Problems solved by technology

[0002] Water quality is a major focus of people's life in society. At present, more and more families in China and some foreign countries choose water purification equipment for household water purification treatment. Most water purifiers use filter element + filter material for purification. In the treatment of water, the filter material actually plays a very important role in the deep purification process of drinking water, but the existing filter material has a short life on the one hand, and on the other hand, there are substances that are harmful to disinfection by-products such as halogenated hydrocarbons. The removal effect is not good

Abstract

The invention discloses preparation of a compound filter material for removing drinking water disinfection by-products. The compound filter material is prepared by the steps of mixing the following filter material raw materials: active peanut shell carbon, modified activated carbon, far infrared sintering balls, quartz sand, ceramisite filter materials, asbestos and garnet according to a certain proportion, and supplementing with a synergistic effect of chemical treatment agents such as a degerming agent to prepare the compound filter material. The compound filter material carries out joint coordination treatment during a water quality purification process, has a high-efficient water purification effect, and especially has a better effect on removing halogenated hydrocarbon of the drinking water disinfection by-products, the adsorption saturation of the filter material is remarkably improved, the service life and the replacement cycle of the filter material are prolonged, the preparation method is simple and convenient, the prepared filter material particles cannot breed mycete easily, and the safety performance is high.

Description

technical field [0001] The invention relates to a water treatment filter material and its preparation, in particular to the preparation of a composite filter material for removing disinfection by-products of drinking water. Background technique [0002] Water quality is a major focus of people's life in society. At present, more and more families in China and some foreign countries choose water purification equipment for household water purification treatment. Most water purifiers use filter element + filter material for purification. In the treatment of water, the filter material actually plays a very important role in the deep purification process of drinking water, but the existing filter material has a short life on the one hand, and on the other hand, there are substances that are harmful to disinfection by-products such as halogenated hydrocarbons. The removal effect is not a good problem. [0003] Therefore, how to seek the preparation of a composite filter material ...
