Embodiment 1
[0045] Such as Figure 5 As shown, the membrane filter for water treatment includes the membrane module mentioned in the above specific embodiment and the aeration device 300 that can act on the membrane module, wherein the collector support seat 213 is disc-shaped, and the The film strips 111 are distributed on the upper surface of the current collecting support seat 213 in the form of an array; The strips 111 are arranged in parallel, so as to form parallel sewage discharge channels in the filter unit 100, which facilitates the discharge of sewage.
[0046] In the membrane filter of embodiment 1, the membrane strip 111 length L that adopts is 1000 millimeters, and width W is 16 millimeters, and thickness H is 2 millimeters, and then the membrane area of each membrane strip 111 is 2 (W+H) ×L=0.036m 2 . The diameter of the collecting support seat 213 is 1000 mm, and there are altogether 15,000 membrane strips 111 distributed on the upper surface of the collecting support ...
Embodiment 2
[0048] Such as Figure 6 As shown, the membrane filter for water treatment includes the membrane module mentioned in the above specific embodiment and the aeration device 300 that can act on the membrane module, wherein the collector support seat 213 is disc-shaped, and the The film strips 111 are distributed on the upper surface of the current collecting support seat 213 in an array; the film strips 111 are specifically distributed on the upper surface of the current collecting support seat 213 in an annular array, and each film in the film strips 111 of the annular array The sides of the strip 111 are all aligned with the same circle centered on the center of the annular array of the film strip 111 (such as Figure 6 The circle 120) in the filter unit 100 is tangent, thereby forming an annular sewage discharge channel in the filter unit 100, which is beneficial to the discharge of sewage.
Embodiment 3
[0050] Such as Figure 6 As shown, the membrane filter for water treatment includes the membrane module mentioned in the above specific embodiment and the aeration device 300 that can act on the membrane module, wherein the collecting support seat 213 is tubular, and the collecting support seat A plurality of film strips 111 arranged at intervals along the length direction of the collector support base 213 are vertically installed on the 213 . In addition, the membrane filter of Example 3 also includes a limiting structure disposed outside the filter unit 100 to limit the movable range of the free end 111b of the membrane strip 111 . The limiting structure specifically adopts a surrounding frame arranged outside the filter unit 100 .
[0051] Different from the membrane modules in the above specific embodiments and examples, Figure 8 The shown membrane module includes: a filter unit 100, the filter unit 100 includes a membrane element 110, the membrane element 110 includes ...
