腐植酸、EDTA、Cr（Ⅵ）调控猪粪尿废水异化Fe（Ⅲ）还原偶联VFAs的转化能力比较
A comparative study on ability of humic acids, EDTA and Cr(Ⅵ)to regulate dissimilatory Fe(Ⅲ)-mediated transformation of VFAs in swine wastewater
摘要
Abstract
Research has showed that environmental factors influence dissimilatory Fe(Ⅲ)-mediated transformation of VFAs in water. Here we examined the effects of humic acids, EDTA and Cr(Ⅵ)at different concentrations on the ability of dissimilatory Fe(Ⅲ)to regulate the degra-dation of VFAs in swine wastewater at constant temperatures. The reduction of Fe(Ⅲ)oxides was promoted by addition of humic acid to swine wastewater, and the rate of VFAs degradation was accelerated by increasing amount of humic acid. However, trisodium EDTA and Cr(Ⅵ)inhibited the reduction of Fe(Ⅲ)and slowed down the degradation of VFAs. Although these three factors had different mecha-nisms and processes influencing Fe(Ⅲ)reduction, the final reduction of Fe(Ⅲ)and the balance points of VFAs remained same.关键词
