摘　　要：研究了石灰岩山区的裂隙水处理工艺,先用乙二胺四乙酸(EDTA)络合水中的铁离子,再利用膜法去除铁络合物和微生物。结果表明,通过投加EDTA络合水中的铁离子,选用超滤膜Ⅰ去除铁络合物,铁离子去除率为80.82%;然后利用碳化硅膜Ⅲ去除水中微生物,透过液中总菌数为23CFU·mL^(-1),微生物去除率为99.83%;最后采用阻垢剂Ⅱ消除膜结垢。处理后水质能达到或优于国家生活饮用水卫生标准,解决了石灰岩山区饮用水问题。We studied the treatment process of crevice water in limestone mountain areas.Firstly , we usedEDTA to complex iron ions in water , and then removed iron complexes and microorganisms by membrane meth -ods.The results show that the removal rate of iron ions is 80.82%through adding EDTA to complex iron ionsin water , and using ultrafiltration membraneⅠto remove iron complex.Moreover , the total bacteria count is 23CFU · mL^-1 in the permeate , and the removal rate of microorganisms is 99.83% through using silicon carbidemembraneⅢto remove microorganisms in water.Furthermore , we used scale inhibitorⅡto remove membranescaling.The quality of treated water can meet or exceed the standard of national drinkingwater.The process cansolve the problem of drinking water in limestone mountain areas.
