[0002] Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains various metals such as lead and cadmium; wastewater from the electroplating industry contains various heavy metals such as cyanide and chromium; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Because industrial wastewater often contains multiple toxic substances, it pollutes the environment and poses a significant threat to human health. Therefore, it is essential to develop comprehensive utilization methods to turn harm into benefit, and to implement appropriate purification measures based on the composition and concentration of pollutants in the wastewater before it can be discharged.

[0003] Existing wastewater treatment equipment generates a lot of sludge and residue during operation. The sludge and residue that accumulate at the bottom of the wastewater treatment tank are difficult to remove without external force, which can cause blockages in the tank. Furthermore, existing equipment is not convenient for oil removal, which affects the effectiveness of wastewater treatment.

[0004] Based on this, a high-efficiency water treatment device integrating sewage and oil removal is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, an integrated high-efficiency water treatment device for removing dirt and oil includes a frame 1, a workbench 2 on the frame 1, and a step 3 between the workbench 2 and the bottom surface of the frame 1. An integrated treatment tank 31 is installed on the workbench 2. The integrated treatment tank 31 contains a sedimentation zone 10, an oil removal zone 11, and a purification zone 12. A pretreatment tank 4 is installed on one side of the frame 1, containing a dirt removal mechanism. An agitation mechanism is installed at the top of the oil removal zone 11, and a purification mechanism is installed in the purification zone 12. The pretreatment tank 4 can perform preliminary filtration of sewage to avoid equipment blockage. The sedimentation zone 10 can allow heavier particulate matter such as mud and clay in the sewage to settle to the bottom of the tank, forming sludge, which is discharged periodically. The oil removal zone 11 uses an agitation device to oxidize and decompose oil in the sewage into harmless substances. The purification zone 12 can remove dissolved organic matter, heavy metal ions, and other harmful substances from the sewage, so that the treated water meets the discharge standards or reuse requirements.

[0026] In one embodiment, such as Figure 5As shown, the sludge removal mechanism includes a coarse screen 6, which is located inside the pretreatment tank 4. A fine screen 7 is installed below the coarse screen 6, and an inlet 5 is installed at the top of the pretreatment tank 4. The coarse screen 6 can intercept larger floating and suspended objects in the sewage, such as branches and plastic bottles, to prevent these large particles from entering the subsequent treatment units and avoid equipment blockage and damage. The fine screen 7 further removes smaller suspended objects and impurities, so that the sewage is initially purified.

[0027] In one embodiment, such as Figure 1 As shown, a first door 8 is provided on one side of the pretreatment box 4 at the position corresponding to the coarse screen 6, and a second door 9 is provided on one side of the pretreatment box 4 at the position corresponding to the fine screen 7. The doors can be opened to clean the coarse screen 6 and the fine screen 7.

[0028] In one embodiment, such as Figure 2 As shown, a first water pump 13 is installed on one side of the frame 1. The input end of the first water pump 13 is connected to the pretreatment tank 4 through the first connecting pipe 14, and the output end of the first water pump 13 is connected to the top of the sedimentation zone 10 through the second connecting pipe 15. Starting the first water pump 13 can inject the sewage in the pretreatment tank 4 into the sedimentation zone 10.

[0029] In one embodiment, such as Figure 1 As shown, a second water pump 22 is installed on one side of the frame 1. The input end of the second water pump 22 is connected to the sedimentation zone 10 through the third connecting pipe 23, and the output end of the second water pump 22 is connected to the oil removal zone 11 through the fourth connecting pipe 24. Starting the second water pump 22 can inject the sewage in the sedimentation zone 10 into the oil removal zone 11.

[0030] In one embodiment, such as Figure 3 and Figure 4 As shown, the stirring mechanism includes a support frame 16, which is located at the top of the oil removal zone 11. A motor 17 is installed on the support frame 16, and a rotating shaft 18 is installed at the output end of the motor 17. Several stirring blades 19 are installed on the rotating shaft 18. When an oxidant is injected into the oil removal zone 11, the motor 17 is started to drive the stirring blades 19 to stir the wastewater, so that it is fully mixed and reacted, and the oil is oxidized and decomposed into harmless substances.

[0031] In one embodiment, such as Figure 3 and Figure 4 As shown, the purification mechanism includes an ultrafiltration membrane 21, and several ultrafiltration membranes 21 are arranged sequentially in the purification zone 12. An electric valve 20 is installed between the bottom of the purification zone 12 and the oil removal zone 11.

The third water pump 27 can inject the purified water into the water storage tank 26 for storage.

[0033] Working Principle: During operation, wastewater first enters the pretreatment tank 4 through inlet 5, passing through the coarse screen 6. The coarse screen 6 intercepts larger floating and suspended solids in the wastewater, such as branches and plastic bottles, preventing these large particles from entering subsequent treatment units and causing equipment blockage and damage. Next, the wastewater enters the fine screen 7, which further removes smaller suspended solids and impurities, achieving initial purification. Starting the first pump 13 injects the wastewater from the pretreatment tank 4 into the sedimentation zone 10. The sedimentation zone 10 allows heavier particles such as silt and clay to settle to the bottom, forming sludge. After regular discharge, the second water pump 22 is started to inject the sewage in the sedimentation zone 10 into the oil removal zone 11. Oxidant is injected into the oil removal zone 11, and the motor 17 is started to drive the stirring blades 19 to stir the sewage, so that it is fully mixed and reacted, and the oil is oxidized and decomposed into harmless substances. The electric valve 20 is started to inject the oil-removed sewage into the purification zone 12. The sewage is purified through layers of ultrafiltration membranes 21 to remove dissolved organic matter, heavy metal ions and other harmful substances from the sewage, so that the treated water meets the discharge standards or reuse requirements. The third water pump 27 is started to inject the purified water into the storage tank 26 for storage.
