摘要
研究了染料废水中苯胺类污染物的处理工艺。催化湿式氧化预处理后的水经A/O工艺生化处理,可以达到污水综合排放标准GB8978-1996一级。催化湿式氧化的预处理条件的最佳工艺条件:温度170℃,催化剂投加量1000 mg/L,空气压力5.0 MPa,反应时间2小时,苯胺类去除率99%。
A treatment process for dyes wastewater containing aniline pollutants was studied.The wastewater pre-treated by catalytic wet oxidation and treated by A/O biological process could meet National Integrated Wastewater Discharge Standard(GB8978-1996) Grade I.The optimum conditions of catalytic wet oxidation pre-treatment were temperature 170 ℃,catalyst dosage 1 000 mg/L,air pressure 5.0 MPa and reaction time 2 hours.The removal efficiency of anilines was 99%.
