曝气池是运用最广泛的生物处理构筑物,曝气池空气管道的计算直接关系到曝气池的建设和运行费用。目前我国普遍采用的空气管道计算方法是两种苏联的计算方法,但这两种方法都不正确,影响了曝气池的正确设计,也影响了鼓风机的正确选择计算。因此,一个正确而又简便的计算方法的探讨,实属必要。一、苏联计算方法的分析苏联计算方法之一的计算公式如下: h=λl/d (v_0~2)/(2g)γ+∑ζ(v_0~2)/(2g)γ式中:h——计算管段阻力损失; λ——摩阻系数; l——管段长度; d——管径;
The aeration tank is the most widely used biological treatment structure. The calculation of the aeration tank air pipe is directly related to the aeration tank construction and operation costs. At present, the commonly used air pipeline calculation method in China is two kinds of Soviet Union’s calculation method, but these two methods are not correct, affecting the correct design of the aeration tank, and also affecting the correct choice of the blower. Therefore, a correct and simple calculation method is really necessary. First, the Soviet Union’s calculation method of analysis One of the Soviet Union’s calculation method is calculated as follows: h = λl / d (v_0 ~ 2) / (2g) γ + ∑ζ (v_0 ~ 2) / (2g) γ type: h- - Calculate the pipe section resistance loss; λ - Friction coefficient; l - Pipe length; d - Pipe diameter;
