我国垃圾渗滤液处理现状及创业前景分析

Analysis on the Present Situation and Prospect of Landfill Leachate treatment in China

为了解决我国渗滤液处理能力的不足,现有渗滤液处理设施处理出水无法达到《生活垃圾填埋场污染控制标准》(GB 16889—2008)的排放要求,以及膜处理工艺产生的浓缩液难以处理等问题,课题对国内渗滤液处理和浓缩液处理技术进行调研,从工艺的适用性、稳定性、经济性、出水指标等角度来选出适合我国的渗滤液和浓缩液处理技术路线。该课题的研究对提升我国渗滤液处理工艺技术,减少垃圾渗滤液污染物排放总量有着积极的意义。

In order to solve the problems that the leachate treatment capacity in China is insufficiency,treated effluent of existing leachate treatment facilities cannot reach the emissions requirement of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste(GB 16889—2008), and the concentrated liquid produced by the membrane treatment process is difficult to treat, domestic leachate treatment and concentrate processing technology was researched. From the perspectives of process applicability, stability, economy, effluent indicators, etc., a technical route suitable for leachate and concentrate treatment in China was selected. The research has positive significance for improving the treatment technology of leachate in China and reducing the total discharge of pollutants from landfill leachate.
