First, the importance of sewage treatment
With the development of economy and the growth of population, the discharge of various pollutants such as industrial wastewater and domestic sewage has increased year by year, which has caused serious pollution to natural water bodies and affected the quality of life and ecological balance of human beings. Therefore, strengthening the construction of sewage treatment facilities and improving treatment efficiency has become one of the key measures to solve the problem of water environmental pollution.
Second, the principle of sewage treatment configuration under the environmental protection layout
1. Adjust measures to local conditions: Select appropriate sewage treatment technologies and processes according to regional characteristics (such as geographical location, climatic conditions, economic development level, etc.).
2. Comprehensive consideration: Based on the local actual situation, the location, scale and technical scheme of sewage treatment facilities should be rationally planned from two aspects of economic benefits and social benefits.
3. Resource recovery and reuse: It is advocated to adopt advanced biological treatment or physical and chemical treatment methods to recycle useful substances in sewage, and at the same time reduce the demand for fresh water resources through reclaimed water reuse.
4. Technological innovation and application: encourage research and development of new technologies, new materials and new equipment with high efficiency and energy saving, and popularize them in practical projects.
5. Public participation and education: enhance the awareness and support of all sectors of society for environmental protection, and form a good atmosphere of water saving and emission reduction.
Third, the specific implementation strategy
Construction of decentralized small sewage treatment station: for rural and remote areas, promote the use of small integrated sewage treatment devices with less land occupation and low cost.
Establish a regional large-scale sewage treatment center: set up centralized sewage treatment plants in densely populated areas of cities and towns, and adopt advanced and efficient treatment processes to ensure that the effluent quality reaches the standard before discharge or reuse.
Implement rain and sewage diversion reconstruction project: optimize the existing drainage system structure, separate rain and sewage pipes, and avoid secondary pollution caused by mixed discharge.
Promote the harmless disposal of sludge: improve the sludge collection and transportation system and explore appropriate ways of reduction, stabilization and resource utilization.
In a word, scientific and reasonable sewage treatment configuration under the environmental protection layout is an indispensable part of the current social development. This requires the joint efforts of the government, enterprises and the public to jointly promote the cause of ecological environmental protection in China.
