Heavy Metal Leaching Of Lead And Zinc Tailings Library Release Mechanism And Its Leachate Treatment Design

The environment pollution and ecological destruction caused by leachate from lead-zinc tailings reservior is a global event which has attracted more and more attention and has become an important field for environmental science research.Heavy metal element with leachate from lead-zinc tailings enter groundwater or surfacewater is very difficult for eliminating,as well as it will threat enviormental quality and health of human greatly,also aggravate crisis of water resource. study on the mechanism of leaching and releasing of heavy metal from lead-zinc tailings can supply science support and theory gist for controlling pollution caused by heavy metal of leachate.establishing forecast model about concentration of heavy metal of leachate from lead-zinc tailings resevior based on simulation experiment in laboratory is the precondition of program design and process choice for leachate treatment.In this paper,DaYi Jinxing concentration plant is used as the study objiect,after domestic and overseas studies about enviormental effect from leaching of heavy metal in lead-zinc tailings were summarized,such test as the lixiviate experiment, static leaching experiment and dynamic leaching experiment were adopted in laboratory .study on mechanism of heavy metal leaching in lead-zinc tailings can tell us the concentation predict model of leachate from lead-zinc tailings resevior.These results can be obtained in this research,lead-zinc tailings belong to dangerous waste solid,and the external factor such as temperature,can affect leaching of heavy metal.The above simulation experiment in laboratory and design program of leachate treatment supply a method for dealing with the pollution from...
