北神树垃圾填埋场渗滤液水质分析

以北京市北神树垃圾卫生填埋场渗滤液为研究对象,分析测定了水样的化学需氧量、生物需氧量、氨氮、含油量、浊度、色度、电导率等常规指标及17种无机离子含量,了解了水样的组成、成份和性质;用膜分离-光谱扫描法和傅里叶变换红外光谱测定了垃圾渗滤液中有机物的分子量分布和主要的官能团结构;综合评价了垃圾渗滤液的水质状况.实验结果表明,垃圾渗滤液属于高浓度有机污水,是垃圾填埋场的主要污染源.本文研究成果可为今后国内城市垃圾卫生填埋场渗滤液的处理、规划和设计提供一定的依据和参考.

Analysis of water quality of Bei Shen-shu Landfill Leachate

In this paper, we have analyzed 17 abio - ions of water samples, involved in CODCr, BOD5, NH3-N, oils, turbidity, chromaticity color and electroconductibility involved with the Bei Shenshu Landfill beaehate of Beijing as a subject of case study. Then an investigation was done as to the assessment of the general water quality of the underground water in the leachate. Molecular weight distribution of organics as well as their influence on the water quality of the landfill were also tested and evaluated by using the membrane separate- spectrum scan and FT- IR method. The experimental results show that the landfill leachate has high - concentrated organic contaminants, which turned to be one of the main pollutant sources of the landfill and the surrounding areas. What has been done in this research can be used as a reference to the designing of the domestic landfill leachate treatment for the future.
