Strategy Study On Aquatic Environment Total Amount Pollution Control Of Datong City

A scientific analysis on water pollution in Datong city is made in this paper. The conclusion is drawn that the CODcr is the subject of the total amount control, meanwhile an adjustment is made based on the capacity total amount control technology, While leads to a new boundary of Datong water environmental functional areas .The capacity of the water environment and the allowed drainage of CODcr of the surface water body in the four controlling function areas of the Haihe River drainage area in Datong is figured out. The result shows that the present drainage of CODcr in Datong area exceed the capacity of the water environment over 200%, and the pollution of the surface water is rather serious. thereby the odds of the pollution accidents may increase. On the base of the analysis and calculation, the task to reduce the drainage of the CODcr is allocated reasonably to the main pollution sources in this area. Moreover, 13 measures to realize the total amount control are put forward. The result of further assessment of the environmental capacity of Datong area manifests that the capacity of this city's environment is deteriorating yearly , which compares with the local GDP increment negatively. Therefore the emergency to construct a Datong environmental alarming mechanism is suggested in the Paper. The research in the paper offers the strategy to control the total amount water environmental deteriorating water crisis of Datong City, And this paper is worthy of referring to studying strategy in control water pollution in the Northern China especially in the highly polluted areas.
