陕西理工学院毕业设计某生活垃圾填埋场垃圾渗滤液处理工艺设计作者:张欢乐(陕西理工学院化学与环境科学学院环境工程 1102 班陕西汉中 723000 ) 指导教师:刘瑾[ 摘要]: 垃圾填埋过程中伴随有垃圾渗滤液的产生,垃圾渗滤液是种特别难处理的并且有毒有害的高浓度有机废水,这种废水的处理是当前必须首要解决的问题,若这种有机废水不能得到有效处理不仅会引起地表水、地下水以及土壤的严重二次污染,而且相应的生态系统和人体健康也受到很大威胁。本设计处理量为 150 吨每天。采用上流式厌氧污泥反应床( UASB )- 生物接触氧化池组合工艺,并且对吹脱塔、上流式厌氧污泥反应床( UASB ) 、生物接触氧化池等主要构筑物进行设计说明和计算。该工艺技术成熟、操作简单占地面积小、投资少、运行费用低、处理效果稳定,经处理后渗滤液经处理后出水水质标准可达到《中华人民共和国污水综合排放标准》( GB8978-1996 )中规定一级标准。[ 关键词]: 垃圾渗滤液,氨氮,生物接触氧化陕西理工学院毕业设计 A Landfill Leachate Treatment Process Design Zhang Huanle (Grade10,Class 2, College of Chemical & Environment Science, Shaanxi University of Technology,Hanzhong 723000, Shannxi) Tutor: Liu Jing Abstract : Landfill process is panied by the generation of leachate, landfill leachate isa kind of special refractory and hazardous high anic wastewater, the wastewater is currently must first solve the problem, if anic waste can not effective treatment not only causes serious secondary pollution of surface water, groundwater and soil, and the corresponding ecosystems and human health are also under great thre at. The design capacity of 150 tons per day. The reaction using upflow anaerobic sludge bed (UASB) - biological contact oxidation bined process, and the stripping tower, upflow anaerobic sludge reactor bed (UASB), biological contact oxidation ponds and other major structures design and calculation instructions . The technology is mature, easy to operate small footprint, low investment, low operating costs, stable treatment effect, after treatment the treated leachate water quality standards can be achieved, "People's Republic of China Integrated Wastewater Discharge Standard" (GB8978-1996) the provisions of the standards. Keywords :Landfill leachate, Ammonia nitrogen , Biological contact oxidation 陕西理工学院毕业设计目录引言................................................................................................................................................................ 1 1概述...............................
