With the development of society and economy and the acceleration of urbanization, the problem of water pollution is becoming more and more serious. How to effectively control sewage and protect water environment has become an urgent problem to be solved. Under this background, it is particularly important to plan and implement the environmental protection arrangement of sewage treatment facilities reasonably. This paper will discuss the environmental protection measures in sewage treatment and allocation and its significance to building a green ecological society.

First, the importance of sewage treatment

1. Guarantee public health: Untreated or improperly treated sewage contains a lot of harmful substances, such as heavy metal ions and pathogenic microorganisms. Once these pollutants enter the surface water body or groundwater system, it will not only destroy the balance of the ecosystem, but also cause human diseases.

2. Maintaining the ecological environment: Good water quality is the basis for maintaining biodiversity. Through scientific and reasonable sewage treatment technology, we can reduce or even eliminate the negative impact of industrial wastewater and domestic sewage on rivers and lakes, and promote the recovery and improvement of the natural environment.

3. Realize recycling of resources: The purified reclaimed water can be used in agricultural irrigation, industrial cooling and other fields to realize effective reuse of water resources and alleviate the contradiction between supply and demand.

Second, the environmental protection arrangement of sewage treatment facilities

1. Source reduction control: advocate the concept of energy saving and emission reduction, and adopt various means to reduce sewage production in production and life; For the inevitable sewage, advanced technology should be used for pretreatment to reduce the difficulty of subsequent treatment.

2. Technological innovation and application: actively develop and promote the application of new technologies, new materials and new equipment for sewage treatment with high efficiency and low energy consumption, so as to improve treatment efficiency and reduce energy consumption and emissions.

3. Resource recycling: establish a perfect sludge disposal system to convert the available components into fertilizers or other useful products; Explore the rainwater collection and utilization system and increase the supply of non-traditional water sources.

4. Legal and policy support: improve the relevant laws and regulations system, clarify the responsibilities and obligations of all parties, strengthen law enforcement, and ensure that all measures are effectively implemented.

Third, the conclusion

To sum up, sewage treatment is not only a part of environmental protection, but also one of the indispensable key links to promote sustainable economic and social development. future, under the guidance of national policies, we have reason to believe that through the joint efforts of the whole society, a scientific and effective sewage treatment system will be established, leaving a blue sea and blue sky for future generations.
