Abstract

The invention relates to a biological organic fertilizer and a preparation method thereof. The organic fertilizer is prepared from the following raw materials in parts by weight: (1) 50-80 parts of dewatered sludge, (2) 10-50 parts of protein waste slag, (3) 0-10 parts of urea, (4) 0-10 parts of activated carbon and (5) 0.2-1 part of functional strain microbial inoculum. The preparation method comprises the following steps: (1) preparing a functional strain; (2) fermenting the raw materials; and (3) performing post treatment. According to the invention, the problem of secondary environmental pollution caused by sludge generated in the mycelium CSTR (continuous stirred tank reactor) anaerobic fermentation, organic acid waste water EGSB (expanded granular sludge bed) anaerobic fermentation and aerobic treatment process and protein waste slag generated by organic acid factory microbial fermentation is solved; the waste is changed into valuable substances, thereby meeting the related requirements of circular economy; and the indices of the prepared biological organic fertilizer, such as the organic content, the active viable count and the like, meet the requirements of related industrial standards. Besides, the preparation method provided by the invention is simple and has the advantages of no discharge of three wastes, low investment, quick action and low cost.

Description

technical field [0001] The present invention relates to a kind of bio-organic fertilizer and preparation method thereof, specifically, relate to a kind of mycelia CSTR anaerobic fermentation, organic acid waste water EGSB anaerobic fermentation-aerobic treatment process produces sludge and organic acid factory The bio-organic fertilizer produced by aerobic fermentation by adding functional strains and aerobic fermentation of protein waste residue, waste activated carbon and other wastes produced by microbial fermentation and its preparation method. Background technique [0002] Bio-organic fertilizer is made of livestock and poultry manure, urban domestic garbage, crop straw, agricultural by-products and organic waste produced in food processing, and is equipped with a multi-functional fermentation strain agent to quickly deodorize, decompose, dehydrate, and then add Functional microbial agent is a processed organic fertilizer containing a certain amount of functional microo...
