Problems solved by technology

[0006] However, in addition to insoluble impurities, bacteria and viruses, organic matter, and heavy metal ions, the pollutants in drinking water sources also have water body odor caused by the decomposition of animal carcasses, the physical volatilization and dissolution of organic matter, the dissolution of soluble harmful gases in the external air, and the residual bleaching powder. The method of ceramic filter element to remove the odor of water body is to adsorb through the pores on its surface, and trap the odor molecules on the porous medium. However, the ceramic filter element has a very different capture rate for odorous gas, and it is impossible to better treat the odor with more complex components. , the treatment of the stench in the water by the ceramic filter element has always been an unresolved difficulty

Abstract

The invention discloses a composite filter element containing kieselguhr and starch and a manufacturing method of the composite filter element. By means of the composite filter element and the manufacturing method thereof, the problem that due to the fact that a ceramic filter element has quite different capture rates for foul gas, foul smell complex in constituent cannot be handled well is solved. According to the technical scheme, the composite filter element containing the kieselguhr and the starch is made of the modified kieselguhr, the mixed starch, cellulose acetate, molecular sieve raw powder, aluminum oxide, montmorillonite and a flocculating agent. The effect of removing the foul smell in water is achieved.

Description

technical field [0001] The invention relates to the field of filter elements, in particular to a composite filter element containing diatomite and starch and a preparation method thereof. Background technique [0002] Water, as the source of life, is a necessity in our lives. With the improvement of living standards, we have higher and higher requirements for living water quality. worsening trend. Nowadays, a filter is usually installed under the household faucet, which can effectively intercept bacteria and absorb organic matter and heavy metal ions remaining in the water, improve the quality and taste of drinking water, and retain the trace elements necessary for the human body. At present, there are two types of faucet water purification filter elements on the market: hollow fiber membrane filter elements and ceramic membrane filter elements. Although the hollow fiber membrane filter has high flux and low production cost, the hollow fiber membrane increases with time, a...
