Application Research of Magnetic Coagulation Sedimentation and Denitrifying Deep Bed Filter in the Advanced Treatment of Sewage Treatment Plants
For the purpose of improving the effluent quality,the Lugang Sewage Treatment Plant in Baoding City applies a combined process of"magnetic coagulation high-efficiency sedimentation"and"denitrification deep bed filter"in the sewage deep treatment project.This project adds magnetic coagulation high-efficiency sedimentation tank and denitrification deep bed filter after the original secondary treatment process of the sewage treatment plant.The effluent water quality data after deep treatment transformation shows that after the use of the magnetic coagulation high-efficiency sedimentation tank and denitrification deep bed filter,the concentrations of COD,SS,TP,NH3-N,and TN in the effluent of Lugang Sewage Treatment Plant are well controlled,and the effluent water quality is stable.After the renovation,the main indicators of the effluent from the sewage treatment plant(except TN)have all reached the Class Ⅲ standard for surface water,which is better than the design standard.
