AI Technical Summary

Technical Problem

The carbon-nitrogen ratio in existing domestic sewage treatment is relatively low, resulting in poor biological nitrogen removal effect, and additional carbon sources are added to increase costs and increase the difficulty of sludge treatment.

Method used

A reaction device for internal carbon source conversion and storage of upflow sewage is designed, and the baffle partition and integrated clarifier are used to achieve uniform mixing and separation of sewage and sludge, and the dependence on external carbon source conversion reaction is reduced, and high-efficiency denitrification is used to achieve high-efficiency denitrification.

Benefits of technology

It can effectively reduce nitrogen content without adding additional carbon sources, reduce treatment costs and sludge production, simplify the sludge treatment process, and eliminate the need for mechanical drive, which is energy-saving and environmentally friendly.
