摘　　要：采用SBR,以生活污水为进水,在常温条件下,接种苏州某污水厂活性污泥,对好氧颗粒污泥进行培养,并对反应器的运行效能进行了研究。研究表明,经100多天的运行,培养出粒径在4-8 mm间,结构松散,外观灰白色的好氧颗粒污泥;用城市生活污水培养的颗粒污泥对污染物的去除效果不好,无明显的脱氮除磷能力。The laboratory-scale study was carried out on the cultivation and operational performance of aerobic granule sludge in a SBR with domestic wastewater at ambient temperature,and with activated sludge taken from a wastewater treatment Plant in Suzhou as the raw sludge feed.The results showed that the grey-white aerobic granule sludge of 4～8 mm in diameter was formed after more than 100 day＇s operation;and low COD,ammonium nitrogen and phosphorus efficient removal of granule sludge cultivated by domestic wastewater were obtained.
