应用有效微生物(EM)技术处理垃圾渗滤液的研究

Study on Treatment Landfill Leachate with Effective Microorganisms(EM)

针对垃圾渗滤液常规生化处理无法解决的问题 ,通过应用有效微生物 (EM)技术净化垃圾渗滤液的静态小试和稳定塘中试 ,研究了 EM技术对垃圾渗滤液主要污染指标的降解效果。试验结果表明 ,EM菌液对毒性大的高浓度垃圾渗滤液处理效果明显 ,主要指标的去除率达到46%～ 5 1 % ;EM菌液对难生化降解垃圾渗滤液的处理效果显著 ,主要指标的去除率达到 67%～89% ,是垃圾渗滤液生化处理的一种新技术。

In view of the landfill leachate problems that couldn't be solve with conventional bio-chemical method, we study the removal effects of various water quality indicators by treating landfill leachate with EM technology The experiment showed that the effect that the treatment toxic landfill leachate of high concentration with EM is remarkable The removal rates of major pollution indicators reach 46%～51%. For landfill leachate that is very difficult to degrade with bio-chemical method, the treating effects with EM technology is remarkable The removal rates of major pollution indicators reach 67%～89% It is a new method and technology for landfill leachate treatment
