Abstract
The invention involves a filter element, particularly involves a structure filter element removing arsenic in drinking water and its preparation methods. The invention weighs the raw materials according formula in preparation process, puts them in mold after mixes and stirs uniformly; the materials are sintered and molded in high temperature and demoulded after cooled to room temperature, then the porous tubular structure filter with required wall thickness and height. The structure filter element removing arsenic in drinking water in the invention can purify drinking water, simultaneously remove harm effects of overproof arsenic in drinking water to humans and is suitable for families terminal drinking water processing. It is checked that the drinking water arsenic removal rate of the structure filter is more than 95%.
Description
technical field [0001] The invention relates to a filter element, in particular to a structural filter element for removing arsenic in drinking water and a preparation method thereof. Background technique [0002] With the rapid development of industry and agriculture, my country's water resources have been severely damaged. More and more industrial waste water is discharged into rivers and lakes, destroying our ecological environment. The extensive application of pesticides and insecticides and the indiscriminate discharge of domestic waste have resulted in poor groundwater quality and the production of many harmful substances in the water. Water pollution has increasingly become a serious problem affecting people's lives. [0003] Arsenic is one of the most toxic elements. Inorganic arsenic compounds are confirmed human carcinogens recognized by many authoritative organizations such as the International Cancer Institute under the World Health Organization, the American ...
