本文阐述了优选传统活性污泥法二沉池同曝气池统合池容的新方法。参考文献[2,3],基于二沉池的极限固体通量,对其混合液的ISV两种模式PM和EM(乘方与指数模式)提出了二沉池的无因次式面积公式。根据保证出水水质所需澄清层最小深度的要求,本文提出了二沉池的有效池容、曝气池有效池容,以及无因次统合池容的数学模式。然后,通过对该模式的偏导解析,建立了优选统合池容的数解方程。
In this paper, a new method for optimizing the capacity of a conventional secondary sludge settling tank with aeration tank pooling is proposed. References [2,3], based on the limit solid flux of the second settling tank, proposes the dimensionless formula of the secondary settling tank for the two models of the mixture’s ISV PM and EM (power and exponent mode). According to the requirement of ensuring the minimum depth of the clarified layer required for effluent water quality, this paper proposes the effective pool capacity of the secondary sedimentation tank, the effective pool capacity of the aeration tank, and the mathematical model of the non-dimensional pool capacity. Then, through the partial derivative analysis of the model, a numerical solution equation of the optimal pool capacity is established.
