Problems solved by technology

Of course, the amount of these drugs is very small, and it is precisely because of their small content, generally around 0.01mg / L, that they are difficult to remove, and they can flow into the drinking water source of another city through the city's sewage treatment equipment. Repeatedly, human beings drink such water for a long time will have adverse effects

Abstract

The invention discloses a preparation method of a filter medium for removing estrogen medicine from water, comprising the following steps: (a) mixing raw materials of polyethylene with super-high molecular weight, active carbon, zeolite powder, concave-convex barstone powder, molecular sieve powder and foaming agent in the weight ratio of 240-360:50-100:40-80:40-80:50-100:100-150; and (b) pressing, sintering and cooling the prepared mixture in a mould. The invention also discloses a filter medium prepared by the method. The invention has the advantage that the technical scheme can remove a trace amount of estrogen medicine from water with the removal rate of 95% above.

Description

technical field [0001] The invention relates to a filter medium for removing estrogen drugs in water and a preparation method thereof. Background technique [0002] The rapid development of industry and agriculture has led to serious damage to water resources. Industrial wastewater is discharged into rivers and lakes, pesticides, insecticides, etc. are used in large quantities, and domestic garbage and domestic wastewater are discharged indiscriminately. As a result, many harmful substances are produced in the water. Water pollution has increasingly become a serious problem affecting people's lives. [0003] Scientists in the United States recently analyzed water samples from 139 rivers and found "estrogen replacement drugs, ibuprofen, insecticide sprays, birth control pills, sunscreens in sunscreen, mouthwashes, antibacterial soaps, detergents, etc. "There are hundreds of medicinal ingredients, among which there are a large number of antibiotics, and the medicinal effect ...
