Treatment of high-salt wastewater How to treat the salt contained in the wastewater
The concentrated solution produced by the treatment of saliferous wastewater by membrane concentration or thermal concentration technology is called concentrated brine. The treatment of concentrated brine is an important link to truly realize zero discharge of wastewater. The ways to achieve zero discharge of concentrated brine are mainly divided into two categories, one is regional zero discharge, and the other is zero discharge in the plant.
Regional zero-discharge mainly refers to other enterprises or places that can absorb concentrated brine in the surrounding area of the project and realize the cascade utilization of water resources through comprehensive utilization. Other enterprises or places that can absorb concentrated brine include ironmaking blast furnace, coal washing plant and other enterprises with low water quality requirements, as well as boiler slag washing, coal yard, slag yard spraying, etc.
