超声与碱联合预处理剩余污泥中温两相厌氧消化
Two-Phase Mesophilic Anaerobic Digestion of Waste Activated Sludge by Ultrasonic and Alkaline Pretreatment
摘要
Abstract
Based on municipal waste activated sludge(WAS) obtained from Xijiao WWTP (A/O process) in Changchun, the effects of combined pretreatment of ultrasound together with CaO were investigated on subsequent two-phase mesophilic anaerobic digestion. The results indicate that the average volatile solids (VS) reduction is approximately 49.4%, and moisture content of effluent sludge decreases from 97.6% to 93.8% after anaerobic digestion. The sludge flocs are completely broken down in two phases by scanning electron microscopy (SEM) analysis. NH4-N concentrations in two phases are enhanced during anaerobic digestion. However, there exists no significant phosphorus release in two phases.关键词
