Description

Livestock and poultry cultivation sewage disposal device

Technical field

This utility model relates to livestock and poultry cultivation technical field, is specifically related to a kind of livestock and poultry cultivation sewage disposal device.

Background technology

Sewage of farm mainly includes the high concentrated organic wastewater rich in a large amount of pathogen (escherichia coli, roundworm egg etc.), Float and ammonia-nitrogen content are big, if do not dealt carefully with, will enter Water table polluted underground water by rainwash and diafiltration. After this raw sewerage enters natural water, make solid suspension in water, Organic substance and content of microorganisms raise, change The physics of water body, chemistry and biome composition, make water quality degenerate.Sewage will pass through water possibly together with substantial amounts of pathogenic microorganism Body is diffused propagating, and endangers human and livestock health.In order to accomplish the organic knot of the three of economic benefit, social benefit and environmental benefit Close, it is necessary to its sewage is effectively administered.Along with developing rapidly of livestock and poultry breeding industry, the pollution of sewage of farm is the most increasingly Extensively with serious.Cultivation class ammonia nitrogen in waste water content is the highest, cannot ensure that ammonia nitrogen has good clearance, in addition with traditional equipment In sewage, substantial amounts of pathogenic microorganism also cannot effectively be removed, and does not reaches discharge standard.

Utility model content

This utility model is for the deficiencies in the prior art, it is provided that the livestock and poultry cultivation sewage disposal device of a kind of dependable performance, Solve traditional equipment and cannot effectively remove the problem of ammonia nitrogen and pathogenic microorganism, and discharge standard can be reached, it is achieved waste water Zero-emission.

The technical solution of the utility model is achieved in that what this livestock and poultry cultivation sewage disposal device included being sequentially communicated Grid, regulation sedimentation tank, anaerobic jar, coagulative precipitation tank, ozonization tank, adsorbent equipment and nanofiltration device, described grid front end With the defecation pipeline communication of poultry house, described nanofiltration device rear end is communicated with discharge outlet.

UASB anaerobic reactor it is provided with in described anaerobic jar.

It is filled with activated carbon in described adsorbent equipment and inhales adsorbent.

Described coagulative precipitation tank is folded plate type flocculation basin.

Described nanofiltration device includes NF membrane, housing, interior connector and end plate, described NF membrane molecular cut off 200～ 1000。

Described grid is rustless steel grid, the gap length 16～20mm of described grid.

This utility model solves defect present in background technology, has the advantages that

This livestock and poultry cultivation sewage disposal device solves traditional equipment cannot effectively remove ammonia nitrogen and pathogenic microorganism Problem, and discharge standard can be reached, it is achieved wastewater zero discharge.This utility model is anti-by being provided with efficient UASB anaerobism in anaerobic jar Answer device removing while COD, there is dephosphorization and denitrification effect, COD clearance 90%～95%, ammonia nitrogen removal frank more than 95%, Reach preferable treatment effect.After ozonization and activated carbon adsorption, absorb remaining COD and ammonia nitrogen further.Finally Can be less than 10mg/l by the COD of water outlet after nanofiltration device, ammonia nitrogen can be less than 0.1mg/L, simultaneously disease caused by infectious water pathogenic microorganism (large intestine Bacillus group, roundworm egg etc.) substantially can reach 99.9% removal, be fully achieved country discharge standard, it is achieved waste water zero-emission Put.

Accompanying drawing explanation

Fig. 1 is theory diagram of the present utility model；

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

The theory diagram of livestock and poultry cultivation sewage disposal device as shown in Figure 1, including the grid being sequentially communicated, regulation precipitation The defecation pipeline of pond, anaerobic jar, coagulative precipitation tank, ozonization tank, adsorbent equipment and nanofiltration device, grid front end and poultry house Connection, nanofiltration device rear end is communicated with discharge outlet.UASB anaerobic reactor it is provided with in anaerobic jar.Activity it is filled with in adsorbent equipment Charcoal inhales adsorbent.Coagulative precipitation tank is folded plate type flocculation basin.Nanofiltration device includes NF membrane, housing, interior connector and end plate, institute State NF membrane molecular cut off 200～1000.Grid is rustless steel grid, the gap length 16～20mm of described grid.Grid, Regulation sedimentation tank, anaerobic jar, coagulative precipitation tank, ozonization tank, adsorbent equipment and nanofiltration device

This utility model implementation process is: the aquaculture wastewater that poultry house produces first carries out solid-liquid separation process through grid, point From excrement slag solid content can be used as fertilizer or make organic composite fertilizer product, it is also possible to as fish and shrimp feedstuff；Use artificial side The foreign material that formula timing cleaning grid and screen cloth retain.Enter regulation sedimentation tank from grid waste water gravity flow out, carry out water yield tune Joint；Being fed into anaerobic jar by pumping after waste water is formulated, be provided with efficient UASB anaerobic reactor in anaerobic jar, this technique is being removed While COD, there is dephosphorization and denitrification effect, COD clearance 90%～95%, ammonia nitrogen removal frank more than 95%, reach preferable Treatment effect.Need to enter ozonization tank through the water outlet of coagulating sedimentation and carry out ozonization, that on the one hand can kill in water is each Plant causal organism, partial organic substances of on the other hand can also degrading, make COD be removed further, can in the water after ozonization Energy meeting ozone content is higher, it is therefore desirable to again through activated carbon adsorption, same activated carbon adsorption has two functions, one, suction The ozone of attached excess, two, absorbed portion Organic substance reduces COD, and therefore after ozone+activated carbon, COD can reach 80mg/L Left and right, ammonia nitrogen can reach about 10mg/L, meets the inflow requirement of nanofiltration device, and the COD of water outlet after nanofiltration device can be little In 10mg/l, ammonia nitrogen can be less than 0.1mg/L, and disease caused by infectious water pathogenic microorganism (coli-group, roundworm egg etc.) substantially can reach simultaneously To the removal of 99.9%, it is fully achieved the discharge standard of country, it is achieved wastewater zero discharge.Further according to aquaculture water quality country Standard scale, this water outlet fully meets aquaculture water quality requirement, can supply water for aquaculture, improves water resource further and utilizes Rate.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model Protection domain within.
