【摘要】 垃圾渗滤液是造成水体富养化、水文资源质量下降的主要因素之一。为更好提升中国水体质量,通过基础物化处理方法,将垃圾渗滤液中污染性因子分为氨氮化合物、难降解物质、重金属离子三大类。在保持其它两种物质含量不变的前提下,应用取样分析法分别确定氨氮化合物、难降解物质、重金属离子三种物质对水文资源的污染影响。分析三种不同的影响结果可知,物化活性污泥复合、厌氧氧化沟-兼性塘、生物膜三种处理手段,是降低垃圾渗滤液对水文资源污染影响、提升水体质量的有效方法。更多还原

【Abstract】 Landfill leachate is one of the main factors that cause eutrophication and decrease the quality of hydrological resources. In order to improve the quality of the water body in China,the pollution factors in the leachate are divided into three categories: ammonia nitrogen compounds,refractory substances and heavy metal ions. On the premise of keeping the other two kinds of substances unchanged,the effects of ammonia nitrogen compounds,refractory materials and heavy metal ions on the pollution of the hydrology resources were determined by the sampling analysis method. The results of three different effects can be seen that physical and chemical activated sludge complex,anaerobic oxidation ditch-facultative pond and biofilm are three effective methods to reduce the impact of landfill leachate on the pollution of hydrology resources and improve the quality of water.更多还原
