【摘要】 垃圾渗滤液的处理一直是近几年污水处理领域的热点和难点问题。采用“吹脱-SBR-混凝沉淀-氯化”处理工艺对中晚期垃圾渗滤液进行实验研究,确定了各工艺的最佳运行参数,并对SBR的强化进行了新的探索。结果表明,该工艺可使垃圾渗滤液的COD值从1360 mg/L下降到93.6 mg/L,BOD5值从320 mg/L降低到28 mg/L,NH3-N的值从1098.6 mg/L下降到16.1 mg/L,出水色度接近无色,处理效果良好。更多还原

【Abstract】 Treatment of landfill leachate is a focus of researchers’ attention as well as a difficult problem in field of wastewater treatment.Study on the treatment of landfill leachate by separation NH₃-N-SBRcoagulation-chlorination process was carried out and reported in this paper.The optimum process conditions of the method were achieved,moreover,the effect of SBR had been intensified.The results show that COD of leachate is reduced to 93.6 mg/L from 1360 mg/L,BOD₅ is reduced to 28 mg/L from 320 mg/L,NH₃-N is reduced to（16.1 mg/L） from 1098.6 mg/L,The eliminating rate of the chroma is close to 100%.This process is feasible for the treatment of landfill leachate.更多还原
