| 摘 要： | 利用瓦氏呼吸仪测定微生物耗氧量的方法 ,对硝基苯类污染物可生化性进行了研究。结果表明预处理、废水浓度以及污泥驯化对提高硝基苯类废水的生物降解性能有重要的意义。经铁碳内电解絮凝后的硝基苯类废水可生化性有明显提高 ,经驯化后的污泥能改善废水的生物降解性能。硝基苯可生化性的抑制浓度为 2 0 0～ 4 0 0mg L。实验证明利用瓦氏呼吸仪测定硝基苯类废水可生化性具有直接、快速的优点。

| Abstract: | The biodegradability of nitrobenzene was studied with Warburg respirometer measuring the oxygen demand by microbe. The result showed that pretreatment, concentration of waste water and acclimation of activated sludge were important to improving the biodegradability of waste water. After flocculation by iron carbon inner electrolysis, the biodegradability of waste water has been improved clearly. Acclimation of activated sludge is also helpful for improving the biodegradability of waste water. Inhibitory concentration of nitrobenzene is 200～400 mg/L. The experiment testified that the way to measure the biodegradability of nitrobenzene wastewater is effective, quick and clear with Warburg respirometer. |
