| Abstract: | The flocculations of biological treated coking wastewater by FeCl3,PVC and PFS were studied.The PFS was selected as the best treatment agent.The results showed that when dosage was 600mg·L-1,pH value was 6.8,settling time was 30 minutes,the CODCr and chroma removal rates were 87.4% and 85.5%.The remaining contents of CODCr and chroma reached the national level of industrial wastewater discharge standards. |
