Glacial water treatment method

Abstract

The invention discloses a glacial water treatment method, which comprises: (1) detecting water quality of water in a raw glacial water storage device, wherein if the water quality meets a preset requirement, a step (3) is executed directly, or a step (2) is performed; (2) transferring water from the raw glacial water storage device into a pretreatment unit for pretreatment, and then into a reverse osmosis treatment unit for reverse osmosis treatment, returning the water subjected to reverse osmosis treatment to the raw glacial water storage device to mix the water with raw water, and continuing to perform the step (1); and (3) transferring the water from the raw glacial water storage device to the pretreatment unit for pretreatment, and performing further purification treatment. The glacial water treatment method provided by the invention can select proper treatment steps according to the change of water quality at a water collecting point, realize simple product and assure product quality.

Description

technical field [0001] The invention relates to a treatment method for glacier water. Background technique [0002] Existing glacier water treatment methods usually include coarse filtration (sand filtration, carbon filtration)→ultrafiltration (0.15μm)→ozone sterilization (0.6mg / L)→Sihe→filling machine (disinfection, washing, filling, pressing, etc.) cover). The glacier water is filtered through a sand filter and a carbon filter, and then through an ultrafiltration system to remove part of the micro-suspended solid medium that cannot be removed by the aforementioned filter, so that the glacier water can be further purified, and then ozone is added to the treated water to make it The water quality meets the hygienic requirements for drinking and filling, and it is filled with a four-in-one filling machine. [0003] CN101250012A discloses a treatment method for glacier water. The method is to pass natural glacier water through a pretreatment unit A, an ultrafiltration unit B...

AI Technical Summary

Problems solved by technology

[0004] However, it is well known that the water quality at the water intake point varies according to the season, and the water quality at the water intake point is not stable

Simple ultrafiltration does not guarantee product quality

However, the method in CN101250012A is too cumbersome and impractical when the water quality at the water intake point is good, resulting in long production cycle and energy waste
