含正丁胺的废液处理工艺研究

Treatment of N-butylamine Effluent--A Technological Study

采用吹脱 冷凝 吸收及吹脱 吸收工艺分别处理正丁胺废水和混合含氮 (有机氮及无机氮 )废水。正丁胺废液经处理后 ,氮含量由 1 72 48g/L降至 35 40mg/L ,氮脱除率达 97 95 % ,COD值由 10 911mg/L降至2 85 7mg/L ,脱除率达 97 38% ;混合含氮废水经处理后 ,氮含量由 13 19g/L降至 95 2mg/L ,氮脱除率达99 2 8% ,COD值由 1910 5mg/L降至 2 6 9 8mg/L ,脱除率达 98 5 9%

N butylamine effluent (organic and inorganic nitrogen) are treated by using the blowing off condensing absorption process and the blowing off absorption process respectively. After n butylamine effluent is treated, its N content is reduced from 1 724?8 g/L to 35 40 mg/L, with a denitrification percent of 97 95%, and its COD value is reduced from 10?911 mg/L to 285 7 mg/L, with a removal percent of 97 38%. After N containing compound effluent is treated, its N content is reduced from 13 19 g/L to 95 2 mg/L, with a denitrification percent of 99 28%, and its COD value is reduced from 19105 mg/L to 269 8 mg/L, with a removal percent of 98 59%.
