Embodiment 1

[0091] 1. Recycle the water for cultivating mung bean sprouts and put it in the recycling water tank.

[0092]2. Combined disinfection of recycled water through ultraviolet / ozone combined equipment, controlling the irradiation dose of ultraviolet rays to 12MJ / cm 2 , the concentration of ozone in recycled water is 2mg / L.

[0093] 3. Pass the water into the quartz sand filter equipment for filtration. The quartz sand layer is composed of quartz sand with a particle size of 1.2-2.4mm and a thickness of 500mm. Then through the activated carbon filter equipment, the activated carbon layer is composed of an activated carbon filter material layer with a particle size of 0.6-2.75mm and a thickness of 700mm and an activated carbon layer with a particle size of 3-8mm and a thickness of 700mm. Control the initial filtration rate of the quartz sand filter equipment to be 8m / h. Filtration is completed to obtain purified water.

Embodiment 2

[0095] 1. Recycle the water for cultivating mung bean sprouts and put it in the recycling water tank.

[0096] 2. Combined disinfection of recycled water through ultraviolet / ozone combined equipment, controlling the irradiation dose of ultraviolet rays to 140MJ / cm 2 , the concentration of ozone in recycled water is 0.4mg / L.

[0097] 3. Pass the water into the quartz sand filter equipment for filtration. The quartz sand layer is composed of quartz sand with a particle size of 1.2-2.4mm and a thickness of 500mm. Then through the activated carbon filter equipment, the activated carbon layer is composed of an activated carbon filter material layer with a particle size of 0.6-2.75mm and a thickness of 700mm and an activated carbon layer with a particle size of 3-8mm and a thickness of 700mm. Control the initial filtration rate of the quartz sand filter equipment to be 15m / h. Filtration is completed to obtain purified water.

Embodiment 3

[0099] 1. Recycle the water for cultivating mung bean sprouts and put it in the recycling water tank.

[0100] 2. Combined disinfection of recycled water through ultraviolet / ozone combined equipment, controlling the irradiation dose of ultraviolet rays to 40MJ / cm 2 , the concentration of ozone in recycled water is 1.2mg / L.

[0101] 3. Pass the water into the quartz sand filter equipment for filtration. The quartz sand layer is composed of quartz sand with a particle size of 1.2-2.4mm and a thickness of 500mm. Then through the activated carbon filter equipment, the activated carbon layer is composed of an activated carbon filter material layer with a particle size of 0.6-2.75mm and a thickness of 700mm and an activated carbon layer with a particle size of 3-8mm and a thickness of 700mm. Control the initial filtration rate of the quartz sand filter equipment to be 12m / h. Filtration is completed to obtain purified water.

Abstract

The invention relates to the field of vegetable culture, and discloses a water circulation use method for bean sprout culture. The method comprises the following steps of S1, performing combined sterilization on recycled water through ultraviolet ray / ozone, wherein the recycled water is water for culturing mung bean sprout; S2, sequentially passing the recycled water sterilized in the step S1 through quartz sand and active carbon to be filtered for obtaining pure water used for culturing soybean sprout. When the pure water obtained by the method is used for culturing the soybean sprout in a circulation way, the quality of the soybean sprout cannot be lowered.

Description

technical field [0001] The invention relates to the field of vegetable cultivation, in particular to a water recycling method for bean sprout cultivation. Background technique [0002] The cultivation of bean sprouts requires a large amount of water to achieve the purpose of adjusting the growth temperature of bean sprouts, replenishing the water required for bean sprout growth, and eliminating microorganisms such as bacteria and mold. At present, in order to save water resources and reduce production costs, most of the enterprises that produce bean sprouts on a large scale will recycle the water after recycling. Circulating water contains a large amount of organic matter, mainly secondary metabolites secreted during the growth of bean sprouts, and some secretions from bacteria. Circulating water also contains bacterial molds. These substances inhibit the normal growth of bean sprouts to a certain extent and affect the quality of bean sprouts. quality. [0003] Li Yonghua ...
