| Abstract: | A study on the treatment of expansible polystyrene wastewater by the process of neutralization-coagulation-hydrolysis acidification-biological contact oxidation-removal phosphorus by chemical agent was investigated in this paper.The results show that COD Cr,TP and SS and NH 3-N can be reduced from 1 940 mg/L,112 mg/L,592 mg/L and 23.6 mg/L to 70 mg/L,0.38 mg/L,26 mg/L and 0.32 mg/L by the process respectively,with 96.4%,99.7%,95.6% and 98.6% average removal rate respectively,which can meet the first-order of “Overall Sewage Discharge Standards”. |
