摘　　要：在膜生物反应器基础上的自组生物动态膜反应器有其独特的性能。试验研究了 200 目不锈钢丝网为基材在曝气池内形成的生物动态膜的过滤性能,在普通混合液悬浮固体(MLSS)浓度约2200±200mg/L下,采用自流出水,考察了不同水头(Water Head)及初始通量对出水流量和SS的影响。结果表明:水头和初始通量对动态膜的形成具有关键作用,但同时对膜的堵塞也有相当大的影响。30cm是较好的操作水头,而初始通量小于0.62m/h时,基材上未形成有效的生物动态膜。试验中的通量高于0.1m/h,远远超过微滤膜生物反应器。The self forming dynamic membrane reactor in the operation of MBR has its unique characters. In this paper the filtration performance of the bio-dynamic membrane using 200-mesh stainless steel fiber sieve as carrier was studied.The effects of different water head and initial flux to effluent flux and SS were examined in the conditions of MLSS2200±200mg/L.The results showed that the water head and initial flux are essential to forming of dynamic membrane as well as fouling of membrane.The optimum operation water head is 30cm.With the inital flux less than 0.62m 3/m 2 ·h,the bio-dynamic membrane can′t be formed effectively.The flux in the experiment was more than 0.1 m 3/m 2 ·h which greatly exceeded that of MBR.
