Reduction of Excess Sludge Production by Uncoupling Metabolism of TCS and OSA Process

YU Xiao-yong~1,HU Qin-hai~1,YE Fen-xia~2(1.Department of Environmental Engineering,Zhejiang University,Hangzhou 310029,China;2.Institute of Chemical Engineering,Ningbo University of Technology,Ningbo 315016,China)  
To determine whether uncoupling metabolism could be used to reduce sludge production in biological wastewater treatment,the process with the addition of 3,3′,4′,5-tetrachlorosalicylanilide(TCS)which served as a metabolic uncoupler,oxic-settling-anoxic(OSA) process and OSA with TCS process were studied to investigate the reduction of excess sludge yield.The 180?d test showed that three processes reduced the excess sludge by 33.99%,25.94% and 46.90%,respectively.Comparing with control process,COD removal rates of three processes did not significantly influenced,and TN removal rates decreased.Sludge settleability was adversely influced by TCS,but improved by OSA.Meanwhile,sludge microbeam population changed after 180?d operation.These results suggested that it might be possible to apply combined TCS and OSA process to reduce the excess sludge yield.
