采用后继混凝沉淀的A/O工艺对含酚、氰的焦化废水进行了处理,运行结果表明:废水中酚质量浓度从287～681 mg/L降至1.0 mg/L以下,氰化物质量浓度从0.72～11.4 mg/L降至0.5 mg/L以下,完全达到了<污水综合排放标准>(GB 8978-1996)的二级排放标准;COD_(Cr)从3 879～6 378 mg/L降至116.1～184.2 mg/L.氨氮从145.6～200 mg/L降至11.64～25.26 mg/L.大多数时间达到排放标准.

Aerobic/anoxic(A/O) process followed by flocculation-sedirnentation has been used for treating coking wastewater containing highly concentrated phenol and cyanide. The result indicates that the mass concentration of phenol decreases from 287-681 mg/L to 1.0 mg/L, mass concentration of cyanide decreases from 0.72-11.4 mg/L to 0.5 mg/L. The effluent quality can meet the second class criteria specified in Integrated Wastewater Discharge Standard (GB 8978-1996).The COD_(Cr) decreases from 3 879-6 378 mg/L to 116.1-184.2 mg/L, NH_4~+-N decrease from 145.6-200 mg/L to 11.64-25.26 mg/L. The effluent quality can meet the second class criteria in most time.
