Background technique
As population increases, urbanization process is accelerated and industrial point source total amount control of pollution measure executes, resident living is dirty Dye will gradually replace industrial pollution as the water body first pollution factor.In urban district, high pipe network collects coverage rate, wastewater reuse approach Undoubtedly correctly selection, and in villages and small towns area, it concentrates pipe network can not be sensible, that is, allows to extend with main roads, adapter tube takes With and long-distance sewage pumping station conveying, operating cost it is all very high, take waste water to seep under nature in soil after residence before residence, excrement more The easy means for the treatment of in situ in various manure pit are stored in, environment is seriously polluted, unit cost of sewage disposal also greatly improves.Separately On the one hand, villages and small towns environmental protection is ignored for a long time, and domestic water pollution in villages and small towns is more serious, with constantly pushing away for new countryside architecture It becomes increasingly conspicuous into the problem of, villages and small towns water pollution, not only seriously affects and constrain the development of agricultural, peasant increases income and rural area Modernization, and biggish passive shadow is all produced to the development of the living environment, economy and society in vast villages and small towns area It rings, has become the important restriction factor of new countryside architecture.Existing villages and small towns sewage-treatment plant equipment manufacturing cost is expensive, handles sexual valence Than low, in villages and small towns area performance difficulty.
Therefore, those skilled in the art is dedicated to developing a kind of inexpensive, efficient, simple villages and small towns sewage treatment of maintenance Device will be used for water body supply etc., not only solve the problems, such as that villages and small towns water pollution is serious, also delay after domestic sewage of villages and small towns treatment in situ The problem of having solved shortage of water resources.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of sewage treatment dresses suitable for distributing villages and small towns sewage It sets.
In order to solve the above-mentioned technical problem, a kind of the technical solution adopted in the utility model are as follows: efficient low-consume sewage treatment Inlet and outlet are respectively set in device, including cabinet on cabinet, and anaerobic pond, aerobic is disposed in the cabinet Pond, sedimentation basin and filtering ponds;Partition is also set up in anaerobic pond and forms sludge area A and anaerobic zone, and in anaerobic zone, air lift is set The water of sludge area A is drained to anaerobic zone in sludge area A setting stripping reflux device by agitating device;The water inlet end of aerobic tank connects Logical anaerobic pond, water outlet connect sedimentation basin;One mud return line is set in the bottom of sedimentation basin, mud return line connection is aerobic The sludge area A in pond;Filtering area is set in filtering ponds and clear water zone, filtering area connect sedimentation basin, cabinet by water pipeline Water outlet be located at clear water zone.
Further, recoil water pipe and backwash tracheae is also respectively set in filtering area, recoil water pipe connects clear water zone.
Further, it is additionally provided with sludge bucket in the bottom of sedimentation basin, sludge bucket is in inversion truncated rectangular pyramids shape;In sedimentation basin Top be provided with jagged effluent weir, an overflow pipe is connected above effluent weir, overflowing liquid exports case by overflow pipe Internal portion also sets up a blow-down pipe in precipitating bottom of pond portion, and blow-down pipe stretches out outside cabinet.
Further, partition is also set up in anaerobic pond and forms multiple anoxic zones and sludge area B, and in sludge area, B is also provided with The water of sludge area B is drained to anoxic zone by stripping reflux device, and mixed liquor return pipe, the mixed liquor is arranged in the bottom of aerobic tank The end of meeting flow tube is protruded into sludge area B;Anaerobic zone connects the water inlet of cabinet, be sequentially communicated between anoxic zone and finally with it is good The connection of oxygen pond.
The beneficial effects of the present invention are:
Sewage-treatment plant of the invention reacts sewage sufficiently under the effect of air lift agitating device in anaerobic pond, through aerobic Pond aerating pipelines are oxygenated and stir, and enter sedimentation basin by aerobic tank effluent weir, the inversion in conjunction with clarifier sludge bucket is just tetragonous Platform shape, sedimentation effect reach best;The setting of overflow pipe and back-flushing structure keeps system operation simple, efficient;Gas backstreaming The setting of device and air lift agitating device enables the system to consumption and substantially reduces.Whole setting meets low cost, high energy efficiency, Yi An The villages and small towns Sewage Disposal design concept of dress, Yi Yunhang.
Detailed description of the invention
Fig. 1 is the planar structure schematic diagram of the utility model;
Fig. 2 is the schematic diagram of the section structure of Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the efficient low-consume sewage-treatment plant of the utility model, including cabinet, on cabinet respectively Water inlet 1 and water outlet 18 are set, are disposed with anaerobic pond, aerobic tank 10, sedimentation basin 14 and filtering ponds in the cabinet 14。
Partition is also set up in anaerobic pond forms independent sludge area A5, sludge area B 7, anoxic zone 6 and anaerobic zone 2, Gas stirring device 3 is arranged in anaerobic zone 2, is able to carry out sewage and stirs, sufficiently progress anaerobic reaction.In sludge area A and sludge Stripping reflux device 4 is arranged in area B, and by treated, water is drained to anaerobic zone 2 and anoxic zone 6 respectively.Anoxic zone in the present embodiment Quantity use three, be successively arranged side by side, anaerobic zone connects the water inlet of cabinet, be sequentially communicated between anoxic zone and finally with Aerobic tank connection.
10 water outlet of aerobic tank connects sedimentation basin 14, liquid can be imported sedimentation basin 14 by an effluent weir herein In, in 10 bottom of aerobic tank, setting aeration tube 11 is aerated mixed liquor.A mixed liquor is also set up in the bottom of aerobic tank Return pipe 9 connects sludge area B.Aeration tube is sufficiently aerated waste water, and plays stirring action, and aerobic reaction thoroughly carries out, Mixed liquor return pipe reflux inside aerobic tank makes concentration of wastewater keep stablizing, and system is normally and efficiently run.
It is additionally provided with sludge bucket 12 in the bottom of sedimentation basin 14, sludge bucket 12 facilitates sludge poly- in truncated rectangular pyramids shape is inverted Collection.The top of sedimentation basin 14 is provided with jagged effluent weir 21, the water that effluent weir 21 overflows is flowed into filtering ponds.Going out An overflow pipe 22 is connected above mill weir 21, overflowing liquid is exported box house by overflow pipe 22, is also set up in precipitating bottom of pond portion One blow-down pipe 13, blow-down pipe 13 stretch out outside cabinet.The sludge of deposition is imported in precipitating bottom of pond portion setting mud return line 8 Sludge area A.
