摘要
运用Tessier等提出的五步浸提法对经过好氧堆肥的污泥中的铬、镍、铜、锌、镉以及铅这六种重金属元素进行提取,测定含量,并对数据进行了分析,了解堆肥后的污泥中重金属的形态分布特征。结果表明,堆肥可以将大部分重金属的存在形态转变为稳定的残渣态,降低重金属的活性以及对环境的破坏性。
By using The five step of extraction that was proposed by Tessier et al, we have extracted the six heavy metal elements, chromium, nickel, copper, zinc, cadmium and lead, which belong to the aerobic composting sludge, determinates the content of them and analyzed the data, to understand the distribution features of the form of heavy metals in composting sludge. The results showed that the morphology of most heavy metals could be changed into stable residue state, and the activity of heavy metals and the damage to the environment were decreased.
