摘　　要：对处理焦化废水的两种工艺的试验研究表明 ,采用水解酸化—好氧生物处理较单一好氧生物处理可取得良好的效果。水解酸化作为焦化废水的预处理比较适宜。当实际焦化废水进水 CODcr浓度为 2 2 14 m g/ L ,水解酸化停留时间12 h,好氧曝气时间 18h,间歇动态试验出水 CODcr浓度为 172 m g/ L 时 ,CODcr的去除率达 92 .2 3 % ,满足污水综合排放标准 (GB8978-96)The experimental research on two processes of treatment of coking wastewater shows that adopting hydrolytic acidification-aerobic organisms treatment can get better results than adopting single aerobic organisms treatment. The hydrolytic acidification is more suitable to be a pretreatment for coking wastewater. When inlet CODcr density of actual coking wastewater is 2214mg/L, retention period of hydrolytic acidification is 12h, aerobic aeration period is 18h and outlet CODcr density obtained from intermittent dynamic test is 172mg/L, the removing ratio of CODcr is up to 92.23%, satisfying comprehensive sewage effluent standard (GB8978-96).
