摘 要: 为促进污泥的应用和推广,在测定兰州市雁儿湾污水处理厂污泥基本性质的基础上,研究了堆肥化与粉煤灰对污泥中Zn,Cd,Pb 3种重金属有效态的影响。结果表明:堆肥化和粉煤灰可减少可交换态Zn,Cd和碳酸盐结合态Zn含量,而使碳酸盐态结合效态Cd,Pb含量增加;原状及改性粉煤灰对重金属形态的影响区别并不规律。
关 键 词: 固体污染防治工程;污泥;堆肥化;原状与改性粉煤灰;重金属形态

Abstract: In order to promote the application of the sewage sludge, based on determination of the fundamental nature of the sludge in Lanzhou Yaner Bay sewage treatment plant, the experiment researched the effect of composting and fly ash on the effective state of heavy metals Zn, Cd, Pb. The results showed that composting and fly ash can reduce the content of exchangeable Zn, Cd and carbonate-bound Zn, and increase the content of carbonate-bound Cd, Pb. The distinguish between impact of original and modified fly ash on the forms of heavy metals is not regular.
Key words: prevention and governance engineering of waste pollution;sewage sludge; composting; original and modified fly ash; forms of heavy metals
