摘要
某金矿针对外排水中悬浮物含量过高问题,通过一系列试验研究,确定采用聚合氣化铝+聚丙烯酰胺组合药剂对悬浮颗粒进行絮凝沉降治理现场改造完成后,实现了外排水悬浮物含量低于20mg/L的治理目标,达到了国家环保政策要求。
In view of the problem of excessive suspended solids in the drainage of a gold mine,through a series of experiments,the flocculation and sedimentation treatment of suspended particles with polyaluminium chloride and polyacrylamide combined reagent was determined.After the site renovation is completed,the control target of suspended solids content less than 20 mg/L in external drainage has been achieved,it meets the requirements of the national environmental protection policy.
