【摘要】 采用膜集成技术对石化行业排放水深度处理后回用于生产进行了研究,确定了系统的工艺条件,考察了系统对排放水的深度处理情况,对有机物、悬浮颗粒等去除率平均达95%以上,对盐的脱除率达到设计要求,产水水质完全达到冷却水水质标准要求.系统长期运行稳定,经化学清洗,产水量基本保持恒定.更多还原

【Abstract】 In the study the conbition of continuous microfiltration (CMF) and reverse osmosis (RO) processes was used as means to purify deeply petrochemical wastewater for reuse. The removal of organic compounds and suspension particles is more than 95%,the salt rejection and the quality of the purified water come up to the standard of cooling water.The performance of the membrane system was stable and the permeat water flux kept roughly constant through regular chemical cleaning for a long time running.更多还原
