垃圾渗滤液处理纳滤浓缩液的减量试验研究

采用1种纳滤膜和2种反渗透膜对垃圾渗滤液处理过程中产生的纳滤浓缩液进行处理,研究进水压力、回收率、膜通量对膜工艺运行稳定性、出水水质的影响。研究结果表明,在试验条件下垃圾渗滤液纳滤浓缩液可减量50%以上,反渗透产水指标满足《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)城市绿化及娱乐性环境用水-湖泊类的要求。

Experimental Study on the Treatment for Nanofiltration Filtration Concentrate of Landfill Leachate by Membrane

One kind of nanofiltration membrane and two kinds of reverse osmosis membrane technology have been used for the treatment of nanofiltration filtration concentrate and effects of inflow pressure ,recovery rate and membrane flux on the stability of nanofiltration and reverse osmosis membrane have also been studied .The research results show that nanofiltration filtration concentrate can be reduced above 50% decrement and the produced water by RO reaches the standards stipulated in the National Standards for Reuse of Urban Wastewater and Miscellaneous Uses (GB/T 18920—2002) of the urban green-ing and recreational water environment -lakes .
