I. Challenges ahead

1. The complexity of water quality has increased: industrial wastewater, domestic sewage and other sources are diverse, and there are many kinds of pollutants and the concentration changes greatly.

2. High treatment cost: Traditional sewage treatment methods often require a lot of energy consumption, resulting in high operating costs.

3. Insufficient recycling of resources: At present, many sewage treatment plants fail to fully tap the value of water resources and substances therein, resulting in waste of resources.

4. Low public participation: the lack of effective publicity and education mechanism makes the community's understanding of the importance of sewage treatment not deep enough.

Second, coping strategies

technological innovation

Application of biotechnology: such high-efficiency and low-cost technologies as activated sludge process and biofilm process can effectively remove organic matter and other harmful substances.

Combination of physical and chemical methods: coagulation, sedimentation, filtration, reverse osmosis and other ways are combined to achieve better purification effect.

Construction of intelligent management platform: use big data analysis to predict water quality change trend, optimize operation process, reduce energy consumption and improve system stability.

policy support

Formulate stricter discharge standards: urge enterprises to adopt more advanced technologies for sewage treatment and control pollutants from the source.

Encourage technological innovation and R&D investment: provide financial subsidies or tax incentives for related enterprises to promote the R&D and promotion of new technologies.

Strengthen environmental supervision: establish and improve the supervision system to ensure that all measures are effectively implemented.

Social mobilization

Enhance public awareness of environmental protection: Improve public awareness and support for water conservation and water source protection through education and publicity.

Encourage the community to participate in governance activities: establish a volunteer team, regularly carry out activities such as cleaning rivers and lakes, and form a good social trend.

Third, the conclusion

Facing the increasingly severe water pollution situation, we should actively respond to the call of the state, accelerate the pace of environmental protection transformation, continuously improve the sewage treatment capacity under the guidance of the government, scientific and technological innovation and the joint efforts of all sectors of society, and jointly protect every drop of precious water on this blue planet.
