| 摘 要： | 为了提高膜生物反应器的处理效果、减轻膜污染,采用试验研究方法,探讨了投加絮凝剂对污染物去除效果、膜通量衰减的影响以及膜表面特性的变化情况,并探讨了絮凝剂最佳投加量.结果表明:适量投加絮凝剂可有效改善污泥特性,磷的去除率从60%提高到85%,减缓膜通量衰减,小时膜通量衰减从原来的65.1%升至78.6%,说明投加絮凝剂是一种防治膜污染的有效手段.

| Abstract: | In order to improve the efficiency of membrane bioreactor(MBR) and mitigate the membrane fouling,the removal effect and the decline of the membrane flux as well as the change of the membrane surface feature were studied when the flocculants were added into MBR,meanwhile the optimal dose of flocculants were also investigated.The result shows that feeding flocculants appropriately can improve the feature of sludge effectively,raise the removal rate of phosphorus from 60% to 85%,retard the decline of membrane ... |
