| Abstract: | Homogeneous catalytic oxidization technology is used for removing sulfide from spent alkali lye of ethylene cracking, and the various factors of influencing removal efficiency are investigated. It is shown that the conversion rate of S~(2-) can reach to above 96% when reaction temperature is at 20℃, reaction time is more than 90min, aeration amount is 75∶1, and the initial concentration of Mn~(2+) is (15mg/L). The great majority of S~(2-) is oxidized into S 2O 3~(2-) and only a little of it is oxidized into SO 4~(2-). BOD 5/CODcr of treated spent alkali lye increases from 0.21 to 0.50. |
