摘　　要：采用SBR工艺处理城市垃圾填埋场排除的渗滤液，在原水水质波动较大的条件下，取得较好的处理效果，COD，BOD，NH3-N，TN的去除率平均为86．1％，97．4％，94．5％和81．3％．在SBR时间效率试验中发现SBR在反应3-4h内，微生物降解速度较快，这段时间COD，BOD5，NH3-N的去除率占总去除率的90％以上，TN去除率占总去除率的75％左右．另进行SBR的串联处理试验，也取得较好的处理效果．Treatment of leachate in urban garbage landfill with SBR process is discussed in this paper. The results show that the application of SBR process has better performance under great fluctuation of influent water quality. The removal efficiency of COD,BOD5 ,NHa -N and TN is 86.1% ,97.4% ,94.5% and 81.3% respectively. In the SBR time efficiency experiment, it is found that the biodegradation speed of organic compound improves greatly in 3 - 4 hours. During this period, the removal ratios of COD, BODs, NHa - N is above 90% of the total removal efficiency, and the removal ratio of TN is greater than 75%. SBR series experiments are carried out in this paper also, and the result shows that the application of this method is effective.
