陕西理工学院毕业设计某垃圾填埋场渗滤液处理工程初步设计（陕西理工学院化工学院环境工程1102班，陕西汉中723001）指导教师： 摘要：本设计针对400t/d的垃圾填埋场渗滤液的处理工艺进行设计。渗滤液废水水质复杂，属于典型的高浓度难降解有机污染废水，其水质特点表现为有机物含量高、COD、BOD高、pH低等特点。设计采用“吹脱→与ABR→SBR→活性炭吸附深度处理”工艺对垃圾填埋场渗滤液进行处理。废水水质CODBODSSNH3-N9000mg/L3600mg/L1200mg/L1500mg/L渗滤液经本工艺处理后，COD、BOD、NH3-N及SS的去除率分别为98.9%、99.2%、98.4%及97.5%，满足《生活垃圾填埋场污染控制标准》（GB16889-2008）一级排放标准。 关键词：渗滤液；吹脱；ABR；SBR；活性炭吸附 Design of Municipal Solid Waste Landfill Leachate Treatment Process (Grade2011,Class02,Major environmental engineering，Shaanxi University of Technology，Hanzhong 723000，Shaanxi）Tutor:Li Chen Abstract: Design of 400m3/d of municipal solid waste landfill leachate treatment process was proposed. Leachate with complex substances was typical and difficultly degraded effluent that contains concentration of organic pollutants. It has the features of high organic content, CODCr, BOD5, and low pH values. Municipal solid waste landfill leachate was treated by the process of “air stripping→ABR→SBR→active carbon adsorption” with the wastewater quality of 9000mg/L COD, 1200mg/L SS, 3600mg/L BOD, 1500mg/L NH3-N. After the leachate was treated by the process, the removal rate of COD, BOD, NH3-N and SS was about 98.9%、99.2%、98.4% and 97.5% , and the quality of water met the First Grade Standard of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste （GB16889-2008）.
