运行工况对膜生物反应器内EPS及污泥特性的影响
Effects of Operation Conditions on EPS and Sludge Properties in Membrane Bioreactor
摘要
Abstract
Submerged membrane bioreactor (SMBR) was used to treat domestic wastewater. The influences of operation conditions (sludge burthen, aeration, pH value, etc) on the extracellular polymeric substances(EPS) and sludge properties in the reactor were investigated respectively, and the relation between EPS and sludge properties were discussed. The experiment results showed that EPS and amylase will decrease as burthen Ns or aeration increases, and amylose and protein sludge will increase as pH value increases. There was positive correlation between Zeta potential and EPS, with correlation coefficient R2＞0. 97; pH was a better operation parameter than EPS to indicate the sludge properties.关键词
