Water purification device for purifying raw water

Abstract

The invention relates to filter equipment and particularly relates to a water purification device for purifying raw water. The water purification device comprises a filter unit and disinfection equipment and further comprises a backwashing device, wherein the filter unit sequentially comprises a quartz sand filter, an active carbon filter, a precision filter and reverse osmosis membrane equipment; a pressurizing pump is arranged between the precision filter and the reverse osmosis membrane equipment; the surface diameters of reverse osmosis membranes used by the reverse osmosis membrane equipment are 1-10nm; the filter unit is provided with two outlets, one of which is connected with the inlet of the disinfection equipment while the other one of which is connected with the backwashing device; and the outlet end of the disinfection equipment is provided with a heating device. By means of multi-stage filtration and then ultraviolet and ozone disinfection, impurities in water are thoroughly removed, so that the water reaches the standard of drinking water. The backwashing device of the equipment is used for washing the filter unit by reversed purified water, so that deposited impurities can be effectively removed and the service life of a filter element is prolonged.

Description

Technical field [0001] The invention involves filtering equipment, especially a water purification device for raw water purification. Background technique [0002] People ’s life use tap water sometimes contains various particulate matter or other turbid sources such as fine sand and rust, which will also remain chlorine, pesticides, lead and other harmful ingredients. MoreoverHarmful substances are mixed into the river in the river. Therefore, the water purifier is generally widely used for purification of tap water before using it.The tap water (raw water) becomes a water purification by purifying the internal purification material and flows out of the water purifier. [0003] At present, most of the water purifiers used in the applicable households are mostly purified materials for PP cotton, coal -made charcoal, cotton beam, activated carbon, etc., and PP cotton is used to filter granular substances in tap water or granules that become other turbid sources.As well as solid in...
