It is preferablel to deal with cyanogen-contained wastewater by hydrogen peroxide processing.The optimum conditions are:The adding of hydrogen dioxide is 11mL,pH is 10,reaction time is 15min.The total cyanogen concentration is 201mg/L,the easy-released cyanogen concentration is 119.49mg/L,the total cyanogen concentration and easy-released cyanogen concentration will be 5.45mg/L and 4.96mg/L after treatment,respectively.the removing rate of total cyanide and easy-released cyanogen will be 97.29% and 95.85%,respectively.most iron and cyanide will be removed although it is not meet the discharge standard,the remained substance are mainly easy-removed cyanogen.The iron and cyanide concentration will meet the discharge standard.
