Background technique

Pig breeding industry is one of the important industry in China's animal husbandry, with the continuous development of aquaculture, China's pig breeding industry Either all significant changes are occurring for aquaculture model, Regional Distribution or production method, production capacity.At present in pig breeding industry, row It lets out object all and is more reluctant, in the modern society for advocating sustainable development, the excreta of swinery is made full use of to generate natural pond Gas, it is used in other aspects that the biogas of generation, which can be used as energy substance, this is the important embodiment for carrying out sustainable development.

The pollution that livestock and poultry breeding industry generates mainly has three excrement, waste water, foul smell aspects, contains a large amount of cause of disease in excrement Microorganism, parasitic ovum and the mosquito multiplied can be such that cause of disease type in environment increases, and bacterium amount increases, and former germ occur and post Infested mass propagation causes the sprawling of people, animal infectious disease；Water is big and temperature is lower, and solid-liquid mixes in waste water, the change of nitrogen and phosphorus It is higher to close object organic content；Contain a large amount of hydrogen sulfide, ammonia, more than 200 kinds of alcohol, methane organic odoriferous substances in foul gas, these Gas can stimulate people and animals' respiratory tract, cause respiratory disease and livestock and poultry cultivation productivity is caused to decline.Scale animal and poultry cultivation is useless The processing of water has caused the great attention of farm's industry and relevant department at present, take a series of control measures and select it is economical, Efficient processing technique is very urgent.With the increasingly update of state sewage emission standard, standardizing high-concentration culture waste water row It is more prominent to put problem, because it is so stubborn problem in environmental protection that the improvement of breeding wastewater, which is appointed,.Due to lack it is various it is practical, The low livestock breeding wastewater processing technique at, high treating effect makes the pollution problem of scale livestock farming still fail to obtain effectively Solution.

Utility model content

The technical problem to be solved by the present invention is to provide one kind separately to handle the excrement on pig farm and urine, makes Treated excrement for producing gas, the water of purification can be recycled, and the discharge of object, effective protection are effectively avoided pollution The wastewater from pig farm processing system of environment.

In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows: a kind of wastewater from pig farm processing system, including Septic tank, conditioning tank, sand setting filtering ponds, the pond UASB, aeration tank and end-filtration pond, the septic tank pass through described in pipeline connection Conditioning tank；The conditioning tank connects the feed end of the sand setting filtering ponds by sewage pipe；The sand setting filtering ponds are " recessed " word The bottom right side of shape, the sand setting filtering ponds is equipped with water filter plate；Quartz sand layer is filled on the water filter plate；The sand setting filtering The right hand top in pond is equipped with overflow port；The overflow port connects intermediate sedimentation pond by overflow pipe；The intermediate sedimentation pond passes through Pipeline connects the pond UASB；The water outlet in the pond UASB connects the aeration tank by pipeline；The water outlet of the aeration tank End connects the water inlet end in the end-filtration pond by outlet pipe；Sludge pump is equipped in the sand setting filtering ponds；The sludge pump Separating dry space from moist space machine is connected by blow-off line；The outlet end of the separating dry space from moist space machine connects the intermediate sedimentation pond by pipeline； The solids exit end of the separating dry space from moist space machine connects fermentation vat by feeding mechanism.

Preferably, it is successively arranged activated carbon filter layer, sand filter, filter screen and life from top to bottom in the end-filtration pond Object filter membrane.

Preferably, the water outlet in the end-filtration pond connects ozonization pond by pipeline.

Preferably, the aeration tank sequentially consists of eps foam layer, haydites of book structure layer, activated carbon adsorption layer and goose Boulder bed.

Preferably, the conditioning tank is equipped with dispensing mouth.

The beneficial effects of the utility model are: the utility model passes through septic tank, conditioning tank, sand setting filtering ponds, UASB Pond, aeration tank and end-filtration pond handle respectively after can advanced treating livestock breeding wastewater, make COD, antibiotic, N, P, organic Object etc. is removed jointly, and scale processing cost is cheap；Finally, the excrement on pig farm and urine can separately be handled, is made Treated excrement for producing gas, the water of purification can be recycled, and the discharge of object, effective protection are effectively avoided pollution Environment.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of utility model wastewater from pig farm processing system.

Specific embodiment

Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other It can be combined with each other.

As shown in Figure 1, a kind of wastewater from pig farm processing system of the utility model, including the filtering of septic tank 1, conditioning tank 2, sand setting Pond 3, the pond UASB 4, aeration tank 5 and end-filtration pond 6, septic tank 1 connect conditioning tank 2 by pipeline, and conditioning tank 2 passes through sewage pipe Connect the feed end of sand setting filtering ponds 3；Sand setting filtering ponds 3 are concave, and the bottom right side of sand setting filtering ponds 3 is equipped with water filter plate 31；Quartz sand layer 32 is filled on water filter plate 31；The right hand top of sand setting filtering ponds 3 is equipped with overflow port 33；Overflow port 33 passes through Overflow pipe connects intermediate sedimentation pond 7；Intermediate sedimentation pond 7 connects the pond UASB 4 by pipeline；The water outlet in the pond UASB 4 passes through pipeline Connect aeration tank 5；The water outlet of aeration tank 5 connects the water inlet end in end-filtration pond 6 by outlet pipe, in the end-filtration pond 6 It is successively arranged activated carbon filter layer 61, sand filter 62, filter screen 63 and biological filtering membrane 64, certain the utility model from top to bottom End-filtration pond 6 structure more than one, can also be increased and decreased according to sewage situation；Sewage is carried out in order to more preferably net To change, aeration tank 5 sequentially consists of eps foam layer 51, haydites of book structure layer 52, activated carbon adsorption layer 53 and pebble layer 54, By multilayer filtrate can depth except the organic matter in decontaminated water；Sludge pump 34 is equipped in sand setting filtering ponds 3；Sludge pump 34 passes through Blow-off line connects separating dry space from moist space machine 8；The outlet end of separating dry space from moist space machine 8 connects intermediate sedimentation pond 7 by pipeline；Separating dry space from moist space machine 8 solids exit end connects fermentation vat 9 by feeding mechanism.
