生物制剂深度处理技术处理含砷、锑的矿山废水

The Advanced Treatment Technology with Biologic Agent Treat the Mine Site Wastewater Containing Arsenic and Antimony

针对湖南省某矿区含砷、锑矿山废水的水质及水量特征,新建处理规模5000 m3/d的废水处理站一座,废水处理站选用生物制剂深度处理工艺对含砷、锑的矿山废水进行处理,处理后废水中砷、锑浓度均低于《锡、锑、汞工业污染物排放标准》(GB30770-2014)中污染物排放限值,可达标外排,也可回用于附近企业用作生产用水。

In view of the water quality and water quantity characteristics of mine wastewater containing arsenic and antimony in a mining area in Hunan Province, a new wastewater treatment station with a treatment scale of 5000 m3/d is built. The station chose the advanced treatment technology with biologic agent, the concentration of arsenic and antimony in the treated wastewater is lower than the discharge limit of the pollutants in the Emission Standards for Tin, Antimony and Mercury Industries(GB30770-2014), and can be discharged to the outside, or reused as production water for the nearby enterprises.
