摘　　要：介绍了铁屑过滤 +H2 O2 预处理难降解染料废水实验研究结果。采用铁屑过滤微电解法预处理难降解染料废水 ,当进水pH为 4,停留时间为 8min时 ,出水BOD5 COD较原水提高 0 .2— 0 .3;若在铁屑过滤进水中加入H2 O2 ( 30 % ) 8‰投加量 ,可使废水可生化性得到显著改善 ,有利于后续采用生化法处理。This paper has recommended the study result of pretreating hard biodegradable dye wastewater by iron fillings filter(IFF) + H 2O 2. When only using IFF, BOD 5/COD value of effluent increased by 0.2-0.3 than that of influent under pH 4 and HRT 8 min. When 30%H 2O 2 has been added to the influent at rate of 8‰, the biodegradation of this wastewater has been greatly improved so that biotreatment method will be efficiently used after IFF + H 2O 2.
