活性炭/纳滤工艺深度处理污水厂尾水的研究

Activated Carbon and Nanofiltration for Advanced Treatment of Tail Water from Sewage Treatment Plant

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CODMn、TOC、UV254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5.90mg/L、1.93mg/L和0.04cm-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%。

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 removal rates of CODM,, TOC and UV254 are 42.09% , 69.54% and 78.53% respectively, and the average concentrations in the effluent are 5.90 mg/L, 1.93 mg/L and 0.04 cm^-1 respectively. Also, phthalie acid esters are effectively intercepted by the nanofihration membrane, and the average removal rates of DBP, DEP and DEHP are 78.91%, 78.95% and 70.69% respectively.
