It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] like Figure 1 and 2 As shown, a bio-based composite adsorption wastewater filtration system includes an outer shell 1 and a separation cylinder 2. There are several separation cylinders 2, and the several separation cylinders 2 are concentrically arranged. The bottom ends of the several separation cylinders 2 are fixedly connected to the bottom end of the inner wall of the outer shell 1. The surface of the separation cylinder 2 is provided with evenly distributed water holes 21. A filter layer mounting part 3 is provided between two adjacent separation cylinders 2. The several filter layer mounting parts 3 are sequentially provided with a pebble layer 31, a gravel layer 32, an activated carbon layer 33 and a biofilm layer 34 from the inside to the outside. The water outlet 4 is between the outermost separation cylinder 2 and the inner wall of the outer shell 1. The bottom of the outer shell 1 is fixedly connected with a plugging component 5 by screws, and one end of the plugging component 5 passes through the several separation cylinders 2 in sequence. The top end of the outer shell 1 is threadedly connected with a top cover 6, and the middle part of the top end of the top cover 6 is fixedly connected with a water inlet pipe 61.

[0021] According to the above structure, when in use, the wastewater to be filtered is passed into the innermost partition cylinder 2 through the water inlet pipe 61, and the wastewater is filtered through the pebble layer 31, the gravel layer 32, the activated carbon layer 33 and the biofilm layer 34 in turn, and finally enters the interior of the water outlet 4. Since the pebble layer 31, the gravel layer 32, the activated carbon layer 33 and the biofilm layer 34 are all arranged in a cylindrical shape, the filtration area is the side area of ​​the cylinder. Compared with the traditional upright filter whose filtration area is the cross-section of the cylinder, the filtration area is larger, thereby improving the filtration efficiency.

[0022] like Figure 1 and 2 As shown, the bottom end of the shell 1 is a sloped structure, the bottom of the side wall of the shell 1 is provided with a through hole matching the blocking component 5, the outer wall of the shell 1 is fixedly connected with a T-shaped plate 11, the T-shaped plate 11 is arranged corresponding to the through hole, and the bottom end of the shell 1 is provided with a water outlet pipe 12, which is connected to the water outlet part 4.

[0023] According to the above structure, the filtered water entering the water outlet portion 4 flows along the inclined surface of the bottom end of the housing 1 into the water outlet pipe 12 , and finally the filtered water is discharged through the water outlet pipe 12 .

[0024] like Figure 4 As shown, the biofilm layer 34 includes a plurality of layers of cellulose films 341 wound in sequence, and a polydopamine layer 342 is disposed on one side of the cellulose film 341 .

[0025] According to the above structure, the cellulose membrane 341 has the excellent properties of wide source, renewable, degradable, low cost and zero carbon emission. The biofilm layer 34 produced using the cellulose membrane 341 is not only low cost, but also easy to degrade after use, thereby reducing pollution. The polydopamine layer 342 is degradable and has excellent adsorption performance, which improves the filtration effect of the biofilm layer 34 and is degradable after disposal without producing pollutants.

[0026] like Figure 2 and 3 As shown, the sealing component 5 includes a sealing plate 51, one end of which is fixedly connected to an arched column 52, which passes through the T-shaped plate 11 and is inserted into the interior of the outer shell 1, and a groove 53 is provided at the bottom of the arched column 52, which is arranged inside the water outlet part 4, and the sealing plate 51 is fixedly connected to the T-shaped plate 11 by bolts, and a groove matching the arched column 52 is provided at the bottom of the side wall of the partition tube 2.

[0027] According to the above structure, the groove at the bottom of the side wall of the separation cylinder 2 is convenient for cleaning the filter material between the water holes 21. After using for a period of time, the filter material between the separation cylinders 2 needs to be replaced. When replacing, remove the bolts used to connect the sealing plate 51 and the T-shaped plate 11, and then pull out the arched plug 52. The filter material between the separation cylinders 2 is discharged through the groove on the side wall of the separation cylinder 2, which is convenient for removing the filter material. After the filter material is taken out, unscrew the top cover 6, and then install the sealing component 5, and then add the filter material from the top of the outer shell 1, which is convenient for replacing the filter material.

[0028] The working principle of the utility model is as follows: when in use, the wastewater to be filtered is passed through the water inlet pipe 61 into the innermost separation cylinder 2, and the wastewater is filtered through the pebble layer 31, the gravel layer 32, the activated carbon layer 33 and the biofilm layer 34 in turn, and finally enters the interior of the water outlet 4. Since the pebble layer 31, the gravel layer 32, the activated carbon layer 33 and the biofilm layer 34 are all arranged in a cylindrical shape, the filtration area thereof is the side area of ​​the cylinder, and compared with the filtration area of ​​the traditional upright filter which is the cross-section of the cylinder, the filtration area is larger, and the filtration efficiency is improved. The filtered water entering the water outlet 4 flows along the inclined surface at the bottom end of the outer shell 1 to the water outlet pipe 12, and finally the filtered water is discharged through the water outlet pipe 12, and the cellulose The membrane 341 has the excellent properties of wide source, renewable, degradable, low cost and zero carbon emission. The biofilm layer 34 produced by using the cellulose membrane 341 is not only low in cost, but also easy to degrade after use, thereby reducing pollution. The polydopamine layer 342 is degradable and has excellent adsorption performance, which improves the filtration effect of the biofilm layer 34, and is degradable after disposal without producing pollutants. After using it for a period of time, remove the bolts used to connect the sealing plate 51 and the T-shaped plate 11, and then pull out the arched plug 52. The filter material between the dividing tubes 2 is discharged through the groove on the side wall of the dividing tube 2, which is convenient for removing the filter material. After the filter material is taken out, unscrew the top cover 6, and then install the sealing component 5, and then add the filter material again from the top of the outer shell 1.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
