[0027] The installation assembly 5 comprises a pull frame 501, a multi-hole plate 502, an installation plate 503, a handle 504 and a connecting screw 505, the pull frame 501 is movably connected in the interior of the installation groove 4, the multi-hole plate 502 is fixedly connected to the bottom of the inner wall of the pull frame 501, the installation plate 503 is fixedly connected to the outer side of the pull frame 501, the handle 504 is fixedly connected to the side of the installation plate 503 away from the bed body 2, the connecting screw 505 is threadedly connected to the interior of the installation plate 503, and the right side of the bed body 2 is provided with a threaded groove matched with the connecting screw 505.

[0028] In the embodiment, when the adsorbent needs to be filled, the pull frame 501 is pushed into the installation groove 4, so that the pull frame 501 can accurately enter the predetermined position, and when the pull frame 501 reaches the appropriate position, the connecting screw 505 on the installation plate 503 is threadedly connected with the threaded groove on the right side of the bed body 2, so that the pull frame 501 can be fixed in the interior of the bed body 2, and when the adsorbent needs to be replaced or the interior of the pull frame 501 needs to be inspected and maintained, the connecting screw 505 is unscrewed, and the pull frame 501 is pulled out of the installation groove 4 by holding the handle 504, so that the pull frame 501 is pulled out of the installation groove 4, which is convenient and fast, and facilitates subsequent rapid replacement of the adsorbent, thereby improving the use convenience.

[0029] Specifically, as shown in Figure 1 , Figure 5 , the outer frame 601 is fixedly connected to the top of the bed body 2, the interior of the outer frame 601 is provided with an inner frame 602, and the interior of the inner frame 602 is fixedly connected with a filter screen 603.

[0030] Specifically, as shown in Figure 5 , the two sides of the outer frame 601 are provided with through holes 604, the inner walls of the through holes 604 are made of flexible material, the interiors of the through holes 604 are movably connected with movable blocks 605, and the movable blocks 605 are fixedly connected to the two sides of the inner frame 602.

[0031] Specifically, as shown in Figure 5 , the interiors of the through holes 604 are fixedly connected with sliding rods 606, and the movable blocks 605 are slidingly connected to the surfaces of the sliding rods 606.

[0032] Specifically, as shown in Figure 2 , Figure 5 , the two sides of the outer frame 601 are fixedly connected with control motors 7, and the output ends of the control motors 7 are fixedly connected with discs 8.

[0033] Specifically, as shown in Figure 2 , Figure 5 , the surfaces of the discs 8 are rotatably connected with adjusting rods 9, and the sides of the adjusting rods 9 close to the movable blocks 605 are rotatably connected with the movable blocks 605.

[0034] In the embodiment, when the sewage enters the interior, the filter screen 603 can intercept the solid impurities with large particles in the sewage, and the filter screen 603 can effectively block the impurities, so that only the sewage with less impurities enters the subsequent link. Meanwhile, the control motor 7 drives the disc 8 to rotate. With the rotation of the disc 8, the adjusting rod 9 connected to the surface of the disc 8 drives the movable block 605 to slide up and down along the slide rod 606, so that the inner frame 602 also moves up and down along the slide rod 606 together with the movable block 605. Then the filter screen 603 vibrates correspondingly, so that the solid impurities attached to the surface of the filter screen 603 gradually separate from the filter screen 603, preventing the filter screen 603 from being blocked, and thus improving the phosphorus removal efficiency of the adsorbent.

[0035] Specifically, as shown in Figure 3 The front side and the rear side of the pull-out frame 501 are fixedly connected with the limiting blocks 11, and the limiting blocks 11 are used in cooperation with the limiting grooves 10.
