Research On South Lake Water Pollution Controlling Project

In order to solve the urgent condition of South Lake water pollution ,theauthor studied the water problem associa ted with the work experience after lotsof investigation and theriotical analysis,she also illustrated a series of content ofimproving the water-quality, setting up truck intercept sewer, increasing volumeof South Lake, as well as the method of water treatment..South Lake Park was built in 1937,it was first designed and pla nned by aJapanese designer and became a beautiful scenery of changchun city after thewater being sluice by bam. Now the South Lake lost its usua l visa geexperiencing more tha n half of a century like an old men. We should beresponsible and manage to renew the South Lake which was named as"OxygenBar". Aim at changing the old look and making it to be used as an idea lenterta inment place for the citizen ,we must try our best to make her as animportant foundamentia l facility in urban construction so that to promote thedevelopment both of socia l substance and spirit civiliza tion.This paper focus on the improvement mesures of South Lake waterpollution and supplement of water volume. The measures includes biologica lmethod, to fish out the sulla ge from the bottom of the lake ; to build an sma lltreatment pla nt ,and to intercept the sewage water nearby. the supplement ofwater will rely on the increase of natural storm and supply fresh water. Theauthor begin with water volume and quality, then analysis the reason for recentand compare with scientific and feasibility of severa l measurements so that toselect an completed scheme for supplement of water. In the scheme , raifallwater calculation ,selection of water source ,water pla nt treatment technics werediscussed in detail. So the conclusion is:If 20 thousa nd cubic fresh water wasimpoured to South lake everyday,then we can ensure the full water volume of thelake,also the water can fluid and the purification ability will be increased ,whichprovide a favorable environment for the water-pla nt and will funded a basis forSouth Lake prevention .The treatment process was composed of reaction facilities,sed imentationfacilities and filtration facilities ,while the accessoria l engineering wascomposed of pure water tank,water pump station and water transmissionpipeline. equipment.Socia l and economic benefit analysis were also presented in this article .
