Description
Technical field
The present invention relates to livestock and poultry farm waste resource utilization technology field, it is more particularly to a kind of pig manure and continuously increases
The device of oxygen hot fermentation organic fertilizer, it is suitable for the utilization of Intensive Farm of Pig Raising pig manure Fertilizer Transformed or distributed pig farm pig
Excrement, which is collected, concentrates Fertilizer Transformed processing to utilize.
Background technology
With the fast development of livestock and poultry breeding industry, have to the demands such as meat, eggs and milk and agro based economic development for meeting people
There is very important effect, however animal waste discharge causes serious pollution to ecological environment.Country is to livestock and poultry
Environmental pollution caused by cultivation gives the attention of height, to accelerate to promote animal waste processing and recycling,
In national animal waste recycling meeting, animal waste recycling is done a good job of it, is concerning livestock products
The great people's livelihood engineering of effective supply and rural resident's production and living enhancement of environment.Therefore, animal waste recycling profit
It is the key that the utilization of waste as resource solved in current livestock and poultry breeding industry fast development with the research and development of device and technology, it is right
Development and the agriculture environmental protection etc. for ensureing livestock and poultry breeding industry are of great significance.
Carry out more research for the recycling of animal waste, but disclosure satisfy that reality at present
The technology applied in the production of border is less.Pig manure wheat straw is forced under the conditions of Lv Huangzhen etc. (2008) reports laboratory simulation
It is 20 that aerobic compost optimum condition of divulging information, which is carbon-nitrogen ratio,:1, material initial water content be 65%, ventilation quantity be 0.34 liter/(point
Clock kilogram), fermentation maximum temperature occurred at the 3rd day or so, and the heap body maximum temperature of fermentation is 68.5-70.9 DEG C, this
Temperature declines afterwards, and heap body is only 5.1-6.8 days in 50 DEG C or more of temperature, and without carrying out scale plant produced.And
What Ministry of Health of the People's Republic of China announced for 1987《Decontamination of human excreta sanitary standard》(GB7959-87) compost highest is required
Heap temperature continues 5-7 days up to 50-55 DEG C or more.Wang Wei equalitys (2009), which are reported in pig manure, adds 20% (weight ratio)
Rice chaff fermentation compost processed is best, but using artificial turning 3 days 1 time, time and effort consuming.Li Ronghua etc. (2014) is by pig manure:
Rice husk is with dry mass than 1:After 2 mixing, the charcoal of 2.5%-10% is added, carries out aerobic fementation experiment in the lab, as a result
Show to reach highest fermentation temperature in 7-10 talentes, highest fermentation temperature is 63.8-66 DEG C, in 50 DEG C or more megathermal periods
Between be 11-16 days, addition charcoal can increase the nitrogen content of compost, but can increase compost cost.Deng is small to cultivate etc. (2014
Year) with banana stem, eucalyptus barks and pig manure carrying out compost fermentation, the results showed that windrow carbon-nitrogen ratio is 25-27:1 compost temperature
Higher, heap temperature reaches 56 DEG C or more, and 50 DEG C of high temperature or more can maintain 10-11 days, but uses artificial turning 5 days 1 time, time-consuming
Arduously.Burnt flood studies different ventilation quantities to pig manure and maize straw and rice husk heap fertilizer efficiency in superfine (2008) with ventilating fermentation case
The influence of fruit, stalk show that ventilation quantity is preferable with 0.3 cubic meters per minute, interval time more a length of 90 points of stopping but it is divulged information
Clock rear venting 1-2 minutes, in addition windrow thickness is only 0.5 meter too low, and windrow temperature is caused to be kept for 50 DEG C or more of time short,
Only 4-5 days.204162619 U of Chinese invention patent CN (2015) disclose a kind of sludge aerobic compost fermentation bottom and increase
Oxygen device, the device are on gas distributing pipeline by having filled multiple aerating pipes, but its aerating pipe is easy to block, while also not being explained
Bright ventilation device.106278487 A of CN (2017), which are disclosed, a kind of preparing organic-nothing using afforestation castoff compost
The automatic control device and method of machine mixed fertilizer, but the device is complex, and need to heat, device and production cost are all
It is higher.1012003680 A of CN (2008) disclose a kind of adjustable spiral agitating type with greenhouse temperature increasing and compulsory oxygen aeration
Composting device, but the degree of automation of this method is low, and oxygenation process needs manual operation, is more troublesome.CN 203346299 U
(2013) disclose a kind of aerobic static composting reactor assembly, but this device is pretty troublesome, to be carried out to the raw material of fermentation
Pack, artificial to stack, labor intensity is big.1043268230 B of CN (2016) disclose a kind of compound organic and inorganic fertilizer and system
Preparation Method prepares organic fertilizer, but the specific method not prepared about organic fertilizer using cow dung and rape cake fermentation.
Therefore, it is badly in need of building device and the side that a kind of device is simple, efficient livestock manure fermented prepares organic fertilizer at present
Method can be widely applied to various weather conditions and livestock and poultry type, carries out organic fertilizer replacing fertilizer action plan for country and establishes base
Plinth and offer key technology.
Invention content
