| 摘 要： | 分析了福州市洋里污水厂、祥坂污水厂和快安污水处理厂污泥中部分重金属总量和赋存形态,结果表明,污泥中的不同重金属含量存在着很大差异,其中快安污水厂的铅、铜、铬的含量都最高,分别为326.4 mg/kg、440.69 mg/kg、1 742.76 mg/kg,洋里污水厂的铅含量最高,达到401.9 mg/kg.同时铜、铅、锌、铬的可交换态、碳酸盐结合态与铁锰氧化物结合态分布总体较低,残余态和有机结合态分布较高.概述了污泥中重金属的去除方法,通过分析可知,重金属赋存形态对重金属的去除效率有很大影响,在选择去除方法时应该考虑重金属的赋存形态分布情况.

| Abstract: | The fraction of heavy metals in sewage sludge collected from Fuzhou Yangli wastewater treatment plant,Fuzhou Xiangban wastewater treatment plant and Fuzhou Kuai'an wastewater treatment plant is investigated.Results show that there is a great difference lies in different heavy metals from sewage sludge.The contents of Pb,Cu and Cr in sludge from Fuzhou Kuai'an wastewater treatment plant are the highest,which is about 326.4 mg/kg,440.69 mg/kg,1742.76 mg/kg respectively.At the same time,the exchangeable,carbon... |
