Referring to Figure 2 describes a multi-functional filter sheet having a suction filtration and disinfection function according to an aspect of the present invention, the multi-functional filter sheet 20 shown in Figure 2 (a) is shown in Figure 2 (b) As shown, the outer surface includes the activated carbon-containing sheet 10b and the inner surface of the copper-containing sheet 10a.

The activated carbon-containing sheet 10b is formed by the technique shown in FIG. 1, and is composed of activated carbon particles 1 and a fiber nonwoven fabric 2, which will be described in detail. Activated carbon particles in the nonwoven fabric (2) by mixing the organic polymer fibers (2) with the molded activated carbon particles (1), which can be easily obtained without hindering them, into the model and heating to 100 to 300 ℃ (1) is bonded to form a constant sheet shape of about 5-50mm in thickness. The organic polymer fibers are easily melted polyether (PE) or polyester (PET) with a density of 500-1000 g / m ² and a length of 5 to 10 cm for maintaining the shape of the sheet and proper mixing with the formed activated carbon particles (1). Preference is given to using. There are over-density filter if the density of 500g / m if the less than ² has been difficult for the shape retaining sheet in the inlet in the polluted water can not be made better the filtering of contaminants, 1000g / m ² greater than Efficiency may be reduced. Therefore, when the contaminated water contains a lot of fine ocher, etc., the density is high, and when there is a large amount of sludge, it is possible to set the density somewhat lower. In addition, 250-500 g / m of activated carbon particles (1) formed in consideration of the density of the organic polymer fiber material in consideration of the performance of the adsorption of contaminants in an appropriate range, durability in the inflow of contaminated water, usage time, etc. It is preferable to add in the range of ² and to heat-mold.

The copper-containing sheet 10a is a nonwoven fabric made of a fiber material capable of adsorbing copper having an antibacterial and deodorizing effect in a 5-10% by weight copper solution in which copper salts such as copper sulfate, copper nitrate or copper chloride are dissolved in distilled water. The weight ratio was 1: 3 to 1:20, which was deposited at room temperature for 24 hours, in which about 0.1-20% by weight of copper was adsorbed onto the nonwoven fabric. The reason that the weight ratio of the copper solution is 5 to 10% by weight is preferable because uneven deposition of copper may be formed on the nonwoven fabric when the copper solution is 5% by weight or less, and in the case of 10% by weight or more, the adsorption efficiency is high. Because I do not lose. It is preferable in the adsorption efficiency of copper that the weight ratio of a nonwoven fabric and a copper solution shall also be 1: 3-1: 20. In addition, it is preferable to allow about 0.1-20% by weight of copper to be adsorbed onto the nonwoven fabric of the copper-containing sheet 10a of the present invention in terms of antibacterial and deodorizing effect and economic efficiency. In addition, in the case of the fibrous nonwoven fabric, the thickness is about 5-50mm and is preferably made of protein-based fibers or acrylic fibers excellent in copper adsorption, but is not limited thereto.
