Study On Water Environment Of Shuanglong-Lake After Synthesizing Treatment

Lakes and reservoirs are one of the most importamt water resouse,provide for people water conservancy and flood control, water using and water supply, energy supply, marine products, scenery appreciate, shipping improve, accept the row dirty water and weather regulate etc,and also can interferent the society and economy uneveluablely,they are indispensability priceless resource.As for this, it is very necessary to protecet water-enviroment to keep on developing quickly of society and economy.Eutrophication of water bodies has become a global and difficult problem in controlling water pollution and is one of the most important environmental problems. At present, eutrophication of water bodies is very serious in China, which is the main environmental problem of limiting economic development.ShuangLong-lake is located in the northern part of ChongQing,YuBei distrit,which has rich water resouse and is a satellite city.As a lake in urban city, ShuangLong-lake improve the city'scenery,provide people a comfort area for entertainment.But because of uncautionous development, ShuangLong-lake was polluted seariously,and decrease the limited rain Gathering area gradually.YuBei distrit have a synthetically treatment engineering on the lake:Establishe the sewage system along the shore to collecte the waste water;Arrange plant decontamination bed to make the rainwater clean;Whole cure the lake gulf and plant the shore to protect the waterbody; pure the lake's bottom, implement dredging engineering;Arrange deep water aerate and circulation equipments which can make the water flow;Put the fish fry into the lake to protecte waterbody.This research analysis and predict water quality and variety regulation of Shuanglong-lake in different position fome flat surface and virtical direction according to the continuous water monitor data of 2004.2005 after synthesizing treatment;Use the TLI evaluation method to carry on eutrication assessment in different position and water season; Analyze to predict the source nutritional pollute&put forward the rationalization suggestion to control the pollution;Study to measure ShuangLong-lake's primary production and carry on the estimating and verifying.(1) ShuangLong-lake's water quality satisfy water standard ofâ…£. Because the water circulation and various kinds of environmental factors influence overall water environment, water quality in period of normal level better than that of dry season, it...
