Study on Zinc Desorption Regularity of Bottom Material in the Mining River

Bei Rongta1,Yu Jie2,Yang Yunhe1,Yao Yongsheng1(1.Department of Environment Science & Engineering,Southwest Forestry College,Kunming 650224,China;2.The First Vocational Secondary School,Kunming 650031,China)  
Through stirring the mixture of polluted bottom material and distilled water,the purpose is to imitate different current velocity state,to analyze the relations between different rotational speeds and the dissolved zinc content,to analyze different laying time quietly influencing zinc concentration in the suspension,to reveal regularity of zinc desorption in bottom material and zinc deposit in water quality.The results show that stirring activities accelerate zinc desorption in bottom material,and the different rotational speeds influence remarkably on the bottom material dissolved zinc content,that is,the faster the stir machines rotational speed is,the more the dissolved zinc content is.After the water samples are laid some time,the zinc content in the water is reducing gradually.However,the zinc content isn't outstanding difference from 30 minutes to 60 minutes in laying time quietly,and the same as from 120 minutes to 240 minutes.After the water samples are laid 30 minutes,the dissolved zinc content is not remarkable different among three rotational speeds.
