The filtration mechanism 2 includes a base 21 and multiple filter elements 22. The base 21 is installed inside the cylindrical body 1 and divides the interior of the cylindrical body 1 to form a filtration chamber 21a and an adsorption chamber 21b located below the filtration chamber 21a. The filtration chamber 21a is connected to the liquid inlet 1a and the sewage outlet 1b on the cylindrical body 1. The multiple filter elements 22 are disposed in the filtration chamber 21a and connected to the base 21. The filter elements 22 have channels 22a for connecting the filtration chamber 21a and the adsorption chamber 21b, and the filter elements 22 also have mesh areas 22b communicating with the channels 22a. The adsorption chamber 21b is provided with a resin layer 20. The backflushing mechanism 3 is installed on the cylindrical body 1 and has multiple spray elements, each of which extends into each of the channels 22a.

[0020] In actual use, aniline is delivered to the filter chamber 21a through the liquid inlet 1a. The filter element 22 filters the wastewater. The wastewater enters the adsorption chamber 21b through the mesh area 22b and the channel 22a in sequence. The filter element 22 can separate the suspended solids in the wastewater. At regular intervals, the liquid inlet 1a can be closed and the drain end 1b can be opened. Multiple spray elements spray liquid into each channel 22a to backwash the mesh area 22b. The flushing liquid and suspended solids can be output through the drain end 1b.

[0021] It should be noted that, in one embodiment, the filter element 22 is a sleeve, the sleeve has a channel 22a and is open at both ends, the lower end of the sleeve is fixedly connected to the base 21, the base 21 has a through hole corresponding to the opening, and the side wall of the sleeve has a mesh area 22b communicating with the channel 22a.

[0022] It should be noted that the distance between the mesh area and the base is 5-10cm.

[0023] Furthermore, based on the above scheme, the base 21 has a protrusion, and the protrusion and the inner wall of the cylinder 1 enclose an annular space that communicates with the filter chamber 21a, and the annular space is connected to the liquid inlet and the sewage outlet on the cylinder 1.

The infusion pipe 31 is connected to the cylinder 1, and one end of the infusion pipe 31 extends into the filter chamber 21a and is connected to the spray plate 32. Multiple spray elements 33 are connected to the spray plate 32.

[0025] Understandably, when the filter element 22 needs to be rinsed, it is connected to an external water source through the infusion pipe 31 via a booster pump, and the spray element 33 sprays liquid onto the mesh area of ​​the sleeve.

[0026] It should be noted that the spray component 33 includes a conduit 331 and a rotating nozzle 332. One end of the conduit 331 is connected to the spray disc 32, and the other end of the conduit 331 extends into the channel 22a and is connected to the rotating nozzle 332.

[0031] It should be noted that the liquid extraction mechanism 4 is a liquid extraction pump. When the valves on the inlet end 1a and the outlet end 1c are closed, the wastewater in the adsorption chamber 21b can be pumped to the inlet end 1a by the liquid extraction pump, so that the wastewater can be circulated and treated, and the aniline in the wastewater can be removed better.
