Abstract

The invention discloses a compound filter material for soft water and a preparation method of the compound filter material. Aiming at the water quality characteristics of hard water, materials such as active carbon granules, medical stone, silica sand, calcite and carborundum are selected to replace traditional ion exchange resin and are assisted by the synergistic effect of a chemical reagent, so as to carry out joint coordination treatment in the treatment softening process of hard water. The compound filter material has an efficient water softening effect; the preparation method is simple and convenient; the prepared filter material particles do not easily breed mold and are high in safety performance, high in industrial degree, and outstanding in economic benefits; and the hard water treatment cost is effectively reduced.

Description

technical field [0001] The invention relates to a water treatment filter material and its preparation, in particular to a composite filter material for soft water and its preparation method. Background technique [0002] The problem of water quality is a major focus of people's life in society. At present, the water quality in some parts of the country and abroad is relatively hard. The hardness of water is the total concentration of cationic calcium and magnesium ions contained in it. The existing drinking water filter intelligently filters water Impurities such as floating matter, sediment, rust or peculiar smell such as bleaching powder smell, muddy smell, rust smell, etc., but a large amount of calcium and magnesium ions cannot be filtered and absorbed, and the total concentration of calcium and magnesium ions is too high, which is harmful to the human body. Compared with tap water, soft water has a very obvious taste and feel. Soft water has high oxygen content and low ...
