摘要
研究采用填充床电化学反应器,对低浓度含氰废水投加氯化钠进行间接氧化。试验表明:投加氯化钠可明显改善填充床反应器的工作特性,强化 CN^-的氧化过程,缩短废水在电解池里的停留时间。
Indirect oxidation of low concn.cyanide containing wastewater and reaction mechanism was investigated using packed bed electrode reactor.Results show addition of NaCl improves reactor performance obviously and enhance CN^- oxidation so that retention time of wastewater in elec- trolyzer can be shortened greatly.In addition,comparative experiments using different supporting electrolytes suggest CN^- is preceding to be adsorbed and discharge on graphite electrode under coexistance of CN^- and Cl^-.
