| Abstract: | The combined process of biological oxidation and ozonation is used to treat coking wastewater,and the influence of hydraulic retention time,ozone dosage,pH and oxidation time are investigated.The result shows that this treatment can efficiently reduce the pollutant organic concentration in the wastewater,and when the COD concentration of influent ranges from 987 to 1123mg/L,the COD concentration of effluent is below 150mg/L stably after the treatment,which meets the secondary discharge standard. |
