Description
[technical field]
The present invention relates to technical field of sewage, a kind of specifically Small Town Wastewater treatment integrated high-efficiency low energy
Consumption novel process equipment and processing method.
[background technology]
With the fast development of social economy, China's quantity of wastewater effluent increases year by year, at " 13 " municipal sewage concentration
Reason rate target is set to 95%, but region (such as rural area, samll cities and towns, the outskirts of a town life of extension is difficult to for municipal sewage pipe network
Area etc.), wastewater treatment rate is still very low.There is more than 40000 small towns in China, and there are multiple natural villages in each small towns, all suffer from again
The problem that sewage natural is discharged and polluted.Now with the development of China, these problems are in the urgent need to address.
Most of existing sewage treatment facility in current rural area is following technique:
(1) Ecological Disposal pattern, such as ecological pond processing system, artificial wet land treating system, subsurface infiltration treatment technology, earthworm
Earthworm ecological filter etc., this kind of technique has floor space than larger, and sewage load is limited, while also being lacked by winter low temperature effect etc.
Point；
(2) traditional waste water treatment process, such as A/O, A2O, SBR, CASS, bio-contact oxidation, UBOX, this kind of technique is all
It is buried and submerged, although comparative maturity, but floor space, still than larger, while corollary equipment is relatively more, fault rate is high,
Technology controlling and process is complicated, and operation maintenance requirement is high, and investment and operating cost are also higher, is adapted to southern economy developed regions；
(3) Combining with terrain, geology, Vegetation condition, technique is combined by above-mentioned (1) and (2), this kind of technique still suffer from
Upper two kinds of shortcomings.
China's patent 201510755790.9 discloses a kind of sewage disposal system, by the anaerobic pond that is sequentially communicated, good
It is aerobic in order to air is passed through that oxygen pond and sedimentation basin realize circulation, continuous sewage disposal, but the sewage disposal system
, it is necessary to extra setting air pump and corresponding aeration tube, improve the cost of operation and the complexity of equipment in pond, it is unfavorable for
The social demand of energy-conserving and environment-protective.China's patent 201510116668.7 discloses a kind of sewage disposal system, including pre- anoxic pond,
Anaerobic pond, anoxic pond, Aerobic Pond, can be with the flexible and changeable various water quality of generally adaptation and processing requirement, but sewage is all letter
Single ground is directly entered in each processing pond by water inlet pipe, it is impossible to is made the contact that sewage is full and uniform with intracisternal material, and is needed
Make sewage be passed through successively in each processing pond to be reacted, result in the reduction for the treatment of effeciency, and to take larger area.
And with treatment scale according to 200m3/ d is counted, and the cost of investment of traditional sewage treatment process is in 4000-6000
Yuan/ton, operating cost is in 0.80-1.40 units, and investment and operating cost are higher.
Therefore, research and develop that a kind of handling process is simple, investment and operating cost are low, treatment effeciency is high, energy-conservation and operation maintenance
Simple integrated sewage treating apparatus have very important significance.
