HRT及EPS对ABR中污泥性能的影响
Effects of HRT and EPS on characteristics of sludge in anaerobic baffled reactor
摘要
Abstract
The treatment of purified terephthalic acid wastewater (PTA) was conducted in an anaerobic baffled reactor (ABR). The reactor performance and the characteristics of anaerobic sludge were determined at four different hydraulic retention time (HRT). Results showed that the chemical oxygen demand (COD) removal efficiency, mixed liquor volatile suspended solid (MLVSS),the ratio of MLVSS and mixed liquor suspended solid (MLSS) ,and the maximum specific methane production activities decreased dramatically in the first compartment with HRT decreased from 40. 0 h to 25. 0 h, whereas all of them kept constant or slightly increased in the latter compartments along the flow direction. Furthermore,the production of loosely bound extracellular polymeric substances (LB-EPS) and polysaccharide positively correlated well with the maximum specific methanogenic activity (r > 0. 687) , indicating that the production of EPS was beneficial to the sludge activity of ABR. Therefore, ABR could be applied to effectively treat PTA wastewater.关键词
