【摘要】 针对垃圾填埋体的研究主要集中在垃圾降解方面,而渗滤液本身污染特性研究不足的现状,结合室内物理模拟试验,对不同温度下渗滤液流体中各类污染物指标、相关流体物理性质变化规律进行试验研究。结果表明,在厌氧条件下,较高的温度对于填埋初期渗滤液流体中污染物指标COD、VFA、pH、NH3-N以及渗滤液粘滞性的增长起到促进作用,同时也有利于COD、VFA、pH的衰减。在垃圾降解中后期,较高的温度也不能发挥对氨氮浓度的降低优势,而渗滤液密度在整个填埋期间没有太大的变化。更多还原

【Abstract】 It is not enough to study mainly in degradation and pollution character of landfill leachate.So combined with a physical test in laboratory,the pollutants indexes and related character of leachate were analyzed in different temperature.The results showed that in anaerobic condition,the higher temperature can accelerate COD,VFA,pH,NH3-N,viscosity growth of initial landfill stage,and beneficial to attenuation of COD,VFA,pH.The higher temperature has no distinct effect on attenuation of NH3-N in the mid and late refuse degradation densityof leachate changed little in whole time.更多还原
