压力环境下活性污泥的耐盐驯化过程
Acclimation process of salt-tolerant activated sludge under pressurized condition
摘要
Abstract
The acclimation process of salt-tolerant activated sludge with a gradual increase in salt concentration was studied by pressurized-atmospheric comparative experiments.The aim was to investigate the effect of a pressure environment of 0.3 MPa on the degradation of organic matter,the dehydrogenase activity and the extracellular polymeric substances (EPS) of sludge during the salt domestication process of activated sludge.The results showed that after the salt domestication of activated sludge,the removal rate of organics could increase to more than 75％ with a 5％ salt concentration.The removal rate of organics and the dehydrogenase activity of sludge in the pressurized reactor were higher than that of the atmospheric reactor.Moreover,the EPS of the activated sludge were stable during the salt domestication process.The content of EPS of the pressurized activated sludge was consistently lower than that of the atmosphere sludge,which may be an important reason for the in-situ sludge reduction ability of the pressurized activated sludge process.关键词
