针对福州市大学城地区供水设施及工艺落后、供水水质不稳定、供水量无法满足人口急速增长和用水量急剧增加的用水需求等问题,对福州大学城水厂进行改建,给出了设计方案与参数,并分析其建设特点及去除污染物效能。福州大学城水厂采用双水源,主体工艺为折板反应/平流沉淀池/V型滤池/二氧化氯消毒,并将清水池叠建于折板絮凝平流沉淀池和滤池下部。运行结果表明,该水厂出水水质满足《生活饮用水卫生标准》(GB 5749—2006)。经分析,有机物主要在混凝阶段去除,对TOC、UV254和CODMn的总去除率分别为54.24%、68.07%和48.45%,出水TOC与UV254之间具有较大相关性。三维荧光光谱分析得出,对溶解性有机物中的色氨酸、紫外区富里酸和可见区富里酸的去除率分别为49.18%、59.41%和59.46%。
In view of the problems such as the backward water supply facilities and technology, the unstable water quality in the university town of Fuzhou, the inability of the water supply to satisfy the rapid population growth and the sharp increase of water consumption, Fuzhou University City Waterworks is rebuilt, and the design scheme and Parameters, and analysis of its construction and removal of pollutants performance. Fuzhou University City Water Works using dual water sources, the main process for the folding reaction / advection settling tank / V-type filter / chlorine dioxide disinfection, and the water pool stack built in the flap flocculation sedimentation tank and the lower part of the filter. Operation results show that the water quality of the water plant to meet the “drinking water health standards” (GB 5749-2006). After analysis, the organic matter was mainly removed in the coagulation stage. The total removal rates of TOC, UV254 and CODMn were 54.24%, 68.07% and 48.45% respectively. There was a significant correlation between effluent TOC and UV254. Three-dimensional fluorescence spectroscopy analysis showed that the removal rates of tryptophan, fulvic acid in the ultraviolet region and fulvic acid in the visible region were 49.18%, 59.41% and 59.46% respectively.
