摘要 采用铁碳微电解-H2O2工艺对制药废水进行预处理。考察了静态实验条件下废水的初始pH、微电解填料投加量、水力停留时间(HRT)、H2O2浓度对反应效果的影响。实验结果表明,该工艺的最佳反应条件:pH=3.0、填料投加量=50g/L、应时间=180min、H2O2氧化剂浓度=0.6g/L。在此条件下,废水CODCr从初始的6977mg/L降到4331mg/L,去除率为37.92%,废水的BOD5/CODCr比由0.17提升至0.35,废水的可生化性得到有效改善。 The microelectrolysis-H2O2 process has been used for the pretreatment of pharmaceutical wastewater. The influences of initial pH value, iron-carbon catalyst dosage, reaction time, H2O2 concentration on the treatment effect were investigated. The best condition of the microelectrolysis-H2O2 process was as follows: 3.0 of the initial pH value, 50 g/L of the iron-carbon catalyst dosage, 180 min of reaction time and 0.6 g/L of H2O2 concentration. Under these conditions, the concentration of CODCr in the wastewater after the treatment decreased from 6977mg/L to 4331mg/L, the removal efficiency of CODCr was 37.92%, and the biochemical availability ha s been improved significantly with the ratio of BOD5/CODCr from 0.17 to 0.35.
