Title:
DEVICE FOR WATER INLET DISTRIBUTION AND CONCENTRATED SLUDGE FERMENTATION TO STRENGTHEN MSBR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/050919
Kind Code:
A1
Abstract:
Disclosed in the present invention is a device for water inlet distribution and concentrated sludge fermentation to strengthen hydraulic shock resistance and a nitrogen and phosphorus removal function of a MSBR system. The device comprises a water inlet distribution device, a hydrolysis and fermentation tank body and a MSBR system connected thereto. The water inlet distribution device, the hydrolysis and fermentation tank body and the MSBR system are all connected to an external online control platform. The device can effectively remedy the problems of large loss of activated sludge, insufficient water inlet and carbon source and low nitrogen and phosphorus removal efficiency of MSBR systems under large-water-volume working conditions in the rainy season, carry out deep mining and utilization on a carbon source in the system, effectively reduce the costs of sewage treatment plants, and improve stability and reliability of the hydraulic shock resistance operation of MSBR systems. The device realizes in-situ sludge reduction and reduces operation energy consumption of sewage treatment plants while improving the nitrogen and phosphorus removal effect.
