Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, in particular to a dimethyl sulfoxide wastewater treatment device. Background Art

[0002] Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound with the molecular formula (CH3)2SO. It is a colorless, odorless, transparent liquid at room temperature and is hygroscopic and flammable. It is highly polar, has a high boiling point, is thermally stable, is aprotic, and is miscible with water. It is soluble in most organic compounds, including ethanol, propanol, benzene, and chloroform, earning it the nickname "universal solvent."

[0003] The production of dimethyl sulfoxide (DMSO) generates wastewater, which has poor biodegradability and is difficult to directly treat using conventional biological methods. Treatment methods for DMSO wastewater primarily include photocatalytic oxidation and biochemical methods. In the biochemical method, anaerobic degradation of DMSO by highly efficient bacteria produces a certain amount of sulfur-containing volatiles, causing secondary pollution. Aerobic degradation of DMSO also presents challenges such as long degradation times and low removal rates.

[0004] When using the existing photocatalytic method, a lamp is often installed on the top of the reaction tank. Therefore, it can only have a good catalytic effect on the surface of the wastewater, while the internal water receives less light and has a poor catalytic effect. Utility Model Content

[0008] When the present application is in use, dimethyl sulfoxide wastewater enters the wastewater treatment tank through the water inlet pipe, and then sodium hydroxide, hydrogen peroxide and ferrous sulfate are injected into the wastewater treatment tank and the water pump is started. The water pump draws the mixed water into the circulation pipe and flows down from the upper part of the wastewater treatment tank through the circulation pipe and falls on the corresponding transparent plate. Since a lamp tube is provided in the transparent plate, the mixed water can be better photocatalyzed, thereby accelerating the reaction and quickly removing the dimethyl sulfoxide in the dimethyl sulfoxide wastewater. The water pump circulates to pump up the mixed water and drop it from the transparent plate, which not only increases the contact time of the mixed water with light, so that all the mixed water can be illuminated by light, better realizing photocatalysis, but also can achieve better mixing of the various components in the mixed water.

[0009] Preferably, the opposite ends of the glass plate extend out of the wastewater treatment tank and are sealed at the exit. The glass plate is transversely provided with a groove, and a rectangular frame is slidably fitted within the groove. The lamp tubes are arranged in multiple rows and are detachably fixed within the rectangular frame. The rectangular frame slides within the groove, allowing for easy removal from the groove, thereby facilitating repair of damaged lamp tubes.

[0010] Preferably, the inner walls of both sides of the groove are provided with sliding grooves, the rectangular frame is slidably fitted in the sliding grooves, and the lamps located in the rectangular frame are connected in parallel. The parallel connection of the lamps ensures that even if one of the lamps is damaged, it will not affect the normal operation of the other lamps.

[0011] Preferably, the transparent plate includes a cleaning plate and a fixed plate, the fixed plate is fixedly arranged on the wastewater treatment tank, the cleaning plate is located in the wastewater treatment tank, the groove extends to the cleaning plate through the fixed plate, an annular plate is sleeved on the relative edges of the cleaning plate and the fixed plate, the opposite surfaces of the two annular plates are fixedly connected with a sealing gasket, the two annular plates are fixedly connected by bolts, the upper part of the wastewater treatment tank closes the lid, and the sodium hydroxide dosing pipe, the hydrogen peroxide dosing pipe, the ferrous sulfate dosing pipe and the water inlet pipe are arranged on the lid. When performing wastewater treatment, the lid is opened and the bolts are rotated to remove the cleaning plate from the fixed plate, thereby cleaning the cleaning plate, ensuring its transparent state, and facilitating better photocatalysis. The sealing gasket plays a sealing role to prevent water from entering through the gap between the cleaning plate and the fixed plate.

[0012] The beneficial effects of the present invention are as follows: the use of the present application can utilize a water pump to circulate water and flow it to the transparent plate to be illuminated, so that all mixed water can be illuminated, achieving a better catalytic effect and achieving better mixing of the various components in the mixed water.
