Abstract
The invention discloses an activated carbon fiber sintered filter element and its preparation method. The preparation method comprises the following steps: mixing ultrahigh molecular weight polyethylene and activated carbon fiber, pressing, sintering, and carrying out cooling molding. In comparison with the prior art, the invention has the following beneficial effects: the prepared filter element doesn't drop powder, has high strength which is 2-3 times higher than that of a common activated carbon powder sintered filter element and will flow out little black water at the beginning (a lot of black water will flow out when an original activated carbon powder filter element begins to be used); the prepared filter element has high flux and high water yield (under the pressure of 0.2MPa, flux of an activated carbon powder filter element of 10 inches is 6.6 L/min and the total water yield is 8-10 tons; but under the same condition, flux of the activated carbon fiber filter element is 8 L/min and water yield is 10-12 tons); and the prepared filter element has a good adsorption effect: a good effect of removing residual chlorine and impurities (residual chlorine removal rate of an activated carbon powder filter element of 10 inches is 50%, but residual chlorine removal rate of the activated carbon fiber product is 65-70%).
