Embodiment 1

[0029] Weigh 0.6g of fresh gibberellin fermentation bacteria residue, add it to a 50ml high-pressure stirring reaction kettle, add 30ml of pure water, cover the kettle lid, and seal the kettle lid; heat to a set temperature of 125°C at 2°C / min, and add 30ml of pure water. The set temperature was maintained for 0.5h; after the reaction was over, the heating mantle of the reactor was removed, and a fan was used to cool it to room temperature. Open the valve to release the air pressure, open the lid of the kettle, separate the reacted material from solid and liquid, collect the separated liquid phase hydrothermal treatment liquid, and the solid phase filter residue can be used as soil fertilizer. The hydrothermal treatment solution was separated by a centrifuge (4000 r / min, centrifugation for 5 min), and the supernatant was taken for detection.

[0030] The supernatant of the hydrothermal treatment solution of the present embodiment is detected, and the detection results are as f...

Embodiment 2

[0033] Weigh 0.8 g of the dried gibberellin fermentation bacteria residue, add it to a 50 ml high-pressure stirring reaction kettle, add 30 ml of pure water (adjust the pH value to 10.8 with sodium carbonate), cover the kettle lid, and seal the kettle lid; Min heating to the set temperature of 125 ° C, and maintain the set temperature for 0.5h; after the reaction is completed, remove the heating jacket of the reactor, and use a fan to cool it to room temperature. Open the valve to release the air pressure, open the lid of the kettle, and conduct solid-liquid separation of the reacted materials. The solid-phase filter residue can be used as soil fertilizer, etc., and the separated liquid-phase hydrothermal treatment liquid is collected. The hydrothermal treatment solution was separated by a centrifuge (4000 r / min, centrifugation for 5 min), and the supernatant was taken for detection.

Embodiment 3

[0037]Weigh 1 g of the dried gibberellin fermentation bacteria residue, add it to a 50ml high-pressure stirring reaction kettle, add 30ml of purified water (adjust the pH value to 10.8 with sodium carbonate), cover the kettle lid, and seal the kettle lid; at 2°C / min Heating to the set temperature of 125°C, and maintaining the set temperature for 0.5 h; after the reaction is over, remove the heating jacket of the reactor, and cool it to room temperature with a fan. Open the valve to release the air pressure, open the lid of the kettle, and conduct solid-liquid separation of the reacted materials. The solid-phase filter residue can be used as soil fertilizer, etc., and the separated liquid-phase hydrothermal treatment liquid is collected. The hydrothermal treatment solution was separated by a centrifuge (4000 r / min, centrifugation for 5 min), and the supernatant was taken for detection.

Abstract

The invention discloses a detoxification treatment method of gibberellin fermentation bacteria residue, and solves the problem that the gibberellin fermentation bacteria residue is difficult to treat.The method includes detoxification treatment on gibberellin fermentation bacteria residue by using a hydrothermal method and comprises the following steps: 1) putting the gibberellin fermentation bacteria residue into a reaction kettle, then adding water, water and H2O2 or water and a surfactant into the reaction kettle, and finally, uniformly mixing the components; 2) sealing the reaction kettlefilled with the materials, and carrying out detoxification treatment on the gibberellin fermentation bacteria residues by utilizing a hydrothermal method under the conditions of heating and stirring;3) after the reaction is finished, cooling the reaction kettle, opening the valve of the reaction kettle to release air pressure after the reaction kettle is cooled, then opening the reaction kettle,carrying out solid-liquid separation on the reacted material, directly discharging one part of the liquid-phase hydrothermal treatment liquid, and recycling the other part of the liquid-phase hydrothermal treatment liquid, and recycling solid-phase filter residues for use. The method has the characteristics of high detoxification efficiency and environmental protection.

Description

technical field [0001] The invention relates to the technical field of fermentation bacteria residue treatment, in particular to a detoxification treatment method for gibberellin fermentation bacteria residue. Background technique [0002] Gibberellin, is a class of tetracyclic diterpene acids, the chemical name is 2,4-a-hydroxy-1-methyl-gibberellin-1,10-dicarboxylic acid-1,4a-lactone, it The basic structure is carbogiramane. It is a highly potent plant growth stimulant, which can promote the elongation of cells and stems, increase plant height, promote the growth of genetic dwarf plants, and promote the growth of physiological or viral dwarf plants; break certain vegetable seeds , tubers and bulbs and other organs dormancy, improve the germination rate, play the role of low-temperature vernalization and long-day sunshine, promote and induce the flowering of long-day vegetables; [0003] my country is the world's largest producer of gibberellin, accounting for more than 90...
