Description
Technical field
The invention belongs to pig-breeding field of environmental technology, more particularly to utilize the active carbon of pig manure preparation in breeding process
Layer material.
Background technique
Live pig is the maximum breed variety of animal husbandry, and the specific gravity that the live pig amount of delivering for sale accounts for the national always amount of delivering for sale reaches 92.06%,
China's live pig localization of production is laid out to be formed, and advantage producing region is prominent.With the increase of animal husbandry environmental protection pressure, many livestock and poultry
Field increasingly wishes that fecaluria can decompose in livestock and poultry farm with regard to carrying out consumption completely, avoids waste outlet and leak to cause environment
Harm.
Excrement, sewage, foul gas and the pollutants such as live pig corpse of dying of illness generated during pig-breeding, without nothing
Evilization processing is directly discharged into environment, will seriously pollute to generations such as water body, air, soil.
Pig breeding pollution object mainly includes organic pollution, microbial contamination, venomous injurant to the pollution of water body environment
The three classes such as pollution.1. organic pollution.The hydrocarbon that contains in pig-breeding waste especially sewage nitrogenous, phosphorous has
After not being discharged into rivers, lake natural water by the nutriment that live pig digests in machine object and feed, water body can be changed
Physics, chemistry, biocoene composition, rise water body solid suspension (SS), biochemical oxygen demand (BOD) (BOD), chemical oxygen consumption (COC) (COD)
It is high.After being more than the self-purification capacity and pollutional load of water body, water quality deterioration will lead to, the aquatile sensitive to organic pollution
Will be gradually dead, fish pond and river are gradually weakened using function, are occurred water body " eutrophication ".2. microbial contamination is primarily referred to as
Comprising after the pathogenic microorganism in pig-breeding pollutant enters water body with excrement and urine waste, water quality is polluted, is caused with water shortage,
Jeopardize human and livestock health and brings economic loss.3. venomous injurant pollution is primarily referred to as feed, additive, the antibiosis in veterinary drug
Element, minerals, forbidden amphetamine and the cleaning agent on pig farm, disinfectant etc. are discharged into pollution caused by it after water body with waste
Active carbon is most important material in wastewater treatment, is applied to absorption dimethylbenzene, dyestuff, heavy metal at present
Ion etc..Using the absorption and De contamination principle of active carbon, the best choosing of Wastewater from Pig Farm low cost circulation treatment can be used as
It selects.
In order to reduce the environmental pollution in pig-breeding, active carbon is prepared using the pig manure that live pig factory generates, for reducing
The development of efficient green aquaculture industry is realized in the pollution of pig farm exhaust gas and discharge of wastewater to environment, and the present invention provides one kind
Absorbent charcoal material.
Summary of the invention
In order to solve the above technical problems, the answering in Wastewater from Pig Farm processing the present invention provides a kind of absorbent charcoal material
With.
The present invention is achieved by the following technical programs.
The present invention provides a kind of application of active carbon layer in Wastewater from Pig Farm processing, it is characterised in that：
The waste water that pig farm is generated passes through active carbon layer,
The active carbon layer structure is the accumulation filling active carbon particle among two layers of mesh,
The accumulation mode is that the direction that active carbon particle prolongs perpendicular to net is filled in the way of layer heap product, the layer heap
Product is the multilayer that the superposition multilayer that grain diameter is gradually increased or grain diameter size are overlapped mutually.
The preparation step of the active carbon includes：
1. the swine excrement soaking fermentation 12-36h that will be collected during intensive culture；
2. adjusting dejecta moisture, addition bentonite, kaolin, clay, concave convex rod adjust stool consistency, make it easily
Grain；
3. soft grain granulation：By step, 2. treated that excrement directly uses soft grain granulation machine granulation formation,
4. being heat-treated：The above-mentioned soft particle being granulated into is subjected to heat treatment process, active carbon particle material is made；
5. sieving：4. granular materials that step is obtained obtains the active carbon particle of certain partial size by screening machine.
The net is metal mesh, plastic wire, to the supporting layer as absorbent charcoal material, and due to having centainly strong
Degree and flexibility, feature easy to process can be used as the carrier layer of wastewater and waste gas treatment device.For example, the metal mesh is
Stainless (steel) wire or wire netting, the plastic wire are carbon fibre web or plastic fiber net.
Efficiently accumulation is the key that realize poisonous and harmful heavy metallic, organic matter in effectively absorption waste water.
The particle size range of the active carbon is 0.01mm-10mm.Ulking thickness is 1-100mm.
The mode for adjusting dejecta moisture be the excrement that will have been cleaned add water or be dehydrated make dejecta moisture up to 10~
70% (weight percent).
The heat treatment process is first to air-dry 1-12h at 0-30 DEG C finally to exist then in 40-80 DEG C of heating 1-12h
120-200 DEG C of drying 1-12h is basically unchanged granule-morphology after drying.
The purpose of heat treatment is after drying pig manure particle, and wherein organic matter is gradually carbonized, and keeps the pattern of particle,
It does not crush.
80.1% is organic matter in the dry matter of pig manure, and easy decomposability organic C is 27.3%, hemicellulose and cellulose
Content is lower, and the content of crude fat and lignin is higher, than conveniently as the source of active carbon.
Contain bulk gas in pig manure after fermentation, form porous structure after granulating and drying, this is dirty for activated carbon adsorption
Aqueous medium provides good carrier；Active carbon table due to content of organic matter accounting nearly 1/3 in pig manure, after calcining drying
Area is larger, is very suitable for adsorbed gas processing.The present invention obtains pattern by prilling and completes and with certain strong
The pig manure particle of degree, by high-temperature heating, particle carbonization.The adjustable different faecal pellets of partial size can be obtained by being granulated.
The present invention has manufactured certain structural strength and suction by the stratum reticulare with some strength by efficiently accumulation mode
The active carbon layer of attached performance, the layer of charcoal not only can be adapted for administering the contaminated wastewater that farm generates, also improve live pig and support
Resource utilization during growing.
