气浮综合改进设施处理高浓度造纸废水

本文报道了气浮综合改进设施处理高浓度造纸废水的流程和改革，结果表明：改进后的气浮设施COD去除率由60％提高到75％，SS去除率由51％提高到71％，气浮出水河直接回用于造纸的主要过程，处理效果明显优于单纯的气浮处理。而且改进部分投资少，动力消耗少，是处理高浓度造纸废水的简便易行、值得推广的方法。

The Treatment of High Concentration Papermaking Waste Water With an Improved Air Flotation Method

This paper reports the technical process and effect of the treatment of high concentration pa permaking waste water with an improved air flotation method.Results show that COD elimina tion ratio is raised from 60 to 75 and the SS elimination ratio from 52 to 71. The treated water can be directly used in the papermaking process.These data indicate that the improved method is significatly better than the old one. Furthermre, it is a simple method needing not much invest ment nor much power, which is worth popularizing.
