The thin rod 311 is fixedly connected to the output end of the motor 122, and the outer wall of the upper end of the thin rod 311 is fixedly connected to the first bevel gear 312. The gear groove on the outer wall of the first bevel gear 312 is distributed in multiple sections. One side of the first bevel gear 312 is meshed with the second bevel gear 32, and the second bevel gear 32 is rotatably connected to the inner side of the sealing plate 123. The upper end of the thick rod 33 is fixedly connected to the third bevel gear 331, which is meshed with the second bevel gear 32. The outer wall of the upper end of the thick rod 33 is fixedly connected to a plurality of cleaning rods 332. The cleaning rods 332 are non-circular and obliquely distributed. The cleaning rods 332 are attached to the outer wall of the water inlet chamber 12 at the end away from the thick rod 33. The outer wall of the thick rod 33 is provided with a plurality of oblique strip grooves 333. A blocking plate 334 is provided above the fan-shaped processing block 17. The blocking plate 334 is located near the thick rod 33. One side is fixedly connected to a roller 3341, which is movably connected to the inner side of the strip groove 333. The lower end of the thick rod 33 is fixedly connected to the electric telescopic rod 34, and the output end of the electric telescopic rod 34 is fixedly connected to a fixed ring 341. The outer wall of the fixed ring 341 is fixedly connected to multiple stirring rods 3411. The stirring rods 3411 are located in the fourth chamber 24. The bottom of the fixed ring 341 is fixedly connected to a bending rod 3412. The bending rod 3412 is fixedly connected to a scraper at the end away from the fixed ring 341. 3413, the scraper 3413 is distributed obliquely, and the scraper 3413 is parallel to the inner wall of the funnel 15, and the outer wall of the lower end of the thick rod 33 is fixedly connected to a plurality of extension rods 342, and the extension rod 342 is fixedly connected to an activated carbon plate 3421 at the end away from the thick rod 33, and the top of the activated carbon plate 3421 coincides with the position of the separation plate 141, and the separation plate 141 and the activated carbon plate 3421 are both fan-shaped rings, and the plurality of separation plates 141 and the activated carbon plates 3421 are combined to form a complete ring.

[0023] It can be seen from this that when formaldehyde wastewater needs to be treated, Figure 2-Figure 8 As shown, during the preparation stage, the staff connects the water inlet 121 to the external wastewater delivery pipe. Similarly, after connecting the medicine delivery pipe 143 to the external medicine delivery pipe, the wastewater will flow from the water inlet 121 into the No. 1 chamber 21. At this time, the wastewater will be mixed with particles, impurities or some organic matter and flow into the top position of the blocking disk 131. The wastewater will flow from the fan-shaped hole 1311 into the No. 2 chamber 22. Part of the impurities, particles and other debris in the wastewater will flow into the No. 2 chamber 22 together with the wastewater, but some may remain in the blocking disk 131. At this time, under the drive of the motor 122, the thin rod 311 drives the No. 1 bevel gear 312 to rotate, and the No. 1 bevel gear 312 will drive the No. 2 bevel gear 32 and the No. 3 bevel gear 331 to rotate. Because the bevel gear groove on the outer wall of the No. 1 bevel gear 312 is divided into multiple sections, that is, during the continuous rotation of the No. 1 bevel gear 312, the No. 3 bevel gear 331 will be driven to rotate intermittently through the No. 2 bevel gear 32, and the No. 3 bevel gear 331 is affected by the bevel gear groove angle of the No. 1 bevel gear 312. The influence is fixed at an angle. At this time, the thick rod 33 and the cleaning rod 332 are intermittently rotated by the influence of the third bevel gear 331, and the cleaning rod 332 is used to clean the debris on the top of the blocking disk 131 into the fan-shaped hole 1311 and flow into the second chamber 22 together. This makes it possible for wastewater with debris to flow from the first chamber 21 to the second chamber 22 first, and some debris enters the second chamber 22 after being cleaned, which has a certain hysteresis, which is convenient for subsequent impurity removal. At this time, in the second chamber 22, the wastewater and debris will flow together from the spiral spiral flow plate 16 to the position of the fan-shaped treatment block 17. At this time, under the obstruction of the uppermost blocking plate 334, impurities such as debris and particulate matter will be deposited in the fan-shaped treatment block 17 and eventually fall into the collection tank 171. Considering that some impurities have a hysteresis when entering the second chamber 22 under the cleaning of the cleaning rod 332, the thick rod 33 will also drive the strip groove 333 to rotate together during the intermittent subsequent rotation. At this time, the position of the strip groove 333 changes , which drives the roller 3341 and the blocking plate 334 to rotate together at a certain angle, and causes the roller 3341 and the blocking plate 334 to move up a short distance, so that an opening is formed between the blocking plate 334 and the fan-shaped processing block 17, so that the wastewater continues to flow downward from the opening. When the wastewater reaches the position of the next blocking plate 334, it is blocked again and the thick rod 33 rotates again to form an opening, and this reciprocating process is repeated, which enables multi-stage intermittent blocking treatment of impurities in the second chamber 22, and the wastewater impurity removal effect is better, and the wastewater can be effectively removed. When the wastewater reaches the flow tray 132, it flows from the flow tray 132 into the third chamber 23 and accumulates in the collection tray 142. When the water level exceeds the collection tray 142, the wastewater flows from the surrounding areas of the collection tray 142 into the fourth chamber 24. During this process, the drug is injected into the fourth chamber 24 through the drug inlet 11 and the drug inlet pipe 143, mixed with the wastewater, and stirred by the stirring rod 3411. Finally, the mixture flows out to the bottom of the funnel 15. It should be noted that during the intermittent rotation of the thick rod 33, the stirring rod 3411 and the scraper 3413 are also driven to rotate together, and the scraper 3413 is driven to fit the inner wall of the funnel 15 under the extension and contraction of the electric telescopic rod 34, so as to scrape off some of the deposited granular medicine and mix it with the wastewater to ensure the mixing effect; In addition, when dealing with formaldehyde wastewater of different concentrations, an activated carbon plate 3421 can also be installed in the fan-shaped treatment block 17 to initially reduce the concentration of the formaldehyde wastewater in the No. 2 chamber 22, and the wastewater flowing out into the collection tray 142 will utilize the rotation of the thick rod 33 and the fixed extension rod 342 to drive the activated carbon plate 3421 for a second reduction in concentration. Finally, the drugs are mixed in the No. 4 chamber 24 to complete the final treatment. In this way, progressive treatment can effectively treat formaldehyde wastewater of different concentrations.
