厌氧陈腐垃圾模拟柱对渗滤液COD和NH_3-N的处理特性
Decomposition behavior of leachate COD and NH_3-N in anaerobic MSW simulation column
摘要
Abstract
Decomposition efficiencies of leachate COD and NH3-N in anaerobic MSW simulation column were investigated by using decomposed refuse drilled in Asuwei landfill.Experiments were carried out at two compaction density levels in combination with simulating landfill compaction process.The results showed that vertical flow of leachate was significant at the column compaction density of 1.09 t/m3.At the recharging hydraulic loading of 18.6、28、37.2和46.5 L/t,the removal efficiency of COD became stable and its average and the maximum value were 82.4% and 90.1%,respectively.Concentration of NH3-N in effluent was in the range of 415 mg/L to 700 mg/L and average value was 549.3 mg/L.The removal efficiency of COD and NH3-N in leachate selfrecirculation mode were only 11.5%,and 11.8%.Therefore,it was suggested that the fill process treatment of landfill in northern plain need to be further improved.The landfill vertical permeability uniformity and self-degradation of the garbage body are the key factors in reducing leachate pollution.关键词
