Organic-inorganic compound fertilizer based on pesticide intermediate by-product and preparation method for organic-inorganic compound fertilizer

Abstract

The invention provides an organic-inorganic compound fertilizer based on a pesticide intermediate by-product. The organic-inorganic compound fertilizer comprises a pesticide waste liquid concentratedsolution, humic acid, an amino acid stock solution, potassium sulfate, compound trace elements and compound sodium nitrophenolate. According to the invention, rich nitrogen in the pesticide waste liquid concentrated solution generated in the pesticide production process is fully utilized, so the problem of environmentally-friendly emission is solved, and the raw material source of a high-quality organic-inorganic compound fertilizer is found, while waste is turned into treasure; the organic-inorganic compound fertilizer rich in organic matters and mineral nutrition is formed through compounding processing, so the problem of environmental pollution caused by pesticide waste liquid treatment or wastes is avoided, and the production cost of the organic-inorganic compound fertilizer is also reduced at the same time; and thus, significant ecological benefits and economic benefits are achieved. The invention further provides a preparation method for the organic-inorganic compound fertilizerbased on the pesticide intermediate by-product. The organic-inorganic compound fertilizer treated by using the method provided by the invention can prevent the pesticide waste liquid from polluting soil, improve organic matters of soil and provide rich nutrition for crops.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to an organic-inorganic compound fertilizer based on by-products of pesticide intermediates and a preparation method thereof. Background technique [0002] At present, due to many reasons such as fertilization habits, concepts, food demand, and economic benefits, people fertilize mainly chemical fertilizers, and insufficient application of organic fertilizers leads to problems such as soil acidification, compaction, decreased buffering capacity, and poor fertilizer absorption effect. The quality declines, which makes it difficult for agricultural production to achieve sustainable development; at the same time, the fertilizer consumption market is also developing in the direction of high concentration, compounding and slow effect. Therefore, compound fertilizers will have broad development prospects, and will replace single chemical fertilizers and ...

AI Technical Summary

Problems solved by technology

[0004] Nicotinic pesticides will generate a large amount of waste liquid during the production process, such as oxadiazine, methyl nitroguanidine and imidazolidine, which will produce a foul smell during storage or discharge, which seriously pollutes the ecological environment
