摘　　要：黑龙江鹿鸣矿业尾矿库泄漏事件是我国近20年尾矿泄漏量最大、处理难度最高的突发水污染事件。在事件现场应急处置工作中,经过小试实验,探究了4种不同药剂组合工艺(PAC-PAM、PAFC-PAM、PAMPAC、PAM-PAFC)的去浊除钼效果,最终选用投加“PAM 10 mg·L^(−1)+PAFC 300 mg·L^(−1)”的组合工艺处理受污染河水。依据应急处置指挥部确立的总体策略,在污染较严重的依吉密河实施了“控制工程”,采用5级投药的方式在呼兰河实施了“清洁工程”。经过20 d的应急处置,受污染河水钼含量全线达标,成功实现了设定的应急处置目标。Leakage of tailing pond of the Luming mine in Heilongjiang Province is the largest and most difficult emergency water pollution incident in China in the past two decades.After the incident,the emergency team immediately went to the incident site to carry out emergency treatment work.After a lab-scale experiment,the turbidity and molybdenum removal effects were investigated via four different chemical combination processes(PAC-PAM,PAFC-PAM,PAM-PAC,PAM-PAFC),and finally chose 10 mg·L^(−1) PAM and 300 mg·L^(−1) PAFC combination process to treat the contaminated river water.According to the overall strategy of opening up“two battlefields”and implementing“two major projects”established by the headquarters,“control engineering”was implemented in the more polluted Yijimi River and“cleaning process”was implemented in Hulan River by means of five-level dosing.After 20 days of work,the molybdenum content of the polluted river water reached the standard and the predefined emergency target was successfully achieved.
