development of human civilization, water resources have always been the source of life, the foundation of production and the foundation of ecology. However, in the process of accelerating industrialization and urbanization, the problem of water pollution has become increasingly prominent, which has become a bottleneck restricting sustainable development. In order to effectively meet this challenge, the state and local governments have successively issued a series of laws, regulations and technical standards on sewage treatment, aiming at protecting the ecological environment and promoting the harmonious coexistence of economy and society through scientific and reasonable sewage treatment.

First, sewage treatment requirements under the framework of policies and regulations

1. According to the provisions of People's Republic of China (PRC) Environmental Protection Law, Water Pollution Prevention Action Plan and other laws and regulations, all wastewater discharged into the environment must be properly purified to meet the national standards before it can be discharged.

2 governments at all levels need to establish and improve the urban drainage and sewage treatment facilities system, and strengthen the treatment of industrial sources, agricultural non-point sources and domestic sewage.

3. Encourage and support advanced and applicable technologies for advanced treatment, such as membrane separation technology and biofilter process, to improve the effluent quality and reduce the total amount of pollutants.

4. Implement strict monitoring and supervision system to ensure the stable operation of sewage treatment facilities and meet relevant emission limits.

Second, technological innovation promotes sewage treatment to a higher level

With the progress of science and technology and the change of social demand, traditional sewage treatment methods have been difficult to meet the requirements of the new era. Therefore, it is urgent to explore a more efficient, economical and safe new treatment mode. For example:

-Microalgae remediation system absorbs nitrogen and phosphorus in water by photosynthesis, which can not only purify water quality, but also generate renewable energy;

-Ecological wetland construction simulates the function of natural ecosystem, minimizing human intervention and achieving good landscape effect;

-Intelligent management platform uses the Internet of Things, big data analysis and other means to optimize resource allocation and improve management level and service efficiency.

Third, public participation in building a beautiful home

In addition to the efforts of professional organizations, every citizen should also assume his own responsibility, actively participate in daily activities such as saving water and sorting out garbage, and jointly safeguard the beautiful home on which we live. In addition, all sectors of society should also carry out extensive publicity and education activities to enhance people's awareness of environmental protection and form a good social trend.

In a word, Environmental Protection Rules for Sewage Treatment Norms is not only a specific technical operation guide, but also a key measure to guide the whole society to establish correct values and practice the concept of green development. face of all kinds of complicated situations that may be encountered in the future, we must maintain a high degree of vigilance, continuously improve relevant policies and mechanisms, increase investment in scientific research, work hand in hand, and make continuous progress towards the goal of blue sky, green water and clear water.
