Embodiment 1

[0021] To collect the waste liquid produced by an enterprise in the production of reconstituted tobacco leaves by papermaking method to produce natural amino acid water-soluble fertilizer, the specific steps are as follows:

[0022] a) Filtration and separation of waste liquid from reconstituted tobacco leaves by the papermaking method, with a filter mesh of 40 meshes; the waste liquid from reconstituted tobacco leaves by the papermaking method can be the extraction section, evaporation concentration section, coating section, and copying molding of reconstituted tobacco leaf production The waste liquid produced by any one of the production stages or the mixed waste liquid of two or more production stages;

[0023] b) Add 0.3% protease and 10% feed-grade protein powder to the waste liquid obtained in step a) according to the mass ratio, and send it into a constant temperature reactor. The fermentation temperature is 33°C-38°C, and the reaction time is 5-20 days; The protease is...

Embodiment 2

[0030] a) Filtration and separation of waste liquid from reconstituted tobacco leaves by papermaking method, with a filter mesh of 50 meshes; the waste liquid from reconstituted tobacco leaves by papermaking method is the waste liquid produced in the extraction section of reconstituted tobacco leaf production;

[0031] b) Add 0.45% protease and 15% feed-grade protein powder to the waste liquid according to the mass ratio, and send it into a constant temperature reactor. The fermentation temperature is 33°C-38°C, and the reaction time is 5-20 days; the protease is commercially available Papain, feed grade protein powder is silkworm chrysalis powder;

[0032] c) Add 8% water-soluble calcium calcium formate to the fermented product obtained in step b) according to the mass ratio, and mix and stir evenly;

[0033] d) Filter and separate the material obtained in step c), the mesh number of the filter is 50 mesh; the liquid phase obtained by filtration and separation is sent to the ...

Embodiment 3

[0038] a) Filtration and separation of waste liquid from reconstituted tobacco leaves by papermaking method, with a filter mesh of 60 meshes; the waste liquid from reconstituted tobacco leaves by papermaking method can be the waste liquid and mixed waste liquid;

[0039] b) Add 0.6% commercially available protease, 20% bean curd and fish meal mixture to the mixed waste liquid obtained in step a) according to the mass ratio, and send it into a constant temperature reactor with a fermentation temperature of 33°C-38°C. Time 5-20 days;

[0040] c) Add 5% water-soluble calcium chelated calcium to the fermented product obtained in step b) according to the mass ratio, and mix and stir evenly;

Abstract

The invention discloses a method for producing natural amino acid water-soluble fertilizer by utilizing tobacco liquid waste regenerated by a paper-making process. The method comprises the following steps: filtering and separating the tobacco liquid waste regenerated by the paper-making process, wherein the granularity of a filtering net is 40-60 meshes; adding 0.3-0.6 percent of protease and 10-20 percent of feed grade protein powder into the liquid waste at a mass ratio, feeding the mixture into a constant temperature reactor, and performing fermentation reaction at a temperature of 33-38 DEG C for 5-20 days, thereby obtaining a fermented product, and the like. The method is simple and low in production cost, the obtained product is the natural amino acid fertilizer, and after the fertilizer is applied, the crop growth can be promoted, and the soil structure is improved. The problems that the wastewater treatment cost is high, the discharge amount is large and environmental pollution is caused in the process of producing the regenerated tobaccos by the paper-making process are solved.

Description

technical field [0001] The invention relates to the technical field of preparation methods of bio-organic water-soluble fertilizers, in particular to a method for producing water-soluble fertilizers by using papermaking method to regenerate tobacco leaf waste liquid. Background technique [0002] Papermaking reconstituted tobacco leaf, also known as tobacco flakes, is a smoke-like product made from tobacco by-products and waste materials and improved by modern extraction and separation technology combined with traditional papermaking technology. In addition to a large amount of organic matter and trace element nutrients contained in general agricultural production residues, this kind of tobacco raw material is also rich in threonine and tryptophan. After the extraction and concentration process, this part of nutrients is transferred to the production The extract is added back to the tobacco sheet substrate as flavoring substances. However, in actual production, complete bac...
