Method for producing high-efficiency organic liquid fertilizer by utilizing methane liquid and equipment used in method

Abstract

The invention provides a method for producing high-efficiency organic liquid fertilizer by utilizing methane liquid and equipment used in the method. The method for producing liquid fertilizer comprises nine process steps of: sedimentating the methane liquid; fermenting with aeration; performing solid liquid separation; performing humic acid reaction; sedimentating raw materials of the humic acid reaction; adding other raw materials, blending and complexing; placing into a finished product tank; encapsulating; and packaging. The equipment used in the method consists of a primary raw material pipeline, a sedimentation tank, a sedimentated raw material liquid-absorbing pipe, a fan, a fan pipeline, an aerated fermentation tank, an aeration device, a fermenting raw material liquid-absorbing pipe, a solid-liquid separation device, a separating liquid collecting tank, a clear liquid conveying pipeline, a humic acid reaction kettle, a humic acid reaction liquid conveying pipeline, a humic acid reaction liquid sedimentation tank, a humic acid reaction liquid conveying pipeline after sedimentation, a blending complexing reaction kettle, a finished production conveying pipeline I, a finished product storage tank, a finished product conveying pipeline II, an encapsulation machine, an encapsulation pipeline, a plurality of liquid-absorbing pumps and a plurality of pipeline valves. The invention has the advantages that: large-scale production is realized conveniently; and the prepared liquid fertilizer has high nutrient content.

Description

technical field [0001] The invention relates to a method for producing organic liquid fertilizer and the equipment used therein, in particular to a method for producing high-efficiency organic liquid fertilizer by using biogas slurry and the equipment used therein. Background technique [0002] At present, in the production of organic liquid fertilizer by using biogas slurry, some of them are processed by sand filtration (i.e. filtration), reverse osmosis treatment (i.e., water is separated from the biogas slurry by pressurized concentration), and the recycled water is disinfected with ozone Sterilize, add nitrogen, phosphorus, potassium and other effective nutrients to the biogas slurry concentrate and ferment with beneficial bacteria to obtain organic liquid fertilizer and reusable water; some use biogas slurry as the base medium and use Bacillus subtilis to make First-level seed liquid, second-level seed liquid, and third-level seed liquid, use seed liquid to cultivate bi...

AI Technical Summary

Problems solved by technology

The above several methods of using biogas slurry to produce organic liquid fertilizer have complicated production procedures and troublesome operation, and are not suitable for industrialized and large-scale production of organic liquid fertilizer from biogas slurry. The comprehensive utilization benefit of biogas slurry is not high. The nutrient content of the organic liquid fertilizer is not high, and it is not comprehensive and reasonable enough.
