Process method for preparing organic fertilizer from animal blood

Abstract

The invention provides a process method for preparing an organic fertilizer from animal blood. Livestock blood which originally needs to be treated by a large amount of money in a slaughter house is fully utilized as a raw material and is subjected to biological treatment such as multi-stage protein hydrolysis, emulsification, enzymolysis, fermentation and the like; according to the method, the livestock blood is changed into a microbial organic fertilizer to be returned to the field, secondary treatment tailings are not generated, the problem of environmental pollution is thoroughly solved, the additional value is increased, the prepared organic fertilizer is mainly used for improving soil beneficial microbial communities, and the effects of effectively improving soil, improving soil activity, increasing crop yield and improving fruit quality are achieved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a process for preparing organic fertilizer by using animal blood. Background technique [0002] With the improvement of people's living standards, the demand for meat products is increasing, which drives the unprecedented development of the aquaculture industry. In order to ensure food safety, the state compels all livestock such as live pigs and cattle to enter the market after they have passed the quarantine inspection and are slaughtered in a centralized manner. There is a large amount of livestock slaughtered in my country every year, and centralized slaughter will produce a large amount of livestock blood, which is usually treated by direct discharge, which will cause environmental pollution. However, livestock blood is rich in animal protein and oil, which are excellent organic fertilizer sources. Therefore, the use of livestock blood to make org...

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a process for preparing organic fertilizer by using animal blood. The present invention makes full use of the raw material of livestock blood that needs to be processed with a large amount of money in slaughterhouses, and turns it into microbial organic fertilizer after biological treatment. Returning to the field without secondary treatment tailings, not only completely solves the problem of environmental pollution and increases added value, but also the fertilizers produced by it mainly improve the beneficial microbial communities in the soil, so as to effectively improve the soil, increase soil activity, and improve crop yield. Yield, the effect of improving fruit quality is obvious
