摘要
采用浸没式膜-粉末炭生物反应器(MABR)工艺处理模拟沉后水,考察该工艺对浊度、氮类、有机物、颗粒物的去除效果,并对比聚氯乙烯(PVC)和聚偏氟乙烯(PVDC)中空纤维膜在此工艺中的净水效果和膜污染情况。结果表面,该工艺对浊度、氮类和有机物有较好的去除效果,可以将出水浊度控制在0.2 NTU以下;挂膜成功后,PVC膜对NH_4^+-N的去除率稳定在95%以上;COD_(Mn)、DOC、UV_(254)的平均去除率分别为38.8%、34.8%、47.0%。对比分析,发现2种超滤膜的过滤性能表现基本相当,但是PVDF超滤膜的污染情况比PVC更严重。
In order to contrast the purifying capacity and the pollution of two kinds of immersed ultrafiltration membranes that made of PVC and PVDF, a lab-scale test used submerged membrane adsorption bioreaetor （MABR） on simulated water after precipitation was carried out. The results showed that, the operation had good removal effect on turbidity, nitrogen, organic matters and particulate matters： the turbidity of effluent stabilized below 0.2 NTU, after BPAC was developed, the removal rate of NH4＋-N stabilized over 95%; the average removal rate of CODMn, DOC and UV254 by PVC membrane was 38,8%, 34.8% and 47.0% respectively. Analysis showed that two kinds of membrane have similar filter performance, but the pollution of PVDF membrane was serious than PVC membrane.
