Technical Points and Application of Chemical Phosphorus Removal Process in Dual Sludge System
The advanced treatment section of a certain sewage treatment plant adopts the process of coagulation and flocculation tank+radial flow sedimentation tank+filter cloth filter tank.the flocculation effect of the coagulation and flocculation tank is poor,the sedimentation effect of the radial flow sedimentation tank is poor,the effluent is prone to fluctuation,and the filter cloth filter tank is prone to blockage;The deep processing section has high operating costs and insufficient processing capacity.the organic combination of chemical sludge+activated sludge+coagulant/flocculant can greatly improve the flocculation effect of the coagulation and flocculation tank in the deep treatment section,improve the settling performance of the radial sedimentation tank,reduce the frequency of clogging in the filter cloth filter,significantly reduce the consumption of coagulants and flocculants,significantly improve the processing capacity of the deep treatment section,and reduce operating costs.
