| Abstract: |
| Cyanide waste water was treated by using the O3 oxidation method from a certain gold mine of cyanide residue.Mainly investigated under the condition of same O3 concentration,oxidation reaction time,pH,catalyst,etc factors on cyanide removal effect and the optimum reaction conditions were determined.The results showed that under the conditions of without catalyst,the value was 7.0,reaction time was75min,the removal rate of maximum CN- was 96.3%,and the total CN- was 92.3%. |
