磷灰石等改良剂对铜污染土壤的修复效果研究——对铜形态分布、土壤酶活性和微生物数量的影响
Amelioration Effect of Apatite and Other Amendments in Cu Contaminated Soil The Distribution of Cu Forms, Soil Enzyme Activity and Number of Microbial
摘要
Abstract
The effects of distribution of Cu forms, soil enzymatic activity and amount of microbial were studied in a field experiment after applied with apatite, lime, charcoal, pig manure and iron powder in Cu polluted soil. The results showed that percent of exchange state Cu decreased,percent of carbonate combined state Cu, Fe-Mn oxide combined state Cu and organic combined state Cu increased, but did not influence significantly residual state Cu. The activities of hydrogen peroxidase and acid phosphatase increased with apatite, lime, charcoal application, while ttrease activity changed little. The amount of bacteria and fungi increased after amendments applied, and positive correlation existed between the amount of microbial and soil pH, especially for fungi, the correlation coefficient reached 0.90 (p＜0.05). Soil pH is the main factor influenced distribution of Cu forms, soil enzymatic activity and amount of microbial. Apatite, lime and charcoal not only increased soil pH, decreased the activity of Cu in soil,but also enhanced the amount of microbial and soil enzyme activity, and then were considered as the most favorable remediation for Cu contaminated soil.关键词
