Wherein, colloid substances, partial ion substances, dissolved gas, microorganisms and the like in the water are further removed through the polypropylene activated carbon filter element 9; the nanofiltration membrane filter core 10 further removes organic matters, chromaticity and partial soluble salts in water, so that the hardness of the water is reduced; the periodic table in the periodic table sterilizing filter element 11 releases +5 valence iodine ion after entering water, change the permeability of the cell, oxidize the active gene of bacterial cell and viral protein, combine with amino of protein, make it coagulate and denature and break its reproduction, destroy various pathogens and normal living environment of water body protozoa rapidly, kill the residual microorganism therein. The purified water after the treatment enters a variable-temperature water tank 17 through a one-way check valve 12, when the water temperature is lower than the set temperature, a temperature sensor 18 transmits the water temperature to a PLC (programmable logic controller) 20, and the PLC 20 controls a heating switch 14 to control a heating pipe 13 to heat so as to increase the water temperature; when the water temperature is higher than the temperature, the temperature sensor 18 transmits the water temperature to the PLC 20, and the PLC 20 controls the refrigerating switch 16 to control the refrigerating radiator 15 to refrigerate, so that the water temperature is reduced, and finally the water temperature reaches the set temperature; when the water temperature is regulated by the variable-temperature water tank, the heating switch 14 and the refrigerating switch 16 are simultaneously closed in time, and the work of the heating pipe and the refrigerating radiator is regulated, so that the temperature is maintained within the range of +/-3 ℃ of the set temperature. The temperature of the variable-temperature water tank is displayed in real time by a temperature display screen 19, and finally the constant-temperature water flows out from a purified water outlet 21. In addition, the PLC controller 19 controls the water inlet electromagnetic valve 2, the water inlet pump 4, the high-pressure pump 8 and the one-way check valve 12 to work.
