【摘要】 UASB是运用最为广泛的厌氧反应器,改良UASB的结构,使活性污泥与废水充分混合,大大提高了UASB的处理负荷,在UASB反应器内水力上升流速和沼气上升流速的共同作用可以确定离散系数D,指出了D值的范围与颗粒污泥形成的关系。简述了颗粒污泥的形成机理、形成过程、影响因素与抑制其生长的物质。更多还原

【Abstract】 UASB reactor is a kind of the wide application anaerobic reactors, modified structure of the traditional UASB can make active sludge fully mix with wastewater to raise volumetric loading rate of UASB. The effect both velocity of flow and the marsh gas to granular sludge can form a dispersed coefficient D together. The scope of D’s value has relationship with the formation of granular sludge. The formation mechanism, formation course, influence factors and the matter of restraining growth of granular sludge were described briefly in this paper.更多还原
