Abstract

The utility model discloses a zero discharge system of large -scale pig farm soil, including setting up belt cleaning device and the waste fitting discharging in the colony house of pig farm, belt cleaning device is the high pressure cleaning pump, waste fitting discharging is secret blow off pipe, the underground blow off pipe loops through the pipeline and links to each other with aeration tank, filtering ponds and biogas anaerobic fermentation device, be equipped with the aeration pipe in the aeration tank, be equipped with in the filtering ponds to filter and pack, the biogas anaerobic fermentation device is high -efficient anaerobism baffling reactor, the utility model has the advantages of: not only reduce the water consumption, reduced the nitrogen content, simple structure moreover, use cost is lower, is difficult to break down, and the maintenance cost is lower.

Description

A kind of Large-scale pig farm fecal sewage Zero discharging system
Technical field
The utility model relates to a kind of feeder pig manure sewage discharge device, and specifically a kind of Large-scale pig farm fecal sewage Zero discharging system, belongs to feeder pig manure sewage discharge device field.
Background technology
In recent years, along with the raising of living standards of the people, the demand of swine products constantly increases, and has promoted the sustainable and stable development of pig-breeding industry.The development of pig-breeding industry not only facilitates the adjustment of agricultural structure, and becomes the new growth engines of growth of agricultural efficiency, increasing peasant income.But along with pig-breeding industry development, the problem of its movement environmental pollution is also very outstanding.Name is called that " a kind of Large-scale pig farm fecal sewage Zero discharging system " application number is that the Chinese utility model patent of " 201420044721.8 " discloses a kind of Large-scale pig farm fecal sewage Zero discharging system; comprise pollution emission control subsystem, energy recovery utilizes subsystem and material recycles subsystem, interconnection between described three subsystems.But, although this system reduces water consumption, decrease nitrogen content, complex structure, use cost is higher, and easily breaks down, and maintenance cost is higher.
Utility model content
In order to solve the problem, the utility model devises a kind of Large-scale pig farm fecal sewage Zero discharging system, not only reduces water consumption, decreases nitrogen content, and structure is simple, and use cost is lower, is not easy to break down, and maintenance cost is lower.
The technical solution of the utility model is:
A kind of Large-scale pig farm fecal sewage Zero discharging system, comprise and be arranged on washing unit in the colony house of pig farm and blowdown apparatus, described washing unit is high pressure cleaning pump, described blowdown apparatus is underground blow-off pipe, described underground blow-off pipe is successively by pipeline and aeration tank, filtering basin are connected with marsh gas anaerobic fermentation apparatus, aeration tube is provided with in described aeration tank, filter packing is provided with in described filtering basin, described marsh gas anaerobic fermentation apparatus is efficient anaerobic baffled reactor, structure is simple, less investment, operational management is convenient, by anaerobion, the organism in excrement dirt is changed into biogas, obtain containing nitrogen simultaneously, phosphorus, the natural pond liquid of the nutritive elements such as potassium.
Further, described filter packing is provided with upper, middle and lower three layers, is respectively quartz sand layer, manganese layer of sand and anthracite coal measure, good filtration effect.
Further, the bottom of described filtering basin is also provided with sludge pump, and is connected with spoil disposal pipeline, mud can be discharged.
Further, being connected by straining water pipe between described filtering basin and marsh gas anaerobic fermentation apparatus, removing part of contaminated water.
Further, described marsh gas anaerobic fermentation apparatus is also connected with described washing unit by pipeline, can by the superiors' clear liquid of fermentation gained, and what be used as washing equipment uses water, saves and uses water.
In addition, be also provided with excrement cleaning device in the colony house of described pig farm, described excrement cleaning device adopts dry clear excrement technique, reduce sewage quantity, reduce the Pollutant levels in sewage, reduce the cost of follow-up sewage disposal, decrease the water consumption of rinsing colony house, water consumption reduces more than 20% simultaneously.
The utility model has the advantage of: not only reduce water consumption, decrease nitrogen content, and structure is simple, use cost is lower, is not easy to break down, and maintenance cost is lower.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1; a kind of Large-scale pig farm fecal sewage Zero discharging system; comprise and be arranged on washing unit 1 in the colony house of pig farm and blowdown apparatus 2; described washing unit 1 is high pressure cleaning pump; described blowdown apparatus 2 is underground blow-off pipe; described underground blow-off pipe is connected with marsh gas anaerobic fermentation apparatus 5 with aeration tank 3, filtering basin 4 by pipeline successively; aeration tube 31 is provided with in described aeration tank 3; filter packing is provided with in described filtering basin 4; described filter packing is provided with upper, middle and lower three layers; be respectively quartz sand layer, manganese layer of sand and anthracite coal measure, good filtration effect.The bottom of described filtering basin 4 is also provided with sludge pump 41, and is connected with spoil disposal pipeline, mud can be discharged.Described marsh gas anaerobic fermentation apparatus 5 is efficient anaerobic baffled reactor, and structure is simple, less investment, operational management convenience, by anaerobion, the organism in excrement dirt is changed into biogas, obtains the natural pond liquid containing nutritive elements such as nitrogen, phosphorus, potassium simultaneously.Being connected by straining water pipe between described filtering basin 4 and marsh gas anaerobic fermentation apparatus 5, removing part of contaminated water.Described marsh gas anaerobic fermentation apparatus 5 is also connected with described washing unit 1 by pipeline, can by the superiors' clear liquid of fermentation gained, and what be used as washing equipment uses water, saves and uses water.
In addition, be also provided with excrement cleaning device in the colony house of described pig farm, described excrement cleaning device adopts dry clear excrement technique, reduce sewage quantity, reduce the Pollutant levels in sewage, reduce the cost of follow-up sewage disposal, decrease the water consumption of rinsing colony house, water consumption reduces more than 20% simultaneously.
