生活污水处理过程荧光光谱及紫外光谱特征分析
|
摘要
应用平行因子分析,并结合污水理化指标的相关性分析,对污水处理厂进出水以及各个处理单元中的污水的三维荧光光谱及紫外光谱特征进行了研究。对生活污水来源进行了解析并与同期工业污水进行对比。结果表明,污水处理厂中进出水以及各个处理单元的污水均含有3种主要的荧光组分,分别是UVA类腐殖质、UVC类腐殖质和类色氨酸。根据得分值可以得出处理后类色氨酸在污水的荧光组分中降低了94%,而类腐殖质趋于稳定。生活污水水质主要受类色氨酸影响,水质比工业废水较稳定。相关性分析表明,类色氨酸与传统指标具有较强的相关性,类腐殖质与UV254之间相关性较好。
Using PARAFAC and correlational analyses, the three-dimensional fluorescence spectrum and UV-vis characteristics of wastewater in the wastewater treatment plant(WWTP) and each unit were analyzed. The source of domestic wastewater was analyzed and compared with industrial wastewater during the same period. The results show that the wastewater in the WWTP and the wastewater in each treatment unit contain three main fluorescent components, namely UVA humus, UVC humus and tryptophan. According to the score value, it can be concluded that the treated tryptophan is reduced by 94% in the fluorescent component of the wastewater, and the humus-like substance tends to be stable. The quality of domestic wastewater is mainly affected by tryptophan, and the water quality is more stable than industrial wastewater. According to the correlation analysis, the tryptophan has a strong correlation with the traditional indicators, and the correlation between the humuslike substances and UV254 is good.
