| 摘 要： | 在适宜的条件下,活性污泥系统中可以生长出大量的原生动物和后生动物等微型动物,这些微型动物在活性污泥中起着捕食者的作用,它们可以通过捕食,将污泥转化为能量、H2O和CO2,从而使污泥量减少。蚯蚓生物滤池工艺、两段式生物反应器工艺和淹没式生物膜工艺是目前国内外常见的3种利用微型动物减少污泥产量的工艺,本研究介绍了这3种工艺的污泥减量效果,并分析了各自的优缺点。

| Abstract: | A large amount of microzoon can be produced in activated sludge system under proper conditions, and they can change the sludge into energy, H_2O and CO_2 through predatoriness, thus reducing the sludge.The earthworm biofilter, two-step bioreactor and submerged biofilm processes are the common three ones, by which the sludge can be reduced through microzoon.The effects of reducing the sludge by these processes are introduced, whose merits and demerits are analyzed. |
