Three Dimensional Hydraulic Simulation Analysis of a Secondary Water Supply Pool in a Certain Residential Area
As an important part of urban residential water supply,the rationality of secondary water supply design and subsequent operation and maintenance management have a significant impact on the water quality of the faucet.By using a three-dimensional hydraulic model to establish a mathematical model of the water tank,the change process of total chlorine in water age and the proportion of dead water zone are analyzed,in order to determine the optimal plan and provide suggestions and basis for later renovation.This article selects three time periods for simulation,and the model shows that the overall water quality is good in the first time period,with a total chlorine concentration of around 0.4 mg/L,and the mixing effect is relatively rapid in the horizontal direction.At the beginning of the second time period,the water quality in the pool was good,but as the inflow of water decreased,the total chlorine concentration in the pool gradually decreased over time.However,overall,it could still be maintained at around 0.3 mg/L.During the third time period,the total chlorine concentration in the pool continuously decreased,and the average total chlorine concentration was only 0.22 mg/L.
