Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and particularly to a reverse osmosis concentrated water recovery device. Background Art

[0002] Reverse osmosis concentrated water is wastewater containing high-concentration pollutants generated during the treatment process of reverse osmosis (RO) technology. It is a by-product generated when the reverse osmosis system separates the solvent and solute under high pressure. Reverse osmosis allows water molecules to pass through the semi-permeable membrane under the drive of pressure, while the solute is intercepted, and the part that is not permeated is the concentrated water. The dissolved solids (such as inorganic salts sodium and chlorine), organic substances, and impurities in the raw water are concentrated on the high-pressure side of the membrane. Therefore, the salt content and pollutant content of the concentrated water increase significantly.

[0003] According to the specific composition and concentration of the concentrated water, it can be considered to be directly used in certain specific industrial processes, such as cleaning, cooling, etc. If the salt content or other solute concentration of the concentrated water is too high and not suitable for direct reuse, further treatment technologies, such as distillation, membrane separation, etc., can be considered to reduce the salt content and other solute concentrations in the concentrated water. The salts and other solutes in the concentrated water sometimes have certain economic value, and through appropriate extraction and utilization, the concentrated water can be transformed into valuable resources. In view of the above characteristics of the concentrated water, mechanical filtration, softening and other measures need to be carried out before reuse to make the pretreated concentrated water basically meet the water quality standard of the raw water and enter the raw water tank for repeated utilization. In the prior art, the recovery and pretreatment of the concentrated water are carried out separately, and the process efficiency is relatively low; in addition, the filtration devices used for the pretreatment of the concentrated water are generally of single-channel structure, so they must be cleaned regularly and it is difficult to achieve continuous operation. Summary of the Invention
