| Abstract: | Mixed liguor suspended solids (MLSS) in biological reactor is important for the operation of activated sludge system,which mainly realized by adjusting the operation of sludge return system.This article proposed that,based on the variation of technique,an active control strategy for sludge return should be performed based on fluctuant of inflow and outflow,sludge settleability, etc.in municipal wastewater treatment plants for stable and efficient operation. |
