摘要
对花垣河河水中8个监测断面(S1—S8)水样和堆积在河岸附近MnSO4废渣及其浸出液中Mn、Cd、Pb、Cu和Zn等5种重金属元素的总量进行了分析。结果表明,花垣河河水中Mn和Cd质量浓度超过《地表水环境质量标准》(GB3838-2002)Ⅴ类水体标准;MnSO4废渣浸出液中Cd超过《危险废物鉴别标准》(GB 5058.3-1996)规定值。将花垣河河水中Mn、Cd、Pb、Cu和Zn的含量与MnSO4废渣浸出液中相应的元素含量进行相关性分析,r=0.957(p<0.01),表明堆积在花垣河河岸附近MnSO4废渣是可能造成花垣河污染的主要来源。
The concentrations of metals Such as Mn, Cd, Pb, Cu, and Zn in the water sample collected from 8 sites （S1-S8） and the solution-ions in the manganese sulphate waste residue deposited along the Huayuan River were determined. The results showed that the levels of Mn and Cd were over the China environmental quality standards for surface water（ GB 3838 - 2002）. The levels of Mn, Cd, Cu and Zn in the leaching out liquid of manganese sulphate waste residue were over the China integrated wastewater discharge standard guideline （GB 5058.3 -1996）. A significant positive correlation of the average concentration of Mn, Cd, Pb, Cu, and Zn was obtained between the Huayuan River and the leaching out liquid of manganese sulphate waste residue （r = 0. 957, p 〈 0.01 ） by corresponding analysis . The Huayuan River pollution may be caused by the MnSO4 residue.
