摘要
江苏省某简易生活垃圾填埋场存量渗滤液的COD和氨氮浓度较低,可生化性较差,渗滤液处理采用“预处理+超滤+反渗透”工艺,后期的渗滤液水质变差导致膜污染严重。利用芬顿法对渗滤液进行预处理,通过小试试验,芬顿法对COD的去除率能达到81.19%。对预处理工艺进行改造,改造后的运行结果表明,芬顿法预处理渗滤液可以明显改善膜系统的运行情况。
The COD and ammonia nitrogen concentration of leachate in a simple household garbage landfill in Jiangsu province is low,and the biochemical property of leachate is poor.The leachate treatment process adopts"pretreatment+ultrafiltration+reverse osmosis",and the leachate water quality deteriorates in the later stage,resulting in serious membrane pollution.Fenton method is used to pretreat leachate,the COD removal rate is investigated through a small test,and the removal rate can reach 81.19%.The operation results show that the pretreatment of leachate by Fenton method can obviously improve the operation of the membrane system.
