AI Technical Summary

Technical Problem

Sewage treatment in rural areas is difficult to collect in a centralized manner. Traditional sewage treatment methods are low in efficiency, high energy consumption, complex sludge treatment, and untreated sewage polluted water bodies. Nutrients such as nitrogen and phosphorus in rural sewage have not been effectively removed.

Method used

A rural rainwater and sewage separation integrated treatment device is designed, including an integrated flow box, an integrated biological treatment unit and a backwash filtration system. Combined with aerobic digestion, anaerobic digestion and precipitation functions, it is equipped with a sludge treatment system, including sludge receiving, conditioning, dehydration, stabilization and forming units, and uses spiral pressing technology and an aerobic digestion tank to optimize the ventilation system.

Benefits of technology

It has achieved efficient sewage treatment, reduced water pollution, reduced energy consumption, simplified operations, improved sludge treatment efficiency, and improved the level of rural domestic sewage treatment.
