摘　　要：由于城市用户产生的污水量往往会随时间发生变化,所以通过合理调度进行“削峰平谷”,充分利用污水处理厂的处理能力就显得非常有必要了。因此,对城市管网排污能力的优化设计进行了初步研究,建立了污水管网网状结构的数学模型,在管线之间设置了污水转运泵,对污水量进行了合理地调度。在分析排污能力参数优化设计中,提出了一种惯性权重自适应粒子群优化算法用于分析计算,并通过相似系数调节惯性权重,引导粒子更好地进行寻优,取得了比较好的优化效果,这对于污水系统的优化设计与高效运行具有十分重要的意义。As the amount of sewage produced by urban users often changes with time,it is very necessary to reason ably dispatch“peak cutting and valley leveling”to make full use of sewage treatment plants’treatment capacity.Therefore,the optimization design of the sewage discharge capacity is preliminarily studied,the mathematical model of the-network structure is established,and the sewage transfer pump is set between the pipelines to reasonably dispatch sewage volume.During the optimization design,a particle swarm optimization(PSO)algorithm based on adaptively inertia weight is proposed to analyze and calculate.The inertia weight is adjusted by the similarity coefficient to guide the particles to better optimize.Better optimization effect has been achieved.It is of great significance for the optimization design and efficient operation of sewage system.
