摘要
对砂滤-活性炭吸附工艺深度处理制药厂废水进行了研究。砂滤保证活性炭吸附柱的进水要求,活性炭吸附采用三级吸附。实验表明,采用此工艺处理该废水完全达到处理要求,即进水化学需氧量(CODCr)质量浓度控制在400mg/L以下,通量控制在25L/h,进水倍数在1000倍以内,出水CODCr可控制在100mg/L以下。采用两种方法对达到吸附饱和的活性炭进行了再生,结果显示酸碱再生法的处理效果明显优于溶剂再生法。
The sand filtration-activated carbon adsorption technique for pharmaceutical wastewater treatment was studied. Sand filtration ensured the water requirements of activated carbon adsorption column. Three-stage activated carbon adsorption was used. The experiment revealed that it can meet the processing requirements by using this technique, controlling the influent CODCr concentration not more than 400mg/L, the flux of 25L/h, water feed less than the times of 1000, and the effluent CODCr can be controlled within 100mg/L. Besides, two methods were used to regenerate the adsorption-saturated activated carbon. The results indicated that the treatment effect of acid-base regeneration is obviously superior to solvent regeneration method.
