With the acceleration of society and urbanization and the continuous expansion of industrial production, the problem of water pollution has become increasingly serious, which has become one of the important factors restricting sustainable development. In order to meet this challenge, it is particularly important to build an efficient and environmentally friendly sewage treatment system. This paper aims to explore a sewage treatment framework model based on the concept of circular economy, and provide reference for realizing the recycling of water resources.

First, the importance of sewage treatment

Water is the source of life and plays an irreplaceable role in human survival and social and economic development. However, a large amount of wastewater produced in the process of industrialization is directly discharged into the natural environment without treatment, which not only seriously destroys the ecological balance, but also threatens people's health and safety. Therefore, strengthening sewage treatment and improving sewage treatment rate and quality are of great significance for protecting the environment and promoting harmonious economic and social development.

Second, the design principle of environmental protection sewage treatment architecture

1. Resource utilization: treat sewage as a renewable resource rather than a waste, and convert it into valuable substances or energy through advanced technical means, such as bioenergy and fertilizer.

2. Energy conservation and emission reduction: adopt low-energy and high-efficiency technical equipment for the treatment process to reduce the generation of secondary pollutants; At the same time, pay attention to the energy consumed in the process of recycling.

3. Eco-friendly: ensure that the treated water quality meets the requirements of relevant national standards and does not cause negative impact on the receiving water body; Actively use constructed wetlands to simulate the natural purification mechanism.

4. Public participation: enhance the awareness and support of all sectors of society for environmental protection, and encourage people to participate in water resources management and conservation activities.

Third, the specific implementation strategy

-Introduce advanced technologies such as membrane separation technology and advanced oxidation method to improve the sewage treatment effect;

-Establish and improve the urban rainwater collection and utilization system, reduce the burden of sewers and replenish underground water sources;

-Promote agricultural irrigation reuse projects and rationally allocate the ratio of industrial water to domestic water;

-Strengthen policy guidance and financial support, and provide necessary incentives for enterprises and individuals.

IV. Conclusion

To sum up, it is a long-term and arduous task to build a sewage treatment framework that not only meets the current actual needs but also adapts to the future development trend. This requires the joint efforts of the government, enterprises and the public to form a joint force. We have reason to believe that with the common concern and support of the whole society, China's sewage treatment industry will surely usher in a more brilliant tomorrow!
