摘　　要：以芦苇、水芹菜、香蒲为研究对象,采用水培法在不同Cr2+浓度条件下,研究了水生植物对含铬污水的吸收和富集作用。结果表明:芦苇对Cr2+的去除率高于水芹菜、香蒲;植物根系对Cr2+的吸收富集作用优于植物茎叶,且芦苇对Cr2+具有较好的富集效果。With reed, water celery, cattail as the research object, using the method of water culture at different Cr^2＋ concentrations,the absorption and accumulation of Cr^2＋ from sewage were studied. The results showed that.the Cr^2＋removal rate of reed was higher than that of water celery and cattail,Cr^2＋ concentration in roots was significantly higher than that in stems and leaves,and reed had a better enrichment effect.
