Description

A kind of method of handling pig manure production fertilizer
Technical field
The present invention relates to modern livestock breeding industry, environmental pollution improvement and fertilizer field.Particularly relate to and a kind ofly be primarily aimed at China southwest and characteristics such as similar area is rainy, moist, winter temperature is on the low side, the pig manure of intensive pig production generation, the method for cleaner production fertilizer are handled in innoxious, less energy-consumption.
Background technology
Along with the raising of people's living standard, the continuous increase of population increases day by day to the requirement of meat product, and progress of science and technology makes traditional pig industry develop rapidly to the intensive pig production mode, has also brought a series of environmental problem thereupon.Around many pig farms, concentrate near the ecotopes such as land, water body and air of the dirty severe contamination of excrement of discharging, be badly in need of effectively administering.
At present, the method for administering the intensification piggery waste is a lot, and technical characterstic has nothing in common with each other, and suitable condition and range is also different.Produce in the process of fertilizer at the harmless treatment pig manure, drying and dehydrating, deodoring and disinfecting, quick composting, cut down the consumption of energy, problem such as cleaner production all do not obtain fine solution.In addition, these technology relatively are fit to the area of northern China dry and rainless, and the higher South China of winter temperature.China southwest is rainy, moist, winter temperature is on the low side, and the effect of using relevant technologies processing pig manure is relatively poor, and cost is higher, is difficult to effective application, is badly in need of the pig manure that a kind of effective processing intensification of exploitation pig farm produces, and the novel method of production fertilizer.
Summary of the invention
The objective of the invention is to, provide a kind of suitable China southwest and similar area, innoxious, less energy-consumption processing and utilizing pig manure, the method for cleaner production fertilizer.Under the condition rainy, moist, that winter temperature is on the low side, the pig manure that the intensification pig farm is produced carries out deodoring and disinfecting, quick composting, drying and dehydrating effectively, produces the organic fertilizer that is fit to arable farming.
A kind of method of handling pig manure production fertilizer of the present invention, realize successively through the following steps:
(1) gather fresh horsehit, mix with the pig manure of water content 70~75% in 1: 10 ratio of mass ratio, composting is 10 days in insulation can or fermentation vat or fermenter, gets original microbial inoculum;
(2) original microbial inoculum is mixed with the pig manure of water content 70~75% in 1: 10 ratio of mass ratio, composting is 10 days in insulation can or fermentation vat or fermenter, must produce and use fermenting agent;
(3) build the sun power Isolation warm house, material of main part uses transmittance greater than 80% hollow sunlight board, and the top is an arcuate structure, and its area is pressed: S=0.1X+300 calculates, and X is the fertilizer annual production, 1000<X<10000 ton; The common calcium sulfate of mass ratio 75% is mixed with 25% ordinary calcium carbonate, make nitrogen-protecting deodorant; In the sun power Isolation warm house, respectively add in the pig manure of water content 70~75% producing in the ratio of mass ratio 1% with fermenting agent and nitrogen-protecting deodorant, mix, compost thickness is not less than 2 meters, and volume is not less than 100 cubic metres, composting 12~14 days; Every turning in 3~5 days once, reduce to below 20% after temperature is increased to 60 ℃, promptly produce organic fertilizer until water content.
Horsehit is inoculated in the pig manure, and by twice thermophilic fermentation, purifying, amplification high temperature fiber bacterium are wherein prepared fermenting agent.The purpose of using this microbial inoculum is the microbiological degradation process that starts rapidly in the compost, improves the composting temperature, sterilizes effectively and shortens fermentation time.
Sun power Isolation warm house function is to absorb sun power, improves envrionment temperature, both has been of value to the insulation dehydration in the pig manure composting process, is beneficial to again and prevents that foul smell from distributing, and realizes cleaner production.
The nitrogen-protecting deodorant function is:
A. absorb protein and decompose the ammonia that discharges, reduce ammonia volatilization, improve the fertilizer fertilizer efficiency.Its principles of chemistry are:
NH 4 ++CaSO 4→Ca 2 ++(NH 4) 2SO 4
B. deodorizing.Ammonia is one of main component of pig manure foul smell, so calcium sulfate is absorbing ammonia, reduces volatilization, has the de-odorised function when improving fat effect;
C. the organic acid that produces with organic matter decomposition in, the pH of compost material changes in the buffering organic matter decomposition process, is of value to the lasting vigorous activity of microorganism, reduces moisture, promotes to become thoroughly decomposed.
Similarly regional in China southwest and weather condition, to utilize the inventive method to handle pig manure and produce fertilizer, need 15~20 days summer approximately, 45~50 days winters.
Advantage of the present invention is:
1, compost starts soon, fast 1~2 day than common compost start time; Time is short, and need 15~20 days summer, 45~50 days winters, and common compost needs more than 30 days summer at least, surpasses 3 months winter, even can not effectively handle pig manure under field conditions (factors) and produce fertilizer; The temperature height, top temperature can reach 65 ℃, and deodoring and disinfecting is thorough, and the top temperature of common compost is 55~60 ℃.
2, the nitrogen-protecting deodorant cost is low, and the source is wide, and is effective.Use after the nitrogen-protecting deodorant, the fertilizer nitrogen content can improve more than 25%, and the foul smell in the composting fermentation process obviously reduces, and the pH luffing reduces.
3, all processes of organic fertilizer production all carries out in the sun power Isolation warm house, has effectively stoped the diffusion of pig manure and nutrient, and foul smell secondary pollution such as distributes, and has realized cleaning and has handled pig manure and produce fertilizer.In addition, aspect structure design and material use, fully absorb sun power, improve envrionment temperature, and prevent that heat scatters and disappears, being of value to behind the fermentation reactor system later stage of fertilizer becomes thoroughly decomposed and dehydrates.
4, be fit to rainy, moist, that winter temperature is on the low side southwest and similar area, invest little, less energy consumption, cost is low, and is simple to operate, practical, easy popularization.
