摘要 设计一种基于二段处理方法的高浓度COD消解数学模型和装置模型,数学模型包括反馈型A段处理方法和常规型B段处理方法。利用新型处理模型设计处理装置,能够准确模拟高负荷好氧型COD消解反应池的工作过程。实验利用污水处理厂一年的测量数据进行模型验证,计算污水COD的吸收效率,并验证新模型应用于静态环境和动态环境的可行性和有效性。结果表明,新型二段处理方法能够同时测量污泥滞留时间(SRT)和污水沉降效率(SSE),达到集总估计反应池效率和沉降器效率的目的。 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.
