摘要:垃圾滲濾液是垃圾填埋過程中，由于厭氧發酵、有機物分解、雨水沖淋等產生多種代謝物質，形成高濃度的有機廢水，對水體、土壤、大氣和生物都有不同程度的影響。文章闡述了垃圾滲濾液的來源及水質特點；對目前國內外垃圾滲濾液處理工藝及技術進行了綜述，并在此基礎上探討了垃圾滲濾液處理今后的研究方向。

　　　垃圾填埋過程中產生的滲濾液具有污染物濃度高、水質水量變化大等特點,是國內外污水處理的一大難題。本文綜述了垃圾滲濾液的預處理、主體工藝及深度處理技術,指出了預處理和深度處理的重要性,并對國內外幾大垃圾填埋場滲濾液處理工藝作了比較。

Abstract:Landfill leachate is organic wastewater of high concentrations, which contains several kinds of metabolic substances produced through anaerobicfermentation, organic decomposition and rain shower. Landfill leachate has influence of different level on soil, air and biology. The paper expounded the origin andthe water quality characteristics of landfill leachate and summarized the landfill leachate treatment technology and technique. It explored the research direction oflandfill leachate treatment in the future. 

　　　Appeared in the process of municipal landfill ,leachate had the characteristics of high concentration and great variationin composition and flow rate ,which made it became one of the most difficult problem in wastewater treatment. Leachate treatmentincluding pretreatment ,principal treatment and advanced post2treatment were summarized in detail and the importance of the pretreatment and advanced post2treatment were pointed out. Furthermore ,Some treatment processes at domestic and abroad were compared in the paper.

　　　針對垃圾滲濾液成分復雜、毒性大、可生化性差等特點，采用氨吹脫+水解酸化+好氧生物+生物活性炭處理工藝，對石家莊市峽石溝垃圾衛生填埋場的滲濾液進行了處理研究。結果表明：

　　　1)氨吹脫+水解酸化+好氧生物+反滲透處理工藝處理石家莊市峽石溝垃圾衛生填埋場的滲濾液，工藝流程短、簡便易行、效果好。出水COD、BOD5、氨氮均可達到《生活垃圾填埋場污染控制標準》(GBl6889．2008)標準。

　　　2)采用吹脫法去除滲濾液中的氨氮效果良好，且在吹脫前用石灰乳將滲濾液pH值調至10．5，氣液比在3120的條件下，去除率可高達70％。

　　　3)老化滲濾液可生化性很差，采用水解酸化工藝在去除部分有機物的同時，可進一步提高滲濾液的可生化性，經處理COD去除率可達到30．40％，可生化性可由原來的O．12提高到0．31，更適合后續好氧處理。同時水解酸化工藝對溫度和pH值的適應性較強，更適合垃圾滲濾液水質水量變化大的特點。

　　　4)采用好氧生物處理可有效的進一步降低水解酸化后的滲濾液，COD、BOD5、氨氮的去除率可分別達到98．5．99％、97．5．99％、99％。
