| 摘 要： | 采用小型工业试验,以聚合硫酸铝和非离子聚丙烯酰胺为絮凝剂,研究了MASS高效气浮对焦化废水的处理效能,考察了PAM加药位置、pH、体积回流比及絮凝剂浓度对絮凝气浮效率的影响,探讨了最大处理效率与进水水质的关系.结果表明,不加絮凝剂时气浮效果不理想,加入絮凝剂后气浮效率明显提高；PAM加药口应设在废水和溶气水混合之前,而不应设在混合之后；在焦化废水pH波动范围内气浮效率变化不大.当废水温度为(50±2)℃时,焦化废水经MASS高效气浮处理后除油率达35％～70％,COD去除率达5％～25％,油含量从30～140 mg·L-1降至20～40 mg· L-1,COD降至3 800 mg· L-1以下,该出水的油含量和COD均能满足生化进水的要求.综合来看,MASS高效气浮在焦化废水预处理中具有一定的应用潜力和可行性. |
