在当前面临水污染越来越严重的条件下,有必要再次向供水行业介绍国外膜技术的最佳应用情况。近百年以来,给水处理工艺仍然是混凝、过滤和消毒。微观上净水工艺继续改进,对给水处理的认识不断更新,理论继续深化,促进给水处理水平的提高。但是,宏观上并无重大本质的改变。到了二十世纪八十年代中期,在 Under the current situation of water pollution being more and more serious, it is necessary to introduce again to the water supply industry the best application of foreign membrane technology. Over the past century, the water treatment process is still coagulation, filtration and disinfection. Micro-water purification process to continue to improve, constantly updated understanding of water treatment, the theory continues to deepen to promote the level of water treatment to improve. However, there are no major changes in nature at the macro level. By the mid-1980s,
