摘要:
鹿鸣矿业尾矿库泄漏事件导致大量含钼尾矿砂水泄漏入河，造成下游河流严重污染并威胁饮用水水源地安全，如何科学有效地开展环境应急处置是现场应急工作难点。系统阐述了该次事件的应急处置决策、应急方案制定和工程实施成效，主要包括应急目标制定、水质监测分析、应急处置思路及工程措施等内容。在现场环境应急过程中，通过开展封堵泄漏点、筑坝拦截、混凝沉淀等措施，实施污染控制、削峰清洁两大工程，实现了“不让超标污水进入松花江”的应急目标。最后总结了该次事件应急处置的成功经验，提出了尾矿库环境风险防控与处置的建议。
Abstract:Luming mining tailings pond leakage incident resulted in a large amount of molybdenum-containing tailings water leaking into the river, causing serious pollution of the downstream river and threatening the safety of drinking water source. Scientifically and effectively carrying out environmental emergency disposal was a difficulty of the on-site emergency response work. The emergency disposal decision-making, the emergency plan formulation and the project implementation results were systematically expounded, mainly including emergency goal formulation, water quality monitoring and analysis, emergency disposal ideas and engineering measures, etc. In the process of on-site environmental emergency response, through the implementation of measures such as plugging leakage points, dam blocking and interception, coagulation and precipitation, two major projects for pollution control and for pollutant concentration peak reduction and water purification were implemented to achieve the emergency goal of "not to allow standard-limits-exceeding water entering Songhua River". The successful experiences of emergency disposal of this accident was summarized, and suggestions for the prevention, control and disposal of environmental risks of tailings pond were put forward, so as to provide reference for scientific prevention of environmental risks of tailings pond and proper response to such sudden environmental emergencies.
