Study on treatment of distilled ammonia waste water from coke plant with activated carbon-NaClO catalytic oxidation method

Catalytic oxidation method for the treatment of distilled ammonia waste waster from coke plant was investigated by using activated carbon as catalyst and NaClO as oxidant. The influences of main factors, such as NaClO, activated carbon, PH and reactionary time have been discussed. The results showed that under the conditions of 25℃, NaClO/COD0=1.5, carbon/ NaClO=0.6 and pH=3.0, the reaction completed within 120 minutes with 99.5% of phenol removal and 75.8% of COD removal when the distilled ammonia waste water from coke plant which containing phenol 510mg/L and COD08420mg/L was treated. 4 figs., 13refs.
