[0028] like Figures 1 to 6 As shown, the device includes a main body 3, which has an inlet chamber 9, a separation chamber 11 and an oxidation chamber 12. The inlet chamber 9 is equipped with a pre-separation component 2 for filtering suspended particulate matter in wastewater, and the separation chamber 11 is equipped with a membrane separation component 1 for secondary filtration of wastewater. An ozone generator 5 is provided on the side of the main body 3.

[0029] Specifically, the pre-separation component 2 can rotate rapidly in the inlet chamber 9 to filter out larger suspended particles in the wastewater, while the membrane separation component 1 can seal the separation chamber 11. Then, the membrane separation component 1 moves in the separation chamber 11. Under the action of air pressure, the filtration speed of wastewater on the membrane surface is greatly increased, thereby improving the wastewater treatment efficiency of the device.

[0030] The membrane separation assembly 1 includes a sealing frame 102, which is movably connected to the main body 3. A moving groove 101 is provided in the sealing frame 102, and a moving screw 103 is provided in the moving groove 101. The moving screw 103 is rotatably connected to the moving groove 101. A moving motor 104 is fixed to one end of the moving screw 103. An installation plate 105 is provided in the sealing frame 102, and the installation plate 105 is movably connected to the sealing frame 102. The installation plate 105 is threadedly connected to the moving screw 103. A guide groove 106 is provided on the bottom surface of the installation plate 105. An installation frame 109 is provided at the bottom of the installation plate 105. A guide strip 107 is provided on the top surface of the installation frame 109, and the guide strip 107 is movably connected to the guide groove 106. A separation membrane 108 is provided in the installation frame 109.

[0031] Specifically, in the membrane separation assembly 1, under the action of the electric telescopic rod 13, the sealing frame 102 can be raised and lowered on the top surface of the main body 3. When the sealing frame 102 is in contact with the main body 3, the separation chamber 11 becomes a sealed space. At this time, driven by the moving motor 104, the mounting frame 109 moves in the separation chamber 11 with the separation membrane 108 to quickly separate the sewage. The guide groove 106 on the bottom surface of the mounting plate 105 and the guide strip 107 on the mounting frame 109 make it easy to disassemble and replace the mounting frame 109 and the separation membrane 108.

[0032] The pre-separation assembly 2 includes a partition 203. A filter cylinder 201 is provided on the top surface of the partition 203 and is rotatably connected to the partition 203. A gear ring 202 is provided on the surface of the filter cylinder 201. A rotary motor 204 is provided on the bottom surface of the partition 203 and its output end passes through the partition 203. A transmission gear 206 is provided at the output end of the rotary motor 204 and meshes with the gear ring 202. A lifting motor 208 is provided at the bottom of the partition 203 and its output end is provided with a lifting screw 207. A lifting seat 205 is provided on the surface of the partition 203 and passes through the partition 203. The lifting seat 205 is movably connected to the partition 203 and the lifting screw 207 is threadedly connected to the lifting seat 205.

[0033] Specifically, in the pre-separation component 2, when the sewage enters the filter cylinder 201 from the bottom, the transmission gear 206 drives the gear ring 202 on the surface of the filter cylinder 201 to rotate under the drive of the rotary motor 204. Then, under the action of centrifugal force, the particulate suspended matter in the sewage is quickly separated, while the pre-treated sewage remains in the inlet chamber 9. Then, under the drive of the lifting motor 208, the lifting screw 207 moves the lifting seat 205 upward, and discharges the sewage at the top of the partition 203 into the separation chamber 11 from the overflow pipe 10.

[0034] The ozone generator 5 has a gas distribution pipe 8 on its surface, and nozzles 14 are arrayed on the surface of the gas distribution pipe 8. The main body 3 has a liquid outlet pipe 6 on its side, and the liquid outlet pipe 6 passes through the side of the oxidation chamber 12. The main body 3 has an overflow pipe 10 on its surface, and the two ends of the overflow pipe 10 pass through the side of the liquid inlet chamber 9 and the separation chamber 11, respectively. A through groove 7 is opened between the separation chamber 11 and the oxidation chamber 12. The main body 3 has an electric telescopic rod 13, and the output end of the electric telescopic rod 13 is fixedly connected to the sealing frame 102. The main body 3 has a controller 4 on its surface, and the controller 4 is electrically connected to the moving motor 104, the rotating motor 204, the lifting motor 208, the ozone generator 5, and the electric telescopic rod 13, respectively.

[0035] Specifically, after the filtered water enters the oxidation chamber 12, the ozone generated by the ozone generator 5 enters the oxidation chamber 12 through the gas distribution pipe 8 and then through the nozzle 14. Utilizing the strong oxidizing properties of ozone, the organic matter, color, odor and some heavy metals in the sewage are oxidized and decomposed, thereby improving the water quality of the sewage.

[0036] In summary: In membrane separation assembly 1, under the action of electric telescopic rod 13, sealing frame 102 can be raised and lowered on the top surface of main body 3. When sealing frame 102 is in contact with main body 3, separation chamber 11 becomes a sealed space. At this time, driven by moving motor 104, mounting frame 109 moves with separation membrane 108 in separation chamber 11 to quickly separate sewage. The guide groove 106 on the bottom surface of mounting plate 105 and guide strip 107 on mounting frame 109 make it easy to disassemble and replace mounting frame 109 and separation membrane 108. In pre-separation assembly 2, when sewage enters filter cylinder 201 from the bottom, driven by rotary motor 204, transmission gear 206 rotates gear ring 202 on surface of filter cylinder 201. Then, under the action of centrifugal force, particulate suspended solids in sewage are quickly separated. The pretreated wastewater remains in the inlet chamber 9. Then, driven by the lifting motor 208, the lifting screw 207 moves the lifting seat 205 upward, discharging the wastewater at the top of the partition 203 into the separation chamber 11 through the overflow pipe 10. After the filtered water enters the oxidation chamber 12, the ozone generated by the ozone generator 5 enters the oxidation chamber 12 through the gas distribution pipe 8 and then through the nozzle 14. Utilizing the strong oxidizing properties of ozone, the organic matter, color, odor, and some heavy metals in the wastewater are oxidized and decomposed, improving the water quality of the wastewater. The pre-separation component 2 can rotate rapidly in the inlet chamber 9 to filter out larger suspended particles in the wastewater. The membrane separation component 1 can seal the separation chamber 11. Then, the membrane separation component 1 moves within the separation chamber 11. Under the action of air pressure, the filtration speed of the wastewater on the membrane surface is greatly increased, improving the wastewater treatment efficiency of the device.
