Abstract

The invention discloses a brine waste water processing reusing device and method. The structure of the device comprises a preprocessing system 1, an ultrafiltration processing system 2, a reverse osmosis processing system 3 and a negative pressure spray evaporation processing system 4. The device has the advantages that the device can be suitable for water draining, circulating water sewage draining, boiler sewage draining, demineralized water station resin regenerating water draining and the like of brine waste water primary treatment; organic pollutants and hardness in brine waste water are removed, and salinity is lowered; (3) the purposes of reusing and zero emission by efficient evaporating on thick water are achieved; (4) preprocessing, ultrafiltration and reverse osmosis are combined organically; (5) rolling type reverse osmosis and flat plate reverse osmosis are combined, and decrement is concentrated to the maximum degree; and (6) energy is saved, efficiency is high in low-temperature negative-pressure spray evaporation, and the purposes of reusing and zero emission are achieved.

Description

technical field

[0001] The invention relates to a saline waste water treatment and reuse device and a method thereof, and belongs to the technical field of industrial waste water treatment. Background technique

[0002] Domestic metallurgy, iron and steel, textile printing and dyeing, papermaking, salt chemical industry, petrochemical, coal chemical industry and other industries have developed rapidly. The circulating water sewage in the production process, the boiler sewage, the drainage of some production wastewater after treatment, the reverse osmosis concentrated water and ion in the desalination station Exchanging and regenerating acid-base neutralization and drainage constitute a large amount of saline waste water discharged, causing pollution to the surrounding water environment, wasting a lot of water resources, and restricting the development of enterprises. At present, under the environment of water resource shortage and national energy conservation and emission re...
