摘要
对于河网状水体的水质提升工程,无论是内部水循环还是外源补水,如何合理确定补水点的位置和规模,涉及到总体投资规模和净水的效率,都是工程的重点和难点.文章以某市高新区内河河网水环境治理工程为例,先假定总体规模,采用EPANET给水模块建立补水管网模型,选择水泵扬程和流量、分配各补水口水量,再通过SWMM建立河网的水循环模型,验证水质变化,验算循环周期;如不满足需求,再反调补水规模,通过这样的反馈系统,反复试算,即可优化补水管网和补水口的规模,得到合适的规模、流量、管径.本次使用两个简洁免费的软件模块,快速实现河网补水和水循环的优化,可以为类似工程提供有益的借鉴.
Abstract
The water quality improvement project of river network water bodies,whether it is internal water circulation or external water replenishment,how to reasonably determine the location and scale of replenishment points,involves the overall investment scale and the efficiency of water purification,which are the key and difficult points of the project.This paper combines the example of a river network water environment treatment project in a development zone of a certain city.Firstly,assuming the overall scale,an EPANET water supply module is used to establish a replenishment pipeline network model,select the pump head and flow rate,and allocate the water volume of each replenishment outlet.Then,a water cycle model of the river network is established through SWMM to verify water quality changes and calculate the cycle period.If the demand is not met,then adjust the scale of water replenishment.Through such a feedback system and repeated calculations,the scale of the water replenishment pipeline network and water inlet can be optimized,and appropriate scale,flow rate,and pipe diameter can be obtained.This time,two simple and free software modules were used to quickly achieve the optimization of river network water replenishment and water circulation,which can provide useful reference for similar projects in the future.
