Description

technical field [0001] The invention relates to the field of drinking water systems, in particular to an automatic drinking water system for fingerprint recognition. Background technique [0002] In a broad sense, water resources on the earth refer to the total amount of water in the hydrosphere. Including surface water and groundwater controlled by humans and directly available for irrigation, power generation, water supply, shipping, aquaculture, etc., as well as rivers, lakes, wells, springs, tides, harbors, and aquaculture waters. Water resources are an important natural resource indispensable to the development of the national economy. In many parts of the world, the demand for water has exceeded the capacity of water resources, and many regions are also on the verge of water imbalance. [0003] Water is an essential and important material for the survival of human beings and all living things, and an extremely precious natural resource that cannot be replaced by indu...

Problems solved by technology

[0004] At present, the composition of urban pollution is very complex. In addition to heavy metals, the polluted waters also contain many harmful residues such as pesticides, fertilizers, and detergents. Even if the tap water is boiled, the above residues are still persistent. Boiling water increases the concentration of harmful substances, reduces the content of dissolved oxygen that is beneficial to human health, and also increases carcinogens such as nitrite and chloroform. Therefore, the safety factor of drinking boiled water is not high.

According to the latest data, at present, only 23% of residents' drinking water in major cities in my country meets the hygienic standards, and the passing rate of drinking water in small towns and rural areas is even lower.
