AI Technical Summary
Existing activated sludge aerobic biological treatment methods suffer from low oxygen utilization, poor mixing efficiency, and lack of filtration, which affects wastewater treatment efficiency and effectiveness.
A helical flow bioreactor is used, which extends the gas-liquid contact time and forms turbulence by setting up first, second and third circular aeration pipes and their microporous aeration discs, combined with helical guide plates and baffles, thereby improving oxygen utilization. The wastewater is filtered multiple times before treatment.
It improves aeration efficiency and oxygen utilization, enhances wastewater treatment effect and efficiency, simplifies the process of replacing and assembling filter plates, and ensures the stability and reliability of the equipment.
