Purification treatment system for drinking water

Abstract

The invention provides a purification treatment system for drinking water, and relates to the field of water purification. The purification treatment system for the drinking water comprises a water inlet pipeline, a filtration treatment device, a main booster pump and a reverse osmosis membrane element; the first water outlet is connected with a water production pipeline, the other end of the water production pipeline is provided with a water storage tank, a flushing pipeline is connected in parallel between the water storage tank and the water inlet of the reverse osmosis membrane element, and the flushing pipeline is also provided with a circulating pump; a second water outlet is connected with a concentrated water pipeline, a circulating water connector and a drain valve are arranged on the concentrated water pipeline, a circulating pipeline is connected between the circulating water connector and the circulating pump, and a cleaning liquid container and a circulating control valve are arranged on the circulating pipeline; the purification treatment system has a physical flushing mode and a chemical cleaning mode, and in the physical flushing mode, the circulating pump and the drain valve are opened, and the circulating control valve is closed, so that the reverse osmosis membrane element is flushed and decontaminated; and in the chemical cleaning mode, the circulating pump and the circulating control valve are opened, and the drain valve is closed, so that the reverse osmosis membrane element is chemically cleaned.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a drinking water purification treatment system. Background technique [0002] With the gradual shortage of water resources, it has become a common practice in the water production industry to use water purification technology to remove salt, heavy metals and microorganisms in water to obtain safe drinking water. Among them, the reverse osmosis membrane technology is a process in which water molecules are reversely permeated from the high-concentration side to the low-concentration side under pressurized conditions. [0003] For example, the Chinese invention patent with the authorized announcement number CN105417753B and the authorized announcement date of 2019.08.06 discloses an energy-saving micro-concentrated water reverse osmosis device and its control method, and specifically discloses that the reverse osmosis device includes a waterway device and a circuit device...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above problems, the object of the present invention is to provide a drinking water purification treatment system to solve the problem that the reverse osmosis membrane element still has dirt deposited after the existing device is flushed with concentrated water, and the actual flushing and decontamination effect is poor.
