UASB-ARF工艺处理垃圾渗滤液中试研究

A Pilot Scale Experiment Study on Leachate Treatment Using UASB-ARF Process

采用UASB-ARF工艺对垃圾渗滤液进行中试,分析了有机负荷、水温度、pH值、分解池水力停留时间以及药剂等对处理效果的影响。结果表明:此工艺处理垃圾渗滤液效果良好,UASB反应器进水COD负荷在低温环境下控制在2～3kg/(m3·d),中高温环境下控制在4～6kg/(m3·d),pH在7.6～8.3。由于受温度影响,建议在冬季ARF采用二次分解和二次控制。

A pilot scale experiment study on leachate treatment using UASB-ARF process was carried out,influence of organic load,water temperature,pH value,hydraulic power retention time in degradation pond and agentia etc,on treatment effect was analyzed.The result showed that the process has good treatment effect for waste leachate treatment,UASB reactor intake COD load should be 2～3 kg/(m3·d) under low temperature situation,4～6 kg/(m3·d) under medium and high temperature,pH value should be 7.6～8.3.Influenced by temperature,adopting secondery decomposition and secondery precipitation in winter was suggested.
