摘要
采用生物反应器 填埋场系统处理垃圾渗滤液 .结果表明 :该系统有助于渗滤液中有机污染物进行分相降解 ,产酸作用主要集中在填埋场 ,酸化率为 4 0 %～ 5 0 % ,产甲烷作用集中在UASB生物反应器中 ;系统对渗滤液的处理效果明显优于普通的卫生填埋场和渗滤液单独处理系统 ,并且有利于甲烷气体的收集和利用 .
The study utilizes the system combined bioreactor with landfill site to treat leachate. The results show that the system helped the degradation of the organic pollutants in the leachate to be divided into two phases, the hydrolytic fermentation and acid production phases mainly occurred in the landfill site ,the acidification rate was 40%～50%,the methane production chiefly occurred in the bioreactor(UASB). It treated the leachate significantly and benefits the collection and utilization of methane gas . Also, the system accelerates the process of degrading municipal solid waste and stabilizing landfill site.
