摘　　要：针对武钢焦化厂的循环冷却排污水,采用超滤-反渗透双膜工艺处理。经现场中试试验检验连续运行的可行性,并取得其运行参数和条件。试验结果表明,超滤出水的SDI<1.4,出水浊度在0.3 NTU以下,出水的水质均能满足反渗透进水要求。废水经双膜工艺处理后,系统脱盐率达98.0%以上,出水水质达到了循环冷却补充水的要求,实现废水的回用,减少了环境污染。The Dual Membrane Treatment Processes,Ultra Filtration（UF） and Reverse Osmosis（RO） was applied for treating the circulating cooling sewage from the coking plant of Wuhan Iron and Steel（Group） Corporation.The feasibility study of it was conducted in the pilot-scale experiment on the spot,with the parameters and conditions.The results of experiment showed that,the SDI and turbidity of ultrafiltration water was SDI1.4 and turbidity0.30 NTU,respectively.The effluent quality could meet the requirements of reverse osmosis process.After treated by Dual Membrane Treatment Processes,the desalination ratio of the circulating cooling sewage was above 98%.The outlet water quality could satisfy the indexes of the circulating cooling make-up water.This technology could not noly achieve recycle for wastewater but also decreased the environmental pollution.
