摘要
采用模糊综合分析法对污水厂全年运行的稳定性进行评价,同时利用平行因子法提取三维荧光光谱中的类蛋白质荧光物质,并对每月的荧光强度得分变化进行对比分析,以更好地把握污水厂处理效果的总体动态。结果表明,通过模糊综合分析、常规化学指标分析以及荧光强度得分分析的结果基本一致,均显示该污水厂6、7、8月份的处理效果不佳,全年运行稳定性较差。该研究为如何实现直观、快速、准确、系统地评价污水厂运行的稳定性提供了可行的方案。
The operational stability of municipal sewage treatment plants （MSTP） of the whole year was evaluated using the fuzzy comprehensive analysis method . To better understand the overall dynamic effect of the sewage treatment plants ,the protein‐like substances were characterized using three‐dimensional excitation‐emission matrix fluorescence spectroscopy combined with parallel factor analysis （PARAFAC） ,and its fluorescence intensity scores was acquired and evaluated .The results show that the analysis of fuzzy comprehensive evaluation is consistent with the general chemical index and fluorescence intensity .and the treatment effect of the MSTP in June ,July and August is poor , w hich lead to unstable operation stability .T his study provides an intuitive , rapid , accurate and systematic method to evaluate the operational stability of sewage treatment plant .
