Description

Technical Field

[0001] This utility model relates to the field of zero-discharge engineering technology for wastewater, specifically a multi-step separation and purification zero-discharge equipment for wastewater. Background Technology

[0002] Zero wastewater discharge refers to the process where industrial water is reused, and the salt content and pollutants are highly concentrated into wastewater for complete recycling. Alternatively, water-insoluble substances can be filtered out using a filter press and then recycled, with no waste liquid discharged from the factory. In thermal power plants, however, these wastewaters are often recycled, thus requiring zero-discharge equipment to purify them.

[0003] The existing patent application, CN208414078U, includes a water collection tank, an electrocoagulation tank, a sedimentation tank, a filtration device, an ultrafiltration device, and a reverse osmosis device connected sequentially by pipes. The water collection tank is connected to an inlet pipe, and the ultrafiltration and reverse osmosis devices are each equipped with wastewater outlet pipes connected to the water collection tank. The reverse osmosis device is also equipped with an outlet pipe. This utility model provides a zero-discharge wastewater treatment device, achieving the goals of reducing wastewater treatment costs, equipment investment costs, and facilitating relocation, while simultaneously improving the quality of the effluent.

[0004] However, the purification process of this equipment is too complicated and cannot purify the wastewater more quickly, resulting in the wastewater not being put into use as soon as possible. In addition, there may be a large number of impurities in the wastewater, and these impurities are difficult to separate and treat centrally. Utility Model Content

During the rotation of the first rotating rod 16, it can drive the hinge rod 18 to move, ensuring that the subsequent wastewater and purification liquid can be fully mixed.

[0022] The top of the hinge rod 18 is provided with a movable plate 19, and the top of the movable plate 19 is provided with multiple sets of through holes 20 evenly. A water storage tank 22 is provided on one side of the treatment chamber 29, and a water pump 23 is provided on one side inside the water storage tank 22.

The bottom of the filter chamber 1 is provided with an outlet 30.

[0023] Working principle: In the wastewater treatment process, wastewater is first introduced into the wastewater inlet pipe 3, and then enters the filter chamber 1 through the injection pipe 2. The first drive motor 12 is then started, driving the rotating shaft 11 to rotate. During this rotation, the rotating shaft 11 drives the filter screen chamber 8 to rotate, and the wastewater falls to the top of the filter screen chamber 8. Fixed particulate impurities in the wastewater are blocked at the top of the filter screen chamber 8. The wastewater then enters the activated carbon 7 for filtration. Under centrifugal force, the separated solid particles are thrown into the waste collection chamber 6 for storage. The sealing plug 5 is then removed to open the waste collection chamber 6, allowing the solid particles to be removed, thus completing the cleaning process. The pre-filtered water then enters the first connecting pipe 1 through the guide plate 13. At point 4, the liquid pump 15 is started. The liquid pump 15 draws out the wastewater, which is drawn into the inlet pipe 27 and the second connecting pipe 25 and discharged from multiple spray nozzles 26. During the discharge process, the water pump 23 is started. The water pump 23 draws out the purified liquid inside the water storage tank 22 through the liquid extraction pipe 21 and sprays it out using the atomizing nozzle 24 to ensure that the purified liquid is fully mixed with the wastewater. Then, the mixture falls to the top of the moving plate 19. At this time, the second drive motor 28 is started. The second drive motor 28 drives the second rotating rod 17 and the first rotating rod 16 to rotate. Then, the first rotating rod 16 drives the hinge rod 18 and the moving plate 19 to move up and down back and forth, thereby shaking the falling liquid and further improving the mixing effect. Then, the liquid is discharged to the bottom of the treatment chamber 29 through the through hole 20 and finally discharged from the liquid outlet 30 for reuse.
