摘要
HSMBR系统表现了对于COD高且稳定的去除效果。对于TN、TP,由于不排泥,污泥浓度的升高,并且填料内部的生物膜不断形成,以及在填料内部的污泥受曝气的扰动小,而变的较为密实,反应器内形成好氧、缺氧两种微环境并存,有利于系统对于TN、TP去除率的提高。
High and stable removal efficency of COD was achieved in the HSMBR system.According to the design,the system needed no sludge withdraw,so after the start-up of the system,the sludge concentration increased.The biofilm grew continuously within the packings where they were disturbed very little by aeration.Therefore both aerobic and anaerobic conditions co-existed in the reactor,which was favourable to improve the removal of TN and TP in the system.
