Purifying equipment for domestic water

Abstract

The invention discloses purifying equipment for domestic water. The purifying equipment comprises an active-carbon filtering chamber, wherein one side of the bottom end of the active-carbon filtering chamber is provided with a tap-water inlet, one side of the top end of the active-carbon filtering chamber is communicated with a biological manganese-sand filtering chamber, an ultrafiltration-membrane filtering chamber, an ultraviolet disinfection chamber and a clean-water pool; the middle parts of the top ends of the active-carbon filtering chamber, the biological manganese-sand filtering chamber and the ultrafiltration-membrane filtering chamber are respectively provided with a first spraying head, a second spraying head and a third spraying head, and the middle parts of the bottom ends of the active-carbon filtering chamber, the biological manganese-sand filtering chamber and the ultrafiltration-membrane filtering chamber are respectively connected with a first draining valve, a second draining valve and a third draining valve; and the top end of the clean-water pool is connected with a clean-water connecting main pipe which is respectively communicated with the first spraying head, the second spraying head and the third spraying head by a first backwashing valve, a second backwashing valve and a third backwashing valve. The purifying equipment disclosed by the invention has the advantages that the structure is simple, the operation is convenient, the purifying effect is good, and batched purifying treatment can be carried out on tap water; and backwashing can be carried out respectively on all the filtering chambers by the backwashing valves, so that high-efficiency purifying effect can be maintained all the time.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to domestic water purification equipment. Background technique [0002] At present, with the development of society, urban residents and the vast majority of rural residents use tap water as domestic water, including drinking water and washing water. However, in recent years, due to the serious pollution of the environment, there are heavy metals, dissolved organic matter, bacteria and other pollutants in natural water bodies, and the production of tap water still uses traditional coagulation, filtration and disinfection processes, which cannot effectively remove the above pollutants in water ; In addition, tap water also contains secondary pollutants such as disinfection by-products such as chloroform and microorganisms brought when flowing through the tap water network pipe, which cannot meet the standard of healthy drinking. [0003] The current household water purifi...

Problems solved by technology

However, in recent years, due to the serious pollution of the environment, there are heavy metals, dissolved organic matter, bacteria and other pollutants in natural water bodies, and the production of tap water still uses traditional coagulation, filtration and disinfection processes, which cannot effectively remove the above pollutants in water In addition, tap water also contains secondary pollutants such as disinfection by-products such as chloroform and microorganisms brought when it flows through the tap water network pipes, which cannot meet the standard of healthy drinking.

[0003] The current household water purification equipment is usually a water dispenser, and its existing problems are: 1. The process is complicated and maintenance is difficult; 2. The decontamination ability is poor; 3. It is inconvenient to use for tap water purification.
