Method for preparing biological organic fertilizer by using fermentation tank

Abstract

The invention discloses a method for preparing a biological organic fertilizer by using a fermentation tank. The method comprises the following steps of: (1) preparing a biological organic fertilizer fermentation tank; (2) mixing 60 to 70 weight percent of sludge, 30 to 40 weight percent of organic matters and 2 to 8 kinds of beneficial strains; (3) feeding the mixed materials into the fermentation tank, and fermenting in a sealed negative pressure environment; (4) controlling a heating mechanism, a humidifying mechanism, a turning, polishing and aerating mechanism and a strain adding mechanism to heat and humidify the materials, add the strains and turn, polish and aerate the materials in a reaction tank by using an automatic control system; and (5) extracting stink generated in the reaction tank by using an air extractor, feeding into environment-friendly equipment for treating, and fermenting and decomposing the materials in the reaction tank for 15 to 17 hours to obtain the biological organic fertilizer. By the method for preparing the biological organic fertilizer, fermentation time is short, the fertilizer is quickly discharged, production efficiency is high, the materials are driven to move forwards by a conveying belt, feeding, fermenting and discharging are connected, and the method is suitable for industrial production; and the stink is not generated in the production process, so the method is environment-friendly.

Description

technical field [0001] The invention relates to a bio-organic fertilizer, in particular to a method for preparing a bio-organic fertilizer with a fermenter. Background technique [0002] Bio-organic fertilizer refers to a type of microorganisms with specific functions, which are derived from animal and plant residues and compounded through rotting heat and harmless treatment. They have the effects of microbial fertilizers and organic fertilizers. Bio-organic fertilizers have complete nutrients , can improve the soil, improve product quality and quality, and is easy to apply. [0003] At present, the preparation method of bio-organic fertilizer is mainly stacking and fermenting in natural environment. Although this method is simple and low in investment, the fermentation conditions are not easy to control, the fermentation is slow, the production cycle is long, and the malodorous gas produced by the stacking process and the breeding of mosquitoes and flies affect the surroun...
