摘要
滹沱河岗黄段湿地是石家庄市重要的水源地,其水体遭受到了不同程度的污染.采用相关加权污染状态指数法对研究区污染情况进行了分析,并就植物修复技术对滹沱河岗黄段湿地污染的治理进行了探讨.研究表明,滹沱河岗黄段水体的污染物主要有有机类、重金属类及氮类污染物.传统治理方法治理这些污染物比较困难,而且成本较高,而植物修复技术具有处理费用低、不造成二次污染等优点,并可有效降低污染物的毒害程度.
The Hutuohe River wetland is the main waterhead of Shijiazhuang; however, the water was polluted more or less. The article analyses current situation of heavy metals pollution by adoption of the ＂state-related pollution weighted index＂, and discusses phytoremediation technology in heavy metals pollution treatment. As Hg, Cr and Pb are main pollutants in the Hutuohe River wetland, the traditional remediation technologies are difficult and cost high in treating heavy metals pollution;whereas the phytoremediation technology has a lot of merits, such as low cost and no secondary pollution, and effective reduction of toxicity of heavy metals. The phytoremediation technology is significant in conserving rare wetland and water resources of Shijiazhuang.
