Description

technical field [0001] The invention relates to drinking water filtering technology, in particular to a drinking water filtering device and filtering method based on graphene technology. Background technique [0002] Water is the source of life, and access to safe drinking water is a basic need for human survival. Drinking water refers to drinking water and domestic water for human life. my country's current "Hygienic Standards for Drinking Water" (GB5749-2006) stipulates strict hygienic requirements for drinking water quality, namely: good sensory properties: transparent, colorless, no peculiar smell and odor, no visible matter; popular Pathologically safe: no pathogenic microorganisms and parasite eggs; chemical composition harmless to humans: chemical substances contained in water will not cause acute poisoning, chronic poisoning or long-term harm to the human body. However, the current drinking water safety situation in my country is very severe. With the rapid advance...
