Membrane combined Advanced wastewater treatment system which applies Trisectional aeration and Changed inflow course and it's operation methods

摘要

The invention and give up to three minutes to change the way you apply submerged membrane flow coupled sewage advanced treatment methods for that, in the present invention, the anaerobic tank; Arranged in parallel and two alternating inlet reactor operated as a waiver to three minutes (the first and second reactors); Submerged aerobic membrane separator tank; Dissolved oxygen reduction actions; As the wastewater treatment system of sludge storage tank to the default configuration operating method it is provided. Wastewater advanced treatment method of the present invention can selectively increase the nitrogen and phosphorus removal efficiencies and increase the overall utilization of the organic material increases the efficiency of nitrogen and phosphorus removal. In addition to driving the MLSS within the reaction tank in the present invention as 6,000~8,000 mg / L level to improve the removal efficiency compared to conventional MBR process, and also can greatly reduce the amount of conveying the sludge to the outside its sludge conveying effect energy costs and the operating costs can be reduced.
