The engineering design of sewage treatment plant for the Chongqing city

P. R. China is analyzed in this paper. Considering the situation of China and other projects

the characteristics of falling water reactor for the environment protection project and economy of investment is introduced ; the application and foreground of falling water aeration in the process of sewage treatment is discussed

such as Oxidation - ditch

SBR

and so on. The conclusion indicated that the falling water aeration can be designed and used as an independent aeration

and

it is an upgraded technology of sewage treatment which is adaptive for city water environment control in middle and small towns in China. The falling water aeration may reduce running cost of the sewage treatment plant

is adaptive for foothill and the mountainous areas

and reduces project investment and environments damage.
