Embodiment 1

[0035] The demand for pure water in the field of industrial production is increasing day by day. Production processes such as CNC wire cutting high-end equipment or sheet metal spraying use a large amount of pure water every day, and have strict requirements on water quality. Once the water quality does not meet the standard, the quality of the finished product will be significantly affected. In the past The commonly used bottled pure water is expensive per liter and high in transportation costs. Each time it is used, it needs to wait for distribution. It is gradually replaced by reverse osmosis equipment. The current water purification system is designed for municipal tap water. In order to reduce costs, it is only based on conventional water quality. The design did not take into account the occurrence of salt tides in coastal areas in winter. When salt tides occur in winter, seawater intrusion will significantly increase the salinity of municipal tap water, resulting in a sign...

Abstract

The invention relates to the technical field of water quality purification, in particular to a water treatment system, comprising: a pretreatment unit suitable for communicating with a water inlet pipe, a reverse osmosis unit is communicated with the pretreatment unit through a first pipeline, a first conductivity meter is arranged on the second pipeline, the second pipeline is communicated with the upstream of the pretreatment unit through a dilution pipeline, the connection point of the dilution pipeline and the second pipeline is located at the downstream position of the conductivity meter,and the switch structure has a first state for communicating the pure water outlet with the pure water tank and a second state for communicating the pure water outlet with the upstream of the pretreatment unit. When the raw water quality is bad or the conductivity of the produced water does not meet the requirement due to salt tide or other reasons, the switch structure is switched to the secondstate, and the water is treated by the pretreatment unit and the reverse osmosis unit and then returns to the upstream of the pretreatment unit through the dilution pipeline to dilute the raw water, so that the quality of the produced water can be ensured.
