Abstract

The invention discloses a preparation method of a filter medium for removing diethylstilbestrol in water. The preparation method comprises the following steps: a) mixing raw materials containing ultrahigh molecular weight polyethylene, active carbon, sepiolite powder, attapulgite powder and hole forming agent, wherein the weight ratio of the ultrahigh molecular weight polyethylene, the active carbon, the sepiolite powder, the attapulgite powder and the hole forming agent is 200-350:50-100:40-100:50-100:50-120; and b) pressing, sintering and cooling the obtained mixture in a mould. The invention also discloses the filter medium prepared according to the preparation method. Compared with the prior art, the invention can remove the diethylstilbestrol in the water with a removal rate of over 95 percent so as to achieve the aim of improving the water quality; in addition, the method is simple, and the raw materials for preparing the filter medium are widely available and have low cost. Thetechnical scheme is in particular applicable for the treatment of drinking water polluted by the diethylstilbestrol.

Description

technical field [0001] The invention relates to a filter medium for removing diethylstilbestrol 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] One of the most diverse types of environmental endocrine disruptors is an endocrine disruptor with estrogenic activity. There are mainly natural estrogens, industrial products (pesticides), surfactants, titanates, drugs (diethylstilbestrol), etc. Most of them tend to accumulate in humans and other organisms for a long time, interfering with the normal endocrine me...
