Description
Technical field
The present invention relates to a kind of system and method for pig raising, are suitable for mountainous region large-scale ecological more particularly to one kind and raise pigs
System and method.
Background technique
Single household's pig production for thousands of years, pig house is very simple and crude, fencelessness, and Around the house builds pigsty, house
Lian She, family connect family, field continuous show, are far from being and enclosed breeding is isolated, and the pig house winter is warming, summer not sunstroke prevention, and air is dirty.Pig house
Excrement and sewage arbitrarily discharge, and cannot get harmless treatment for a long time, and feeding environment is caused seriously to pollute.Summer high temperature is moist, mosquito,
The hematophaguses such as fly and muroid are spread unchecked, and various pathogenic microorganisms are propagated, and cause the generation and prevalence of epidemic disease.According to surveying and determination, 1 pig year
Fecaluria about 2t is produced, if discharge outward, the day quantity of wastewater effluent about 30kg of 1 pig after being rinsed with water daily.It is total according to national environmental protection
Office's investigation, the annual feces of livestock and poultry yield in China is about 1,900,000,000 t, is 2.4 times of industrial solid gurry.In animal excrements,
In addition to polluting the environment containing nitrogen compound, phosphorus, calcium, soluble N-free object and drug etc., 100 can be also carried in waste
Various bacteria and virus cause the pollution of air, water source and soil.Have in 20 seriously polluted cities in the world 16 in
State, China have 60% or more river and lake to be polluted by chemical substance, trade waste and Toxic, and wherein aquaculture is dirty
Contaminating environment is one of its root, this is the significant problem that should not ignore, when these natural ecological environments are by destroying,
It will can seriously threaten the safety of livestock products and the health of the mankind.
Ecologically raising pigs are developed based on aquaculture, using the scientific disposal to pig excrements, and agriculture and animal husbandry knot is carried out
Close, accomplish scientific utilization, mutually promotion, low investment, high production, of low pollution benign cycle ecologically raising pigs system engineering.It relates to
And arrive the subjects such as swine science, animal nutrition, engine hygiene, biology and soil fertilizer science.It is scale, it is intensive support
Pig develops to another bright spot of certain phase, is pig breeding industry sustainable development, ensures the effective way of livestock product safety.And show
Some ecologically raising pigs systems only focus on the Ecological Disposal of pig excrements mostly, and currently used to sick dead pig covered with sawdust
The method of disease, the method need that then a water need to be poured every several days on surface on surface.If moisture is too low to will lead to resolution ratio
Low, temperature is low, causes finally to handle incomplete.This method had both caused the waste of sawdust and water, while being also unsatisfactory for ecological ring
The requirement of guarantor.
Summary of the invention
One kind is provided the purpose of the present invention is to solve the above problem and is able to achieve pig excrements scientific disposal, biogas hair
The system for being suitable for the pig raising of mountainous region large-scale ecological of electricity and sick dead pig Ecological Disposal.

The secondary use of object.The muck solid of pig excrements is handled for sick dead pig, at this sick dead pig treatment technology and existing sick dead pig
Manage process ration: sick dead pig processing at present is that sick dead pig is covered with sawdust, and a water then need to be poured every several days on surface.If
The too low resolution ratio that will lead to of moisture is low, and temperature is low, causes finally to handle incomplete.In terms of sawdust, according to the sawdust market price
It calculates, the sick dead pig for handling 30kg or so needs the cost of sawdust and tap water at 40 yuan or so.And the method for the present invention, it adopts
Sick dead pig is handled with the solid manure of live pig, it, can because the live pig excrement humidity after processed is just between 40%~60%
To reach the humidity standard for decomposing heap, so the later period eliminates the working link of watering.It is again sharp to pig manure up to standard after processing
With also reducing aquaculture cost.And reduces many working links in entire treatment process, reduce aquaculture cost.
