By setting the filter device 3, some floating objects, solid impurities, stones and other garbage in the sewage flowing in the water inlet 2 are intercepted, preventing them from entering the water inlet 2 and causing accumulation and clumping at the water inlet 2, which would block the water inlet 2, affect the working efficiency of the water inlet 2, and improve the practicality of the device. The surface of the sewage treatment device body 1 is provided with a volume control device 4. By setting the volume control device 4, the staff can accurately add chemicals for treating sewage, avoiding the inaccurate sewage treatment caused by adding too much or too little chemicals, and improving the accuracy of chemical dosing.

[0032] The specific setup and function of its filter device 3 and flow control device 4 will be explained below.

[0033] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in this embodiment: the filter device 3 includes a filter screen 301, which is slidably connected to the inner surface of the water inlet 2. A limiting ring 302 is fixedly connected to the inner surface of the water inlet 2, and the surface of the limiting ring 302 is slidably connected to the filter screen 301. A drain outlet 304 is provided on the arc surface of the water inlet 2. A sliding frame 305 is fixedly connected to the surface of the sewage treatment device body 1.

A pull rod 308 is slidably inserted, with a pull plate 309 fixedly connected to one end of the pull rod 308. A first spring 310 is fitted onto the arc surface of the pull rod 308, with both ends of the first spring 310 fixedly connected to the first extension plate 307 and the pull plate 309, respectively. One end of the pull rod 308 is slidably connected to the arc plate 306. Two first threaded rods 303 are threadedly inserted into the arc surface of the water inlet 2, and the first threaded rods 303 are slidably connected to the surface of the filter screen 301, achieving the effect of limiting and fixing the filter screen 301, preventing the filter screen 301 from sliding out of the water inlet 2, and improving the stability of the device. The surface of the filter screen 301 is fixed. A long rod 311 is connected, with a handle 312 fixedly connected to one end of the long rod 311. This facilitates the removal of the filter screen 301 from the water inlet 2 by staff for regular maintenance and replacement, improving the convenience of the device. A U-shaped frame 313 is fixedly connected to the surface of the wastewater treatment device body 1. Two sliding grooves are formed on the inner surface of the U-shaped frame 313. Sliding blocks 315 are slidably connected to the inner surface of the sliding grooves of the U-shaped frame 313. A collection box 314 is fixedly connected to the side of the two sliding blocks 315 that are close to each other. Slots are formed on the surface of the sliding blocks 315. Two L-shaped plates 316 are rotatably connected to the surface of the U-shaped frame 313. A rod 317 is slidably inserted into the inner surface of the slider 315 slot. One end of the rod 317 is fixedly connected to a circular plate 318. The rod 317 is slidably connected to the inner surface of the slot of the slider 315, which achieves the effect of collecting some floating objects, solid impurities, stones and other garbage that fall from the drain outlet 304, making it convenient for staff to remove and clean them at once. A second spring 319 is fitted on the arc surface of the rod 317. The two ends of the second spring 319 are fixedly connected to the L-shaped plate 316 and the circular plate 318 respectively. Under the force of the second spring 319, the rod 317 is automatically springed back into the hole of the slider 315 and will not fall out.

[0034] Reference Figure 7 and Figure 8As shown, specifically, the measuring device 4 includes a hollow tube 41, which is connected to the surface of the sewage treatment device body 1. A graduated cup 42 is fixedly connected to the surface of the hollow tube 41. A round hole is opened on the bottom surface of the graduated cup 42, which is connected to the hollow tube 41.

A second threaded rod 47 is threaded into the second extension plate 43. One end of the second threaded rod 47 is threadedly connected to the rotating rod 44. A sealing gasket 46 is fixedly connected to the surface of the baffle 45. The sealing gasket 46 is made of rubber. The surface of the sealing gasket 46 is slidably connected to the round hole of the graduated cup 42. The rubber material has good sealing and elasticity, which can fill the gap between the round hole on the graduated cup 42 and the baffle 45.

[0035] Working principle: When sewage is transported into the sewage treatment device body through water inlet 2, the filter screen 301 intercepts floating objects, solid impurities, stones, and other debris in the sewage flowing through water inlet 2, preventing them from entering the sewage treatment device body 1. After the sewage is pumped out, the intercepted debris remains in water inlet 2. Pulling down the pull plate 309 causes the pull rod 308 to slide down within the first extension plate 307, releasing the pull rod 308 from the arc-shaped... When plate 306 is in its limiting position, the first spring 310 is in a stretched state. Moving the arc-shaped plate 306 causes it to slide backward on the arc surface of the sliding frame 305, releasing the limiting position on the drain outlet 304. Releasing the pull plate 309 releases the tension of the first spring 310, causing the pull rod 308 to automatically rebound, thus limiting the arc-shaped plate 306 again to prevent it from sliding on the sliding frame 305. Debris remaining in the water inlet 2 will then fall downward through the drain outlet 304. Inside the collection box 314, pulling the circular plate 318 causes the insert rod 317 to slide out of the slot in the slider 315. At this time, the second spring 319 is in a stretched state. Rotating the L-shaped plate 316 downwards releases the limit on the collection box 314, releasing the circular plate 318. The second spring 319 releases its stretching force, pressing one end of the insert rod 317 against the surface of the U-shaped frame 313 to prevent the insert rod 317 from falling. Pulling the collection box 314 causes it to slide out of the U-shaped frame 313. The filter screen 301 slides outward, allowing staff to easily remove and clean the waste in one go. When the filter screen 301 needs to be inspected or replaced, the first threaded rod 303 is rotated outward to release the first threaded rod 303 from the filter screen 301. The handle 312 is then pulled outward, causing the long rod 311 and the filter screen 301 to slide out from the water inlet 2. This achieves the effect of regular inspection and replacement of the filter screen 301, which helps to extend the service life of the filter device 3 and improves the stability of the device.

[0036] Working principle: When the operator needs to use the volume control device 4, they pour the wastewater treatment chemicals into the graduated cup 42. Then, they observe the measurement in the graduated cup 42 to prevent the chemical from being poured in too much or too little. After the accurately measured amount of chemical has been poured in, the operator rotates the second threaded rod 47, allowing it to rotate out of the rotating rod 44, thus releasing the restriction on the rotating rod 44. Rotating the rotating rod 44 causes the baffle 45 and the sealing gasket 46 to rotate together, releasing the restriction on the circular hole on the bottom surface of the graduated cup 42, allowing the chemical to enter the hollow tube 41, and finally enter the wastewater treatment device body 1 through the hollow tube 41. By setting up the volume control device 4, the operator can accurately add the wastewater treatment chemicals, avoiding inaccurate wastewater treatment due to adding too much or too little chemicals, and improving the accuracy of chemical dosing.
