Moreover, after the sludge is broken up and filtered, a large amount of garbage impurities will still be retained on the filter screen, which is inconvenient to clean. Furthermore, after long-term use, the filtration effect will be greatly affected, reducing the applicability of the equipment.

[0007] The utility model provides the following technical solutions:

[0008] A wastewater treatment device using membrane separation technology, comprising:

[0009] A treatment box, wherein the top of the treatment box is connected to two wastewater pipes, a funnel is fixedly provided at the bottom of the treatment box, two supporting legs are fixedly provided on the bottom side of the funnel, and a support plate is fixedly provided between the two supporting legs;

[0010] The cleaning mechanism is arranged on the processing box and is used for cleaning the filtered garbage and impurities.

[0011] In a possible design, the cleaning mechanism includes a sealed door, two hooks, two hanging rods, two slide grooves, two sliders, an installation frame, two slots, a filter screen and an activated carbon filter plate. An opening is provided on one side of the treatment box, and the sealed door is rotatably connected to one side of the inner wall of the opening through a hinge. The two hooks are rotatably connected to one side of the sealed door through a damping shaft, and the two hanging rods are fixedly arranged on one side of the treatment box for the hooks to be clamped and fixed.

[0012] In a possible design, the two slide grooves are respectively opened on both sides of the inner wall of the processing box, each of the sliders is slidably connected to the inside of the slide groove, the mounting frame is fixedly set between the two sliders, and the two slots are both opened on the inner wall of the mounting frame. The filter screen and the activated carbon filter plate are respectively plugged and installed in the inside of the two slots, and the activated carbon filter plate is set at the bottom of the filter screen.

[0013] In one possible design, a card slot is opened inside the support plate, and the internal limit card of the card slot is connected to the collection box. The top of the collection box is connected to a cover plate by a hinge, and a handle is fixed on one side of the collection box.

[0014] In one possible design, a water pump is fixedly installed on the top of the support plate, and the water inlet and water outlet of the water pump are respectively connected to the water inlet pipe and the water outlet pipe. The end of the water inlet pipe away from the water pump is connected to the treatment box, and the end of the water outlet pipe away from the water pump is connected to the nanofiltration membrane cartridge. The nanofiltration membrane cartridge is fixedly installed on one side of the treatment box, and a valve is provided on the outer wall of one end of the nanofiltration membrane cartridge.

[0015] In one possible design, a motor is fixedly mounted on one side of the processing box, the output end of the motor passes through one side of the processing box and extends into the interior of the processing box, the output end of the motor is fixedly provided with a stirring shaft through a coupling, and a plurality of stirring rods are fixedly provided on the outer wall of the stirring shaft.

[0016] In this application, when in use, the wastewater first enters the treatment box simultaneously or separately through the two wastewater pipes on the top of the treatment box. The design of the two wastewater pipes allows the equipment to process wastewater from different sources or different batches. After the wastewater enters the treatment box, it is first preliminarily filtered by the filter. The filter can effectively intercept large particles of impurities, suspended matter, etc. in the wastewater to prevent these impurities from damaging subsequent treatment equipment or affecting the treatment effect. The wastewater after the preliminarily filtered by the filter continues to flow downward and contacts the activated carbon filter plate located below the filter. The activated carbon filter plate uses its porosity and adsorption properties to further remove organic matter, residual chlorine, odor and other pollutants in the wastewater. When the impurities on the filter and the activated carbon filter plate accumulate to a certain extent, they need to be cleaned. When cleaning, first open the sealed door through the hinge, pull the installation frame, and use the sliders on both sides of the installation frame to slide in the slide grooves, so that the installation frame together with the filter screen and the activated carbon filter plate can be moved out of the treatment box, and then the filter screen and the activated carbon filter plate can be easily taken out for cleaning or replacement by sliding them in the slots, which is beneficial to cleaning garbage and impurities, achieving the purpose of convenient installation and removal, ensuring the filtering effect and enhancing convenience. After cleaning, follow the reverse steps to reinstall the filter screen and the activated carbon filter plate back into the treatment box, and the sealed door is sealed and connected to the inside of the opening to enhance the sealing, and the rotating hook is hooked to the outer wall of the hanging rod, which is beneficial to fix the sealed door in a limited position to prevent it from being accidentally closed, thereby improving applicability.

[0017] When the wastewater enters the treatment tank, the motor is turned on and the motor drives the stirring shaft and the stirring rod on it to rotate, which can stir the wastewater in the treatment tank. Stirring helps to accelerate the sedimentation of suspended solids in the wastewater, promote chemical reactions or biodegradation processes, and improve the efficiency and effect of wastewater treatment. Then the water pump is started to draw the wastewater that has undergone preliminary filtration and adsorption treatment in the treatment tank through the water inlet pipe, and send it to the nanofiltration membrane cartridge through the water outlet pipe. The nanofiltration membrane in the nanofiltration membrane cartridge uses its selective permeability to further remove impurities such as dissolved solids, small molecular organic matter, bacteria, etc. in the wastewater, while allowing water molecules and some small molecular substances to pass through, thereby achieving wastewater purification. Deep purification, the treated clean water can be controlled to flow out through the valve at one end of the nanofiltration membrane tube for subsequent use or discharge. Finally, the design of the collection box can facilitate the collection and storage of garbage impurities filtered on the filter screen and activated carbon filter plate for subsequent unified treatment, which is conducive to improving treatment efficiency and avoiding a lot of time delays. When the impurities in the collection box accumulate to a certain level, the collection box can be pulled out of the card slot by the handle and the cover can be opened for cleaning. The cleaned collection box can be put back into the card slot to continue collecting impurities generated in the subsequent treatment process. The card slot can play a role in limiting the placement of it, thereby improving the convenience of use.

[0018] In the utility model, the wastewater treatment equipment using membrane separation technology can conveniently remove the filter screen and activated carbon filter plate for cleaning or replacement through the cleaning mechanism, which is conducive to cleaning garbage and impurities, achieves the purpose of convenient installation and removal, ensures the filtering effect, and enhances convenience;

[0019] In the utility model, the wastewater treatment equipment using membrane separation technology can collect and store garbage and impurities filtered by the filter screen and the activated carbon filter plate through the arrangement of the collection box, the card slot and the cover plate, so as to facilitate subsequent unified treatment, thereby improving the treatment efficiency and facilitating cleaning to continue to collect impurities generated in the subsequent treatment process;

[0020] The utility model can conveniently take out the filter screen and the activated carbon filter plate for cleaning or replacement, which is beneficial to the cleaning of garbage impurities and achieves the purpose of convenient installation and removal, preventing a large amount of garbage impurities from being retained on the filter screen and affecting the filtering effect. At the same time, it is also convenient to collect and store the garbage impurities filtered by the filter screen and the activated carbon filter plate for subsequent unified treatment.
