摘    要: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1mg/L以下,各项水质指标均能达到出水目标。

关 键 词:超滤  炼化污水处理  废水

Abstract: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, NH3-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.
Keywords:ultra-filtration  refining wastewater treatment  wastewater
