[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when the device is used to treat sewage, the water inlet pipe 2 is connected to the sewage pipe, the water outlet pipe 3 is connected to the collecting device, and the sewage is injected into the outer shell 1 from bottom to top through the water inlet pipe 2, and the sewage contacts the filter cartridge 6 from the bottom of the filter cartridge 6. Since the surface of the filter cartridge 6 is provided with an annular groove, the contact area between the sewage and the activated carbon in the filter cartridge 6 increases during the contact between the sewage and the filter cartridge 6, and the sewage enters from the bottom to avoid excessive sewage flow rate due to the gravity of the sewage, thereby increasing the contact area and time between the sewage and the activated carbon, thereby increasing the adsorption efficiency of the activated carbon on the sewage.

[0033] The device has the effect of detachable filter cartridge, specifically:

[0034] A connection structure is provided on the surface of the filter cartridge 6, and a connection block 7 and a clamping block 9 are provided on the connection structure so that the filter cartridge 6 can be quickly connected and disassembled with the inner wall of the housing 1. The connection structure includes a connection block 7, which is distributed in an annular manner on the upper surface of the filter cartridge 6, and a circular threaded hole is provided on the surface of the connection block 7. A connection bolt 8 is provided at a corresponding position on the surface of the housing 1, and the connection bolt 8 is threadedly connected to the surface of the housing 1.

A clamping groove 10 is provided on the inner wall of the housing 1, and the cross section of the clamping groove 10 is L-shaped.

[0035] like Figure 2 and Figure 3 As shown, when the filter cartridge 6 needs to be cleaned and replaced, the upper part of the housing 1 is opened using the connecting flange 5, and the connecting bolts 8 are rotated to separate the connecting bolts 8 from the connecting block 7. At this time, the filter cartridge 6 can be held and pulled out of the housing 1 to clean or replace the filter cartridge 6.

After the device completes the sewage treatment, the suspended matter can be discharged from the outer shell 1 through the slag discharge pipe 4.

[0039] Working principle: When using the improved activated carbon filter, a circular groove is set on the lower surface of the filter cartridge 6, so that the contact area between the sewage and the filter cartridge 6 is increased, the contact area between the sewage and the activated carbon is increased, and the adsorption efficiency of the activated carbon is improved. The filter cartridge 6 can be connected and disassembled by using the connecting block 7 set on the upper surface of the filter cartridge 6 and the connecting bolts 8 on the surface of the outer shell 1, which is convenient for replacing and cleaning the filter cartridge 6. A filter plate 11 is set below the filter cartridge 6 to intercept suspended matter in the sewage. An impeller 12 is set in the water inlet pipe 2.
