Analysis On The Effect Of Water Environment Integrated Remedying Of Yubei Shuanglong Lake In Chongqing

Eutrophication becomes one of the most significant environment problem in China, N and P nutrition elements are concentrated in lakes, reservoirs and same rivers, the phenomenon of zoology pollution and water quality deterioration appears one by one, this makes water quality deterioration in many water areas zoology system of China, and which occurs tremendous influence to the demos living and social economy development, consequently the problem has attracted Chinese government's meticulous attention Because small water collection area, low water capacity and mild water exchange adjust ability of urban lakes; also urban lakes have a close relationship with ambience, it has a high risk of pollution; the phenomenon of weakness zoology environment and water body eutrophication is common.From the practice of harness and rehabing for eutrophication water body, the effect is limited to use single method, therefore integrative methods is the develop trends to and rehabbing of eutrophication water body. The rehabing characteristic of Shuanglong lake is integrative methods, controlled both out and inside pollution source, also point and whole pollution source control, and combine the integrative recovering scheme of zoology method, engineering method and management method.This article is base on inspection of water quality after carrying out integrated water environment recovering engineering to Shuanglong lake, and fully analysis function situation and actual effect of each integrative recovery method ( include: sewage cutting, oxygen supply to water body, lake manual circle, bay bank planting, plant purify bed purified, bottlom water exchange and clean water fish), also it has a scientific evaluation to the effect of Shuanglong lake integrated rehabbing, and following are the conclusions:1) Carry out the plan of rainfalls sewerage to separate pollute source, stop pollute source to let nutrimental material to the lake, and effectively controlled out pollute source, at the same time, purify the rainfalls to supply the exchange water source.2) To set a live water oxygen equipment with manual mix elimination function inside the water, in order to increase oxygen supply quantity and adjust ability, it has function of reducing primary capacity, and effective prevent and recover water from eutrophication.3 ) Lake water body manual circle is propitious to comparatively flows, and break...
