[0017] The outer wall of the temperature probe 14 is fixedly connected to the temperature control screen 3 through electric wires. The temperature probe 14 transmits the collected temperature data to the temperature control screen 3 via electric wires. The outer wall of the bottom of the waste liquid container 4 is fixedly connected to the temperature insulation and pressure bearing base 7. The outer wall of the temperature control screen 3 is fixedly connected to the outer wall of the waste liquid container 4. The top of the waste liquid container 4 is fixedly connected to a pressure-resistant and acid-resistant pipe 2.

[0018] The outer wall of the covered drainage pipe 6 is fixedly connected to the inner wall of the temperature-resistant layer 8, the top of the liquid distributor 13 is fixedly connected to the bottom of the filter 9, the filter 9 is used to filter out residual substances in the chemical waste liquid, the top of the pressure-resistant and acid-resistant pipeline 2 is slidably connected to the container cover 1, and the outer wall of the temperature control screen 3 is fixedly connected to the outer wall of the ultraviolet lamp 11 through an electric wire.

[0019] Working principle:

[0020] When in use, it is first necessary to slide out the container cover 1 on the pressure-resistant acid and alkali-resistant pipe 2 so that the cavity in the temperature-resistant layer 8 is connected to the outside world. Then the container cover 1 can be opened to allow the chemical waste liquid to flow into the waste liquid container 4 through the pressure-resistant acid and alkali-resistant pipe 2. The chemical waste liquid flowing into the pressure-resistant acid and alkali-resistant pipe 2 flows downward under the action of gravity and flows to the filter 9. The residual substances in the flowing chemical waste liquid are filtered through the filter 9. The anti-collision fixing bracket 5 around the waste liquid container 4 is used to prevent foreign objects from colliding with the waste liquid container 4, and the heat-insulating pressure-bearing base 7 at the bottom of the waste liquid container 4 is used to isolate the waste liquid container 4 from the influence of the external temperature.

[0021] The chemical waste liquid filtered by the filter 9 flows downward and flows to the liquid distributor 13. The chemical waste liquid filtered by the filter 9 enters the catalyst packing block 12 under the distribution of the liquid distributor 13, and the chemical waste liquid is catalyzed by the catalyst in the catalyst packing block 12. Then, the chemical waste liquid is pretreated by the ultraviolet light emitted by the ultraviolet lamp 11 in the quartz glass tube 10. After the pretreatment of the chemical waste liquid is completed, the cover on the covered drain pipe 6 can be opened, so that the pretreated chemical waste liquid can flow out to the outside through the covered drain pipe 6.

[0022] The irradiation of the ultraviolet lamp 11 will generate heat, causing the temperature in the temperature-resistant layer 8 to rise. The temperature probe 14 is used to detect the internal temperature of the temperature-resistant layer 8, and transmit the detected temperature data to the temperature control screen 3 in real time through the wire. After the staff observes that the temperature data displayed on the temperature control screen 3 is too high, the ultraviolet lamp 11 can be controlled to be turned off through the temperature control screen 3.
