| 摘 要： | 分别对黑龙江地区4个城市污水处理厂污泥中重金属Cu、Zn、Cr、Ni不同化学形态的分布特征进行研究。结果表明,Cu和Cr主要以有机物结合的可氧化态和残留态形式存在,Zn主要以酸溶态和可还原态2种不稳定形式存在,Ni广泛分布于上述4种形态之中。污泥中重金属潜在移动性和生物可利用性顺序为：Zn〉Ni〉Cu〉Cr。

| Abstract: | The distribution of different chemical fractions of heavy metals Cu,Zn,Cr and Ni in the sludge from four wastewater treatment plants in Heilongjiang were studied.The results indicated that Cu and Cr mainly existed in oxidable and residual fractions,Zn mainly existed in acid soluble and reducible fractions which are unstable,Ni was widely distributed in all chemical fractions in the sludge.The order of the mobility and bioavailability of heavy metals were Zn>Ni>Cu>Cr. |
