中文摘要	对生物反应器填埋场启动的优化方案进行了考察,以每周回灌渗滤液量分别为1.6,0.8,0.2m3的3个模拟试验柱(记作R1、R2、R3)和1个每周回灌0.1m3清水的对比试验柱(记作R4)为研究对象,分析试验柱进出水水质变化和填埋气体产生情况.结果表明,较高的回灌水力负荷能够加速垃圾中有机质的溶出,提高填埋气体的产生速率.R1~R4的CODCr净流出总量之比为6.75:3.74:1.16:1.00,累计气体产生量之比为100.00:7.92:4.78:1.30.启动初期采用较大的回灌水力负荷不利于生物膜的附着生长,可先采用较低的回灌负荷进而逐步提高.较大的回灌量有利于加速填埋场的稳定化,R1在45周时出水水质已呈现“老龄”渗滤液的部分特征,CODCr降低到1870mg/L,BOD5/CODCr降至0.12.气候条件对回灌渗滤液的污染负荷有重要影响,进水氨氮浓度旱季最高值3475mg/L,雨季最低值1274mg/L.生物反应器填埋场的启动时间宜选择在雨季.; The optimum start-up of a bioreactor landfill was studied. Three pilot-scale simulated test columns(denoted as R1, R2, and R3) with recirculated leachate 1.6m3, 0.8m3, and 0.2m3 per week, respectively, and a control column(denoted as R4) with recirculated pure water 0.1m3 per week were studied to analyze the variations of qualities of inflows and outflows as well as the generation of landfill gas. A relatively higher hydraulic loading could accelerate the hydrolysis of organic components in garbage and landfill gas generation rates. The proportion of net CODCr amounts flowing out of R1-R4 by mass was 6.75:3.74:1.16:1.00, while the proportion of cumulative landfill gas generation amounts was 100:00:7.92:4.78:1.30. At the initial stage of start-up, adopting higher hydraulic loading force was not favorable to the growth of the biomembrane, while it was capable of adopting lower hydraulic loading first and increasing it step by step. A larger recirculation volume accelerates the stabilization of the landfill. After 45 weeks, the quality of outflow of R1 took on partial characteristics of “old age” leachate, with CODCr reduced to 1870mg/L and BOD5/CODCr reduced to 0.12. Climate condition influenced the pollution loading of recirculated leachate, and the concentration of ammonia-nitrogen of the inflows had the highest value 3475mg/L in the dry season, the lowest value 1274mg/L in the rainy season. Rainy season is a proper time for the start-up of bioreactor landfills.; 2002深圳市科技局项目; 科技部国际合作项目
