摘要
城市生活垃圾填埋场项目环评工作中,其重点和难点是根据不同的自然环境,提出科学、合理、经济、有针对性的垃圾填埋渗滤液处理工艺和方式。垃圾填埋场渗滤液是难处理的高浓度有机废水,在填埋场不同服务时期,其渗滤液的水质及主要组分也在发生变化。本文结合国内外对渗滤液研究基础上,剖析垃圾填埋场渗滤液产生来源、水质特点、主要组分变化情况,深入研究渗滤液的预处理过程、物理化学法、生物处理法及土地处理法等方法的适用条件和优缺点对比,并提出垃圾填埋场对渗滤液的各种处理形式。目前垃圾渗滤液处理方法和方式虽然很多,但如何从源头上减少渗滤液的产生,找到既经济又合理的处理工艺,值得我们在环评工作中做进一步研究。
Emphases and difficulties of environmental assessment on project of landfill is to take a proposal of scientific, reasonable, economical and focused treatment arts and mode of Landfill Leachate according to the different kinds of nature environment. Landfill Leachate is a kind of high - concentration wastewater what is difficult to treat. The water quality and the main component of Landfill Leachate change at different serving period. The origin, characteristic and the change of component at different phase of landfill Leaehate were analysed cursorily based on the native and worldwide study of landfill Leachate. Further, the con trast of the reasonable condition and the process of pretreatment, physical and chemical method, biological method and land method were studied intensively. Treatment arts and mode of landfill Leachate during these years were summarized. At present, there are lots of meathods to treat the Landfill Leachate.But it is necessary to find one which can not only treat it from original, but also is economical and reasonable. It worth us to do some rearch further at our environmental assessment work.
