Ceramic nanofiltration membrane water purifier capable of realizing high-temperature sterilization

The invention relates to a ceramic nanofiltration membrane water purifier capable of realizing high-temperature sterilization. The ceramic nanofiltration membrane water purifier comprises a front filter, an adsorption activated carbon filter element, a ceramic ultrafiltration membrane filter element and a ceramic nanofiltration membrane filter element which are sequentially connected through pipelines, wherein the front filter is connected with a water inlet pipeline which can be connected with tap water or hot water; a produced water outlet of the ceramic ultrafiltration membrane filter element is connected with an ultrafiltration water outlet pipeline; a produced water outlet of the ceramic nanofiltration membrane filter element is connected with a nanofiltraiton water outlet pipeline. The ceramic nanofiltration membrane water purifier can be used for realizing high-temperature sterilization, thoroughly solving the problem of bacterial growth of the water purifier and providing ultrafiltration produced water, nanofiltraiton produced water and cleaning water as required and is convenient to use.
