- Abstract:
- The possible effects of microbial oxidation and removal of AsⅢ in the presence of zero valent iron （ZVI）were studied. Quartz sand and that loaded with ZVI were filled into two up-flow fixed-bed reactors(R1 and R2) as support materials and microorganisms were inoculated and domesticated. The regularity of microbial oxidation of AsⅢ was studied with varied hydraulic retention time tHR.The results showed that we could get the highest capacity of icrobial oxidation at the bottom of the reactors. At higher tHR, almost 100% of AsⅢ was oxidized in R1 and R2. When tHR was changed to 0.67 h, R2 exhibited higher oxidation performance that R1. The presence of ZVI was more favorable for microbial oxidation of AsⅢ.
