Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a laboratory wastewater treatment device. Background Technology

[0002] The laboratory generates a lot of experimental wastewater, which contains many solid particulate impurities and may also contain microorganisms such as bacteria and viruses. It needs to be purified before it can be discharged, otherwise it will cause pollution to the outside world.

[0003] Existing laboratory wastewater treatment devices typically perform single-pass filtration to remove solid particulate impurities. If the wastewater contains a large amount of impurities, a single pass is insufficient to completely remove them. Furthermore, existing devices often disinfect wastewater by directly pouring disinfectant into it, resulting in inadequate mixing and insufficient elimination of bacteria, viruses, and other microorganisms. Therefore, there is an urgent need to develop a laboratory wastewater treatment device that utilizes circulating filtration to thoroughly remove particulate impurities, ensures thorough mixing of wastewater and disinfectant, and employs ultraviolet-assisted disinfection to effectively kill bacteria, viruses, and other microorganisms. This would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a laboratory wastewater treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laboratory wastewater treatment device includes a treatment tank, a mixing mechanism, a circulation mechanism, a filter screen, a support plate, an activated carbon layer, a transparent isolation cover, and a UV lamp. The filter screen is fixed inside the treatment tank, and a support plate is fixed to the lower side of the filter screen within the treatment tank. The support plate has multiple drainage holes, and the activated carbon layer is supported on the upper side of the support plate. A circulation mechanism connected to one side of the treatment tank is installed. The circulation mechanism includes a circulation pump, a suction pipe, and a drain pipe. The circulation pump is fixed to the side of the treatment tank, with its inlet end connected to the suction pipe and its outlet end connected to the drain pipe. A mixing mechanism extending into the bottom of the treatment tank is installed. Two transparent isolation covers are installed in the lower half of the interior of the treatment tank, and a UV lamp is installed inside each of the transparent isolation covers.

[0007] Preferably, the connection between the water suction pipe and the treatment box is located below the support plate, and the connection between the drain pipe and the treatment box is located above the filter screen.

[0008] Preferably, the mixing mechanism includes a drive motor, a first gear, a second gear, and a stirring shaft. The drive motor is fixed to the bottom of the processing box, and the first gear is fixed on the output shaft of the drive motor. A second gear is provided on one side of the first gear to mesh with it. The second gear is fixed on the stirring shaft, and the stirring shaft is rotatably connected to the processing box.

[0009] Preferably, the top of the treatment tank is provided with a water inlet, the bottom of the treatment tank is provided with a water outlet pipe, and a valve is installed on the water outlet pipe.

[0010] Preferably, a maintenance plate is detachably installed on one side of the processing box.

[0011] The beneficial effects of this utility model are as follows: When using this laboratory wastewater treatment device, the valve is closed, and laboratory wastewater is added through the inlet. The wastewater flows downwards, passing through a filter screen and an activated carbon layer. Large particulate impurities are filtered out by the filter screen, and small particulate impurities are filtered out by the activated carbon layer. Simultaneously, a circulating pump draws wastewater from below the support plate and transports it above the filter screen, allowing for multiple filtrations to thoroughly remove solid impurities. Disinfectant is then added through the inlet and mixed with the wastewater. A drive motor rotates the first gear, the second gear, and the stirring shaft, which stirs and mixes the wastewater and disinfectant for more thorough disinfection. Simultaneously, ultraviolet light is activated to irradiate and disinfect the wastewater, completely killing bacteria, viruses, and other microorganisms. Finally, the valve is opened, and the wastewater is discharged. In summary, this utility model circulates and filters wastewater, thoroughly removing particulate impurities; it thoroughly mixes wastewater and disinfectant, and uses ultraviolet light for disinfection to effectively kill bacteria, viruses, and other microorganisms.

Large particles are filtered out by the filter screen 5, and small particles are filtered out by the activated carbon layer 7. Simultaneously, a circulating pump 401 draws wastewater from below the support plate 6 and transports it above the filter screen 5 for multiple filtrations, thoroughly removing solid impurities. Disinfectant is added through inlet 101 and mixed with the wastewater. The mixing mechanism 3 stirs and mixes the wastewater and disinfectant for more thorough disinfection.

[0024] Working principle: When using this laboratory wastewater treatment device, close valve 103, then add laboratory wastewater through inlet 101. The wastewater flows downwards, passing through filter screen 5 and activated carbon layer 7. Large particulate impurities in the wastewater are filtered out by filter screen 5, and small particulate impurities are filtered out by activated carbon layer 7. At the same time, the circulating pump 401 draws wastewater from below support plate 6 and transports it above filter screen 5 for multiple filtrations, thus thoroughly removing solid impurities from the wastewater. Then, disinfectant is added through inlet 101 and mixed with the wastewater. The drive motor 301 drives the first gear 302, the second gear 303, and the stirring shaft 304 to rotate. The stirring shaft 304 stirs and mixes the wastewater and disinfectant for more thorough disinfection.
