摘　　要：复合高铁酸盐用于处理经生化处理后不能达标的焦化废水的深度脱色处理,废水色度可从80降至25以下。复合高铁酸盐脱色的适宜条件为:复合高铁酸盐浓度1.7mg/L,溶液pH值3.5～7.0,反应时间30min,反应温度室温。The stability of the compound ferrate, the influences of the concentration of the compound ferrate, pH value, reaction time and temperature were studied in the decolouration of the cocking wastewa-ter. The experiment results indicated that the additive A can obviously improve the stability of the solution of the fresh compound ferrate. The compound ferrate exhibited excellent decolorant effect in the decolonra-tion of the cocking wastewater. The colority of the treated cocking wastewater was lower than GB standard of discharge water.
