MVC工艺处理生活垃圾中转站渗沥液的试验研究

Treatment of Waste Leachate from Domestic Waste Transfer Stations by MVC Process

采用MVC技术处理垃圾中转站新鲜渗沥液,清水产生率达到90％以上,出水的SS低于检测限,CODCr为158～784 mg/L,TOC为14～200 mg/L,NH3-N为2.20～3.10 mg/L,TN为4～133 mg/L,TP为0.01～0.67 mg/L,去除率依次为99.9％、95.39％～99.15％、96.18％～99.83％、76.35％～82.56％、91.41％～99.52％和91.2％～99.9％,该技术对污染物有较好的去除效果,比膜处理技术有更好的工程应用优势.

The fresh leachate generated at waste transfer stations was treated by using MVC technology.The rate of clean effluent water can reach over 90％.In the discharge water,SS,CODCr,TOC,NH3-N,TN and TP were under detect limitation,158～784 mg/L,14～200 mg/L,2.20～3.10 mg/L,4～133 mg/L and 0.01～0.67 mg/L,with corresponding removals of 99.9％,95.39％～ 99.15％,96.18％～99.83％,76.35％～82.56％,91.41％～99.52％ and 91.2％～99.9％,respectively.The process had a better effect on pollutants,and had more superiorities than membrane treatment technology in engineering application.
