Description

Desalted water reverse osmosis concentrated water recovery device Technical Field The utility model relates to a concentrated water recovery device, in particular to a desalted water reverse osmosis concentrated water recovery device. Background This section provides merely background information related to the present disclosure and is not necessarily prior art. The reverse osmosis concentrated water recovery of desalted water refers to the technical process of recycling water resources or reducing pollutants by physical, chemical or membrane separation technology aiming at high-salinity wastewater (concentrated water) generated by a Reverse Osmosis (RO) system. The core logic is that concentrated water (TDS concentration is 3-5 times of inlet water) generated in the raw water desalination process is used as 'secondary resource', and the concentration, purification or recycling technology is adopted to reduce the discharge amount of wastewater and the salt pollution load. Most of the current desalted water reverse osmosis concentrated water recovery devices lack a classification filtering design, so that the treatment efficiency is low and the operation stability is insufficient. The traditional single-stage filtering structure (such as a single-layer filter element or a single membrane component) is difficult to realize the cooperative removal of multi-scale pollutants in high-salt wastewater, coarse-particle suspended matters easily penetrate through a filter layer and enter a subsequent precise component to cause membrane hole blocking or resin hardening, and micro-molecular organic matters and high-valence salt ions directly contact a high-precision membrane surface without pretreatment, so that concentration polarization and membrane pollution are aggravated, and a certain improvement space exists in the structure. It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.
