[0056] It should be noted that the raw liquid can enter the first upper cover 101 through the first liquid inlet 109 of the primary filter module 1, and the liquid returns to the raw liquid container from the first liquid outlet 110 through the first channel area formed by the first filter membrane and the first groove 108. During this process, part of the filtrate will pass through the first filter membrane and enter the first filtrate area to form a primary filtrate.

[0057] Furthermore, a second filter membrane is sandwiched between the second support member 202 and the second upper cover 201, and the second filter membrane is supported by the second solid portion 207 of the second support member 202.

During this process, part of the liquid in the primary filtrate passes through the second filter membrane and enters the second filtrate area to form a secondary filtrate.

[0059] Further, the pore size of the first filter membrane is larger than the pore size of the second filter membrane;

[0060] It should be noted that, under the premise that the pore size of the first filter membrane is larger than the pore size of the second filter membrane, the pore size range of the first filter membrane can be 5-100um, preferably 5-50um, more preferably 10um, 20um, 25um or 30um; the pore size range of the second filter membrane can be 0.01-25um, preferably 0.01-10um, more preferably 0.2um, 0.5um, 1um, 2um or 5um;

[0061] Among them, the first filter membrane is mainly used for filtering and collecting filtrate; the second filter membrane is mainly used for concentrating the filtrate and removing waste liquid.

[0062] Furthermore, a first retaining groove 112 is provided at the first inlet 104 of the first lower cover 103 .

[0063] Furthermore, a second retaining groove 214 is provided at the second inlet 204 of the second lower cover 203 .

[0066] Furthermore, the second hollow portion 206 of the second support member 202 is a spiral structure or a circular structure, and the second groove 208 of the second upper cover 201 is a spiral structure or a circular structure correspondingly.

[0067] It should be noted that the spiral structure or the spiral structure can fully filter the raw liquid or the primary filtrate, and increase the distance that the raw liquid or the primary filtrate passes through the filtration channel within a limited space.

[0068] Furthermore, the first lower cover 103 and the second lower cover 203 are box-shaped structures.

[0069] Furthermore, the second outlet 205 of the second lower cover 203 is a closable structure.

[0070] It should be noted that the second outlet 205 is a closable structure, so that more levels of filter modules can be expanded. When the second outlet 205 is closed, the two-stage filter structure provided in the embodiment of the present application is realized; when the second outlet 205 is not closed, the number of filter modules can be expanded through the second outlet 205, or the second filtrate area of ​​the second filter module 2 can be expanded.

During this process, part of the filtrate will pass through the first filter membrane and enter the first filtrate area to form a primary filtrate.

[0075] The primary filtrate passes through a power pump and enters the second filter membrane of the secondary filter module 2 from the first outlet 105 of the primary filter module 1 and the second channel area formed between the second filter membrane and the second groove 208 of the second upper cover 201, and returns to the first filtrate area from the second liquid outlet 210 of the secondary filter module 2. During this process, part of the liquid in the primary filtrate passes through the second filter membrane and enters the second filtrate area to form a secondary filtrate.
