New activated sludge processes that utilize sorption as a major mechanism for organics removal are being developed to maximize energy recovery from wastewater organics, or as enhanced primary treatment technologies. To model and optimize sorption-based activated sludge processes, further knowledge about sorption of organics onto sludge is needed. This study compared primary-, anaerobic-, and ae...
A number of methods are presented to treat sewage sludge. However, the sludge treated in each treatment process has a problem of heavy metal elution. Currently, the treatment of sewage sludge through carbonization is highlighted to solve such problem. This study carried out research of optimum carbonization and activation condition and analysis of adsorption characteristics in order to treat se...
Three groups of SBR reactors A, B and C with different aeration time were set up to culture the activated sludge which has already bulked. The results showed that settling performance in reactor A changed a little, but had been significantly improved. High-throughput sequencing significant inhibitory effect on growth Thothrix, longer was, more obvious inhibition was. When is than 6h, mode can e...
Improvement of Anaerobic Sludge Digestion by Disintegration of Activated Sludge using Vacuum Process
As important constituents of activated sludge flocs, extracellular polymeric substances (EPS) play significant roles in pollutants adsorption, the formation and maintenance of microbial aggregates, and the protection of microbes from external environmental stresses. In this work, EPS in activated sludge from a municipal wastewater treatment plant (M-WWTP) with anaerobic/anoxic/oxic (A(2)/O) pro...
