Abstract

The invention discloses a water purification system. The water purification system includes a membrane filter element having a raw water port communicating with a raw water pipe, a pure water port communicating with a pure water pipe and a waste water port communicating with a waste water pipe, a water inlet valve mounted on the raw water pipe, a booster pump mounted on the raw water pipe betweenthe water inlet valve and the membrane filter element, a water tanking switch mounted on the pure water pipe, a pure water return pipe with a water inlet end communicating with the pure water pipe anda water outlet end communicating with the raw water pipe, a pure water return valve mounted on the pure water return pipe, a water storage device including a first water storage cavity communicatingwith pure water and a second water storage cavity communicating with raw water which are independent, and a waste water reuse pipe with a water inlet end communicating with the waste water pipe and the other end connected to the raw water pipe, wherein the wastewater reuse pipe is used for returning waste water of the membrane filter element to the raw water pipe or the water storage device for reuse. Through the arrangement, the water quality of a first cup of pure water produced by the water purification system every time the system is started can be reduced and the waste water can be fullyand reasonably used.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification system. Background technique [0002] The problem of drinking water is a matter of great concern to the public. It is an indisputable fact that there are many substances that are not conducive to health in the water. This is also the main reason why people's awareness of healthy drinking water has been strengthened, and it is also the root of the hot water purification equipment market. [0003] The existing water purification equipment mainly relies on the membrane filter element to filter the raw water. However, when the water purification equipment is in the standby state, there will be raw water, waste water and pure water in the membrane filter element at the same time. In front of the membrane, the pure water is behind the membrane of the membrane filter element, and the total dissolved solids (TDS) values ​​of raw water and wastewater are mu...
