Abstract

The invention discloses a novel method of the harmless treatment and utilization of livestock and poultry which died of disease according to the steps as follows: firstly, various kinds of the animal bodies of the livestock and the poultry which died of disease are collected; secondly, the animal bodies are crushed; thirdly, the crushed animal bodies are sterilized under high temperature and highpressure and separated for filtering, the material of oil and fat flows into a cooling pool, and the material of hair and bone is dried; fourthly, the material of hair and bone after drying is carbonized; fifthly, the material of oil and fat after cooling is added with catalyst, high-efficiency compound microorganism, trash, organic wastewater and sludge; sixthly, the mixed organic material is put into an anaerobic tower to be fermented, and then biogas, biogas slurry and biogas slag are processed for three-phase separation; seventhly, the biogas is used for burning and generating electricity; eighthly, the biogas slurry inside a fertilizer storing pool is used as farmland fertilizer; ninthly, the biogas slag is added with the high-efficiency compound microorganism and the catalyst for secondary ferment; tenthly, the material after the secondary ferment is made into agricultural high-efficiency organic fertilizer. The invention solves the problem of the environmental pollution caused by the livestock and poultry which died of disease and change the waste livestock and poultry which died of disease into valuables.

Description

technical field [0001] The invention relates to an environmental protection technology, in particular to a new method for harmless treatment and utilization of sick and dead livestock and poultry bodies. Background technique [0002] With the rapid development of my country's animal husbandry towards intensification and scale, in 2006, the number of pigs raised nationwide exceeded 681 million, beef cattle 45 million, mutton sheep 180 million, and poultry 15 billion. 2%, poultry 5%), at least 13.62 million pigs, 900,000 cattle, 3.6 million sheep, and 750 million poultry die every year. The environmental pollution and health hazards caused by the dead livestock and poultry have attracted attention. . Especially in recent years, major epidemics such as avian influenza, oral disease, mad cow disease, suis streptococcal disease, and rabies have frequently broken out at home and abroad, posing a great threat to human health and causing a series of public health problems.

AI Technical Summary

Problems solved by technology

A large number of livestock and poultry needs to be culled when an epidemic occurs. If the harmless treatment cannot be carried out in time, the culling of the epidemic will be caught off guard, which will seriously affect the effective control of the epidemic and cause large-scale spread, which will be devastating to the production and trade of animal husbandry. impact, and then have a serious impact on social life, economic order, and even the political situation

[0004] Second, it directly causes environmental pollution

At present, the vast majority of cities in my country do not have emergency treatment capacity for sick and dead livestock and poultry. The harmless treatment of sick and dead animals and products is often not complete and standardized in the slaughtering and processing links. Some slaughterhouses, butchers, and butchers even Selling sick and dead livestock and poultry at low prices to illegal traders, who then process them and re-flow them into the market, is bound to cause serious harm to the health of social residents
