可生物降解性测定是污水生物处理的核心问题,它不仅可以为污水处理工艺流程的选择提供科学依据,还可以通过它找出影响现有污水生物处理设施正常运行的主要污染源;该技术还可以用于污水生物处理设施的日常管理中,以保证其正常运行。作者比较了测定污水可生物降解性的一些主要方法,分析了这些方法的适用性,并探讨了模型试验法和耗氧速率、脱氢酶活性测定法等在污水处理工艺开发及污水处理设施运行管理中应用的途径。

Determination of the biodegradability is the key issue during the biological wastewater treatment process.It can not only provide solid foundation to the selection of treatment process, but also can be used to trace the major pollution sources that exert adverse impacts on the biological wastewater treatment facilities.Furthermore, the technique can be used in the daily management to protect the wastewater treatment facilities against malfunctioning.In this paper, based on the comparison of existing biodegradability test techniques, approaches to the application of biodegradability test techniques in the development of the wastewater treatment process and in the routine management of wastewater treatment facilities are proposed.
