在SBR反应器中驯化培养好氧颗粒污泥。考察颗粒污泥物理性能变化和有机物降解效果，研究好氧颗粒污泥在低浓度有机废水中的适应性。实验结果表明，污泥颗粒化进程快，反应器运行第14天时，出现粒径为3~6 mm，表面光滑有光泽的颗粒污泥，对COD的去除率保持在85%以上；降低COD 后，NH3-N、TP 的去除率分别为74%和90%；系统对甲醇有去除作用但效果不理想，最终去除率只达到24.28%。

The aerobic granular sludge has been cultured in a sequencing batch reactor(SBR). The physical capaci-ty change of aerobic granular sludge and degradation effectiveness of organic matter are investigated. Moreover ,the adaptability of aerobic granular sludge in low-concentration wastewater is inspected. The results show that the sludge granulation proceeds fast. When the reactor has run for 14 d ,the granular sludge with a diameter of 3-6 mm and smooth and shiny surface appears. Its removing rates on COD maintains at 85%or more. After the COD gets lower , the removing rates of NH3-N and TP are 74%and 90%,respectively. It is detected that the system has removing ef-fect on methanol,but its effectiveness is not satisfactory,being only 24.38%,at last.
