A multifunctional full-effect direct drinking water system

Abstract

The invention discloses a multifunctional full-effect direct drinking system, which has functions of multiple-circulation sterilization and disinfection, on-line sterilization fresh-preservation, provides water good in quality and taste, and can intensively provide lots of direct drinking water. The system comprises an electrical control device (30), as well as a raw water tank (1), a raw water pump (2), a multi-media filter (3), an activated carbon filter (4) , a water softener (5), a medicine adding device (6) for the water softener (5), a medicine cleaning device (7), a security filter (8), a high pressure pump (9), a reverse osmosis device (10) with a plurality of RO films, a purified water tank (11), an ultraviolet sterilization device (12), a frequency conversion feed water pump (13), a rear-mounted precision filter (14), a rear-mounted adjuster (15), and a net water end (16), which are connected sequentially, so as to form a direct drinking water making pipe, wherein an ozone mixer (19) and an ozone machine (18) are arranged on the pipe between the reverse osmosis device (10) and the purified water tank (11); the net water end (16) is connected with the purified water tank (11) through a backwater filtering device (17) so as to form a backwater circulation sterilization and disinfection pipeline. Therefore, the drinking system can be applied to the field of direct drinking water.

Description

technical field

[0001] The invention relates to a multifunctional full-effect direct drinking water system. Background technique

[0002] Municipal units, schools, hospitals, office buildings, military camps, hotels, villas, airports and other places generally need to provide pure drinking water for people's daily needs. The traditional water supply process has a single sterilization method, the sterilization is not thorough, and it is difficult to meet the standard for direct drinking. Existing purified water is generally supplied in the form of a single machine or multiple supplies from one machine, which is difficult to meet the demand for concentrated large-scale supply of direct drinking water. The existing direct drinking water system does not have the function of pipeline circulation sterilization and disinfection. In the case of some water supply pipe networks or water terminals without water for a long time, there will be stagnant water in the pipe network, which i...
