对汽提后的炼油厂含硫废水进行了水解——两级好氧生物 膜处理试验研究，结果表明，当总停留时间为17h，进水COD平均为1000～2000mg/L时，处理 后出水COD小于200mg/L，氨氮小于40mg/L，酚、硫化物也都低于国家排放标准。对工艺特点 分析表明：各段生物膜中含有不同的优势菌种，使整个工艺处理负荷高，出水水质稳定。%Steam-stripping wastewater containing sulfide is tre ated by hydrolosis-biofilm process, and the character of the process is analyse d. The results show that when the total retention time is 17 hours, COD, NH3- N of effluent are less than 200mg/l and 40mg/l respectively, and phenol, sulphide of effluent all meet the national effluent standards. Each stage is composed of varied dominant microorganisms, and the whole system is stable with high loading.
