Problems solved by technology

[0004] The traditional water treatment process of the waterworks has no obvious removal effect on ibuprofen and clofibric acid; photocatalysis, electrochemistry, ozone machine ultrasonic technology, etc. are cumbersome to operate and are not suitable for terminal deep water purification; the removal effect of RO membrane is good, but Wastewater consumes electricity and costs high, and the discharged concentrated solution is not easy to handle, which is easy to cause secondary pollution

Abstract

The invention provides a preparation method of a filtering medium for removing ibuprofen and clofibric acid in drinking water. The preparation method comprises steps as follows: a), ultra-high molecular weight polyethylene powder, activated carbon powder, attapulgite powder, sepiolite powder and a pore forming agent are mixed in the weight ratio being (200-300):(50-100):(100-200):(100-200):(50-100), and a mixture is obtained; b), the mixture obtained in the step a) is pressed, sintered and cooled in a die, wherein the pressing pressure is 0.4 MPa-1MPa, the sintering temperature ranges from 200 DEG C to 245 DEG C, the sintering time lasts for 90-150 min, and the cooling temperature ranges from 40 DEG C to 60 DEG C. The filtering medium prepared at a specific sintering temperature and cooling temperature under specific pressure has a high removal rate for ibuprofen and clofibric acid under the synthetic function of the raw materials, the method is simple, and a detection result shows that with the adoption of the filtering medium, the removal rate of ibuprofen and clofibric acid in the drinking water is higher than 98.0%.
