摘　　要：针对垃圾厌氧填埋渗滤液在直接回灌初期会出现严重的酸积累现象,分析研究了垃圾准好氧填埋与厌氧填埋的渗滤液直接回灌后的出水水质,发现采用准好氧垃圾填埋的体系内所含挥发性脂肪酸量和COD量比厌氧填埋柱低得多,不存在酸积累现象;从整个降解过程看,准好氧填埋加快了COD的降解速率,加速了垃圾体的稳定化进程;另外,环境温度对垃圾体的降解速率影响很大,较高的温度能够加速垃圾体的降解速度。The serious acid accumulation phenomenon is occurred when anaerobic landfill leachate was recycled to the landfill at the initial stage. To counter the issue, the water quality of leachate which came from semi-aerobic laboratory column and anaerobic column respectively was studied. The results indicate that VFA and COD contents of semi-aerobic landfill leachate are greatly lower than that of anaerobic landfill, so the acid accumulation phenomena does not occur. In the process of degradation, semiaerobic landfill greatly accelerates the degradation rate of COD and the stabilization of solid waste. Furthermore, the degradation rate of solid waste is affected by temperature of surroundings significantly, and higher temperature can accelerate the degradation rate of landfill.
