Problems solved by technology

Studies have shown that 77% of synthetic musk enters domestic sewage after use, enters sewage treatment plants through the sewage system, and re-enters the environment with the reuse of sewage sludge, affecting human health
[0005] Conventional water treatment processes are difficult to remove artificial musk from drinking water; air flotation, oxidation and other equipment are complex and inconvenient to use; reverse osmosis is costly and wastes water, and the concentrated solution produced is more difficult to handle and easy to produce secondary pollution

Abstract

The invention discloses a preparation method of a filter medium used for removing artificially synthesized musk in drinking water, which comprises the following steps of: a) mixing the raw materials containing activated carbon fiber powder, ultrahigh molecular weight polyethylene powder, nanometer silicon oxide powder, active alumina powder and a gas generation agent, wherein, the weight ratio ofthe activated carbon fiber powder, the ultrahigh molecular weight polyethylene powder, the nanometer silicon oxide powder, the active alumina powder and the gas generation agent is (100-300): (200-450): (80-200): (80-200): (50-150); and b) suppressing, sintering and cooling the obtained mixture in a mould. The prepared filter medium has high removal rate on the artificially synthesized musk in the drinking water, is suitable for being used in the drinking water polluted by the artificially synthesized musk, and can be used for avoiding the damage of the artificially synthesized musk on human bodies, and is simple in use and low in cost; and in addition, a filter element instead of a powder body is used, thus post-treatment is not needed; and the preparation method is suitable for treatinghome terminal drinking water; and through the detection, the removal rate of the filter medium on the artificially synthesized musk in the drinking water is over 95%.

Description

technical field [0001] The invention relates to a filter medium for removing artificially synthesized musk in drinking water and a preparation method thereof, a filter element, a water purification device and a water dispenser composed of the filter medium. Background technique [0002] With the improvement of people's living standards, the demand for musk is increasing year by year. In addition, the random hunting and killing of animal musk deer has led to the depletion of natural musk resources, which is far from meeting the needs of the society. In order to promote the protection of animal musk deer, People have obtained a class of compounds with a musky smell through artificial synthesis methods, i.e. a substitute for natural musk - artificial musk. [0003] As an alternative fragrance, synthetic musk is widely used in the daily chemical industry. Due to its continuous input into the environment, the concentration of some typical compounds such as Gala musk and Tuna musk...
