摘要
通过对污泥降解情况和消化液理化特性的分析,研究了间歇曝气方式对消化系统污泥减量效果的影响。结果表明:在满足MLVSS降解率大于40%的要求下,缺氧/好氧消化工艺比传统好氧消化工艺最多可节省能耗33.3%。可强化反硝化作用并使消化液大致维持在中性水平。
Based on the analysis of MLVSS degradation and physicochemical properties of supernatant, the effect of intermittent aeration on sludge reduction in a digestion system was studied. The results showed that when the MLVSS degradation ratio was controlled to be higher than 40 %, which was the requirement of GB 18918-2002, A/AD process could save up to 33.3 % of energy cost compared with traditional aerobic digestion process. In addition,A/AD process could enhance denitrification and maintain the supernatant at neutral pH.
