With the acceleration of society, industrialization and urbanization, the problem of water pollution has become increasingly serious, which has become one of the major obstacles restricting sustainable development. In order to effectively meet this challenge, it is particularly important to establish a sound environmental protection operation mechanism for sewage treatment. This paper will discuss the importance of sewage treatment, existing technical means and how to build and improve the environmental protection operation mechanism.

First, the importance of sewage treatment

Water resources are indispensable basic resources for human survival and development. However, industrial wastewater and domestic sewage are directly discharged into natural water bodies without treatment or thorough treatment, which leads to deterioration of water quality, destruction of ecosystem and even threat to human health. Therefore, strengthening sewage treatment can not only improve environmental quality and ensure people's life safety, but also be of great significance for promoting comprehensive, coordinated and sustainable economic and social development.

Second, the main technical means of sewage treatment

At present, commonly used sewage treatment technologies mainly include physical methods (such as sedimentation and filtration), chemical methods (such as coagulation and redox) and biological methods (such as activated sludge method and biofilm method). These methods have their own characteristics and are suitable for different types of sewage treatment. In recent years, with the progress of science and technology, some new high-efficiency and energy-saving technologies have been gradually developed and applied in practice, such as membrane separation technology and advanced oxidation process.

Third, build and improve the environmental protection operation mechanism

1. Construction of laws and regulations: formulate and improve relevant laws and regulations, clarify the responsibilities and obligations of the government, enterprises and the public in environmental protection, and provide legal basis for sewage treatment.

2. Technical innovation support: encourage and support scientific research institutions and enterprises to increase investment in research and development of new technologies for sewage treatment, promote technological innovation, and improve treatment efficiency and effectiveness.

3. Capital investment guarantee: establish a diversified investment system and increase financial support for the construction of sewage treatment facilities; At the same time, explore the market-oriented operation mode and attract social capital to participate.

4. Raise public awareness: Enhance the awareness of saving water and protecting water sources in the whole society through publicity and education, and form a good social atmosphere.

5. Strengthening supervision and management: establish and improve the supervision system, strengthen the supervision and assessment of the operation of sewage treatment facilities, and ensure that all measures are effectively implemented.

In a word, the effective management of sewage treatment needs the combination of government leading, market operation and social participation. Only in this way can we fundamentally solve the water pollution problem facing our country and promote the process of ecological civilization construction.
