Problems solved by technology

The use of water purifiers to coagulate industrial wastewater and urban sewage is one of the most commonly used methods in water treatment, and it is also an important means to eliminate pollution and protect the environment. Commonly used water purifiers are mainly chemical water purifiers and biological water purifier, but because its chemical water purifier contains a large amount of chloride ions, although the water purification effect is good and the water purification ability is strong, it will also produce a large amount of chloride ion residues in the water. It consumes a long time, which is not conducive to the rapid development of industrial development. Therefore, the existing technology needs further improvement

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a composite water purifier and a preparation method thereof. Background technique [0002] With the rapid advancement of my country's industrialization process, environmental pollution, especially water pollution, has become increasingly serious, affecting people's health and living environment. The use of water purifiers to coagulate industrial wastewater and urban sewage is one of the most commonly used methods in water treatment, and it is also an important means to eliminate pollution and protect the environment. Commonly used water purifiers are mainly chemical water purifiers and biological water purifier, but because its chemical water purifier contains a large amount of chloride ions, although the water purification effect is good and the water purification ability is strong, it will also produce a large amount of chloride ion residues in the water. The time of c...
