浮动生物床/地下渗滤系统耦合优化

The Coupling Optimization of Suspended Carrier Floating-bed/Subsurface Infiltration System

为了使浮动生物床/地下渗滤系统合理分配两段污染负荷,充分发挥两段的处理效果,以进出水的水质为约束条件,根据其费用组成建立费用函数。以某高校工程作为实例,解得结果为浮动生物床承担46%的污染负荷BOD,而不承担污染负荷TN,基建费用减少2.7%,年度运行费用减少12%。

In order to reasonably distribute pollution loads of two sections and adequately exert treatment effects for the suspended carrier floating-bed/subsurface infiltration system , this article take inlet and outlet water quality as the restraint condition and establish expense function according to its expense composition. Take the example by some university project, the solution is that the suspended carrier floating-bed undertake 46% BOD pollution loads, but does not undertake TN pollution loads. The capital construction expense of suspended carrier floating-bed/subsurface infiltration system decrease 1% and the year operating cost of it decrease 38%.
