摘要
结合国外关于好氧颗粒污泥的研究成果,论述了有关好氧颗粒污泥形成过程中的影响因素,如沉降时间、水流剪力、溶解氧(DO)、胞外多聚糖(EPS)等。介绍了好氧硝化颗粒污泥、亚硝化颗粒污泥、同步硝化反硝化颗粒污泥及同步脱氮除磷颗粒污泥等生物脱氮的研究现状,指出了连续流条件下好氧颗粒污泥亚硝化反硝化及颗粒污泥活性恢复等研究方向。
On the base of foreign study results about aerobic granular sludge, this paper summarized some effeeting factors on the formation of aerobic granular sludge such as settling time, water shear force, dissolved oxygen and extraeellular polymeric substance （EPS）. The researching status about nitrification granule, short-cut nitrification granule, simultaneous nitri- fication and denitrification granule as well as simultaneous nitrification - denitrifieation and phosphorus removal granule was discussed. And studying direction such as short-cut nitrification and denitrification under continuously flow and activeness recovery of aerobic granular sludge was put forward.
