Description

Hollow fiber nanofiltration water purification device Technical Field The utility model relates to the technical field of domestic water purification treatment, in particular to a hollow fiber nanofiltration water purification device. Background At present, in the field of household domestic water purification, an ultrafiltration water purifier and a reverse osmosis water purifier are mainly arranged, the ultrafiltration water purifier does not need booster power equipment and power supply, no waste water is generated, the filter element updating cost is low, the water quality after the purification of the reverse osmosis water purifier is good, and almost all pollutants including anions and cations are removed. The ultrafiltration water purifier has the defects that the purified water quality is general and does not remove all anions and cations basically, the reverse osmosis water purifier has the defects that the water inlet needs to be increased and an external power supply is needed, a large amount of wastewater (reverse osmosis concentrated water) is generated, the filter element updating cost is high, and the reverse osmosis water purifier is not optimal solution for human health because all anions and cations and minerals and microelements beneficial to human bodies are removed. In summary, it is necessary to provide a hollow fiber nanofiltration water purification device which has good water purification, retains minerals and trace elements beneficial to human body, and meets the requirements of human body. Disclosure of utility model The utility model aims to provide a hollow fiber nanofiltration water purification device, which can improve the purification effect of domestic water, has good purification water quality, retains mineral substances and microelements beneficial to human bodies, and meets the requirements of human bodies. In order to achieve the above purpose, the hollow fiber nanofiltration water purification device comprises a water inlet pipeline, a first PP melt-blown filter, a front activated carbon filter, a second PP melt-blown filter, a hollow fiber nanofiltration membrane, a rear activated carbon filter and a water outlet pipeline, wherein the first PP melt-blown filter is connected with the water inlet pipeline, the front activated carbon filter is connected with the first PP melt-blown filter, the second PP melt-blown filter is connected with the front activated carbon filter, one end of the hollow fiber nanofiltration membrane is connected with the second PP melt-blown filter, the rear activated carbon filter is connected with the other end of the hollow fiber nanofiltration membrane, and the water outlet pipeline is connected with the rear activated carbon filter. The hollow fiber nanofiltration water purification device further comprises a wastewater drain pipe, wherein the wastewater drain pipe is connected with the hollow fiber nanofiltration membrane and is positioned at one end of the hollow fiber nanofiltration membrane away from the second PP melt-blown filter. Wherein, the filtration pore diameter of the hollow fiber nanofiltration membrane is the nanofiltration grade. When the hollow fiber nanofiltration water purification device is used, domestic tap water is input into the first PP melt-blown filter through the water inlet pipeline to be subjected to primary filtration, so that impurities with larger particles in the water are removed, then primary filtered water enters the front-mounted active carbon filter to be subjected to secondary filtration, organic pollutants and residual chlorine in the water are removed, then secondary filtered water enters the second PP melt-blown filter to be subjected to tertiary filtration, active carbon fragments generated by the secondary filtration are intercepted, suizhou tertiary filtered water enters the hollow fiber nanofiltration membrane to be subjected to membrane purification, the nanofiltration membrane can effectively remove organic and inorganic pollutants remained after the tertiary filtration, monovalent anions and cations are reserved in produced water through the membrane, other pollutants with divalent anions are trapped in concentrated water to be discharged as waste water, mineral substances and trace elements required by a human body are reserved, and finally the produced water of the hollow fiber nanofiltration membrane is subjected to final-stage filtration through the rear-mounted active carbon filter, so that domestic drinking water is acted after taste improvement, and the effect of the domestic drinking water is realized, the water purification effect for improving the domestic water quality is good, and the requirements for the human body are met, and the mineral substances and trace elements are reserved.
