生活垃圾渗滤液膜浓缩液处理工艺探讨

Discussion on Treatment Process of Domestic Waste Leachate Membrane Concentrate

随着我国经济的快速发展和人民生活水平的大幅提高,生活垃圾的产生量也有所增加。生活垃圾产生的渗滤液如果处理不当,可能会污染地下水耕地和土壤,危害人体健康渗滤液的安全处置越来越受到重视但产生的浓缩液量较大,约为渗滤液流入量的13%~30%,大量污染物在膜浓缩液中浓缩。如果不能安全处理,很容易造成二次污染。目前,生活垃圾渗滤液膜浓缩物的处理已成为我国生态环境保护领域的一个难点。

With the rapid development of our country′s economy and the substantial improvement of people′s living standards,the amount of domestic waste produced has also increased.If the leachate produced by domestic waste is not treated properly,it may pollute groundwater,cultivated land and soil,and endanger human health.Leachate More and more attention has been paid to safe disposal.However,the amount of concentrated liquid produced is relatively large,about 13%to 30%of the inflow of leachate,and a large amount of pollutants are concentrated in the membrane concentrate.If it cannot be treated safely,it is easy to cause secondary Pollution.At present,the treatment of domestic garbage leachate membrane concentrate has become a difficult point in the field of ecological environment protection in my country.
