Adjustable section type reverse osmosis membrane detection system

Abstract

The invention discloses an adjustable section type reverse osmosis membrane detection system. The system comprises a raw water tank, a water production tank, a concentrated water tank, an electric control device, and a first reverse osmosis membrane device, a second reverse osmosis membrane device, a third reverse osmosis membrane device and a fourth reverse osmosis membrane device which are connected in parallel. The system is provided with the four groups of reverse osmosis membrane devices, and four operation modes of any one-way or multi-way operation can be realized through valve adjustment; the raw water tank, the water production tank and the concentrated water tank are arranged, and switching between continuous self-circulation operation and non-self-circulation operation of the system can be achieved through valve adjustment.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment detection, in particular to an adjustable segment reverse osmosis membrane detection system. Background technique [0002] With the increasing demand for high-quality reclaimed water, RO (reverse osmosis) technology has gradually been widely used in the field of sewage regeneration to meet its desalination requirements. At the same time, reverse osmosis technology can effectively remove pollutants such as colloidal substances, pathogenic microorganisms, dissolved organic matter, and some ions. It has the advantages of a desalination rate of more than 90%, easy operation, stable water quality, and small footprint. Although at present, during the operation of the RO process, MF (microfiltration) or UF (ultrafiltration), grille, self-cleaning filter, security filter, etc. are used as pretreatment to ensure the quality of RO influent water, and a large amount of The medicament reduc...

AI Technical Summary

Problems solved by technology

Although at present, during the operation of the RO process, MF (microfiltration) or UF (ultrafiltration), grille, self-cleaning filter, security filter, etc. are used as pretreatment to ensure the quality of RO influent water, and a large amount of The medicament reduces, prevents or removes membrane fouling and ensures the efficient operation of the membrane. However, in the actual operation process, many dissolved substances, including organic and inorganic substances, can still pass through these pretreatment barriers and adsorb, accumulate or precipitate in the reverse osmosis process. Fouling of the membrane surface

The problem of membrane fouling is still one of the important problems faced by RO technology, which limits the operating efficiency of reverse osmosis process
