Water purification technology for household water purification equipment

Abstract

The invention relates to the technical field of water purification equipment, in particular to a water purification technology for household water purification equipment. The technology comprises the following steps of primary ceramic filtration, secondary ultraviolet disinfection, third-stage activated carbon fiber (ACF) filter element filtration and fourth-stage ultraviolet filtration disinfection; the four stage filtration technology is adopted, according to the operating characteristics of a household water purifier, the water purifier has the capacities of comprehensively controlling harmful microorganisms and sewage blocking and reserving mineral substances of drinking water, harmful substances are removed to the maximum extent, the healthy property of water is improved best, the direct drinking level is achieved, power is not additionally added, full flow filtration is achieved, water conservation is achieved, and the environmental protection and energy conservation requirements are met.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water purification process of household water purification equipment. Background technique [0002] With the development of social industrialization and the geometric increase of automobiles and other means of transportation, a large amount of industrial waste water and automobile exhaust are produced, resulting in man-made pollution and the existence of smog. The water quality of the reservoir is adversely affected by the rain falling, and the water quality of the tap water itself is not optimistic. At the same time, there are also some problems in the secondary water supply tank, especially the national standard GB5749-2006 of the "Drinking Water Hygienic Standard" has special regulations on the total number of colonies and two worms. Around these problems, household water purifiers mainly adopt the filtration technology of reverse osmosis and ultrafiltr...

AI Technical Summary

Problems solved by technology

[0006] 2) The use of too many activated carbon combinations and water tank devices can easily lead to secondary pollution of microorganisms and reduce the service life of reverse osmosis

[0007] 3) Replace the filter element, especially the pre-filter element more frequently

[0008] In addition, household water purifiers using ultrafiltration technology mainly use PP cotton filtration + ultrafiltration machine + activated carbon and other processes. Although the water production rate is high, but also due to the above reasons, microbial problems are more serious. The filter element is more frequent
