【摘要】 采用烧杯试验法对羊绒制品染整废水进行海绵铁内电解法去除色度及化学需氧量(COD)的试验研究。试验结果表明,海绵铁投加量在500 g/L、pH 5～6、反应时间为60 min,在一定的搅拌强度下辅以混凝、氯氧化综合作用,色度的去除率达到90%以上、COD的去除率达到95%以上,废水出水能达到国家标准。更多还原

【Abstract】 The beaker test was applied to evetuate the effects of sponge iron internal electrolysis for removing to remove the color and COD of dyeing and finishing wastewater.The results were as follows,the dosage of sponge iron at 500 g/L,pH 5～6,60 min of reaction time under certain degree of mixing strength,combining with coagulation;chlorine could remove more than 90% of color,95% COD.更多还原
