利用UASB反应器中温条件下处理高浓度淀粉废水，在COD容积负荷保持在10kg/(m³·d)时，COD去除率可达到90%以上。试验结果还充分证明，微量元素在厌氧消化过程中具有极为重要的作用。

A mesophilic UASB (Upflowanaerobic Sludge Bed)reactor is used for the treatment of wastewater from starch production.the testresults show that when the COD loading rate of the reactor remains 10 kg/(m³·d), the COD removal efficiency could be over 90%.Besides, the testalso proves that the trace element plays a very impo rtant part in the anaerobic digestion process.
