Baotou Steel Rare Earth will carry out high-salt wastewater zero emission test

In order to achieve national emission standards for pollutants rare, with good dam sewage treatment, recently, the expert discussion, decided to launch the Baotou Rare Earth High-salt zero discharge of wastewater treatment and recycling is in a pilot project.

End of this year, promised to stop the Baotou Steel Rare-Earth smelting wastewater discharge tailings deadline is approaching, before this, measures must be taken on the Baotou Rare Earth saponification wastewater, resulting separation of rare earth smelting waste water, waste, exhaust gas recycling, to achieve zero discharge of wastewater. Environmental and Chemical Engineering, Yanshan University College Professor Han Shumin smelter on the Baotou Rare Earth High-salt zero discharge of wastewater treatment and utilization projects in the test loop technical solutions are considered, the process salt conversion rate, sodium chloride reuse do saponifier; bicarbonate and low cost of raw materials; process is simple, stable and reliable; whole process carried out in a sealed container, no secondary pollution, reliable technology is feasible. Baotou Steel Rare Earth management and technical staff after careful argumentation and discussion, consensus, pilot testing will soon begin.
