利用污泥沉降比SV_(30)分析生化工艺运行状况

Analysis of Operation Conditions of Biochemical Treatment Processes by Sludge Settling Ratio(SV_(30))

污泥沉降比(SV30)是分析污水厂生化工艺中污泥性状乃至整个系统运行工况的重要指标。然而实践过程中,该指标仅被作为一个量化的数值参考而被忽视了其测定过程中所包含的大量信息。该文通过论述SV30测定过程中可观察到的各种现象,分析污水厂运行状况存在的问题和解决方案,提出了规范SV30测定过程的建议,为相关工程技术人员提供借鉴。

Sludge settling ratio （SV30） is an important index to analyze the characteristics of sewage sludge and the whole system running condition. But in the process of practice, SV30 was only used as a quantitative reference. Large amount of information contained in the measuring process was ignored actually. By discussing the various phenomena observed in the process of SV30 measurement, existing problems in the biochemical treatment process and its solutions were analyzed. Some suggestions were also put forward for the standardization of SV30 measurement, which can provide reference for the relevant engineering and technical personnel.
