摘要
采用湿式空气氧化技术对目前印染行业中排放的高浓度、难降解废水进行脱色处理,以酸性大红G水溶液为目标污染物,考察了温度、浓度、空气含量和pH这些因素对酸性大红G溶液脱色效率的影响。实验结果表明:当模拟废水浓度为250 mg/L,反应温度为200℃,反应时间90 min,反应釜内溶液填充度为75%,pH=7时,脱色效率可达到94%以上。
Wet air oxidation was used to study decolorization of the waste water which was high concentration and refractory degradationin in printing and dyeing industry. Take the simulate acid red G waste water as target pollutant, and the effects of concentration, temperature, air content and pH on decolorization efficiency were investigated. The results showed that the decolorization efficiency reaches about 94 % at 200℃ for 90 min when the initial concentration of Acid Red G simulate waste water was 250 mg·L^-1, decolorization effect was remarkable.
