Key innovations
The innovation lies in the coordinated treatment of activated sludge and biomembrane, which achieves short process flow, less sludge reflux, low operating costs, small land occupation, and a wide application range.
Potential economic benefits
Reduce operating costs by 18-31%, reduce sludge reflux by 40-80%, save project investment, reduce floor area, and at the same time, effluent meets the standards, sludge is easy to treat, and the comprehensive economic benefits are significant.
Potential climate benefits
Reducing operating costs by 18%-31% directly reduces energy consumption and related carbon emissions. Reducing sludge reflux by 40%-80% and easily handling sludge reduces energy consumption and transportation carbon footprint.

Solution details

Introduction to the results:

The invention is a sewage treatment equipment with a synergistic effect of activated sludge and biomembrane, which is suitable for treating petrochemical industry wastewater and low-concentration and high-concentration production or domestic sewage wastewater. The treatment process has stable treatment effect and reliable operation, and the effluent quality can reach the first-class standard of the national emission standard; the generated sludge has good sedimentation properties and is easy to treat; compared with other treatment equipment or structures, the process flow is short, and the sludge reflux volume is reduced by 40% to 80%, and the operating cost is reduced by 18% to 31%. The combination of multiple treatment processes is achieved through the combination of internal and external components of the treatment equipment, and the operation mode is flexible, saving project investment and reducing floor area.
