[0002] Petrochemical industry is a processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. Petrochemical wastewater refers to the wastewater discharged by petrochemical plants. The composition of the wastewater is complex. Due to the large number of petrochemical products, the complex reaction processes and unit operations, the properties of the wastewater are complex and variable.

[0003] Petrochemical wastewater treatment equipment can employ physical, chemical, and biological treatment methods. However, most common petrochemical wastewater treatment devices suffer from low treatment intensity during use, making it inconvenient to simultaneously perform multiple treatments on wastewater, thus affecting treatment efficiency.

[0004] There is an urgent need for a wastewater treatment device for petrochemical production to address the technical deficiencies mentioned above. Utility Model Content

The chamber is equipped with an oil scraper. A first pump body is installed at the top of the partition chamber, a second pump body is installed at the top of the sedimentation chamber, a drive motor is installed at the top of the sedimentation chamber, a stirring shaft is installed at the output end of the drive motor, a coagulant storage tank is located on the right side of the drive motor, a filter screen is installed at the top of the detection chamber, filter paper is installed inside the filter screen, a detector is installed on the right side of the processing box, an infrared spectral probe is installed on the detector, a drain pipe is installed at the bottom right side of the processing box, and a sewage pipe is installed at the bottom of the sedimentation chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the wastewater treatment equipment for petrochemical production not only enhances the intensity of wastewater treatment and facilitates the detection of treated water quality, but also enables classified discharge.

[0015] (1) By setting up a partition chamber, oil scraper, track, oil scraper, drive motor, coagulant storage tank and stirring shaft, the sewage first enters the partition chamber for water and oil separation. The servo motor drives the oil scraper to rotate so that the oil scraper continuously scrapes off the upper layer of oil and water. Then the sewage enters the sedimentation chamber through the first pump body. The coagulant in the coagulant storage tank can enter the interior of the sedimentation chamber. The drive motor drives the stirring shaft to rotate so that the coagulant and sewage are fully mixed. Then, wait for the internal impurities to settle before proceeding with subsequent treatment. This structure can improve the intensity of sewage treatment and enhance the sewage treatment efficiency through double filtration.

[0016] (2) By setting up a filter screen, mounting slot, infrared spectral probe, detector and detection chamber, the sewage enters the detection chamber after treatment. The sewage is first filtered again through the filter screen and filter paper inside the detection chamber. The filtered sewage can be tested for water quality by the infrared spectral probe. Once the test is qualified, the drain pipe can be opened to drain water. Once the test is unqualified, the detector will alarm in time to remind the staff to clean and maintain the equipment. This structure realizes the functions of easy detection and treatment of water quality and easy alarm and cleaning in time.

[0017] (3) By setting up an oil collection box, an oil outlet, a drain pipe and a control valve, the sewage containing oil can first enter the interior of the partition chamber through the water inlet pipe. Due to the principle that oil and water do not mix, the sewage inside the partition chamber is driven by a servo motor to rotate the oil scraper. The oil scraper outside the oil scraper can hang the upper layer of oil from the oil outlet into the interior of the oil collection box. The oil is then discharged from the interior of the oil collection box. The impurities that have settled inside the sedimentation chamber can be discharged through the drain pipe. This structure realizes the function of easy classification and discharge of impurities. Attached Figure Description

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the servo motor 22 drives the oil scraper roller 6 to rotate, so that the oil scraper 8 continuously scrapes off the upper layer of oil and water. Then, the sewage enters the sedimentation chamber 21 through the first pump body 9. The coagulant in the coagulant storage tank 11 can enter the interior of the sedimentation chamber 21. The drive motor 10 drives the stirring shaft 12 to rotate, so that the coagulant and sewage are fully mixed.
