Embodiment 1

[0025] Filter the water in lakes and rivers to prepare domestic water, and set the parameters of the water purification treatment components as follows: Add polymers to dimethyl sulfoxide to form a 20% polymer solution to form a casting solution. Inject the casting solution into the groove mold, and place the bottom of the mold in liquid nitrogen to solidify the casting solution. After it is completely solidified, take it out of the mold and place it in a freeze-drying environment to obtain a pore diameter range of 1-5 μm and a pore wall thickness. Through-hole membranes in the range of 4 to 5 μm. Control the height of the casting solution to set the thickness of the perforated membrane to 20 mm, the filter layer is cationic resin with a thickness of 5 mm, and the mesh number of the metal screen is 100 mesh to obtain a water treatment membrane module. After testing, the filtration efficiency of the water treatment membrane module of the present invention for particles with a p...

Embodiment 2

[0027] To filter the sewage discharged by chemical enterprises, the parameters of the water purification treatment components are set as follows: add the high polymer to 1,4-dioxane to form a high polymer solution with a concentration of 10% to form a casting solution. Inject the casting solution into the groove mold, and place the bottom of the mold in liquid nitrogen to solidify the casting solution. After it is completely solidified, take it out of the mold and place it in a freeze-drying environment to obtain a pore diameter range of 20-30 μm and a hole wall thickness. Through-hole membranes in the range of 2 to 3 μm. Control the height of the casting solution to set the thickness of the perforated membrane to be 1 mm, the filter layer is activated carbon particles, and its thickness is 25 mm, and the mesh number of the metal screen is 50 mesh to obtain a water treatment membrane module. After testing, the filtration efficiency of the water treatment membrane module of the...

Embodiment 3

[0029] For wastewater treatment with high viscosity in printing and dyeing plants, the parameters of the water purification treatment components are set as follows: add the high polymer to 1,4-dioxane to form a high polymer solution with a concentration of 2% to form a casting solution. Inject the casting solution into the groove mold, and place the bottom of the mold in liquid nitrogen to solidify the casting solution. After it is completely solidified, take it out of the mold and place it in a freeze-drying environment to obtain a pore diameter range of 40-50 μm and a pore wall thickness. Through-hole membranes in the range of 1 to 2 μm. Control the height of the casting solution to set the thickness of the perforated membrane to 10mm, the filter layer is silk fibroin particles, and its thickness is 15mm, and the mesh number of the metal screen is 80 mesh to obtain a water treatment membrane module. Tests show that the water treatment membrane module of the present invention...

Abstract

The invention relates to a water purification component and belongs to the field of water treatment equipment. The water purification component mainly comprises a metal screen, a via-hole membrane, a filter layer and a filter barrel. A filter element herein is the via-hole membrane. The water purification component can treat water mainly via the filter element and the filter layer, and water purifying and filtering properties are improved. The water purification component is simple in structure and convenient to operate, the membrane is easy to detach and replace, and the water purification component is widely applicable to sewage emission treatment, drinking water purification and other professional fields.

Description

technical field [0001] The invention relates to a water purification treatment assembly, which belongs to the technical field of water treatment. Background technique [0002] With the rapid development of modern industry, many environmental problems have emerged, threatening human health. Among them, water pollution is the most serious problem facing human beings at present. In terms of water purification, two aspects must be achieved. On the one hand, it must be eliminated at the source, that is, to treat and discharge sewage, and on the other hand, it is to filter domestic water before use. . Therefore, water treatment and filtration devices play a very important role in the process of water purification. [0003] At present, there has been some research on the use of water treatment membranes for sewage treatment and filtration. For example, the application number is 201180021131.2, and the name of the invention is water filter components and filter elements. This docu...
