Experiment Research On Domestic Wastewater Treatment In Sequencing Batch Reactor Activated Sludge Process

The dissertation analyse the feature,mode of operation,water quality,yield of water and the kinds of proper wastewater on sequencing batch reactor(SBR).SBR is suitable for the treatment of domestic wastewater.By experiment to some factors of the impact on the strainaway rate of domestic wastewater COD,the results indicate that,the strainaway rate of COD will be over90%,when consistence of waterflooding COD is less than1750.0mg/L.The appropriate aeration time is between6(for Level2emissions standards) and8(for Level2emissions standards) hours.The average strainaway rate will be more than95%with the optimum pH range from6.5to7.5.The consistence of DO is best at6.0mg/L.The suitable organic load Ns number stands at1.6gCOD/(gMLSS·d),and that of Nv is3.6gCOD/(L·d).At the same time.3500.0gMLSS/L is the best sludge consistence.
