摘　　要：采用活性转化剂、高效分散剂、聚凝剂Ⅱ等三种药剂处理延迟焦化装置焦炭塔吹气冷却废水。在进水COD、SS、油、硫化物平均浓度分别为107 563、900、190 488、967.7 mg/L时,出水分别为872、128、129、224.7 mg/L,去除率分别达95.0%、89.6%、97.1%、69.1%。出水水质优于切焦水及冷焦水的用水标准,已回用于切焦水及冷焦水系统,为企业带来了显著的经济及环境效益。The active conversion agent, high-effect dispersant and coagulant Ⅱ were used to treat cooling wastewater in coke tower in delayed coking unit. When the average concentrations of COD, SS, oil and sulphide in the influent are 107 563 mg/L, 900 mg/L, 190 488 mg/L and 967.7 mg/L, those indexes in the effluent are 872 mg/L, 128 mg/L, 129 mg/L and 224.7 mg/L respectively with the removal rates of 95.0% , 89.6 %, 97.1% and 69.1%. The effluent quality is superior to the standards for cut coke water and coke cooling water. It has been reused in the system, which brings significant economic and environmental benefits for the enterprise.
