Description
Technical field
The present invention relates to field of environmental engineering, and in particular to one kind improvement energy-conservation AAO treatment method for rural sewage.
Background technology
One of the reason for domestic sewage in rural areas problem turns into aggravation agricultural pollution in recent years, 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 is arbitrarily discharged, 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 optimization to the development of society for the energy.
Most of domestic sewage in rural areas needs to follow efficient, economic, energy-conservation, easy-to-use principle.Present situation majority is used
AAO 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 multiple
It is miscellaneous.In small-scale sewage disposal（AA0 techniques）Main operating cost is consumption i.e. electric energy, to account for the half of whole operating costs very
Extremely 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（AA0 techniques）Total power consumption of middle pump（On a small scale
Refer to day output in 50-1000m3In/d, similarly hereinafter）, it is that society economizes on resources, while the cost of whole flow process is also reduced, it is right
Improving for small-scale sewage disposal system has more great meaning with promoting.
The content of the invention
It is an object of the invention to the above-mentioned drawback for prior art, there is provided one kind improvement energy-conservation AAO lives in the countryside are dirty
Method for treating water.
Concretely comprise the following steps：
First, an improvement energy-conservation AAO rural domestic sewage treating device, including wastewater influent pipe network, the lattice being sequentially connected are set up
Grid, regulating reservoir, anaerobic pond, elevator pump, anoxic pond, Aerobic Pond, air blower, oxygen-containing mixed liquor distributing trough, sedimentation basin, outlet pipe,

Mouthful.
2nd, sewage collecting pipe network is laid in units of natural village, grid is provided with sewage inlet, the sewage self-flowing after retention
To sewage regulating reservoir, sewage flow by gravity enters anaerobic pond front end after regulating reservoir degraded and sedimentation, and anaerobic pond end sets elevator pump,
Sewage and returned sludge, the oxygen-containing mixed liquor after Aerobic Process for Treatment from the gravity flow backflow of oxygen-containing mixed liquor distributing trough（Nitrification liquid）Three
Person together, anoxic pond is promoted to by elevator pump, and gravity flow afterwards enters Aerobic Pond, and Aerobic Pond end sets oxygen-containing mixed liquor distribution
Groove, oxygen-containing mixed liquor overflows to oxygen-containing mixed liquor distributing trough by triangular-notch weir, and the distributing trough is divided into two parts by dividing plate, a part
The water sucking mouth of anaerobic pond end elevator pump is flowed into by one end gravity of oxygen-containing mixed liquor distributing trough, another part is by oxygen-containing mixing
The other end gravity of liquid distributing trough flows into sedimentation basin, and the water gravity flow after processing enters sedimentation basin, and returned sludge is by sludge reflux pump
Anaerobic pond top is delivered to, the regular flow by gravity of excess sludge drains into mud storage pool, and clear water is by sedimentation basin outlet gravity flow discharge.
Grid and oil removal net are provided with the grid, the thick suspension in sewage can be retained.
The regulating reservoir plays the role of homogeneous and measured and setting pot；Due to rural sewage treatment small scale, situation of change is big,
The residence time of regulating reservoir takes 8-12 hours, with regulating water quality and water.
The ground level of the grid, regulating reservoir and anaerobic pond is less than the anoxic pond connected below, Aerobic Pond, sedimentation basin.
The grid is to regulating reservoir, regulating reservoir to anaerobic pond, and anoxic pond to Aerobic Pond and Aerobic Pond water outlet are using weight
Power is flow automatically.
The anaerobic pond receives raw sewage and returned sludge, realizes the function of anaerobic phosphorus release.

Oxygen inhales phosphorus, nitrification function.
The Aerobic Pond end sets oxygen-containing mixed liquor distributing trough, and the oxygen-containing mixed liquor of Aerobic Pond is overflowed to by triangular-notch weir
Oxygen-containing mixed liquor distributing trough, the distributing trough is divided into two parts, a part of one end gravity by oxygen-containing mixed liquor distributing trough by dividing plate
The water sucking mouth of anaerobic pond end elevator pump is flowed into, the part is the mixed-liquor return amount in AAO techniques, and its median septum is to move
Dynamic, to control mixed-liquor return amount；Another part flows into sedimentation basin by the other end gravity of oxygen-containing mixed liquor distributing trough.
The sedimentation basin realizes mud-water separation, provided with mud return line, supernatant outlet pipe and mud discharging pipe, and clear water is certainly
Stream discharge, sludge is pumped to anaerobic pond top by sludge reflux；The regular flow by gravity of excess sludge drains into mud storage pool, periodically takes away
Disposal.
The beneficial effects of the invention are as follows：
（1）By adjusting the height of elevator pump position on stream and anaerobic pond, oxygen-containing mixed-liquor return pump is eliminated, not shadow
AAO is rung in technologic function（Synchronously realize organics removal and denitrogenation dephosphorizing）, processing water outlet is reached discharge standard；
（2）A pump, streamlining management can be reduced in management；
（3）It is limited to rural sewage treatment small scale simultaneously, requires pump hoisting depth（Lift）Small the characteristics of, it is difficult to which it is suitable to choose
Pump（Find by inquiry, low discharge low lift sewage pump is less）, the characteristics of there is high energy consumption, improvement energy-conservation AAO process operations
Mode increases lifting pump discharge, and pump type selecting tends to be reasonable, can save energy consumption, reduces operating cost.
