Description

Technical Field

[0001] This utility model relates to the technical field of industrial wastewater treatment devices, specifically a wastewater treatment device containing tetrahydrofuran. Background Technology

[0002] Tetrahydrofuran is a colorless, transparent organic liquid with an ether-like odor. It exhibits good flowability and solubility, dissolving all compounds except polyethylene, polypropylene, and fluoropolymers, particularly polyvinyl chloride, polyvinylidene chloride, and styrene-butadiene rubber. Chemically, tetrahydrofuran is a heterocyclic compound, a fully hydrogenated product of the aromatic compound furan.

[0003] Tetrahydrofuran-containing wastewater refers to industrial wastewater containing tetrahydrofuran. Tetrahydrofuran is an important organic chemical raw material with advantages such as low toxicity, low boiling point, and good fluidity. It is widely used in reactive solvents and synthetic resins. However, with the increase in its usage, the treatment of tetrahydrofuran-containing wastewater has become increasingly prominent. Its treatment requires the addition of certain additives to precipitate impurities in the wastewater. However, because the reaction between the additives and the wastewater is slow, the additives are discharged before fully reacting with the wastewater, resulting in a high content of impurities in the discharged wastewater and reducing the wastewater treatment efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a tetrahydrofuran-containing wastewater treatment device to solve the problem mentioned in the background art that existing wastewater contains a large amount of pollutants that cannot be directly discharged. It is necessary to add certain additives to the wastewater to precipitate the impurities. However, because the reaction between the additives and the wastewater is slow, the additives are discharged before fully reacting with the wastewater, resulting in a large amount of impurities in the discharged wastewater and reducing the wastewater treatment efficiency. To achieve the above objectives, this utility model provides the following technical solution: a tetrahydrofuran-containing wastewater treatment device, comprising a treatment tank, with an inlet pipe fixedly connected to the top of the treatment tank, and a reaction assembly inside the treatment tank.

[0008] In a further preferred embodiment, a detection block is installed inside the purification tank, and a display is fixedly connected to one side of the purification tank. The detection block is electrically connected to the display, and an indicator light is fixedly connected to one side of the display.

During use, the reaction state inside the treatment tank can be observed through the observation window 23 to ensure the effect of the reaction.

[0032] Working principle:

[0033] Wastewater enters the treatment tank 1 through the inlet pipe 2. Additives from the additive tank 4 are added to the treatment tank 1 through the connecting pipe 5. The wastewater inside the tank then reacts with the reaction assembly 3. Starting the motor 305 causes the rotating rod 303 to rotate, which in turn drives the stirring rod 304 to agitate the wastewater. Simultaneously, impurities in the wastewater are adsorbed into the filter screen 307 as flocculent matter is generated during the reaction. After the reaction, the wastewater is discharged from the treatment tank 1 through the drain pipe 11. Impurities and sediments in the wastewater accumulate inside the treatment tank 1 through the mesh tray 7, while a small amount of sediment is also filtered and adsorbed by the activated carbon layer 20 inside the pipe. The filtered water is discharged into the purification tank 12 through the installation pipe 22 connected to the connector 21, and is purified by the purification component 13. The disinfection lamp group 1303 in the purification component 13 is turned on to disinfect the water inside the purification tank 12, and the water index is detected by the detection block 14 in the purification tank 12 and displayed on the display 15. When the water inside the purification tank 12 meets the discharge standard, the display light 16 lights up, the purification component 13 is turned off, and the water is discharged through the discharge pipe 17. At the same time, after the wastewater inside the tank is discharged, the impurities and sediments contained in the water accumulate inside the treatment tank 1. The screw pump 9 is started, and the sewage pipe 10 connected to the screw pump 9 discharges the impurities contained inside the tank.

[0034] The method of use and advantages of this utility model: The working process of this tetrahydrofuran-containing wastewater treatment device is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, during use, wastewater enters the treatment tank 1 through the inlet pipe 2. The additive box 4 adds the additives inside the tank into the treatment tank 1 through the connecting pipe 5. Then, the wastewater inside the tank reacts through the reaction component 3. By starting the motor 305, the rotating rod 303 rotates through the transmission end of the motor 305, driving the stirring rod 304 to stir the wastewater inside the tank. At the same time, the impurities in the wastewater are adsorbed into the filter screen 307 during the reaction as flocculent matter is generated. After the reaction, the wastewater inside the treatment tank 1 is discharged from the tank through the drain pipe 11. The impurities and sediments in the wastewater accumulate inside the treatment tank 1 through the mesh tray 7. At the same time, a small amount of sediment in the wastewater also passes through the activated carbon layer 20 inside the pipe. After filtration and adsorption, the filtered water is discharged into the purification tank 12 through the installation pipe 22 connected to the connector 21. It is then purified by the purification component 13. The disinfection lamp group 1303 in the purification component 13 is turned on to disinfect the water source inside the purification tank 12. The water index is detected by the detection block 14 in the purification tank 12 and displayed on the display 15. When the water source inside the purification tank 12 meets the discharge standard, the display light 16 lights up, the purification component 13 is turned off, and the water source is discharged through the discharge pipe 17. At the same time, after the wastewater inside the tank is discharged, the impurities and sediments contained in the water accumulate inside the treatment tank 1. The screw pump 9 is started, and the sewage pipe 10 connected to the screw pump 9 discharges the impurities contained inside the tank.
