膜生物反应器处理校园废水中污泥性能的研究

摘要

为了提高校园废水处理效果，减轻对环境的污染，使用膜生物反应器处理人工校园废水，探讨了反应器内污泥分别为颗粒污泥和絮状污泥时膜污染情况和污泥性能。结果表明颗粒污泥膜反应器内MLSS、SVI、Zeta电位分别为101.78%、43.31ml/g、-5.329mV，均好于絮状污泥膜反应器内的42.38%、130.82ml/g、-23.856mV，在污泥增长、污泥沉降性能和污泥疏水性能方面都好于絮状污泥膜反应器。%In order to improve wastewater treatment efficiency on campus and reduce pollution of the environ-ment, we used membrane bioreactor in wastewater treatment on campus.We explored the membrane pollution and sludge performance within the reactor with granular sludge and floc sludge.The results showed that MLSS、SVI、Zeta potential of granular sludge membrane reactor were 101.78%、43.31ml/g、-5.329mV,and MLSS、SVI、Zeta potential of floc sludge membrane reactor were42.38%、130.82ml/g、-23.856mV.Granular sludge membrane reactor were better than floc sludge membrane reactor in sludge growth, sludge settling properties and sludge hydrophobic performance.
