Put.
Background technology
Domestic sewage in rural areas problem turns into one of the reason for aggravation agricultural pollution in recent years, and it pollutes small scale, and composition is multiple
Miscellaneous, fluctuation is big, and concentration of suspension is higher, and is restricted by Local Society economic condition.According to investigations, the whole nation is small-scale dirty
Water process does not have discharge conduit and sewage disposal system, and sewage arbitrarily discharges, and causes the pollution of serious river water and environment.But
With social development, small-scale, organized sewage load will necessarily increase, and the energy consumed can also increase therewith, such as
What reasonable arrangement makes being significant using the development optimized to society for the energy.
Most of domestic sewage in rural areas needs to follow efficient, economic, energy-conservation, easy-to-use principle.Present situation is most to be used
AO PROCESS FOR TREATMENTs, but its technique has long flow path, floor space is big, and investment and operating cost are higher, and operation operation is more complicated.
In small-scale sewage disposal（A0 techniques）Main operating cost is consumption i.e. electric energy, to account for the half of whole operating costs even more
More, the electric energy being consumed is mainly used in sewage lifting operation power charge and plug-flow and oxygenation etc..
In view of the above-mentioned problems, how research reduces small-scale sewage disposal（AO techniques）Total power consumption of middle pump（It is on a small scale
In a few days treating capacity is in 50-1000m3In/d, similarly hereinafter）, economized on resources for society, while the cost of whole flow process is also reduced, to small
Improving for scale sewage disposal system has more great meaning with promoting.
