阴极氧还原产电生物可渗透反应栅的研究Ⅱ．酸蚀处理对不锈钢丝电极性能的影响
Study on cathodic oxygen reduction electricigenic permeable reactive barrier：Ⅱ. Effects of acid pre-treatment on electrode performance of stainless steel fibers
摘要
Abstract
The current of stainless steel cathodic oxygen reduction electricigenic permeable reactive barrier （CORE-PRB） is limited though stainless steel fiber has many advantages to act as the electrodes. It was tried to pre-treat the stainless steel fiber with hydrochloride acid to improve its electrode performance in CORE-PRB. Four types of the electrode pairs were tested. Acid pre-treatment improved much more of the anode performance than of the cathode performance. Acid-pretreatment made the surface of the fibers coarser so that the specific surface area of the fibers and the attachment of the microbes were improved. The COD removals of the different electrode pairs were quite positively correlated with the coulomb efficiency though the later was less than 10%.关键词
