混凝吸附处理选矿废水的研究

A Study of the Coagulative Precipitation Adsorption of Floatation Wastewater

针对南京栖霞山选矿厂废水的处理问题 ,研究了KAl(SO4 ) 2 ·12H2 O与聚丙烯酰胺 (PAM)联合混凝 ,然后活性炭吸附的方法 结果表明 :经该法处理后的废水不仅达到国家矿山废水排放标准 ,而且全部回用后选矿指标不受影响 此法不仅解决了生产中废水的回用问题 ,还节省药剂投放量 。

To dispose the wastewater of Nanjing Lead Zing Silver Mine,the coagulative precipitation activated carbon adsorption technology is employed.The experimental results show that not only the treated wastewater satisfies the national effluent disposal standards,but also the quality of the floatation does not change when the treated wastewater is fully reused.The technology validates the reuse of the treated wastewater and reduces the amount of the dosage of floatation collectors.It shows good economical benefits and promising prospects.
