摘要
采用混凝沉淀、铁碳微电解、芬顿氧化3种方法对高浓度制药废水进行降解实验研究,考察了单独方法和组合方法的实际降解效果,并寻找最佳处理效果的组合工艺。结果表明:高浓度抗生素废水,具降难解性,使用单一的物化处理法,去除效果均不佳,最大去除率为21.4%;采用两种组合处理工艺时,去除率最高提高13.9%;铁碳微电解反应结束后调节pH,COD的去除率更高。当原水COD为55 600 mg/L,经过混凝沉淀-铁碳微电解(调pH)-芬顿反应后,COD的去除率接近60%,该组合工艺具有去除率高,反应时间短的特点。
Experimental study on degradation of high concentration pharmaceutical wastewater by three methods, coagulation and sedimentation, iron-carbon micro electrolysis and Fenton oxidation, was carried out. The effect of the actual degradation alone and combination methods was studied in order to find the best combined treatment process. The results show： high concentration antibiotic wastewater with lower hardness, and the removal effect is poor by using the single physical treatment method, The maximum removal rate is 21.4%; the removal rate increases by 13.9% when using two kinds of combined treatment process; by adjusting pH after iron carbon reaction, COD removal rate is much higher. When the COD of raw water is 55 600 mg/L, after coagulation sedimentation - iron carbon micro electrolysis （adjusting pH） - Fenton reaction process, COD removal rate is close to 60%. The combined process has the characteristics of high removal rate, short reaction time.
