摘要
浮选法活性污泥固液分离受废水成分和活性污泥性质的影响，在有利的营养条件下，微生物能从悬浮状态完全同废水分离。在不利的营养条件下，污泥上浮效果变差。废水营养物质条件也影响污泥颗粒的表面电荷，从而影响到活性污泥的凝聚和浮选效果。
Activated-sludge flotation is influenced by the composition of the waste water and the properties of the activated sludge.Under optimal nutritive condition the biomass can be separted from the suspension almost completely.The flotation result cleteriorates under poorer nutritive condition.The nutritive condition also influence the surface charge of the sludge particles,which has a strong influence on floccualation and flotation result.
