Background technique
Corpse after animal dead often carries a variety of diseases in spite of natural death or the animal carcass of epidemic disease death
Bacterium, if not handling or dealing with improperly, corpse can decompose quickly corruption, emitting offensive odor, make sex pheromone pollution air, water source and
Soil affects people's lives environment, causes the propagation and sprawling of disease, while directly or the people of mediate contact has
The possibility of infection.Have at present using the animal carcass after animal dead, prepares organic fertilizer after degrading using high-temperature biological, can promote
It circulates benignly into agriculture-stock production, protects environment, avoid sex pheromone pollution air, water source and soil, influence the life of people
Environment living, causes the propagation and sprawling of disease.
But the technique at present with animal carcass production organic fertilizer is not also overripened, and technique is unstable, influences people to animal
After death corpse be effectively treated and environmental protection.
Summary of the invention

Strong base solution is simultaneously stirred continuously, and strong acid solution is added after 1-2 days thereto until pH value stops acid adding after reaching neutrality；
Step 2: taking the crops stalk crushing of 100-150 parts by weight, and smashed agricultural crop straw and step 1 are handled
Rear animal carcass is added in reactor tank, then capping tank and is heated to 120-130 DEG C, pressure is controlled in 0.5-
0.7Mpa is persistently stirred in heating process, is stood 5-8 hour and is obtained reactant；
Step 3: reactant and microbial fermentation inoculum are carried out compost fermentation, the original water content for the windrow that ferments is 50-
60%, 45-50 DEG C of windrow temperature, microbial fermentation inoculum and fermentation windrow weight ratio be 1:1000；
Step 4: being evaporated moisture in windrow using fermentation temperature, windrow moisture content is gradually decreased in fermentation process, temperature by
Gradually decline, when windrow central temperature is down to 40 DEG C or less, spreads out to dry in the shade and obtain finished product organic fertilizer.
As the preferred technical solution of the present invention, the highly basic being added in the animal carcass in the step 1 after being pulverized is
Sodium hydroxide.
As the preferred technical solution of the present invention, the strong acid being added in the animal carcass in the step 1 after being pulverized is
Sulfuric acid.
As the preferred technical solution of the present invention, the microbial fermentation inoculum in the step 3 is nine biology section, nation of Henan
The BM animal carcass fermenting microbe of skill Co., Ltd production.
As the preferred technical solution of the present invention, the agricultural crop straw be rice straw, corn stover, wheat stalk,
Cassava stalk, peanut straw, soybean stalk, broad bean stalk, the one or more of rape stalk.
As the preferred technical solution of the present invention, the living bacteria count of the BM animal carcass fermenting microbe is greater than 50 Yi ∕
Gram (cfu/g).
Compared with prior art, the present invention using strong acid and highly basic, alternately corrode by animal carcass, being capable of animal corpse
The inactivation of pathogen in body, while can also accelerate the corrosion efficiency of animal carcass, then treated with soda acid by agricultural crop straw
Animal carcass airtight heating compressive reaction, can be to the further inactivation of pathogen in animal carcass, to reach harmless treatment
Purpose, most afterwards through with BM animal carcass fermenting microbe carry out fermentative degradation organic matter sufficiently decompose its nutritional ingredient, become
At good organic biofertilizer, crop will not be damaged, rational technology is easy to operate, energy conservation and environmental protection, processing method at
Ripe, process stabilizing.
