Abstract

The invention provides a preparation method of a filtering medium for removing an antibiotic-sulfamethoxazole in drinking water. The method comprises the following steps: (a) mixing ultra high molecular weight polyethylene powder, activated carbon powder, micron molecular sieve powder, nanometer molecular sieve powder and a foaming hole agent to obtain a mixture, wherein the weight ratio of the ultra high molecular weight polyethylene powder to the activated carbon powder to the micron molecular sieve powder to the nanometer molecular sieve powder to the foaming hole agent is (200-300) to (100-200) to (50-100) to (50-100) to (50-100); and (b) putting the mixture obtained in (a) into a mold, pressing, sintering, and cooling, wherein the pressing pressure is 0.4-1MPa, the sintering temperature is 200-240 DEG C, the sintering time is 90-150min, and the cooling temperature is 40-60DEG C. In the invention, the filtering medium prepared by a synergistic effect of the raw materials and matching with special sintering temperature, pressure and cooling temperature has high removal rate for the antibiotic-sulfamethoxazole in the drinking water. The method is simple, and proved by tests, the filtering medium has a removal rate up to 98.0% and above for the antibiotic-sulfamethoxazole in the drinking water.

Description

technical field [0001] The invention relates to a filter medium for removing the antibiotic sulfamethoxazole in drinking water and a preparation method thereof, a filter element, a water purification device and a water dispenser composed of the filter medium. Background technique [0002] The Institute of Microbiology, Chinese Academy of Sciences and Shenzhen Huada Fund Research Institute found that the human intestinal tract has the highest proportion of drug resistance genes, and the relative number of 70 drug resistance genes is the largest in the Chinese intestinal tract. Spaniards have an average of 49, and the Danes have the least number of 45. In fact, Denmark is a country that strictly controls the use of antibiotics, strictly restricting doctors' prescriptions, and at the same time, since 1998, it has banned the use of all non-therapeutic antibiotics on animals, and then introduced stricter regulations to control people's use of animals antibiotic. Similarly, the ...
