Research On Joint Regulation Of Gate Pumpbased On Water Quality Improvement In YangZhou Central City

Yangzhou is a historical and cultural city which built by the water and the rise of the water.However,due to the expansion of the city in recent years led to the destruction of local water system.Inner city river upstream due to the north of the city of Shugang watershed barrier no water supply.Along the way to withstand leakage of sewage,rain water pollution and sediment pollution.Water quality cannot be self-purification,easy to produce water black and algae breeding phenomenon.To eliminate the black body of water,improve the quality of landscape water,Yangzhou City regularly introduced ShaoBo Lake water,Implementation of water diversion project.Although a certain extent to improve the river water quality,but there are still scheduling problems with experience,scientific is not high,the pollution effect is not good and so on.This paper first describes the mechanism of gate pump dispatch,domestic and international engineering examples and the Research Progress at Home and Abroad of river network hydrodynamic,water quality mathematical model.According to the bnsic cqation and the solution method set up coupled model of one-dimensional hydrodynonic weter quality in river network of Yangzhou central city.Through the collection of water environment in YangZhou Cry and other relevant information,the one-dimensional hydrodynamic model is validated.YangZhou gate calculation of different degrees,plane distribution and variation of TN,TP,Ammons and Fermanganate Indexes in water.YangZhou gate the same opening,degradation of pollutant concentrations in different months.Research the amount of water and the quality of water joint control.Analysis of the application of ShaoBo Lake water for the increase in the amount of water resources,enhance water self-purification capacity,improve the central city water quality.In view of the shortcomings of the dispatch scheme,put forward joint control measures.The one-dimensional hydrodynamic coupling model is used to simulate the proposed scheme.Comprehensive analysis of the conditions of water quality improvement effect,Optimize the scientific and practical brake pump control program.At the same time,in order to better play the role of water conservancy projects on regional water environment improvement,environment,ecology,Combined with the current situation of water conservancy project ecology and environmental dispatch and the obstacle in practical work,make practical recommendations,Which provides a reference for solving the problem of water resources allocation and cross-regional ecological water transfer in water quality water shortage area.
