铁和硫的形态转化与水体黑臭的关系

The relationship between the form transformation of iron and sulfur and the black-odor water body

介绍了黑臭水体概念及形成原因,分析了自然水体中铁与硫的赋存形态、转化过程和影响因素,阐明铁与硫的形态转化与水体黑臭的关系:以有机物为主的耗氧物质破坏水体中铁与硫循环因而造成Fe2+与H2S大量累积,出现水体黑臭现象。

This paper briefly introduces the concept and the formation of black-odor water body,and analyses the speciation of iron and sulfur,the transformation processes and influencing factors. Additionally,the relationship is reviewed regarding the form transformation of iron and sulfur and the black-odor water body i.e. The oxygen-consuming organic matters destroy the natural cycle of iron and sulfur and thus the accumulation of Fe2 + and H2S,resulting in malodorousness.
