Butyric acid,phenol,indol and polycyclic aromatic hydrocarbons are inferredin the solution phase of leachate by GC,and 53% of organic acids,18% of alcohol andphenols,and 7% of alkanes are detected in leachate by GC-MS.The colloidal structure oflandfill leachate is analyzed by determination ofξ-potential and the interfacial tension,whichprovide the basis to pretreatment by the coagulation and treatment by advanced oxidation.
首先测定了垃圾渗滤液的常规水质因子及污染物含量,并采用GC及GC-MS技术对垃圾渗滤液有机相的微观结构进行了分析,由GC谱图解析推断渗滤液的溶液相中含有丁酸或辛酸、苯酚、吲哚及多环芳烃等有机物;由GC-MS解析可知其有机物主要为有机酸,约占53%,其次醇及酚类约占18%,烷烃约占7%。

Whereas, the predicted results of ammoniac nitrogen degradations in case of different refuse densities display that once the refuse density is less than 535 kg/m3, the refuse density has little effect on the leachate ammoniac nitrogen degradation.(2) the diameters of leacheate collection pipes is also one of important factors to influence the leachate quality degradation.
但是,对不同压实密度的准好氧填埋场的渗滤液氨氮衰减预测显示,当压实密度小于535 kg/m~3时,其对准好氧填埋场的渗滤液氨氮降解效果影响不甚明显;(2)渗滤液收集管管径也是影响准好氧填埋场降解效果的重要因素之一。

另外,加沙的土质特点导致污水、垃圾沥滤液(leachate)等易于渗入地下水层造成污染,增加水层中的硝酸盐含量. 研究人员在加沙取样抽测的结果显示,有些井水中硝酸盐竟高达每升331毫克,而世卫组织规定的标准是每升50毫克.

然而,卫生填埋也产生了诸如填埋气(landfill gas)、渗滤液(leachate)等等诸多环境问题,并对附近地区的公众健康构成威胁.长期以来,填埋场渗滤液被认为是其周边地区地表水及地下水的潜在污染源[2.3],而且填埋场关闭以后,
