Deck-mounted instant filtration water purifying system and water purifying method thereof

Abstract

The invention discloses a deck-mounted instant filtration water purifying system and a water purifying method thereof. The deck-mounted instant filtration water purifying system comprises a water tankand a membrane system, wherein a boosting pump is arranged at the water inlet end of the membrane system; the water tank is provided with a first waterway and a second waterway connected in parallel;the first waterway and the second waterway are connected in parallel and then are connected with the boosting pump; the first waterway is provided with a first one-way valve and a pretreatment filterelement; the second waterway is provided with a return flow solenoid valve; the membrane system is provided with a water producing waterway and a reflux waterway; the reflux waterway is connected with the water tank; the water producing waterway is provided with a water producing solenoid valve and a water producing circuit; the water producing circuit is provided with a second one-way valve andis connected with the first waterway between the first one-way valve and the pretreatment filter element. The deck-mounted instant filtration water purifying system and the water purifying method thereof disclosed by the invention can improve the water quality of first-strand produced water of secondary produced water after shutdown of a deck-mounted instant filtration high-flow water purifier, and has the characteristic of convenience in use.

Description

Technical field [0001] The present invention relates to the technical field of water quality purification, in particular to an on-stage water purification system and a water purification method thereof. Background technique [0002] Nowadays, whether it is industrial production, such as the production of products in many industries such as biology, medicine, petroleum, chemical, semiconductor, etc., which have strict requirements on water, or scientific research institutes, laboratories, and even our daily life, the water quality The requirements are getting higher and higher. Therefore, we need to treat the water to remove various toxic and harmful substances and impurities, so as to meet the requirements of our application. With the development of urbanization in our country, water purifiers have gradually become popular. Among the water purifiers, filtration technologies such as reverse osmosis, nanofiltration or ultrafiltration have gradually become the mainstream, but the p...

Problems solved by technology

With the development of urbanization in our country, water purifiers are becoming more and more popular. In water purifiers, filtration technologies based on reverse osmosis, nanofiltration or ultrafiltration have gradually become the mainstream, but the table-mounted filter-type large-flow water purification The water purifier has not yet become the mainstream, the main reason is that the table-mounted water purifier, especially the filter-type high-flow membrane system based on reverse osmosis or nanofiltration membrane, has serious shutdown salt penetration phenomenon, resulting in considerable Too much water has TDS exceeding the standard
