Problems solved by technology

[0004] For example, the authorized notification number is CN 104671330B, which discloses a dynamic photocatalytic wastewater treatment device, which can effectively treat organic wastewater through the action of light and catalyst, but in the process of treatment, the light used cannot fully irradiate Into the organic wastewater of the catalyst, so that it can quickly carry out photocatalysis, and at the same time, the photocatalysis is not sufficient, and there is still a lot of wastewater in the reaction wastewater that has not been treated by photocatalysis

Embodiment 1

[0039] figure 1 , figure 2 and image 3 A kind of circulation type waste water photocatalytic treatment device shown, comprises primary treatment box 1 and circulation treatment box 4, and described primary treatment box 1 and circulation treatment box 4 are communicated through connecting pipeline 7; figure 2 The shown primary treatment box 1 includes a treatment box body 101, the upper end of the treatment box body 101 is provided with an organic waste water inlet 102, and the organic waste water used for treatment enters the treatment box body 101 through the organic waste water inlet, and the organic waste water after treatment enters the treatment box body 101. The waste water enters the connection pipeline 7 through the treatment product outlet 103, and is transported to the circulation treatment tank 4 through the connection pipeline 7. A delivery pump can be connected to the connection pipeline 7, which can speed up the delivery efficiency of the treated waste water...

Embodiment 2

[0045] On the basis of Embodiment 1, in order to ensure that when the light source assembly 2 is driven by the rotating biaxial motor, the light emitted covers the entire treatment box as much as possible, and photocatalyzes with the organic wastewater in the treatment box under the action of the catalyst. role, such as Figure 4 The light source assembly 2 includes a light insulation tube 202 fixedly connected to the biaxial motor 107, and a catalytic light source 201 movably connected to the top of the light insulation tube 202. The light insulation tube 202 is provided with a plurality of transparent Light component 203, and this light-transmitting component 203 is perpendicular to described light-proof tube 202, and the position that light-transmitting component 203 and light-proof tube 202 are connected in described light-proof tube 202 is provided with reflective component 204, and described light-proof component 204 The ultraviolet light emitted by the catalytic light s...

Embodiment 3

[0050] On the basis of Example 1 and Example 2, as Figure 7 The lower part of the primary treatment box 1 is fixed with a sealing partition 105 , and a driving shaft of the biaxial motor 107 passes through the middle of the sealing partition 105 and is fixedly connected with the lower part of the light source assembly 2 . Sealing partitions are used to seal and separate the two-axis motor 107 to fully protect them;

[0051] Such as Figure 5 , Figure 6 The catalyst rotary spraying assembly 3 includes an annular pipe 301 arranged at the lower end of the sealing partition 105, and the annular pipe 301 is provided with a plurality of nozzle pipes 302 perpendicular to the annular surface formed by the annular pipe 301, such as Figure 7 The sealing partition 105 is movably connected with an annular plate 106 concentric with the sealing partition 105, and the annular plate 106 rotates relative to the sealing partition 105, a plurality of nozzles 302 extend through the annular p...

Abstract

The invention relates to a circulating photocatalytic treatment device for wastewater, comprising a primary treatment box and a circulation treatment box, a catalyst rotary spray assembly is provided at the bottom of the primary treatment box, a light source assembly is provided in the middle of the primary treatment box, and the catalyst The rotating spraying assembly and the light source assembly are respectively fixedly connected to the biaxial shafts of the biaxial motors located at the bottom of the primary treatment box, and the said biaxial motors drive the light source assembly and the catalyst rotary spraying assembly to rotate in the primary processing box respectively; cyclic processing There is a solid-liquid separation component inside the tank. The liquid outlet at the bottom of the circulation treatment tank is connected to a liquid return treatment pipeline. The other end of the liquid return treatment pipeline is connected to the upper part of the circulation treatment tank. Processing component; the light source component can form an aperture in the process of rotation, fully provide light for photocatalysis, and at the same time fully stir organic wastewater and catalysts to speed up the efficiency of photocatalysis.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a circulating photocatalytic treatment device for waste water. Background technique [0002] With the rapid development of my country's economy, environmental problems are becoming more and more serious, especially a large amount of organic wastewater has brought great challenges to the environment. The high concentration of organic wastewater will harm the aquatic ecosystem, lead to the deterioration of water quality, and also have a great impact on the lives of the surrounding residents. Organic wastewater contains a large amount of toxic and refractory organic matter, which accumulates and enriches in water, soil and other natural environments, and finally enters the human body through the food chain, endangering human health. Therefore, a series of environmental problems caused by organic wastewater have attracted great attention. However, as we all know, ...
