Water in the water injection chamber 103 will enter the activated carbon filter chamber 3 through the upper sealing ring 10 and the top opening of the activated carbon filter chamber 3. Two filter plates 12 are fixedly connected to the inner wall of the activated carbon filter chamber 3. Activated carbon is filled between the two filter plates 12. Water entering the activated carbon filter chamber 3 will pass through the two filter plates 12 and the activated carbon, and then be discharged from the inner ring cavity of the lower sealing ring 11, thus achieving activated carbon filtration.

[0046] Specifically, the top of the treatment tank 1 has a lap joint 13 and a threaded butt joint ring 47, a first threaded surface 14 is formed on the outer ring surface of the threaded butt joint ring 47, a pressing cover 15 is fixedly connected to the inner top surface of the cover body 101 and presses against the top of the upper sealing ring 10, a second threaded surface 16 is formed on the inner edge of the cover body 101, after the second threaded surface 16 is threadedly connected with the first threaded surface 14, a drainage cavity 102 is formed between the threaded butt joint ring 47, the cover body 101 and the pressing cover 15, a water passage 104 is formed on the top of the treatment tank 1 and communicates with the drainage cavity 102, a water injection cavity 103 is formed on the inner side of the pressing cover 15, the water inlet pipe 8 penetrates through the cover body 101 and enters the water injection cavity 103, the water outlet pipe 9 penetrates through the cover body 101, the water injection cavity 103 and the pressing cover 15 in sequence and then enters the drainage cavity 102 and is pressed against by the pressing cover 15, the filter body enters the inside of the treatment tank 1 through the water passage 104, and the upper sealing ring 10 is lapped in the lap joint 13. It should be understood that the filter body is installed in the treatment tank 1 by clamping of the pressing cover 15 and the base 2, and when maintenance is needed, the filter body can be directly taken out by unscrewing the cover body 101, which is convenient to operate.

[0047] The specific byproduct treatment method is as follows:

[0048] Step one, drink water is injected through the water injection cavity 103, and the drink water enters the drainage cavity 102 through the activated carbon filter chamber 3, the drainage assembly, the intermediate filter cavity 5, the annular semi-permeable membrane 4, the liquid storage cavity 6 and the water passage 7 in sequence, the activated carbon in the activated carbon filter chamber 3 performs primary filtration on the byproducts in the drink water, and the annular semi-permeable membrane 4 performs secondary filtration on the byproducts in the drink water;

[0049] Step two, after a period of filtration, the water injection of the water injection cavity 103 is stopped, the intermediate filter cavity 5 is communicated with the outside of the base 2 through the drainage assembly, the water in the intermediate filter cavity 5 flows out, the drink water stored in the liquid storage cavity 6 enters the intermediate filter cavity 5 after being filtered by the annular semi-permeable membrane 4, the flow of water performs reverse flow cleaning on the annular semi-permeable membrane 4, and the filtered material cleaned is discharged through the drainage assembly, so that the cleaning of the filtered material in the intermediate filter cavity 5 is realized;

[0050] Step three, after cleaning, the communication with the outside of the base 2 is cancelled through the drainage assembly, and the working state of filtration is restored, so that the filter body is not removed and cleaned.

[0051] As can be seen from the above processing method, when the impurities filtered in the intermediate filtering cavity 5 need to be cleaned, the intermediate filtering cavity 5 is communicated with the outside of the base 2 through the drainage assembly, the drinking water in the intermediate filtering cavity 5 flows out, the drinking water stored in the storage cavity 6 flows into the intermediate filtering cavity 5 after being filtered by the annular semi-permeable membrane 4, the water flow can clean the annular semi-permeable membrane 4 in the reverse direction, and the filtered impurities are discharged through the drainage assembly, so that the impurities in the intermediate filtering cavity 5 are cleaned. During the whole cleaning process, the filter body does not need to be taken out, and the reverse flow of the filtered water can clean the annular semi-permeable membrane 4, which provides convenience for the staff to clean the filter body. In addition, the water flowing out of the drainage assembly flows downward from the top end of the intermediate filtering cavity 5, and the downward flow of the water can drive the filtered impurities in the annular surface of the annular semi-permeable membrane 4, which is beneficial to completely clean the filtered impurities.

The water filtered by the activated carbon enters the drainage assembly through the one-way valve 19, enters the intermediate filtering cavity 5 under the drainage effect of the drainage assembly, is subjected to secondary filtering by the annular semi-permeable membrane 4 in the intermediate filtering cavity 5, and is subjected to two-stage filtering. The water subjected to two-stage filtering enters the drainage cavity 102 through the water inlet hole 7, is discharged after being filtered, realizes filtering, and is discharged. When the sewage needs to be discharged, the plugging plug 20 is removed from the bottom end of the drainage pipe 17, the water in the intermediate filtering cavity 5 flows into the drainage pipe 17 from the drainage port 21, and then is discharged from the bottom end of the drainage pipe 17, so that the filtered impurities in the intermediate filtering cavity 5 are discharged.
