双膜工艺作为一种有效的废水处理方法,已被炼化企业广泛采用.然而,该工艺在使用过程中会产生一定量的含有机物高盐反渗透浓水(ROCs).在国家排放标准对废水外排指标日趋严格的情况下,反渗透浓水直接外排已被禁止.因此,含有机物高盐反渗透浓水处理技术成为研究的热点.本文对炼化反渗透浓水处理技术研究进展进行综述和讨论.首先本文对不同炼化企业反渗透浓水的组成进行了汇总和分析;其次,对反渗透浓水中有机物的去除技术,如物理化学方法、高级氧化法和生化方法等,进行了详细讨论,并深入分析了新兴高级氧化工艺的机理和优缺点;最后对炼化反渗透浓水中盐回收技术进行了讨论.“,”The reverse osmosis concentrates (ROCs) with high concentration of chemical oxygen demand and salts are produced by a double-membrane technology,which has been widely used to treat the wastewaters from petroleum refinery enterprises.The ROCs are prohibited from directly discharging from environmental point of view and must be treated to comply with the tighter discharge limits of wastewater and solid wastes per the upgrading national emission standard.Therefore,effective technologies for the removal of organic matter and recovery of salts from ROCs have been committed to be developed.In this review,the recent progress on the treatment technologies of ROCs from petroleum refinery waste waters are summarized and discussed.Firstly,the compositions of ROCs,the basis of developing the treatment process,from several petroleum refinery plants are collected and analyzed.Subsequently,the removal methods of organic contaminants,such as physicochemical method,advanced oxidation method,and biochemical method,are elaborated in detail.Especially for some innovative advanced oxidation processes,including O3 oxidation,Fenton method,electrochemical oxidation,photocatalytic oxidation,and ozonation-based combination processes,and their mechanisms,advantages and disadvantages for the treatment of ROCs from industrial sources are emphasized comprehensively.Finally,the methods of salts' recovery from ROCs are also discussed briefly.
