摘　　要：本文研究了废暖废渣作为催化剂的Fenton法在处理制药废水方面的应用。通过单因素法讨论了催化剂添加量、 H_(2)O_(2)添加量、pH和反应时间对环丙沙星废水处理效果的影响,并优化了非均相Fenton法的操作条件,研究结果表明,暖贴废渣为催化剂的Fenton法能有效去除废水中的环丙沙星,去除效率在70%左右;最适操作条件为:废暖废渣添加量2.5 g/L、H_(2)O_(2)添加量0.6 mL/L、pH=5、反应时间120 min;暖贴废渣处理环丙沙星的作用机理,除了氧化作用外,吸附作用可能是另一个重要作用机理。The application of the Fenton method with waste heating pieces residue as catalyst in the treatment of pharmaceutical wastewater was studied. Using single-factor method, the influence of catalyst dosage, H_(2)O_(2) dosage, pH and reaction time on the effectiveness of ciprofloxacin wastewater treatment was discussed and the operating conditions of the heterogeneous Fenton reaction system were optimized. Results showed that the Fenton method with waste heating pieces residue as catalyst can effectively remove ciprofloxacin in wastewater with a removal efficiency about 70%. The optimal operating conditions were as follows: waste heating pieces residue dosage was 2.5 g/L, H_(2)O_(2) dosage was 0.6 mL/L, pH was 5 and reaction time was 120 min. In addition to oxidation, adsorption might be another important mechanism of waste heating pieces residue treatment of ciprofloxacin wastewater.
