Although the four-in-one sewage treatment equipment (ZL201420422110.2, ZL201721913979.7) with the traditional structure can better overcome the defects of more equipment, large occupied area, high energy consumption and failure rate, troublesome maintenance and the like of the sewage treatment equipment of the oxidation ditch; however, the mixed liquid in the anaerobic zone (a mixture of the sewage just entering the equipment and the return water after aeration treatment) enters the anoxic zone through the liquid extracting pipe, so that the anaerobic zone has the defects of small flow, low efficiency, easy blockage of a gas channel, troublesome installation and maintenance and the like. In addition, the sewage in the anaerobic zone is greatly impacted and stirred by the return water, so that sludge is easily splashed, and the treatment effect is influenced. Thirdly, the four-in-one sewage treatment equipment with the traditional structure also has the defects of uneven aeration pressure, slow response speed and the like.
Disclosure of Invention
To the above-mentioned defect that exists among the prior art, the utility model aims at providing a promote the flow big, efficient, the difficult four unification sewage treatment device of annular air-lift passageway that blocks up of air-lift passageway.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the device comprises a funnel-shaped outer cylinder fixed in a treatment tank, a water retaining sleeve fixed in the outer cylinder, a clear water weir positioned between the water retaining sleeve and the outer cylinder, an inner cylinder which is in a horn-shaped structure and fixed in the water retaining sleeve, an inclined tube filler component fixed between the inner cylinder and the water retaining sleeve, a pore plate fixed between the treatment tank and the outer cylinder and used for dividing the interior of the treatment tank into an aerobic zone and an anoxic zone from top to bottom, and an air stripping device positioned below the pore plate and used for communicating the anoxic zone with the outer cylinder; the air stripping device consists of an inverted cone ring sleeve fixed on the periphery of the bottom of the outer cylinder and a first annular microporous aeration pipe positioned between the inverted cone ring sleeve and the outer cylinder, and a second annular microporous aeration pipe is arranged in the anoxic zone; the first annular microporous aeration pipe and the second annular microporous aeration pipe are respectively connected with the air inlet main pipe.
A circular water baffle fixed between the outer cylinder and the inner cylinder is arranged below the inclined tube filler; the air inlet main pipe is provided with an air storage bottle.
Compared with the prior art, the utility model adopts the technical proposal, and replaces the liquid extracting pipe with the inverted cone ring sleeve and replaces the gas pipe with the annular aeration pipe on the basis of the original structure, thereby not only effectively increasing the sewage lifting amount and improving the efficiency, but also avoiding the defect that the liquid extracting pipe is easy to be blocked; meanwhile, the defect that the installation and maintenance of the air lifting channel in each direction of the traditional structure are difficult is also avoided. In addition, the water baffle is additionally arranged below the inclined tube filler, so that impact stirring of return water on sewage in the anaerobic zone can be effectively relieved. Thirdly, because the gas storage bottle is added on the air inlet main pipe, the aeration pressure is ensured to be uniform, and the aeration response speed is improved.

Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, a funnel-shaped outer cylinder 5 is fixed on the treatment tank 7, a water blocking sleeve 2 is fixed on the inner wall of the outer cylinder, and an annular clear water weir 1 is formed between the water blocking sleeve and the inner wall of the outer cylinder. A trumpet-shaped inner cylinder 3 is fixed in the outer cylinder 5, and the lower part of the inner cylinder and the lower part of the outer cylinder 5 form an anaerobic zone 16 with a large upper part and a small lower part; the wall of the inner cylinder 3 is provided with a water outlet 23 which communicates the interior thereof with the anaerobic zone 16. An inclined tube packing component 4 is fixed between the outer cylinder 5 and the water retaining sleeve 2.
A pore plate 18 which divides the interior of the treatment tank into an aerobic zone 19 and an anoxic zone 11 from top to bottom is fixed between the treatment tank 7 and the outer cylinder 5; the outer cylinder 5 is provided with water through holes 21 for communicating the aerobic zone 19 with a return channel (not shown in the figure: the annular area between the inner wall of the outer cylinder 5 and the inner wall of the water retaining sleeve 2), and an air stripping device for communicating the anoxic zone 11 with the outer cylinder 5 is arranged below the pore plate 18. The air stripping device is composed of an inverted cone ring sleeve 13 fixed on the periphery of the bottom of the outer cylinder 5 and a first annular microporous aeration pipe 14 positioned between the inverted cone ring sleeve and the outer cylinder 5, and the first annular microporous aeration pipe is communicated with the air inlet header pipe 6 through a first air inlet pipe 10. The area between the outer cylinder 5 and the reverse taper ring 13 forms an annular gas channel 17 which connects the anaerobic zone 16 with the anoxic zone 11. And a second annular microporous aeration pipe 12 fixed in the anoxic zone 11 is arranged at the periphery of the inverted cone ring sleeve 13 and is communicated with the air inlet manifold 6 through a second air inlet pipe 20.
In order to avoid the impact disturbance of the return water in the return channel to the sewage in the anaerobic zone 16, an annular water baffle plate 22 fixed between the outer cylinder 5 and the inner cylinder 3 is arranged below the inclined tube filler 4.
In order to ensure the uniform aeration pressure and improve the aeration response speed, the air storage bottle 9 is arranged on the air inlet main pipe 6. For convenience of use, a control valve 8 is installed at the outlet end of the gas cylinder 9.
In order to facilitate the removal of sludge, a sewage discharge zone 15 is provided below the inner drum 3, communicating with an anaerobic zone 16, which sewage discharge zone communicates with the outside via a pipe (not shown in the figure).
The working principle is as follows: sewage in the inner cylinder 3 enters the anaerobic zone 16 through the water outlet hole 23, then enters the anoxic zone 11 through the gas channel 17, overflows the pore plate 18 after aeration treatment, rises to the aerobic zone 19, and enters the backflow channel through the water hole 21; the return water slowly settles under the action of the water baffle 22 and forms a mixed liquor with the sewage in the anaerobic zone 16. The upper part of the mixed liquid has smaller specific gravity, so that the mixed liquid can be filtered through the inclined tube packing component 4 to form clear water and enter the clear water weir 1 for discharge; the lower part of the mixed liquid is settled in the anaerobic zone 16 due to the larger specific gravity and enters the anoxic zone 11 again for aeration treatment through the gas channel 17; the concentrated slurry then collects in the blowdown 15 for disposal.
