Advanced treatment of municipal sewage
After secondary biochemical treatment, a deep treatment process is added at the back end of the secondary sedimentation tank to further remove suspended solids (SS) and total phosphorus (TP). The horizontal tube high-efficiency sedimentation technology is used, and the SS and TP of the treated effluent are ≤ 10mg/L and ≤ 0.3mg/L, reaching the discharge standard of Class A or even surface level IV water, which can be discharged beyond the filter tank.
