| 摘 要： | 通过3组平行试验,验证了生物砾石接触氧化法处理生活污水的可行性.结果表明:连续曝气的处理效果最佳.在3组试验装置的好氧生物膜中,检测出6种微型生物:钟虫、草履虫、轮虫、线虫、盾纤虫和体虫.其中,体虫未在间歇曝气装置中出现.连续曝气装置中检测到的微型生物种类与数量均多于间歇曝气装置.微型动物对剩余污泥减量的贡献可归纳为:增长食物链;直接对污泥进行摄食和消化,在减少污泥容量的同时增加污泥的可溶性;利用微型动物来增强细菌的活性或增加有活性的细菌数量,从而增强细菌的自身氧化和代谢能力,减少剩余污泥量.

| Abstract: | Microzoon species and their numbers on the biofilm of carrier and their function to excess sludge demineralization in 3 kinds of gravel contact oxidation reactor(GCOR) were studied by microscope examination.The treated water qualities indicated that the continued aerating equipment was better than the batch equipments(2h/2h and 4h/4h for aerating/aerating stop).Six kinds of microzoon species were lorticella,paramecium,wheel animalcule,nematode,uronema-like ciliate and aeolosma hemprichii.A different kinds of microzoon contributed to excess sludge decrement were associated with lengthening the food chain,predating bacteria directly,strengthening the bacteria activity. |
