  • 含氰尾矿适宜生长植物筛选试验研究……刘强,叶锦娟,吕春玲
  • 摘 要:西北某黄金生产企业尾矿库面临闭库,采用化学法处理工艺复杂、成本高,植物修复技术具有绿色、经济等优点,是处理闭库尾矿库的较佳选择。以该企业含氰尾矿作为研究对象,通过添加不同比例的城市生活污水处理厂产生的活性污泥和建设尾矿库时堆存的腐殖土作为植物生长的培养基质,选择7种不同植物在模拟西北气候条件下进行生长态势试验。结果表明,草木犀、燕麦、野茅、披碱草4种植物适合在含氰尾矿中生长。该研究为含氰尾矿的植物修复提供主体和参考。

    Experimentalstudy on selecting the plants fit to grow on cyanide tailings……LiuQiang,Ye Jinjuan,Lü Chunling

    AbstractThe tailings pond of a gold production enterprise innorthwest China is to be closed.It takes high cost and is complicated to treatthe tailings pond with chemical process.In contrast,the environmentallyfriendly and economic phytoremediation is better option to treat closedtailings pond.The paper takes the cyanide tailings from the gold productionenterprise as the research subject,chooses 7 different plants to conduct growthtest under simulated field climate conditions and with activated sludgeproduced by municipal sewage water treatment plant and stockpiled muck fromtailings pond construction added in different ratio to be used as the growthmatrix.The results show that 4 plants,namely the sweet clover,oat,goeringlemongrass herb and lyme grass are fit to grow on cyanide tailings.Thisexperiment provided the main body and reference for further phytoremediation ofcyanide tailings.
