness of environmental protection is enhanced, the behavior of damaging the environment will naturally decrease, and the problem of massive pollution of water resources will gradually decrease.

Realize waste water resource utilization

With the development of economy, industrial wastewater discharge will increase, if only pay attention to the end of treatment, it is difficult to achieve the purpose of improving the current water pollution situation, so we must realize the utilization of wastewater resources. In order to control the development of water pollution, industrial enterprises must also actively control water pollution, especially the discharge of toxic pollutants must be treated separately or pre-treated.

5. Strengthen the treatment of urban domestic sewage, industrial wastewater and initial rainwater

With the acceleration of the urbanization process, the discharge of urban domestic sewage and industrial wastewater is more and more large, and there are many problems in the pipe network constructed in the past, and it is impossible to effectively distinguish and treat domestic sewage, industrial wastewater, early rainwater and middle and late rainwater. Science and technology can be used to rationally transform the existing pipe network, so that sewage is discharged into the sewage treatment plant, and clean rainwater is directly discharged into the natural water body, so as to effectively reduce the pollution of rivers and lakes.

With the adjustment of industrial layout, urban layout and the construction and improvement of urban sewer network, the centralized treatment of urban sewage can be gradually realized, so that urban sewage treatment and industrial wastewater treatment can be combined.

Pictures of water purification

Filtration - precipitation (alum) - odor removal with activated carbon, color removal - disinfection (chlorine, bleach powder). There may be secondary pollution in the process of water pipe transmission, so it is necessary to boil sterilization when drinking, and use a clean cup. Families with conditions can install home health water dispensers

A small amount of it creates landfills

A small amount of landfills can be created so that waste water and gases can be treated and then discharged into rivers. Because landfills cover a large area and waste land resources, they should be created in small quantities.

Reduce water consumption

At present, the use of water resources in our country feels the tension of water resources on the one hand, and the waste is very serious on the other hand. Compared with the industrial developed countries, many units of water consumption in China is much higher. Large water consumption not only causes waste of water resources, but also is an important cause of water environment pollution.

Through the technological transformation of enterprises, the implementation of cleaner production, reducing the water consumption per unit product, multi-use of one water, and improving the reuse rate of water have been proved to be effective in practice.

⒐ Industrial restructuring

The natural purification capacity of water body is limited, and reasonable industrial layout can make full use of the natural capacity of the natural environment, turn the vicious circle into a virtuous circle, and play a role in economic development and pollution control. Shut down, stop, and transfer those enterprises that consume a lot of water, pollute heavily, and control pollution at a high cost. It is also necessary to adjust the agricultural structure that consumes a lot of water, especially in arid and semi-arid areas to reduce rice planting area, and take the road of water-saving agriculture and sustainable development.

⒑ Control pollution from non-point agricultural sources

Agricultural non-point source pollution includes rural living source, agricultural non-point source, livestock and poultry farming and aquaculture pollution. It is more difficult to solve non-point source pollution than industrial pollution and domestic sewage in large and medium-sized cities, and it needs to be controlled through comprehensive prevention and control and ecological agriculture demonstration projects.
