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。
It is not enough to study mainly in degradation and pollution character of landfill leachate. So combined with a physical test in laboratory, the poilutants 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 density ofleachate changed little in whole time.
