常规UASB反应器与内循环UASB反应器在处理垃圾渗滤液中的应用比较

以垃圾渗滤原液或者经过稀释后的垃液废水为处理对象,在不经过任何预处理情况下由常规UASB反应器与内循环UASB反应器直接进行厌氧处理,通过对两组试验的对比及试验结果的分析,比较了两组反应器在整体处理效果、污泥颗粒化以及抗冲击负荷能力等方面的优劣,得出内循环UASB反应器对底物的处理更充分,具有更强的处理能力、更高的工作效率,其出水更适宜于好氧法做进一步处理.

Comparison of Uses of Conventional UASB Reactor and Inner Recycling UASB Reactor for the Landfill Leachate Treatment

Without pre-treatment the undiluted or diluted landfill leachate was disposed directly by the conventional UASB reactor and the inner recycling UASB reactor. Through comparison of experiments and analyzing the experimental results of the above treating crafts, the merits and the demerits were discussed from the whole treating efficiency, the granulation of sludge and the resistance to load changing. It was concluded that, by the inner recycling UASB reactor, the substrate had thorough oxygenolysis, the processing capacity and operating efficiency were better, and the outlet water was disposed more properly by aerobic treatment.
