复合生物反应器处理废水特性的研究

THE DEVELOPMENT OF WASTEWATER TREATMENT BY A HYBRID BIOLOGICAL REACTOR

研究了复合反应器中载体填充量及有机负荷对两相生物量的影响。结果表明：随载体填充量的增加，附着生物量及总生物量增加，但单个载体附着生物量减少。附着生物量及附着生物量与总生物量的比值随有机负荷的增加而增加，说明复合反应器在较高负荷下运行时，附着生物量对有机物的去除起主要作用。

The effect of volumetric capacity of carriers and organic loading rates on the development of suspended and attached-growth biomass is investigated in this paper.Results demonstrate that the total biomass increases with the increasing volumetric capacity of carriers,but the biomass attached on each carrier cube decreases.The attached biomass and the ratio of the attached biomass to the tatal biomass will increase with increasing loading rates,which implies that the attached biomass will play a major role in removing organics at higher loading rales.
