The internal recycle of mixed solution and the automatic backflow of mud are realized in each functional zone of integrated apparatus under the effect of stirring impeller, be a kind of novel process of efficient economy type.

Summary of the invention

The purpose of this utility model provides the novel lateral sulcus formula novel all-in-one biological respinse wastewater treatment equipment that a kind of each functional zone subregion is obvious, can reduce operation energy consumption, minimizing floor space.

To achieve the above object, the technical solution adopted in the utility model is:

A kind of novel lateral sulcus formula integral biological reaction waste treatment unit, the periphery of base plate has the exterior wall and the annular settling tank of O type, medium position has the interior wall of O type to form anaerobic zone, form the oxygen-starved area between the dividing plate inboard of C type and the interior wall, form aerobic zone between the outside and the exterior wall, form the mixing zone between dividing plate breach and the exterior wall; Water-in is arranged at the interior wall bottom, and being positioned at oxygen-starved area one side has water outlet, and settling tank has water port; Aerobic zone is provided with aeration tube, is positioned at the aerobic zone of the same side, the inlet and the middle stirring impeller that is separately installed with of anaerobic zone of oxygen-starved area.

Be provided with anaerobic-anoxic mud circulation passage between anaerobic zone and the oxygen-starved area, circulation passage top is provided with inlet, outlet, and the bottom is provided with anoxic-anaerobism exchange mouth.Settling tank is supported built on stilts by at least three pillar stiffeners, be the window that settling tank and aerobic zone link between the pillar stiffener.Be extended with the inclined-plane that links and extend inwards with the exterior wall base plate under this settling tank one side direction, the horizontal sextant angle on this inclined-plane is 50～60 °.The settling tank bottom is the awl bucket of annular array, and the awl bucket is for falling platform-type structure, and its conical surface and horizontal plane angle are 60～75 °.

The utility model compact construction, succinct, operation is very easy with maintenance, and required labor force is few, and is easy to realize remote auto control.

Settling tank of the present utility model is installed in the device outside, lay ringwise, need not the outer second pond of building, the platform-type structure of falling of bucket is bored in the settling tank bottom, can effectively alleviate the turbulent flow influence of minimizing bottom flow to settling tank, and the while, the middle negative pressure that produces made mud can realize backflow certainly owing to bottom flow flows, floor space and working cost have been reduced, and help keeping the dissolved oxygen of water outlet, guarantee effluent quality, also can reduce the resistance of fluid flow.

Aerobic and anoxic of the present utility model, functional zone subregions such as mixing are clear and definite, and control helps finishing synchronously organic removal and biological carbon and phosphorous removal easily.At aerobic zone, mixed solution has been an oxygen condition, and the absorption of phosphorus also takes place for degradation of organic substances and ammonia nitrogen is oxidized to nitric nitrogen nitrate nitrogen and nitrite nitrogen effectively.Being anoxic condition in the oxygen-starved area, is carbon source with the organism, under the effect of denitrifying bacteria is nitrogen and removing from water with nitrate-nitrogen reduction.In the ammonification of anaerobic zone generation organonitrogen, and degradation of organic substances carries out the release of phosphorus.

The utility model is provided with anaerobic-anoxic mud circulation passage, helps improving the anaerobic zone sludge concentration, thereby has strengthened system's anti-shock loading and dephosphorization ability.

The utility model helps mixed solution repeatedly circulation between aerobic-anoxic-mixing zone, and refluxes automatically and realize the denitrogenation purpose.

Embodiment

See figures.1.and.2, the periphery of base plate 19 has the exterior wall 1 and the annular settling tank 8 of O type, medium position has the interior wall 14 of O type to form anaerobic zone, form oxygen-starved area 4 between dividing plate 5 inboards of C type and the interior wall 14, form aerobic zone 2 between the outside and the exterior wall 1, form mixing zone 15 between dividing plate 5 breach and the exterior wall 1; Water-in 16 is arranged at interior wall 14 bottoms, and being positioned at oxygen-starved area 4 one sides has water outlet 17, and settling tank 8 has water port 7; Aerobic zone 2 is provided with aeration tube 3, is positioned at the aerobic zone 2 of the same side, the inlet and the middle stirring impeller 6 that is separately installed with of anaerobic zone of oxygen-starved area 4.

Be provided with anaerobic-anoxic mud circulation passage 11 between anaerobic zone and the oxygen-starved area 4, circulation passage 11 tops are provided with inlet 10, outlet 12, and the bottom is provided with anoxic-anaerobism exchange mouth 13.

Settling tank 8 is supported built on stilts by three pillar stiffeners 18, the window that links for settling tank 8 and aerobic zone 2 between the pillar stiffener 18.Be extended with the inclined-plane 20 that links and extend inwards with base plate 19 under these settling tank 8 one side direction, the horizontal sextant angle on this inclined-plane 20 is 50～60 °.Settling tank 8 bottoms are the awl bucket 9 of annular array, and awl bucket 9 is for falling platform-type structure, and its conical surface and horizontal plane angle are 60～75 °.

Principle of work of the present utility model is: organic degraded, the ammonification of organonitrogen, the release of phosphorus take place by 16 water inlets of interior wall 14 foot water-ins in sewage in anaerobic zone, enter into oxygen-starved area 4 by water outlet 17 then.Microbial population in 4 ingress, oxygen-starved area are stirred under the promotion of impeller 6 with it carries out thorough mixing.The mixed solution part of oxygen-starved area 4 flows out the oxygen-starved area, another part flow into anaerobic-anoxic mud circulation passage 11 by the inlet 10 that is arranged on anaerobic-anoxic mud circulation passage 11 tops, deposit herein, supernatant liquor liquid flow into mixing zone 15 by the outlet 12 on top, below the inlet 13 of the higher mud of concentration by the bottom be back in the anaerobic zone in the interior wall 14.4 mixed solutions are anoxic condition in the oxygen-starved area, carry out the utilization degraded of denitrification denitrogenation and partial organic substances; Entering mixing zone 15 then mixes with mixed solution from oxygen-starved area 4, aerobic zone 2, another part enters aerobic zone 2 respectively through aerobic zone 2 inlets, the aeration tube of laying between partition wall 5 in aerobic zone 2 bottom being installed in and the exterior wall 13 carries out aeration, make mixed solution be oxygen condition, in aerobic zone 2, carry out the nitration reaction of organic matter removal, ammonia nitrogen, the absorption of phosphorus.
