摘要:
研究了零价铁(ZVI)的存在对生物氧化及去除水中三价砷(As)的可能影响。将石英砂及负载有零价铁的石英砂分别作为载体材料填充到两个平行的上流式固定床反应器(R1和R2)中并接种驯化微生物。在整个试验期间,通过改变不同水力停留时间tHR来研究微生物氧化As的规律。结果表明,上流式固定床反应器的底层生物氧化As的能力最高;当tHR较高时,R1和R2对As的氧化效率均能达到100%;在tHR缩短至40min时,R2比R1氧化效率高。ZVI的存在更有利于生物氧化As
Abstract:
The possible effects of microbial oxidation and removal of  As 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  As 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 As 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 As.
