Fertilizer for organic and inorganic fertilizers using fly ash and its manufacturing method

摘要

The present invention relates to a method for producing fertilizer for agricultural use, which comprises mixing fermentation of fly ash and organic wastes generated from a thermal power plant or the like to produce a good organic / inorganic compound fertilizer, as well as recycling a large amount of waste, 30 to 35 parts by weight of sawdust generated in the processing of wood products, 30 to 35 parts by weight of dehydrated squid sludge; Mixing and stirring the fly ash in the fly ash produced during coal combustion by 30 to 35 parts by weight in the same weight ratio as the sawdust; A fermentation process in which the mixture is transferred to a fermentation tank and fermented at 50C to 60C for 10 to 14 hours so that moisture is reduced and odors are removed; After the primary fermentation process, the squid sludge is added to the initial weight, and then the temperature is maintained at 50C to 60C in the reaction tank maintaining the constant temperature. Fermentation A second fermentation process that continues the fermentation process; The temperature change after the fermentation process rapidly rises to 60C or higher in the first 1-2 days, and the temperature is maintained for 3-4 days. After that, the temperature gradually decreases to maintain the room temperature after about one week. ) Is also related to the production of organic and inorganic compound fertilizers using coal fly ash which is initially prepared by organic acid synthesis by bacteria and then reduced to 5-6, then increased to 9, then dropped again and stabilized at around 8.
