[0002] With the continuous expansion and rapid development of my country's chemical industry, not only economic efficiency is affected, but also the generation of chemical wastewater during production. In today's context of increasingly scarce water resources, uneven water distribution, and severe water pollution, environmental protection requirements and industrial water reuse rates are constantly rising. Therefore, researching how to improve the reuse rate of chemical wastewater is of great significance. In the wastewater treatment process, effectively removing ions that cause scaling on membrane elements before the wastewater enters the membrane treatment system, thereby improving the quality of the wastewater entering the system and delaying the scaling and fouling cycle of the membrane elements, has become an urgent problem to be solved in this field. Therefore, we need a certain wastewater pretreatment operation, and thus we designed a wastewater pretreatment device for fine chemical industries. Utility Model Content

[0010] Compared with related technologies, the wastewater pretreatment device for fine chemical industry provided by this utility model has the following beneficial effects:

[0011] 1. This utility model provides a wastewater pretreatment device for fine chemical industry. Wastewater to be treated is added to the wastewater treatment cylinder via a wastewater addition pipe. Simultaneously, a cleaning agent addition pipe is used to add and mix the cleaning liquid. The mixture is stirred and mixed inside the wastewater treatment cylinder. After a certain mixing time, a control valve directly controls the opening of the transmission pipe. The wastewater and flocculants directly enter the pre-storage cylinder through the collection pipe. The flocculants are filtered through a flocculant filter screen. Finally, the treated water is transferred to the wastewater detection cylinder through a water transmission pipe. A detection controller on the wastewater detection cylinder monitors the water quality. If the water does not meet discharge standards, a circulation pump draws the liquid from the wastewater detection cylinder back into the wastewater treatment cylinder, and cleaning liquid is added again for mixing, achieving the treatment effect once more.

[0012] 2. This utility model provides a wastewater pretreatment device for fine chemical industry. The stirring inside the wastewater treatment cylinder is controlled by a stirring motor that directly controls the rotation of the stirring power shaft, driving the metal stirring rod to stir the materials, thus accelerating the mixing efficiency. The control setting panel on the detection controller can set the peak value of the detection value. Once the detected data is higher than the peak value, the detection controller will automatically control the start of the circulation pump to achieve circulation treatment through the circulation transmission pipe. When the value is lower than the peak value, the circulation pump will not start, and the treated water is directly stored inside the wastewater detection cylinder, improving the intelligent use effect of the device and increasing its ease of use.

[0024] Working principle:

[0025] Wastewater to be treated is added to the wastewater treatment tank 1 via wastewater addition pipe 2. Simultaneously, cleaning liquid is added and mixed via detergent addition pipe 3. The mixture is stirred and mixed inside the wastewater treatment tank 1. After mixing for a period of time, the control valve 5 directly controls the opening of the transmission pipe 4. The wastewater and flocculants will directly enter the pre-storage tank 7 through the collection pipe 6. The flocculants are filtered by the flocculant filter screen 19. Finally, the treated water is transferred to the wastewater detection tank 9 through the water transmission pipe 8. The detection controller 10 on the wastewater detection tank 9 is used to detect the water. If the water does not meet the discharge standards, the liquid inside the wastewater detection tank 9 is pumped back into the wastewater treatment tank 1 by the circulation pump 11. Cleaning liquid is added and mixed again to achieve the treatment effect.

[0026] The stirring inside the wastewater treatment cylinder 1 is controlled by the stirring motor 15, which directly controls the rotation of the stirring power shaft 16. This drives the metal stirring rod 18 to stir the materials, accelerating the mixing efficiency. The control setting panel 21 on the detection controller 10 can set the peak value of the detection. Once the detected data is higher than the peak value, the detection controller 10 will automatically control the circulation pump 11 to start, and use the circulation transmission pipe 12 to achieve circulation processing. When the data is lower than the peak value, the circulation pump 11 will not start, and the treated water is directly stored inside the wastewater detection cylinder 9, improving the intelligent use effect of the device and increasing its ease of use.
