The pure water processing method of a purification apparatus of pure water according to claim 5, characterized in that: the water hardness detector (31) detects the water hardness in the main liquid inlet water pipe (3), and if the water hardness of the standby water reaches the standard, the standby water is directly conveyed into the degerming cavity (23) through the second liquid inlet water distribution pipe (4) for degerming and then is discharged; if the hardness of the water quality of the water to be used exceeds the standard, the water to be used is conveyed into a water softening box (1) through a first liquid inlet water distribution pipe (11) for water quality softening, and then the water is discharged after degerming treatment;
the method specifically comprises the following steps:
step one, closing a first switch valve (111) and a second switch valve (41), conveying water to be used into a liquid inlet main water pipe (3), and detecting the water to be used by a detection electrode (311) at a water quality hardness measuring instrument (31) at the tail end of the liquid inlet main water pipe (3), so that the water quality hardness measuring instrument (31) detects a hardness result of the water to be used;
step two, if the hardness of the water to be used is detected to exceed the standard, a signal output end of the water quality hardness measuring instrument (31) sends an electric signal to a first switch valve (111) to open the first switch valve (111), standby water in a liquid inlet main water pipe (3) enters a water body softening box (1) through a first liquid inlet water distribution pipe (11), when standby water flows through a mixing channel (14) of a liquid inlet channel (12) of the water body softening box (1), a liquid medicine introducing pipe (6) introduces liquid medicine into the water body softening box (1) from the outside, the liquid medicine is sprayed into the mixing channel (14) through a liquid medicine outlet pipe (61) to be mixed with the standby water, and the standby water is softened by reaction between the standby water and the liquid medicine in a softening channel (15); then flows into a filter cavity (21) in the water body sterilization filter box (2) to filter solid sediment in the water to be used; finally, the filtered water to be used flows into the sterilization cavity (23) and flows out from the water outlet pipe after being sterilized and sterilized;
and step three, if the hardness of the water to be used is detected to reach the standard, the signal output end of the water quality hardness measuring instrument (31) sends an electric signal to the second switch valve (41), so that the second switch valve (41) is opened, and the water to be used in the liquid inlet main water pipe (3) enters the sterilizing cavity (23) in the water body sterilizing filter box (2) through the second liquid inlet water dividing pipe (4) to be sterilized and then flows out of the water outlet pipe.
