Description

A kind of improvement sewage disposal system
Technical field
The utility model discloses a kind of improvement sewage disposal system, belongs to technical field of sewage.
Background technique
Oxidation ditch is a kind of end to end recycle stream aeration irrigation canals and ditches in sewage disposal system, and aeration tank is at closed State is a kind of modification of activated sludge process.Although oxidation ditch has denitrogenation dephosphorizing high-efficient, energy consumption is few, is convenient for automation control The advantages that, but when the carbohydrate in waste water is excessively high, microbial load crosses a large amount of viscous polysaccharides of hypersecretion, a large amount of water are attached In Sludge Surface, Yi Yinqi sludge bulking and der Pilz growth.The amount of grease in sewage or micro-bubble are without complete simultaneously It handles and is enriched in Sludge Surface or hole entirely, be oxygenated and stir by aeration plate, generate a large amount of foams, carry sludge rising, If excluding not in time, offscum can hinder water flow fltting speed and influence gas explosion effect, finally influence effluent quality.China is practical new Type patent 201620924168.6 discloses a kind of device that buoyant foam is handled by sprinkling anti-foaming agent, and such device uses Simply, it but increases the cost of sewage treatment and introduces new pollution sources.Chinese utility model patent 200620039472.9 is public It has opened through setting guide rail and filler fence, to prevent filamentous fungi suspension growth to alleviate asking for sludge bulking and foam Topic, but the device needs regularly to clear up and replace.Chinese invention patent 201710367659.4 has supplied a kind of eddy flow is broken to dissipate The oxidation ditch sewage treatment of processing is crushed the gentle bubble of enrichment grease that biochemical process generates by the broken scattered device of eddy flow, prevents Aging Mud up-floating, but broken scattered device needs periodic maintenance, equipment purchase and maintenance cost are high.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of improvement sewage disposal system, is adopted Technical solution are as follows: a kind of improvement sewage disposal system, including premixing pool, anaerobic pond, anoxic pond and aerobic tank, anaerobic pond It successively is connected to form oxidation ditch with the annular flow channel inside anoxic pond, aerobic tank, sewage premixing pool is arranged in anaerobic pond front end; It is equipped with water inlet pipe and mud return line in front of premixing pool, is equipped with agitating device in the anoxic pond;The aerobic tank include gallery, Propeller and aeration plate, the aerobic tank include four sequentially connected gallerys, and the aeration plate is placed in oxidation bottom of pond portion, described Propeller is placed in above aerobic tank;
Propeller includes water pump, water pipe and high-pressure nozzle;
Aeration plate segmentation in bottom is placed in aerobic tank water channel bottom;
Propeller is corresponding with aeration plate in aerobic tank respectively, above aerobic tank water stream channel;
The aeration plate is sequentially connected detachable snorkel and air blower.
The utility model has the following beneficial effects:
The present invention provides a kind of improved sewage disposal systems, and high-pressure nozzle is arranged in oxidation ditch, by taking out with dirty Offscum in water treatment system in the sewage driving oxidation ditch of itself passes through aeration zone.The improvement sewage disposal system has structure Simply, easy to maintain, operating cost is low, advantage without secondary pollution.
Detailed description of the invention:
Fig. 1 the utility model structure schematic top plan view.
Appended drawing reference: 1. premixing pools, 2. anaerobic ponds, 3. anoxic ponds, 4. aerobic tanks, 5. gallerys, 6. agitating devices, 7. water inlets Pipe, 8. mud return lines, 9. water pipes, 10. high-pressure nozzles, 11. aeration plates.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to the utility model Attached drawing carries out clear, complete description to the technical solution of the utility model.
Embodiment one
A kind of improvement sewage disposal system as shown in attached 1 figure, including premixing pool 1, anaerobic pond 2, anoxic pond 3 and aerobic tank 4, anaerobic pond 2 successively is connected to form oxidation ditch with the annular flow channel inside anoxic pond 3, aerobic tank 4, and 2 front end of anaerobic pond is set Set sewage premixing pool 1;It is equipped with water inlet pipe 7 and mud return line 8 in front of premixing pool 1, is equipped with and stirs at the corner in the anoxic pond 3 Device 6 is mixed, the present embodiment kind agitating device 6 is submersible water impeller, and model JBT300 improves the drainage flow at corner, Prevent sludgd deposition;The aerobic tank 4 includes gallery 5, propeller and aeration plate 11, and the aerobic tank 4 includes four and successively connects The gallery 5 connect, the aeration plate 11 are placed in 4 bottom of aerobic tank, and the regularly arranged formation aeration zone of aeration plate 11, the present embodiment Kind aeration zone is 3, is alternatively arranged, it is 4 sections that the gallery 5 of aerobic tank 4 is divided in 3 aeration zones, along water (flow) direction, 4 sections of length Ratio are as follows: 1:2:3:2.The propeller is placed in above the aeration zone of aerobic tank 4;
Propeller includes water pump, water pipe 9 and high-pressure nozzle 10, and setting is in the corresponding position of aeration plate 11, water pump setting In in 5 sewage of gallery, the sewage in aerobic tank 4 is pumped at high-pressure nozzle by water pump by water pipe, and water flow is by high-pressure nozzle water Flat to spray, the water-drop point of water flow is located at aeration zone water surface, which concentrates and be blocked, the water flow that high-pressure nozzle sprays With very high horizontal velocity, good impetus can be played to the offscum in the region, to guarantee the offscum of aeration zone Smoothly flow out aeration zone.
