Abstract

The invention discloses a preparation method of a filter medium for removing anion synthetic detergent in water. The preparation method comprises the following steps: a) mixing raw materials containing polyethylene with ultrahigh molecular weight, active carbon, diatomite powder, boric sludge powder and hole forming agent, wherein the weight ratio of the polyethylene with ultrahigh molecular weight, the active carbon, the diatomite powder, the boric sludge powder and the hole forming agent is 200-350:50-100:50-100:50-100:50-120; and b) pressing, sintering and cooling the obtained mixture in amould. The invention also discloses the filter medium prepared according to the preparation method. Compared with the prior art, the invention can remove the anion synthetic detergent 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.

Description

technical field [0001] The invention relates to a filter medium for removing anion synthetic detergent 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] Most of the synthetic detergents in my country belong to the anionic surfactant type, mainly linear alkylbenzene sulfonate sodium (LAS). The use of synthetic detergents involves almost all aspects of industrial and agricultural production and family life. In the end, most of them form emulsified colloids and exist in wastewater. After the primary pollutant L...
