Description
Technical field
The utility model relates to waste disposal plant, especially focuses on for Small Town Wastewater.
Background technology
Along with samll cities and towns and township and village enterprises develop rapidly, the continuous increase of the size of population, the town sewage quantity discharged also constantly increases, yet because cities and towns are paid little attention to construction of environmental protection, cause infrastructure construction to lag far behind the development of city-building, lack necessary sewage collection system and sewage treatment facility, the random discharging of sewage, brought impact not only for people's life, also destroyed simultaneously the ecotope of samll cities and towns self, cause the severe contamination of water body, become the important source of pollution of regional water surrounding.Simultaneously, because samll cities and towns are close to the rural area, livestock and poultry cultivation, the pollution of area source such as aquaculture, agricultural chemicals and chemical fertilizer are also very serious, all samll cities and towns' drinking water safety and resident's living environment constituted a serious threat, and restricted Economic development and Town Sustainable Development.Samll cities and towns' proportion in the sum of cities and towns is large, and is decentralized, is a new strategic objective after the waste water control of big and medium-sized cities.If only pay attention to the construction of big or middle city sewage treatment works, quantity is many, the waste water control of widespread samll cities and towns and ignore, and its result must be that the pollution of waterhead control of samll cities and towns can not reach re-set target.According to relevant report, estimate that the sanitary sewage of China more than 70% will be from cities and towns and residential quarter from now on.The samll cities and towns of the whole nation more than 95% all do not build sewage work at present, and Drainage System Construction is imperfection also, and small town sewage processing rate less than 10%, water pollution problems have seriously restricted the progress of society of samll cities and towns and the development of industrial or agricultural.
Because the area of samll cities and towns is less, and the population of samll cities and towns is few, the resident living rule is close, causes the daily variation system of Small Town Wastewater larger.During population in small towns forms simultaneously, quite a few is people in the countryside.Because these populations have stronger unstable and mobility, they might need to have greatly changed with the season of agriculture production.Therefore, the water yield of Small Town Wastewater has the characteristics of vary within wide limits.Simultaneously, China township and village enterprises is because economic capability is limited, in its industrial production evolution, selected mostly that production technique is simple, scientific and technological content is low, with serious pollution industry.The original production technique in big and medium-sized cities falls behind, pollutes the also trend of oriented samll cities and towns transfer of larger industrial enterprise on the other hand, due to the restriction that is subject to the Local Society economic condition, most samll cities and towns there is no sewage work, many unprocessed environment waters that enter nearby of Small Town Wastewater, serious pollution of water environment, and the structure of the Sewage treatment systems of prior art is disperseed, takes up room large, be not suitable for the Small Town Wastewater small scale, complicated component, fluctuation is large, the characteristics that concentration of suspension is higher.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the utility model provides a kind of small town sewage integrated treatment unit, and this device construction is simple, and integral body of one-tenth capable of being combined has reduced capital cost to a great extent.
The problem that exists for solving above-mentioned prior art, the technical scheme that the utility model is taked is: the small town sewage integrated treatment unit, comprise anaerobic pond, anoxic pond, Aerobic Pond and settling tank, each adjacent bottom, pond is provided with passage, convenient circulation, it is characterized in that: described anoxic pond and Aerobic Pond are tridimensional structures, the centre separates with dividing plate, for the place of land used anxiety, save floor space like this; Described anoxic pond is provided with thruster, and described Aerobic Pond is provided with water surface plug-flow type aeration machine rotor.
Described passage is aperture or pipeline, is used for sewage flow.
Aerobic Pond uses water surface plug-flow type aeration machine rotor, absorption air and water are mixed into vaporific bubble from air, evenly soluble in water and play the aeration effect, it can carry out high efficient aeration to sewage, both improved the dissolved oxygen in the sewage disposal, removed again most BOD, also alternative gas blower oxygen supply simultaneously makes more than coefficient of oxygen utilization in sewage can reach 20-25%.Aerator mainly is comprised of special-duty electric motor, impeller, induction chamber, air suction pipe, privacy protection switch etc.; high speed rotating after impeller is driven by special-duty electric motor; make induction chamber produce the vacuum low-pressure district; air is under the effect of barometric point; be pressed into induction chamber through air suction pipe, at last by in the powerful input of impeller water.The high density mixed synthetic vaporific bubble of air and water makes oxygen be dissolved in the water fully and be evenly distributed, and satisfies oxygen supply and the mix and blend demand of water treatment, and aerator is simple in structure, volume is light and handy, associate member is few, and is stable, do not need professional's maintenance management.
Described settling tank is provided with sludge reflux pump, and described sludge reflux pump connects the return flow line and anaerobic pond joins.
Described settling tank is inclined-plate clarifying basin, adopts the sloping plate deposition mode, can effectively reduce floor space, is conducive to simultaneously the sedimentation of mud.
A described settling tank bottom side relative to sludge reflux pump also is provided with the slope, facilitates sludge settling at the sludge reflux pump side.
Described anaerobic pond upper end is provided with water inlet pipe, and described settling tank upper end is provided with can regulate effluent weir, and the lower end is provided with shore pipe and mud valve, can regularly carry out spoil disposal.
Described anaerobic pond, anoxic pond, Aerobic Pond and settling tank all adopt steel construction.
Described integrated treatment unit adopts fixed bridge or floating to install, and without special basic requirement, is fit to the relatively poor situation of samll cities and towns' Infrastructure.
When the pond body degree of depth is excessive, can by adjusting the setting angle of surperficial plug-flow type aeration machine rotor, satisfy deep layer oxygen supply demand.
the utility model is mainly for small town sewage, can effectively remove organism, total nitrogen and phosphorus, its working process is: after sewage enters anaerobic pond by water inlet pipe, enter again anoxic pond by foot passage, by water surface plug-flow type aeration machine rotor, make sewage form circulation between aerobic and anaerobism, thereby reach anaerobism, anoxic, aerobic treatment process, can reach best effect to removal of pollutants, in anoxic pond, impeller is to use during deposition in anoxic pond, sewage can be by the impeller plug-flow after out from anaerobic pond, carry out effluent cycle thoroughly, through entering inclined-plate clarifying basin from foot passage after circulation after a while, carry out sludge settling, can regulate effluent weir through top through the water after sedimentation flows out, the mud of bottom sedimentation can be back to anaerobic pond through the return flow line by sludge reflux pump, the mud that gathers can regularly be got rid of by shore pipe.
