The technical problems to be solved by the invention take following technical scheme to realize:
A kind of sewage disposal device promoting denitrification ability, it includes integrated sewage treating apparatus, at integrated sewage water Reason equipment is made of anoxic pond, aerobic tank, sedimentation basin, and sewage flow direction is successively by anoxic pond, aerobic tank, sedimentation basin, anoxic Pond, aerobic tank, precipitating bottom of pond portion are equipped with aerator, further include advanced treatment device and promotion water pump, and the advanced treating is set Standby to be made of outer cylinder, inner cylinder, water distributor, filler, outer cylinder top is surrounded by water outlet, is equipped with top cover, inner cylinder bottom at the top of outer cylinder Portion is equipped with support leg, and inner cylinder is closely put into outer cylinder, is supported by support leg, formed between the bottom plate of inner cylinder and the bottom plate of outer cylinder Cloth water chamber is uniformly provided with aperture on the bottom plate of inner cylinder, filler is packed into inner cylinder, and water distributor is downwardly into water distribution room from top cover, Water distributor bottom end closure, water distribution bottom of the tube surrounding are uniformly provided with water distributing pore, and the promotion water pump feed end connect with sedimentation basin, mentions Lift pump discharge end is connect with water distributor top.
As preferred embodiment, the filler be volcanic filling material, active carbon filler, bacterium room filler, in ceramics filling extremely Few one kind.
As preferred embodiment, the water distributing pore that the water distribution bottom of the tube surrounding is uniformly arranged, aperture 6mm.
As preferred embodiment, the inner cylinder top is equipped with lifting earhole.
The beneficial effects of the present invention are:
(1) after to precipitating bottom of pond portion aeration, improve sludge character, sedimentation basin middle and upper part water is handled by advanced treatment device Afterwards, guarantee that effluent quality is up to standard；
(2) to advanced treatment device, internal dissolved oxygen is conducive to the culture of nitrifier for drop after sedimentation basin water outlet is promoted；
(3) in advanced treatment device filler filling, be conducive to synchronous nitration and denitrification systematic cultivation, be further ensured that out Water total nitrogen is up to standard, prevents water outlet from containing mud scum；
(4) since integrated sewage treating apparatus is commercial standard product, a series of specifications and models are had according to water, it is such Promoted effluent quality mode, mainly using component be promoted water pump, advanced treatment device, filler, can according to water into Row adjustment, is easy in conjunction with integrated sewage treating apparatus, and for scrap build, repacking is simple, easy to operate, at low cost.
Detailed description of the invention
Fig. 1 is integrated sewage treating apparatus structural schematic diagram in the present invention；
Fig. 2 is advanced treatment device structural schematic diagram in the present invention.
In figure: anoxic pond 11, aerobic tank 12, sedimentation basin 13, lifting earhole 20, outer cylinder 21, inner cylinder 22, water distributor 23, out The mouth of a river 24, top cover 25, support leg 26, cloth water chamber 27, aperture 28, water distributing pore 29.
Specific embodiment
In order to be easy to understand to technical means, creative features, achievable purpose and effectiveness of the invention, below with reference to tool Body diagram, the present invention is further explained.
As shown in Figure 1 and Figure 2, a kind of sewage disposal device promoting denitrification ability, it includes that integrated sewage disposal is set Standby, integrated sewage treating apparatus is made of anoxic pond 11, aerobic tank 12, sedimentation basin 13, and sewage flow direction is successively by anoxic Pond 11, aerobic tank 12, sedimentation basin 13, anoxic pond 11, aerobic tank 12,13 bottom of sedimentation basin are equipped with aerator and (do not draw in figure It out), further include advanced treatment device and promotion water pump, advanced treatment device is by outer cylinder 21, inner cylinder 22, water distributor 23, filler 23 It constituting, 21 top of outer cylinder is surrounded by water outlet 24, and top cover 25 is equipped at the top of outer cylinder 21, and 22 bottom of inner cylinder is equipped with support leg 26, Inner cylinder 22 is closely put into outer cylinder 21, is supported by support leg 26, forms cloth between the bottom plate of inner cylinder 22 and the bottom plate of outer cylinder 21 Water chamber 27 is uniformly provided with aperture 28 on the bottom plate of inner cylinder 22, guarantees water distribution uniformity, is fitted into filler in inner cylinder 22 and (does not draw in figure Out), water distributor 23 is downwardly into cloth water chamber 27 from top cover, 23 bottom end closure of water distributor, and 23 bottom surrounding of water distributor is uniformly set There is water distributing pore 29；
It promotes water pump feed end to connect with sedimentation basin 13, promotes water pump discharge end and connect with 23 top of water distributor.
Filler is at least one of volcanic filling material, active carbon filler, bacterium room filler, ceramics filling.
Water distributor 23 uses pvc pipe, the water distributing pore 29 that 23 bottom surrounding of water distributor is uniformly arranged, aperture 6mm.Guarantee into Water uniformity.
22 top of inner cylinder is equipped with lifting earhole 20.Lifting when being convenient for changing filler.
Working principle:
Since there are dead zones for air lift spoil disposal, causes sludge that denitrification occurs in 13 bottom deposit of sedimentation basin, float up to water outlet Area influences effluent quality.Aerator is placed in 13 bottom of sedimentation basin, for example, aeration plate, stirs sludge, is improved dirty Mud settling property promotes sludge settling, reduces water outlet SS, guarantees effluent quality.In this way, 13 middle and upper part water of sedimentation basin is clean 's.Therefore, with small 13 middle and upper part water of flow enhancement water pump lifting sedimentation basin into successive depths processing equipment.
After the aeration of 13 bottom of sedimentation basin, improve sludge character, 13 middle and upper part water of sedimentation basin is by advanced treatment device After reason, guarantee that effluent quality is up to standard；Drop carries out drop water-filling, guarantees to advanced treatment device after the water outlet of sedimentation basin 13 is promoted Water inlet dissolved oxygen, is conducive to the culture of nitrifier；The filling of filler in advanced treatment device, is conducive to synchronous nitration and denitrification system System culture is further ensured that water outlet total nitrogen is up to standard, prevents water outlet from containing mud scum；After advanced treatment device, it is discharged from water outlet To wet well.Since integrated sewage treating apparatus is commercial standard product, a series of specifications and models, Ci Zhongti are had according to water The mode of effluent quality is risen, the use of component is mainly to promote water pump, advanced treatment device, filler, can be carried out according to water Adjustment, is easy in conjunction with integrated sewage treating apparatus, and for scrap build, repacking is simple, easy to operate, at low cost.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, without departing from the spirit and scope of the present invention, this hair Bright to will also have various changes and improvements, these changes and improvements are both fallen in the scope of protection of present invention.The present invention claims Protection scope is defined by the appending claims and its equivalent thereof.
