摘要
以Ca/Mg/Al絮凝剂处理烟草废水,考察絮凝时间、絮凝剂投加量及溶液pH值对COD及色度去除的影响。当絮凝时间为10min,絮凝剂投加量为40g/L,溶液pH为8时,COD由原样的2 000mg/L下降到816mg/L,且色度由200倍下降到10倍,COD去除率和脱色率分别达59.2%和95%。
The impact of COD and color removal involving time,coagulant dosage and pH were considered when Ca/Mg/Al coagulant was applied to treat tobacco wastewater.The optimization conditions were ob-tained from single factor experiment as follows：reaction time 10 min,coagulant dosage 40 g/L and pH 8. Finally,under the optimal conditions,the 59.2% of COD removal and 95% of color removal were reached with COD decreased from 2000 mg/L to 81 6 mg/L and color from 200 times to 10 times.
