Production equipment for anaerobic digestion liquid organic compound fertilizer

Abstract

The invention relates to production equipment for anaerobic digestion liquid organic compound fertilizer, which is characterized by comprising a solid-liquid separation device, a sedimentation filtering tower, a repeated ferment (acid enriching) device, a flocculation sedimentation filtering device, a high-speed separation device, a complexing device, a blending device, a cooling heat transfer device, an ultrafiltration device, a finished product device, a canning machine, accessories such as a motor, a pump, a pipeline, a control cabinet (meter) and the like and auxiliary equipment which areconnected sequentially. A method for producing the organic compound fertilizer comprises the following steps of: firstly, performing solid-liquid separation on biogas residue liquid; secondly, takingseparated biogas residues as a carrier for preparing solid fertilizer; thirdly, subsiding separated biogas liquid to remove the biogas residues further, acidizing, flocculating, separating, complexing, blending and cooling the biogas liquid sequentially, and filtering to obtain a finished product; and finally, canning and warehousing the finished product. By the production equipment, multiple functions are integrated into a whole, a large amount of discharged biogas residue liquid can be treated efficiently in time, the environment is purified, the pollution is reduced, and the economic benefit is improved, so the production equipment can be widely used in the treatment process of the biogas residue liquid in biogas engineering.

Description

technical field [0001] The invention relates to a compound fertilizer production equipment, in particular to an anaerobic digestion liquid organic compound fertilizer production equipment which uses the separated biogas liquid as a carrier to prepare foliage fertilizer, fertilize by flushing, and soilless culture nutrient solution. Background technique [0002] In recent years, with the rapid development of the aquaculture industry, the advancement of new rural construction, and the comprehensive development and utilization of surplus crop straw, the rural biogas industry has been greatly developed. However, with the development of biogas construction, the rational development and utilization of biogas slurry has become a very difficult problem, especially the utilization of biogas slurry is particularly prominent. At present, in the large-scale biogas projects built in the country, a large amount of biogas residue discharged every day is mostly stored in liquid storage pits...

AI Technical Summary

Problems solved by technology

At present, in the large-scale biogas projects built in the country, a large amount of biogas residue discharged every day is mostly stored in liquid storage pits (pools) and used in the fertilization season. Therefore, it is necessary to build a large storage pool, but the anti-seepage treatment will emit odor issues have not yet been fully resolved

Moreover, the long-term storage of biogas residue liquid is washed out and evaporated by rainwater, causing environmental problems caused by mosquitoes and flies, which is also very serious, and the fertilizer efficiency will be greatly reduced. It cannot meet the national commercial fertilizer standards, and it is difficult to enter market

Moreover, this seasonal fertilization method is also restricted by transportation distance and cost, and the method and equipment of fertilization have not yet met the requirements of ease of use, so it is difficult to promote
