【Abstract】 A new mathematical model for digesting of high concentration COD is proposed in this paper. The two stage model consists of the feedback A processing stage and the traditional B processing stage. The simple device is designed for simulating the digesting reactor, which contains high load aerobic COD. New model was validated using the measured data from the sewage treatment plant in one year. The absorption efficiency of COD was calculated, to verify the feasibility and validity of our new model. The experimental results show that, firstly, this processing model can applied to the static and dynamic environment. Secondly, the sludge retention time(SRT) and the sewage settling efficiency(SSE) can be measured, simultaneously. Thirdly, the efficiency of the reactor and the efficiency of the settler can be estimated at the same time.更多还原
