Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a sterile water treatment device comprises a softener 1, a security filter 2, a main electromagnetic valve 3, a high-pressure pump 4, a reverse osmosis filter 5, a pure water tank 6, an ozone generator 7, a pure water pump 8, a precision filter 9, a sampling water receiving port 10, a circulating electromagnetic valve 11 and a flushing electromagnetic valve 12, and is characterized in that: the softener 1, the security filter 2, the main electromagnetic valve 3, the high-pressure pump 4, the reverse osmosis filter 5 and the pure water tank 6 are connected through pipelines to form a pure water preparation system;
