Embodiment 1

[0038] Such as figure 1 The device shown includes: a micro-nano bubble generating device 1, a photocatalytic disinfection device 2, a nitrification reaction device 3, a regulating tank 4, a soilless cultivation bed 5, an ultraviolet lamp 21, an aeration head 23, and the like.

[0039] The air source 7 and the water source 8 respectively enter the micro-nano-bubble generating device 1 through the air source interface and the liquid interface of the micro-nano-bubble generating device 1, and are fully mixed inside the device to form a gas-liquid mixed fluid, and one end of the gas-liquid mixed fluid pipeline 9 is connected to One end of the gas-liquid mixed fluid outlet of the micro-nano bubble generating device is connected to the aeration head 23 at the bottom of the photocatalytic disinfection device 2 . The gas-liquid mixed fluid formed in the micro-nano-bubble generating device 1 passes through the gas-liquid mixed fluid pipeline 9 and the aeration head 23 to form micro-nan...

Embodiment 2

[0041] Such as Figure 6 The device shown includes: a micro-nano bubble generating device 1, a photocatalytic disinfection device 2, a regulating tank 4, an ultraviolet lamp 21, an aeration head 23, an irrigation device 51, and the like.

[0042] The air source 7 and the water source 8 respectively enter the micro-nano-bubble generating device 1 through the air source interface and the liquid interface of the micro-nano-bubble generating device 1, and are fully mixed inside the device to form a gas-liquid mixed fluid, and one end of the gas-liquid mixed fluid pipeline 9 is connected to One end of the gas-liquid mixed fluid outlet of the micro-nano bubble generating device is connected to the aeration head 23 at the bottom of the photocatalytic disinfection device 2 . The gas-liquid mixed fluid formed in the micro-nano-bubble generating device 1 passes through the gas-liquid mixed fluid pipeline 9 and the aeration head 23 to form micro-nano-bubble water and enters the photocata...

Embodiment 3

[0044] On the basis of Example 1 or Example 2, the photocatalytic disinfection device 2 includes: a photocatalytic pool 26, an ultraviolet lamp 21 positioned in the photocatalytic pool 26, a catalyst carrier grid 22 and a catalyst carrier grid 22 attached to The photocatalyst on the catalyst carrier grid 22 and the ultraviolet lamp 21 are alternately arranged, and the aeration head 23 is located in the photocatalytic pool 26 and below the catalyst carrier grid 22 and the ultraviolet lamp 21 .

[0045] The catalyst carrier grid 22 is made of at least one of porous glass, glass fiber, glass plate and metal.

Abstract

The invention relates to a photocatalytic aerated disinfecting and fertilizer supplementing device which comprises a micro-nano bubble generating device, a photocatalytic disinfection device, a nitration reaction device, a regulating reservoir and an aerator, wherein the micro-nano bubble generating device is communicated with the aerator; the outlet of the photocatalytic disinfection device is communicated with the inlet of the regulating reservoir; the outlet of the photocatalytic disinfection device is communicated with the inlet of the nitration reaction device; and the outlet of the nitration reaction device is communicated with the inlet of the regulating reservoir. According to the device disclosed by the invention, air can be rapidly dispersed in a liquid phase in a micro-nano bubble form, the dissolved oxygen value in a water body is improved, the conversion efficiency of a subsequent nitration reaction is improved, growth of the plant root system can be promoted, and particularly for hydroponic plants in soilless culture, the root rot phenomenon caused by oxygen lack of the root system can be avoided.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a device and method for photocatalytic oxygenation, disinfection and fertilization in the water and fertilizer integration technology. Background technique [0002] The use of chemical fertilizers and pesticides has had a significant and far-reaching impact on the survival and development of human beings. Their use has greatly promoted the increase in crop production and income, solved the problem of food and clothing for human beings, enhanced social stability, and made great contributions to human health and the development of civilization. However, due to excessive use and abuse, environmental pollution, ecological structure damage, and food safety problems have become increasingly prominent. It is an inevitable trend of agricultural development to adopt advanced technology and production mode to ensure the efficient use of resources, reduce the use of chemical fertilize...
