| Abstract: | This paper deals with DSD acid oxidation wastewater treatment with extraction method .An extraction system of wastewater/H 2SO 4/TOA-kerosene has been established and the parameters such as extraction phase ratio,water phase acidity,dilution ratio,extraction temperature,reaction time,agitation intensity,alkali concentration in reextraction and reextraction temperature have been optimized.The experimental results showed that the removal rates of COD and colourity of the wastewater could reached 94.3% and 99.6% respectively after extraction. |
