【摘要】 利用改性硅藻土对老龄垃圾填埋场渗滤液进行了处理,中试结果表明改性硅藻土的后处理效果比预处理效果好。若提高pH值、增加改性硅藻土投量还可提高COD去除率。采用两级硅藻土反应器串联处理老龄填埋场渗滤液生物处理出水,COD去除率可达到57%。更多还原

【Abstract】 Pilot test was made on the treatment of leachate from mature refuse landfill by using the modified diatomite. The result shows that the post-treatment with modified diatomite is more efficient than the pretreatment. Increase of pH value and dosage of modified diatomite can improve the removal rate of COD. When two-stage diatomite reactor in series is used to treat effluent from the biological treatment system for mature landfill leachate, COD removal rate can come up to 57%.更多还原
