摘　　要：向低浓度生活污水中投加絮凝剂 (壳聚糖 )和颗粒活性炭 (GAC)的试验结果表明 ,这两种物质对厌氧污泥的颗粒化均有促进作用 ,但不如在中、高浓度污水中明显。二者相比 ,GAC的效果更好一些 (反应器的运行稳定 ,耐冲击能力强 ,出水水质良好 ) 。Study was made by adding flocculent (Chitosan) and granular activated carbon (GAC) into the low strength domestic wastewater. The results show that both chitosan and GAC can promote the granulation of anaerobic sludge, but their effect in low strength wastewater is not as obvious as that in the medium and high strength wastewater. As compared with chitosan, GAC has better effect (steady operation of reactor, strong shock resistance, good effluent quality). The methanogenic filamentous bacteria predominate on the surface of granular sludge produced in all reactors.
