厌氧-好氧组合工艺处理制药废水的试验研究

Experimental studieson the treatment of medical wastewater by combined anaerobic and aerobic processes

采用上流式厌氧污泥床反应器-移动床生物膜反应器串联装置,处理含有大量氨基酸和皂素的制药废水。系统的总COD去除率平均在86%左右。当厌氧反应器的COD容积负荷为10～21kg/(m3·d),COD去除率平均为70%左右;好氧反应器的COD容积负荷率为2.48～2.87kg/(m3·d),COD去除率为59%。

The medical wastewater,which iscomposed of a large quantity of amino acidsand saponin,istreated by upward anaerobic sludge bed reactor(UASB)-moving biofilm bed united reactor(MBBR)processes,The total removal rate of COD is86%in the system.The removal rate of COD of UASB is70%,while the capacity of COD load is10 ～ 15kg / (m 3 ·d);The removal rate of COD of MBBR is59%,while the capacity of COD load is2.48 ～ 2.87kg / (m 3 ·d).
