Process for preparing liquid fertilizer by using enzymolysis and fermentation of animal bloods and taking oil supply angle as defoaming agent

Abstract

The invention discloses a process for preparing a liquid fertilizer by using the enzymolysis and fermentation of animal bloods and taking an oil supply angle as a defoaming agent, and belongs to the technical field of bioengineering. For solving the problems that in the past, the bloods poured from slaughterhouses in the process of red overglazing are all used as a raw material for producing feed additives, once the bloods are not cleaned and transported timely, the potential safety hazards of feeds caused by the decomposition of the bloods, the environmental pollution caused by organic wastewater, and the economic losses are caused, the invention provides a process for preparing a liquid fertilizer by using the enzymolysis and fermentation of animal bloods and taking an oil supply angle as a defoaming agent, and the process is implemented by taking animal bloods (pig blood, cattle blood, sheep blood and donkey blood and the like) as the main raw materials of a fermentation substrate and being supplemented by brown sugar, white sugar, an oil supply angle, protease, associated strains, wherein the oil supply angle especially achieves an important effect of preventing the losses of materials caused by overflowing in the process of heating and sterilization of raw and auxiliary materials, thereby avoiding the secondary pollution of the environment, and meanwhile, the organic phosphorus content is increased.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and relates to a process for preparing liquid fertilizer by using animal blood enzymolysis and fermentation synchronous method and using oil horn as a defoaming agent. Background technique [0002] China is a big meat production and consumption country in the world. In recent years, with the improvement of people's living standards, the demand for livestock and poultry food has increased year by year, which has led to the unprecedented development of the breeding industry. my country has a large amount of livestock and poultry slaughtered every year, and blood resources are very rich. In the past, the blood poured out of the slaughterhouse during the red smearing process was used as the raw material for the production of feed additives. Once it was not cleared and transported in time, corruption would cause hidden dangers in feed safety, environmental pollution by organic wastewater, and e...
