Method for preparing organic fertilizer by sludge fermentation

Abstract

The invention relates to a method for preparing an organic fertilizer by sludge fermentation, the method for preparing the organic fertilizer by the sludge fermentation adopts the following equipment for preparing the organic fertilizer by the sludge fermentation, and the equipment for preparing the organic fertilizer by the sludge fermentation comprises a moving carriage, moving rollers, a charging box and a piling device; and moving rollers are equidistantly mounted on the left and right sides of the lower end face of the moving carriage, a charging box is mounted on the upper end face of the moving carriage, and a stacking device is mounted in the moving carriage. The spraying unit and the clamping unit are matched to spray strains to each cake-shaped mixture, so that the strain spraying uniformity is guaranteed, and the mixture can be fully fermented; and the spraying range of the spraying unit can be changed by rotating the angle of the adjusting disc according to cake-shaped mixtures with different diameters through the spraying unit and superposing the adjusting holes and the blanking holes according to different positions.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a method for preparing organic fertilizers by fermentation of sludge. Background technique [0002] Mainly derived from plants and animals, carbonaceous materials applied to the soil to provide plant nutrition as their main function; processed and fermented from biomass, animal and plant waste, plant residues and sludge, the first stage of composting fermentation is The fermentation process characterized by the rapid decomposition of easily decomposable organic components in waste by microorganisms eliminates toxic and harmful substances and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and nitrogen, phosphorus, and potassium It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and che...

Problems solved by technology

[0004] (1) In order to ensure that the mixture can be fully fermented, the mixture will be sprayed with appropriate strains, and the strains will be sprayed directly on the surface after the pile is built. Since the mixture of piles has a certain height, the height of the pile mixture The interior cannot be sprayed with negative bacteria
