偏重亚硫酸钠-空气法处理酸性含氰污水的应用研究

Applied study on treating cyanidebearing waste water by Na2S2O5AIR method

偏重亚硫酸钠（Ｎａ２Ｓ２Ｏ５）－空气（ＡＩＲ）法是ＳＯ２－ＡＩＲ法中采用Ｎａ２Ｓ２Ｏ５代替ＳＯ２的一种方法。通过对该法进行的小型试验和工业试验研究，其结果表明：处理低质量浓度含氰污水，氰化物可以达到国家《污水综合排放标准》，而且克服了ＳＯ２－ＡＩＲ法因ＳＯ２来源紧张和运输困难上的缺点。

To replace SO2 in the SO2AIR method with Na2S2O5 forms Na2S2O5AIR method.It shows from smallscale test and commercialscale trail that the cyanidebearing waste water at low density can be welltreated to meet the statespecified synthetic drainage standards of waste water and overcome the short supply and difficult fransportation of SO2,if the SO2AIR method is not given up.
