Abstract

The invention discloses a synchronous denitrification and dephosphorization sewage treatment device for an immobilized microorganism CASS (cyclic activated sludge system). The synchronous denitrification and dephosphorization sewage treatment device comprises a pond. A water inlet tube is arranged at one end of the pond, a water outlet tube is arranged at the other end of the pond, a hollow gridding reaction box is disposed in the pond, immobilized microorganism carriers are arranged in the hollow gridding reaction box, and an aeration device is arranged at the bottom of the pond. The synchronous denitrification and dephosphorization sewage treatment device aims to overcome shortcomings in the prior art, is simple in structure, and is efficient and stable.

Description

technical field [0001] The invention relates to an immobilized microorganism CASS synchronous nitrogen and phosphorus removal sewage treatment device. Background technique [0002] In recent years, with the rapid increase of my country's urban population, more and more nitrogen and phosphorus nutrients have been discharged into water bodies, coupled with farmland runoff, etc., the phenomenon of eutrophication in water bodies has become more and more serious. Therefore, the discharge of urban domestic sewage has become the main control target of water environment problems, and the control of nitrogen and phosphorus is an important control target of urban sewage discharge and water environment protection. my country's "Urban Sewage Treatment Plant Pollutant Discharge Standard" GB18918-2002 implemented on July 1, 2003 has made clear and strict regulations on the discharge standards of nitrogen and phosphorus. CASS (Cyclic activated sludge system) is a full name of cyclic activ...
