A new type of fiberglass tubular self-forming dynamic membrane bioreactor (DMBR) and its application for treatment of landfill leachate on laboratory scale were studied. The results showed that the system worked with a average membrane flux 3.75 L/m2 x h) maintained by gravity filtration at a trans-membrane pressure (TMP) of 2 900 Pa for near 80 days. After the modification of membrane module, a higher membrane flux was achieved at a TMP of 1 450 Pa and the membrane flux could be maintained steadily at 6 L/(m2 x h) for a long time. At the same time, the formation and filtration performance of dynamic membrane (DM) was tested. The effluent turbidity was blow 1.0 NTU and the average removal of COD, BOD5 and NH4(+) -N in this system exceeded 71%, 96% and 98% respectively. Moreover, COD removal from the supernatant on an average of 19.34% was made only by the dynamic membrane.
研究了一种新型玻璃纤维管状自形成动态膜生物反应器(DMBR)及其在实验室规模处理垃圾渗滤液中的应用。结果表明,该系统通过重力过滤在2900 Pa的跨膜压力(TMP)下以3.75 L/m²·h的平均膜通量运行了近80天。对膜组件进行改造后,在1450 Pa的TMP下实现了更高的膜通量,且膜通量可长时间稳定维持在6 L/(m²·h)。同时,测试了动态膜(DM)的形成和过滤性能。出水浊度低于1.0 NTU,该系统中COD、BOD₅和NH₄⁺-N的平均去除率分别超过71%、96%和98%。此外,仅动态膜就能使上清液中的COD平均去除19.34%。
