Description
Technical field
It is especially a kind of aerobic to animal wastes progress using composite membrane the present invention relates to animal wastes processing technology field
The method of harmless treatment.
Background technology
Growing with large-scale cultivation industry, pollution of the animal wastes to environment in cultivation is increasingly severe, moves
Thing night soil-treatment is improper to cause very serious pollution to air, water body, soil etc., because animal wastes are in anaerobic digestion
Substantial amounts of CH can be produced4、NH3、H2S、（NH4）2The foul smelling such as S and scatol and harmful gas, the animal after anaerobic digestion
Excrement is also with substantial amounts of germ, parasitic ovum, and the material such as substantial amounts of nitrogen, phosphorus, therefore it is necessary to be carried out to animal wastes
Harmless treatment.
Current China mainly has three kinds to the harmless treatment of animal wastes and recycling mode：Producing methane, make fertilizer
Expect, make feed.But because the animal wastes harmless treatment of various odjective causes plant domestic at present is mostly
By the way of organic fertilizer is made.And the animal wastes making general processing mode of organic fertilizer is as follows：
Animal wastes are mixed after the auxiliary materials such as wooden chaff stir into stacking to ferment, but which is because excrement is without deodorization,
Air can be polluted when mixing with substantial amounts of foul odour.
The content of the invention
The purpose of the present invention is：Overcome deficiency of the prior art, there is provided one kind is carried out using composite membrane to animal wastes
The method of aerobic harmless treatment, using the processing method, on the one hand, degrade caused foul smell during the fermentation, green
Environmental protection, on the other hand, whole fermentation process is without heating, it is only necessary to by adjusting temperature of the ventilation can to regulation fermentation heap
Degree, energy consumption is saved, reduces cost.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
A kind of method that using composite membrane animal wastes are carried out with aerobic harmless treatment, the described method comprises the following steps：
（1）Animal wastes compression water removal, obtains the excrement of preliminarily dried；
（2）Dispensing：To step（1）Excrement addition strain, nitrogen, the dry material of middle preliminarily dried carry out dispensing；
（3）Turn over and cut open mixing windrow：Select vacant lot, on vacant lot grooving nuzzle tracheae, the upper surface of air inlet pipe and ground level, enter
The both sides of tracheae are symmetrically provided with some air admission holes, by step（2）In the animal wastes that prepare pile up the top of air inlet pipe, pass through drum
Blower fan carries out air blast from air inlet pipe to fermentation heap；
（4）Overlay film, aerobic fementation, turn within 2 weeks and cut open once, 30 days terminate；
（5）Ageing, ageing are turned over 1 time for 2-3 months.
Preferably, the step（1）The moisture content of the excrement of middle preliminarily dried is 55-65%.
Preferably, the step（2）The addition of middle strain for 10 tons of preliminarily drieds excrement add 0.8-1.2kg strains,
1.8-2.5kg urea.
Preferably, the step（2）The middle carbon for having added the animal wastes after strain and nitrogen, nitrogen ratio are 20:1.
Preferably, the step（2）In dry material select rice bran or plant ash.
Preferably, the step（4）Middle aerobic fementation is ventilated using batch (-type), ventilation 30min pauses 15min.
Preferably, the draft speed of the aerobic fementation is determined according to the temperature of fermentation heap, when the temperature of fermentation heap is less than
At 50 DEG C, ventilation speed is adjusted to low grade, when the temperature of fermentation heap is higher than 50 DEG C, during less than 70 DEG C, during ventilation speed is adjusted to
Shelves, when fermentation heap temperature be higher than 70 DEG C, ventilation speed is adjusted to top grade.
Preferably, the moisture content of the animal wastes after the ageing is less than 30%.
Preferably, the step（4）In middle overlay film operation film is passed through using anti-ultraviolet selectivity.
It is using the beneficial effect of technical scheme：
1st, the draft speed of aerobic fementation is determined according to the temperature of fermentation heap in the present invention, when temperature is less than 50 DEG C, by ventilation speed
Degree is adjusted to low grade, and now ventilation mainly improves the oxygen content inside fermentation heap, accelerates aerobic fermentation, increases heat production, works as fermentation
The temperature of heap is higher than 50 DEG C, during less than 70 DEG C, and ventilation speed is adjusted into middle-grade, and now oxygen content and the speed of fermentation heat production are fitted
Preferably, middle-grade is adjusted than convenient；When fermentation heap temperature be higher than 70 DEG C, now need increase throughput, will be produced in fermentation heap
Unnecessary heat discharge in time, in time radiating, ventilation speed is adjusted to low grade；Operating procedure is simple, and energy consumption is low；
2nd, film is passed through using anti-ultraviolet selectivity in the present invention, anti-ultraviolet function, improves the ageing resistace of film,
Service life is extended, selectivity passes through, and refers to that the micro-molecular gas such as hydrone can pass through, and gas frowzy can not pass through,
On the one hand the rate of drying of animal wastes is accelerated, on the other hand, avoids foul smell from being directly discharged to air, causes environmental pollution.
