高岭土控制污泥膨胀的研究
Study on Sludge Bulking Control by Kaolin
-
摘要: 活性污泥膨胀一直是困扰人们的难题。本实验以人工合成污水为底物,利用间歇式反应器(SBR)通过投加高岭土来研究污泥膨胀的控制情况。同时分析活性污泥中的丝状菌形态。结果表明,投加高岭土来控制污泥膨胀效果非常显著,对出水水质影响甚微。Abstract: Sludge bulking is still a problem.Using artificial synthesis wastewater as the substrate and sequencing batch reactor(SBR),this paper studies on sludge bulking control by adding kaolin and analyses the morphology of filamentous bacteria in activated sludge.The results showed that adding kaolin can control sludge bulking effectively and has little effect on effluent.
