Study on the Advanced Treatment Secondary Effluent of WWTPs by Coagulation

Abstract:

The secondary effluent of WWTPs can be treated by the coagulation advancedly. The laboratory results showed that, PFS and PAC had lower efficient for the treatment of pollutants, and the effluent can not meet the requirements, so they were not s uitable as the coagulant. The PSFA, produced by the laboratory, had a higher removal rate of pollutants, and the quality of effluent can meet the relevant requirements of the standards, so it can be used as the coagulant of advanced treatment. The results of the experiment showed that the optimal dosage of PSFA was 20mg/L, and the COD, SS, turbidity, chromaticity, and TP of effluent were 9.5mg/L, 4.9mg/L, 2.7NTU, 10times and 0.15mg/L respectively.
