以某污水处理厂的尾水为研究对象,进行了活性炭/纳滤组合工艺深度处理污水处理厂尾水中微量有机物的研究.结果表明,该组合工艺对COD_(Mn)、TOC、UV_(254)均有较好的去除效果,平均去除率分别达到42.09%、69.54%和78.53%,出水的平均浓度分别为5.90 mg/L、1.93mg/L和0.04 cm~(-1).纳滤膜对邻苯二甲酸酯类物质具有较好的截留效果,对邻苯二甲酸二丁酯、邻苯二甲酸二乙酯和邻苯二甲酸二乙基己基酯的平均去除率分别为78.91%、78.95%和70.69%.
以某汙水處理廠的尾水為研究對象,進行瞭活性炭/納濾組閤工藝深度處理汙水處理廠尾水中微量有機物的研究.結果錶明,該組閤工藝對COD_(Mn)、TOC、UV_(254)均有較好的去除效果,平均去除率分彆達到42.09%、69.54%和78.53%,齣水的平均濃度分彆為5.90 mg/L、1.93mg/L和0.04 cm~(-1).納濾膜對鄰苯二甲痠酯類物質具有較好的截留效果,對鄰苯二甲痠二丁酯、鄰苯二甲痠二乙酯和鄰苯二甲痠二乙基己基酯的平均去除率分彆為78.91%、78.95%和70.69%.

The combined process of activated carbon (AC) and nanofiltration was used to remove trace organic compounds in tail water of a sewage treatment plant. The results show that the average re-moval rates of COD_(Mn), TOC and UV_(254) are 42.09%, 69.54% and 78.53% respectively, and the aver-age concentrations in the effluent are 5.90 mg/L, 1.93 mg/L and 0.04 cm~(-1) respectively. Also, phthal-ic acid esters are effectively intercepted by the nanofiltration membrane, and the average removal rates of DBP, DEP and DEHP are 78.91%, 78.95% and 70.69% respectively.
