Method for killing quarantine pests in wool processing leftovers through biological fermentation

Abstract

The invention discloses a method for killing quarantine pests in wool processing leftovers through biological fermentation. The method comprises the steps of (1) preparing complex microbial inoculants, (2) pre-processing the wool processing leftovers, (3) forming a pile body, (4) performing preliminary fermentation and (5) performing high-temperature batch fermentation. Auxiliary materials and high-temperature complex microbial inoculants are added into the leftovers and wastes to perform compost fermentation by means of a biological fermentation method, the heat-producing bacterium effect in the complex microbial inoculants enable the pile body temperature to rise and drop intermittently, and a compost is converted into an organic fertilizer to be reused on the premise that pathogenic microorganism and weed seeds in introduced wool processing leftovers are ensured to be killed or removed. On the one hand, agricultural production safety in our country is ensured, and land resources and environment are protected; and on the other hand, the cost input and energy consumption of manufacturing enterprises are reduced, the using amount of chemical fertilizers used in crop growth is decreased, and organic agriculture development and resource recycling are promoted.

Description

technical field [0001] The invention belongs to the technical field of applying biological fermentation technology to the killing of quarantine harmful organisms in wool processing leftovers, and in particular relates to a method for killing quarantine harmful organisms in imported wool processing leftovers by using biological fermentation. Background technique [0002] With the rapid development of my country's wool spinning industry, wool imports are increasing year by year. Especially in recent years, the wool spinning industry has developed at an astonishing speed. The annual wool processing volume in my country has exceeded 50% of the world's output, reaching about 500,000 tons. Among them, imported wool accounts for 70%. The actual wool processing volume in my country may reach about 800,000 tons per year, and more than 200,000 tons of wool processing waste or waste will be generated. Relevant data show that harmful organisms that can be transmitted through wool and its...

AI Technical Summary

Problems solved by technology

Use the leftovers of wool processing to make organic fertilizer. On the one hand, wool wastes are not suitable for direct composting and fermentation due to their small particle size and high specific gravity. On the other hand, some heat-resistant bacillus can tolerate higher temperatures in the spore state. , the conventional fermentation and composting process cannot guarantee that the fermentation temperature is sufficient to kill all quarantine harmful organisms including bacillus in the inbound wool processing waste
