Tap water supply pipe secondary pollution disposition and water outlet drinking water quality improving device

Abstract

The invention discloses a tap water supply pipe secondary pollution disposition and water outlet drinking water quality improving device, which comprises four stages of filter cores, wherein each stage of filter cores consists of limited mass parts of filter raw materials, so that the tap water is subjected to grading filtration; various trace elements required by the human body can be supplemented. The water purification device formed by using a water purifier can obviously reduce the aerobic bacterial count in the tap water and the contents of nitrate, chlorite, chlorate, chloride, sulfate and total dissolved solids; the turbidity of the tap water can be reduced. The water purification device formed by using the water quality improving device has the advantages that the water quality activity is enhanced; various trace elements required by the human body can be remained and supplemented; the constitution of people is improved; the immunity is enhanced; the service life is long; the water is used immediately after being released; the water quality reaches the drinking water standard; the water discharging quality is great; the maintenance is convenient; the reverse and forward flushing can be realized; economic performance and practicability are realized; the applicability is high.

Description

technical field

[0001] The invention belongs to the technical field of water treatment, and in particular relates to a secondary pollution treatment of tap water supply pipes and a drinking water quality enhancer at a water outlet. Background technique

[0002] At present, the use of tap water in my country is mainly used as domestic water. The tap water industry is outdated, and the ability to treat seriously polluted water bodies is limited, and some harmful substances cannot be removed; and because tap water is transported to thousands of households through long pipelines , Secondary pollution of pipelines is also inevitable. In cities, 20% of the water supply cannot meet the standard, and in rural areas, nearly 50% of the water supply cannot meet the standard. The test results for 490 pure water samples showed that only 28.82% of all the indicators were qualified, the total number of colonies and coliform bacteria exceeded the standard rate were 49.06% and 27.31%, and the...
