摘要/Abstract

摘要：

为了研究污水厂尾水对受纳水体的影响，采用XAD-8和阴阳离子交换树脂联用技术，对合肥市污水厂不同处理工艺出水以及朱砖井污水厂受纳河流上下游水样进行分离富集处理，获得了亲水性碱（HIB）、亲水性酸（HIA）、亲水性中性物质（HIN）、憎水性碱（HOB）、憎水性酸（HOA）和憎水性中性物质（HON）6种组分。采用DOMfluor、PARAFAC、PAC投影等数学分析方法，将前述5种树脂分离组分以及原水水样的荧光光谱进行解析，获得类蛋白质、类富里酸和类胡敏酸3种主成分。结合溶解有机碳分析结果，得到DOM总有机物中憎水性有机质约占75%，主要为类富里酸和类胡敏酸等憎水性腐殖质。结合傅里叶变换红外光谱分析结果，发现亲水性物质主要包含多糖、蛋白质和磷酸盐化合物等物质，憎水性物质HOA、HOB主要包含脂类和有机酸等。通过比较二十埠河上下游水样以及树脂分离后组分的主成分得分值，发现纳污河流污染较重，污水厂尾水对受纳水体水质影响较小。

Abstract:

In order to investigate the influence of effluents from the sewage treatment plants to the receiving waters, XAD-8, anion-exchange and cation-exchange resins were used to separate and enrich the effluents from different sewage treatment plants and the samples from the upstream and downstream of the Zhu Zhuan Jing sewage treatment plant's outlet, and six components were acquired such as the hydrophilic base (HIB), hydrophilic acid (HIA), hydrophilic neutral substance (HIN), hydrophobic base (HOB), hydrophobic acid (HOA) and hydrophobic neutral substance (HON). Mathematical methods such as DOMFluor, PARAFAC and PAC projection approach were used to decompose the EEM fluorescene spectra of the former five components and those of the original effluents, and three principal components, i.e. the protein-like, fulvic-like and humic-like substances, were acquired. According to the analysis result of Fourier Tranform Infrared (FTIR) spectroscopy, hydrophilic substances were mainly composed by polysaccharides, proteins, phosphate, etc. On the other hand, hydrophobic substances were mainly composed by lipids, organic acids and so on. In addition, the principal components scores were compared which were decomposed from the EEM fluorescence spectra of the upstream and downstream samples from the Er Shi Bu river. Results show that the receiving waters was seriously polluted and the effluents from sewage treatment plants had little effect on the receiving waterbody.
