摘要
采用低压空气氧化法使废碱液中的 S2 -、SR-转变为 S2 O2 -3 、RSSR。该过程能否成功操作取决于温度、压力和空气与水的接触 ,尤其是空气与水的传质速度将会较大的影响硫化物的氧化去除速率和空气中氧气的利用率。
S 2- and SR in the spent caustic liquid was transformed into S 2O 2- 3 and RSSR by the air oxidation method with low pressure. Propitious operation of the process depended on temperature, pressure and the contact of air with wastewater, in practice, the speed of transporting mass of air and water considerably affected oxidation rate of the sulfide and availability of oxygen in air.
