A new corrosion cell system which consists of iron chips, MnO 2 and activated carbon was employed in wastewater treatment. It was proved to be more effective in the treatment of reactive red dye X\|3B than the common method of iron chips. The COD removal rate was up to 82% and the chromaticity removal rate of reactive red dye X\|3B was over 98%.The best pH value for the most effective treatment is about 7 and it is a favourate condition for the practive application of the method. 催化铁-氧腐蚀电池 曝气 活性艳红X-3B 废水处理 10.14188/j.1671-8836.2000.04.013 O643.3 2000-04-01 2021-04-01 4
