detailed description

Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the utility model, rather than limiting the protection scope of the utility model.

As shown in Figure 1, the ultraviolet light-ozone catalytic oxidation sewage treatment device includes a pool body 1 and an ozone gas delivery pipe 8, the bottom of the pool body 1 is provided with a water inlet pipe 10, the top of the pool body 1 is provided with an outlet pipe 11, and an ozone gas delivery pipe 8 The dissolved air pump 9 communicates with the bottom of the pool body 1, and the pool body 1 is provided with a first filter layer, a second filter layer, a third filter layer, and a fourth filter layer in sequence from bottom to top; the first filter layer is ozone oxidation Catalytic bed 2, the second filter layer includes filter plate 3 and the aeration head 4 that is arranged on the upper side of filter plate 3, and aeration head 4 is communicated with ozone gas delivery pipe 8, and the 3rd filter layer includes activated carbon layer 5, activated carbon layer 5 The surface is coated with an ultraviolet oxidation catalyst. In this embodiment, the ultraviolet oxidation catalyst is titanium dioxide, and an ultraviolet lamp 6 is arranged around the activated carbon layer. The fourth filter layer is a biological filter area 7, that is, the area above the activated carbon layer.

As a further improvement of the utility model, the activated carbon layer 5 is protruding, and the raised part faces the water inlet direction. Such a structure can increase the contact area between the sewage and the activated carbon, thereby making the contact reaction between the sewage and the ultraviolet light oxidation catalyst more sufficient, and further improving Wastewater treatment efficiency.

When using the sewage treatment device, the sewage first enters the bottom of the pool body through the water inlet pipe. At this time, the ozone is dissolved in the sewage through the container pump, and the sewage dissolved in ozone flows through the ozone oxidation catalytic bed for the first treatment, and then the sewage flows through the second stage. The second filter layer is sterilized and oxidized again, and finally the sewage flows through the third filter layer, where the activated carbon can filter the larger particles in the sewage, and at the same time, the ultraviolet oxidation catalyst sterilizes the sewage again under the irradiation of ultraviolet light And redox treatment, and finally the sewage is filtered by the biological filtration area and discharged.

The utility model ultraviolet light-ozone catalytic oxidation sewage treatment device, the sewage is filtered through four filter layers, and the filtering effect is good. Extermination, oxidation, reduction, and good water treatment effect. The water treatment device is carried out in a pool body, and the treatment cost is low.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation.
