Description
Technical field
The utility model belongs to poultry excrement and urine disposal and utilizes field, in particular to recycling system after a kind of cow dung reprocessing, more specifically, relating to a kind of is that the solid that obtains after Raw material processing reprocessing is for the system of ox bed padding liquid for crop irrigation with cow dung.
Background technology
Cow dung is as a kind of animality organic fertilizer, it is a kind of resource of preciousness, ox food consumption is large, the fecaluria of discharging every day is more than other domestic animals, an Adult Bovine, and often Fecal wastes amplitude is 28.4-48.1kg round the clock, every voided volume amplitude is round the clock 6.5-14.1kg, a large amount of cow dungs urinates not only polluted air and water source, and occupies large stretch of soil, and the treatment process of at home and abroad cow dung is at present mainly used in compost and prepares biogas.
Adopt the treatment process of compost, cow dung makes green organic manure through biochemical complete processing process, but due to cow dung quality consolidation, composition is similar to pig manure, in excrement, water content is high, and air permeability is poor, decomposes slowly, leavening temperature is low, and fertilizer efficiency is slow, therefore habit claims cow dung to be " cold manure ".
Adopt the simple treatment process preparing biogas, a large amount of cow dung to be placed in anaerobic fermentation equipment as direct and to ferment to produce a large amount of biogas, after fermentation, the treatment process of usual remaining residue is difficult to satisfactory.
For solving the problem, there is various solution at present, such as, Chinese patent literature discloses a kind of novel ox excrement and urine treating system [patent No. ZL201320634426.3], it is by manure lagoon, solid-liquid separating machine, moisture eliminator, pulverizer, methane-generating pit forms, utilize excrement dirty flushing pump that cow dung is just entered described solid-liquid separating machine by feed line and carry out solid-liquid separation, isolated solid-state cow dung is just exported by the discharge port of solid-liquid separating machine, enter moisture eliminator and carry out drying treatment, dried cow dung is just processed into ox bed padding through crushing system, isolated liquid enters the methane-generating pit being located at underground by parting liquid output tube.
The isolated liquid of technique scheme achieves zero release, can not to environment, but there are at least three point defects in it: 1, not high to the utilization ratio of ight soil, do not carry out effective anaerobically fermenting flow process and only utilize for the biogas of natural pond liquid generation, therefore the biogas produced is very limited, particularly the utilization of the biogas produced is short of especially, can not form the recycling system of a circulation, the biogas namely utilizing ight soil self to produce is supplied in the heat drying of solid-state ight soil; 2, due to biogas from anaerobic ferment devices output time, particularly when middle temperature or thermophilic fermentation, carry a large amount of H
2s, owing to also having a large amount of water vapor to exist in biogas, the H in water and biogas
2s acting in conjunction, accelerates the Corrosion blockage of metallic conduit, valve and under meter.In addition, H
2sO is generated after S burning
2,be combined into sulfurous acid with the water vapour in products of combustion, make the metallic surface of equipment produce corrosion, and the pollution to atmospheric environment can be caused, affect HUMAN HEALTH.Therefore, before use biogas, H wherein must be removed
2s; 3, the natural pond liquid fermentation in methane-generating pit utilizes one with natural pond liquid, carries the biogas of quite a few, because these biogas do not carry out environmental protection process thus can produce serious irritating smell and have pollution to environment when needing natural pond liquid to irrigate in the liquid of natural pond.In sum, therefore this case gives birth to.
Utility model content
