Abstract

The invention discloses a preparation method of a filter medium for removing methyl tertiary butyl ether in water, comprising the following steps: a) mixing raw materials containing ultra-high molecular weight polyethylene (PE), activated carbon, 10X-type molecular sieve powder and pore forming agent at the following weight ratio: 220-400 parts of the ultra-high molecular weight PE, 100-120 partsof the activated carbon, 80-120 parts of the 10X-type molecular sieve powder and 90-120 parts of the pore forming agent; and b) pressing, sintering and cooling the mixture obtained in step a) in a die. The invention also discloses a filter medium prepared by the preparation method, a filter element utilizing same, a water purifying plant and a water dispenser. Compared with the prior art, the invention has the advantages that the proposed technical scheme can remove the methyl tertiary butyl ether in water, and the removal rate is above 96%, so that water quality is improved. The method is simple, the raw materials for preparing filter medium have wide resources and low cost.

Description

technical field [0001] The invention relates to a filter medium for removing methyl tert-butyl ether in water, a preparation method thereof, a filter element using the filter medium, a water purification device and a water dispenser. 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] The structural formula of methyl tert-butyl ether is as follows: [0004] [0005] The abbreviation of methyl tert-butyl is MTBE. People are exposed to methyl tert-butyl ether through contaminated drinking water, and there is a potential hazard. The fat-soluble prope...
