Embodiment 1

[0015] The method for producing a saline-alkali soil conditioner by utilizing the concentrated waste liquid of reconstituted tobacco leaves is as follows:

[0016] a) Take the waste liquid from the extraction section of the reconstituted tobacco leaf production by the papermaking method and carry out filtration and separation, the filter mesh number is 40 mesh, and the liquid phase part is sent to the concentration equipment for low-temperature vacuum concentration, and the solid content of the concentrate is 40%;

[0017] b) 85% concentrate, 15% corn stalks and sludge organic matter carrier and 2% microbial inoculant are mixed and mixed according to the mass ratio, and stirred evenly; the microbial inoculum is potassium-containing bacteria and subtilis with castor cake as the carrier Bacillus;

[0018] c) Drying the mixed material at low temperature to a moisture content of 18%-22%, and then sending it into a disc granulator for granulation;

[0019] d) Dry the granules with...

Embodiment 2

[0022] The method for producing a saline-alkali soil conditioner by utilizing the concentrated waste liquid of reconstituted tobacco leaves is as follows:

[0023] a) Take the waste liquid from the evaporation and concentration section of the reconstituted tobacco leaf production by the papermaking method and filter and separate it. The mesh number of the filter mesh is 20 mesh, and send the liquid phase part to the concentration equipment for low-temperature vacuum concentration. The solid content of the concentrate is 50%;

[0024] b) Mix 70% concentrate, 30% distiller's grains, phosphogypsum and 4% microbial inoculum according to the mass ratio, and stir evenly; the microbial inoculum is potassium-containing bacteria and Bacillus subtilis with castor cake as the carrier;

[0025] c) Drying the mixed material at low temperature to a moisture content of 18%-22%, and then sending it into a disc granulator for granulation;

[0026] d) Dry the granules with a particle size of 2-...

Embodiment 3

[0029] The method for producing a saline-alkali soil conditioner by utilizing the concentrated waste liquid of reconstituted tobacco leaves is as follows:

[0030] a) Take the waste liquid from the evaporation concentration section and the coating section of the reconstituted tobacco leaf production by the papermaking method, mix them, and then filter and separate them. The mesh number of the filter mesh is 30 mesh. The content is 55%;

[0031] b) Mix 65% concentrate, 35% cinder, chicken manure and sludge and 6% microbial inoculum according to the mass ratio, and stir evenly; the microbial inoculum is potassium-containing bacteria and subtilis with castor cake as the carrier Bacillus;

[0032] c) Drying the mixed material at low temperature to a moisture content of 18%-22%, and then sending it into a disc granulator for granulation;

[0033] d) Dry the granules with a particle size of 2-5 mm after granulation until the moisture content is lower than 14%.

Abstract

The invention discloses a method for producing a saline alkali soil conditioning agent through reconstituted tobacco concentrated waste liquor.Paper-making reconstituted tobacco waste liquor is obtained for filtering separation, a liquid phase portion is fed into concentration equipment to be subjected to low-temperature vacuum concentration, the solid content of the concentrate is 40-55%, 65-85% of the concentrate, 15-35% of an organic matter carrier and 2-6% of a microbial agent are mixed, blended and mixed to be uniform, and low-temperature drying is performed to till the water content reaches 18-22%, and drying is performed after granulation is performed till the water content is lower than 14%.According to the method, the waste liquor can become available resources, waste materials are changed into things of value, the soil conditioning agent can be obtained to improve soil, and economic benefits of a reconstituted tobacco enterprise can be improved.

Description

technical field [0001] The invention relates to the technical field of soil fertilizer preparation, in particular to a method for producing a saline-alkali soil conditioner by utilizing concentrated waste liquid of reconstituted tobacco leaves in a papermaking process. Background technique [0002] Paper-making reconstituted tobacco is a comprehensive utilization technology of tobacco waste in the world at present. Since this technology follows the techniques of plant natural extraction and separation, low-temperature concentration, and papermaking, a large amount of waste liquid is produced during the production process, which is harmful to the environment. And the production enterprises have brought serious troubles. Usually, more than 40-50 tons of waste liquid needs to be discharged for every ton of product produced. In addition to tobacco organic matter and tobacco short fiber, this production waste liquid also contains a large amount of calcium carbonate, ammonia nitro...
