【摘要】：总体分析了中石化某煤化工企业所有膜法水处理相关领域的三大水处理站。重点突出了煤化工污水回用水站陶氏反渗透膜的长期运行工况。该污水回用水站的进水水源主要由除盐水站的浓水,循环冷却排污水以及煤化工生产中产生的有机污水构成。该水站的进水水质及其恶劣且不稳定。基于此点,该项目设计了一套很长的反渗透膜系统的预处理工艺,包括厌氧,缺氧以及好氧的主生化工艺;包括石灰纯碱法的软化工艺;包括溶气气浮的除油工艺;更包括浸没式超滤处理单元;从而全面保障反渗透的进水水质足够改善。总结了陶氏抗污染反渗透膜在经历初期运行不稳定后,经过工艺参数的调整后,长期稳定运行的工程应用经验。
[Abstract]:Three major water treatment stations in all the related fields of membrane water treatment in a coal chemical enterprise of Sinopec are analyzed. The long-term operating conditions of Dow reverse osmosis membrane for coal chemical wastewater reuse water station are emphasized. The intake of the sewage reuse water station is emphasized. The source of water is mainly concentrated water from desalination stations. The circulating cooling sewage and organic sewage produced in coal chemical industry are formed. The influent water quality of this water station is very bad and unstable. This project designed a set of long reverse osmosis membrane system pretreatment process, including anaerobic, anoxic and aerobic main biochemical process; Including the softening process of lime soda method; The oil removal process includes dissolved air floatation; It also includes immersion ultrafiltration processing unit; Therefore, the influent water quality of reverse osmosis can be improved enough. The engineering application experience of long-term stable operation of Dow anti-pollution reverse osmosis membrane is summarized after the initial operation is unstable and the process parameters are adjusted.
