炼化污水是原油炼制、加工及油品水洗等过程中产生的一类废水，污染物的种类多、浓度高，对环境的危害大。本试验的目的是采用深度处理（膜法处理法）来处理公司各生产厂所排放的污水，作为回用锅炉补水和回用循环水。试验结果表明，废水通过本系统工艺的处理，COD、氨氮、石油类的去除率可达90％以上，而且后续的超滤装置能够有效地将悬浮物质量浓度降低到1 mg/L以下，各项水质指标均能达到出水目标。

Large quantity of effluents containing oil ,water and complicated pollutants pro-duced from the refinery process do extremely harm to our environment .The aim of our study is to investigate membrane technology (ultra-filtration and reverse osmosis ) for petrochemical wastewater treatment and recycles .The treated water could be recycled as compensative water for boilers and other utilizations . The experiment results show that the percentage removal of COD ,N H3-N and petroleum oil can achieve over 90% by this process ;after ultra-filtration ,the suspended solid can be decreased to less than 1 mg/L ;and the quality of treated water reaches the standard of petrochemical industry discharge and utilization .
