Problems solved by technology

[0006] In order to solve the traditional method of improving saline-alkali land, a large amount of water is required to drain the salt, and the saline-alkali in the saline-alkali land is flushed into the river canal. This method not only wastes water resources but also is prone to alkali return. Loss of soil nutrients, forming a vicious circle

Embodiment 1

[0038] The present embodiment provides a method for producing improved solid-liquid bio-organic fertilizer in saline-alkali land with slaughtering and breeding waste sewage and biogas slurry from dead livestock and poultry straws, and the process is carried out according to the following steps:

[0039] Step 1: Classify the slaughtering waste and wastewater into five treatment units, in which the hoof horns, bones of livestock and poultry and whole heads of diseased livestock and poultry are combined into the first processing unit; The second processing unit uses livestock and poultry hair as the third processing unit, and combines biogas slurry or urine separated from solid-liquid from livestock and poultry manure, as well as livestock and poultry blood and blood-containing sewage into the fourth processing unit; the slaughter workshop is combined. Any one or more of the excrement, biogas residue and excrement that came out of the intestines were separated into solid-liquid an...

Abstract

The invention discloses a method for producing solid-liquid bio-organic fertilizer on saline-alkali land from slaughtering and breeding waste sewage and dead livestock and poultry stalk biogas slurry, and belongs to the technical field of organic fertilizer preparation. The method is to sterilize raw materials such as waste water from slaughterhouses and farms, sick and dead animals, etc., and then compound them with whey powder, brown sugar and cornmeal, then add keratinase, papain, alkaline protease and lipase for enzymatic hydrolysis, and inoculate milk Bacillus and yeast fermentation, and then inoculated with Bacillus licheniformis and jelly-like Bacillus for fermentation. After the fermentation is completed, the supernatant obtained by filtering is liquid bio-organic fertilizer, and the sediment is compounded with crushed straw, manure or biogas residue after fermentation. Compound with straw carbon powder to make solid bio-organic fertilizer. The liquid microbial organic fertilizer and the solid organic fertilizer of the present invention can provide hosts and continuous nutritional support for soil beneficial microorganisms, can neutralize, degrade and transform saline-alkaline nitrate in saline-alkali land, and can improve soil ecological vitality in saline-alkali land.

Description

technical field [0001] The invention relates to a method for producing improved solid-liquid bio-organic fertilizer for saline-alkali land with waste sewage from slaughtering and breeding, and biogas slurry from dead livestock and poultry straw, and belongs to the technical field of organic fertilizer preparation. Background technique [0002] The slaughterhouse has always been the most polluted in the food processing industry. The slaughtering waste, blood, hoof horns, hair, scraps and bones, and blood-containing sewage, including the sick and dead livestock and poultry in the process of pulling and transporting and the sick and dead livestock and poultry in the farm, if not handled properly, it will cause damage. It has serious environmental problems and the risk of the spread of pathogenic bacteria, but this is precisely the most abundant source of crop organic matter. As long as it is sterilized at high temperature or ultra-high temperature, and then connected to benefici...
