摘要:
生产废水回用是给水厂节能减排的重要方式之一。以赣江水源给水厂为研究对象，对雨季污染程度相对较高的赣江原水、给水厂沿程水和回流的生产废水进行分析，测算了氨氮（NH4+-N）、总氮（TN）、溶解性有机碳（DOC）等指标的污染负荷，利用三维荧光-区域积分法（FRI）分析了水样中溶解性有机物的分布特征，考察了生产废水回流对典型高致毒性卤乙酰胺类（HAMs）生成势的影响及其与水质指标和各荧光区域积分体积之间的相关性。结果表明，雨季回流虽然会增加工艺的有机物和无机氮污染负荷，但强化混凝作用会使出厂水的总体荧光强度较无回流工艺低约1.7%，还会影响沿程出水中HAMs生成势的变化趋势。Pearson相关性分析显示，各处理单元出水中芳香蛋白酪氨酸类物质、硝酸盐氮浓度和UV254与三氯乙酰胺（TCAM）和总生成势之间呈现显著相关，且各荧光区域积分能有效预测二氯乙酰胺（DCAM）和TCAM的生成势。总体而言，在雨季生产废水可进行间接回流，对出厂水水质影响较小。
Abstract:
Recycling production wastewater is an important method for water treatment plants to achieve energy conservation and emission reduction. Taking the water treatment plant using Ganjiang River water source as the study object, an analysis was conducted on the raw water from Ganjiang River, which has relatively high pollution levels during the rainy season, the water along the treatment process, and the recycled production wastewater. The pollution loads of indicators such as ammonia nitrogen (NH4+-N), total nitrogen (TN), and dissolved organic carbon (DOC) were calculated. The three-dimensional fluorescence-region integral method (FRI) was used to analyze the distribution characteristics of dissolved organic matter in the water samples. The impact of production wastewater recycling on the formation potential of highly toxic haloacetamides (HAMs) and its correlation with water quality indicators and the integrated volume of various fluorescence regions were investigated. The results showed that although recycling during the rainy season increased the pollution load of organics and inorganic nitrogen in the process, enhanced coagulation would result in the overall fluorescence intensity of the treated water being 1.7% lower than that without recycling. It also affected the variation trend of HAMs formation potential in the water along the treatment process. Pearson correlation analysis indicated a significant correlation between aromatic protein-like substances (tyrosine-like), nitrate nitrogen concentration, UV254, and TCAM and total formation potential in the effluent from each treatment unit. Moreover, the integrated volumes of various fluorescence regions could effectively predict the formation potential of DCAM and TCAM. Overall, indirect recycling of production wastewater during the rainy season has minimal impact on the quality of finished water.
