摘要
详细阐述了废水可生化性的评价及测试方法。采集奎河断面污水,分析测定其化学耗氧量(CODCr)和生化需氧量(BOD5)。用BOD5/CODCr比值评价其污水的可生化性,并应用瓦勃氏呼吸仪测定生化呼吸线和相对耗氧速率与时间关系的曲线作进一步分析,结果表明:奎河污水是可生化的。这为城市污水处理厂选择污水处理方法提供理论依据。
The assessing principles and methods of biodegradability of the wastewater are introduced. Some wastewater samples are collected from the KuiHe River for Chemical Oxygen Demand and Biochemical Oxygen Demand test. The results are used for biodegradability study. The biochemical respiration curve and relative speed curve of oxygen consumption were determined by means of Warburg respiration apparatus, the results show that the wastewater of the KuiHe River is biodegradable, which will provide a theoretical basis for the wastewater treatment plant to choose treatment methods in the future.
