Discussion On Water Supply Engineering Of Surface Water Plant In Xuzhou

In recent years,Xuzhou is in a high-speed period of economic development,but the water supply capacity to support economic development is insufficient.So it's urgent to increase water supply.Because of the excessive exploitation of groundwater,it can no longer be used as the main water source in cities.Surface water should be taken as the main source of water supply in Xuzhou city to increase the supply of surface water and solve the problem of water shortage:By investigating the water supply environment,we find three main problems in the water supply system.First,The existing water source structure is not ideal,so we should reduce the dependence on groundwater and make greater use of surface water,Second,surface water plants are in short supply,so we should focus on the development of it.Third,with the aggravation of pollution and the complication of pollutants,we should put forward new requirements for water purification technology.The main achievements of this paper are as follows.1)Based on the analysis of the water supply environment in Xuzhou city,combined with the surface water and water resources environment in Xuzhou city,this paper forecasts the urban water demand,the urban water demand of Xuzhou is 1.45 million cubic meters per day in the near future and 1.85 million cubic meters per day in the long term.2)Through the analysis of water resources in Xuzhou City,we have determined the idea of increasing the development and utilization of Luoma Lake.Considering the urban water demand and the water supply capacity of the source area,the paper determines the water supply scale of 30 million cubic meters per day for the newly built surface water plant.3)Through the analysis of the raw water quality of Luoma Lake and the advantages and disadvantages of various treatment processes,the water purification process of the newly built surface water plant is finally determined as follows.:raw water to pre-ozone contact pool of water distribution well to mechanical mixing tank to folded plate reaction advection sedimentation tank to V-type filter to post-ozone contact cell to reduplicated activated carbon filter to clean pool to urban pipe network.4)In addition,aiming at the problems of water supply guarantee at the present stage,the paper puts forward some measures to improve the water supply guarantee ability.In addition,aiming at the problems of water supply guarantee at the present stage,the paper puts forward some measures to improve the water supply guarantee ability.The purpose of this paper is to discuss some problems in the construction of new surface water plants in Xuzhou City,to sort out the matters needing attention and construction ideas of new water supply projects,to provide some reasonable suggestions,and to improve the economic and social benefits of urban water supply projects.
