摘　　要：珠江三角洲地区自来水中主要有毒有害物质是:有机物、消毒副产物、氨氮及亚硝酸盐。应用纳滤组合工艺技术对这类自来水进行了饮水深度处理试验研究。结果表明,活性炭 纳滤组合工艺可有效去除这类污染物,对有机微污染物去除率高达 80 %以上。The main micro-pollutants in tap water in the Pear River Delta area are organic matter, disinfection by-products, NH 3-N and nitrite.A deep treatment test to this type of tap water was designed and conducted by the combination technique of nanofiltration and other filtrations. The results show that this technique can remove about 90 % of the organic pollutants, and the purified water can reach very high standard.
