Aerobic/anoxic(A/O) process followed by flocculation-sedimentation was used to treat coking wastewater containing high-concentration of phenol and cyanide.The practical running data indicated that the phenol decreased to 1.0 mg/L from 288~680 mg/L,cyanide to 0.5 mg/L from 0.73~11.3 mg/L when the HRT and DO of A section was 7 h and less than 0.3mg/L,the HRT and DO of O section was 7 h and 3.5 mg/L,the PAC dosage was 1 012.3 mg/L,the PAM dosage was 4.2 mg/L and flocculation-sedimentation time was… CONTINUE READING
