摘要
本文采用原子吸收分光光度计法测定了蚯蚓饵料污泥中重金属Cd、Pb、Zn、Cu及Cr含量。结果表明,蚯蚓饵料污泥中重金属Cd超过CJ221-2005《城市污水处理厂污泥检验方法城市污泥》标准限值,其余重金属均在限值内,且远小于限值。
The content of heavy metals Cd,Pb,Zn,Cu and Cr in sputum bait sludge was determined by atomic absorption spectrophotometer.The results showed that the heavy metal Cd in the bait feed sludge exceeded the standard limit of CJ221-2005"Urban Sewage Treatment Plant Sludge Inspection Method Municipal Sludge",and the remaining heavy metals were within the limits and far less than the limit.
