摘　　要：针对膜生物反应器处理后的化纤污水水质特点和化纤装置循环水系统工况条件,研究开发了污水回用循环水水质稳定技术。该技术采用杀菌剂和复合缓蚀阻垢剂,在某企业化纤装置循环水系统应用2年的结果表明:现场监测试管平均腐蚀速率为0.042 mm/a,平均黏附速率为133.20 mg/(cm2.a),均优于中国石油化工股份有限公司循环水考核指标,完全满足生产装置对循环水的要求,具有显著的经济效益和社会效益。According to the characteristics of wastewater treated by member bioreactor （MBR） and operation conditions of circulating water system in chemical fiber unit, a technology of water quality sta- bilization for recycling wastewater to circulating water system was developed involving self-developed bactericides and compound corrosion-scale inhibitor. The 2-year application results of said technology in the circulating water system of a chemical fiber unit show that the average corrosion rate and adhering rate of this waste-reused circulating water is 0. 042 mm/a and 133.20 mg/（cm2 · a）,respectively,which is better than the SINOPEC performance assessment index of circulating system with fresh water. Adopting said water stabilized technology for MBR treated wastewater could well meet the requirements of production unit for circulating water; good economic and social benefits are obtained.
