摘要:
以宁波市J水厂为研究对象，分析2025年台风“竹节草”期间原水水质突变特征，探究前置臭氧/双氧水（O3/H2O2）高级氧化工艺在此期间的处理效能与作用机理。结果表明，台风导致原水浊度骤升至280 NTU，高锰酸盐指数峰值达4.20 mg/L，台风当天有机物数均分子质量从台风前的800 u增至1 145 u，具有高浊、高有机物、高分子质量的复合污染特征。启用O3/H2O2工艺后，工段出水荧光体积积分削减26.8%，数均分子质量降低26.2%，小分子组分比例增加，同时通过氧化-混凝协同作用，沉淀池出水浊度控制在1 NTU以下，全流程溶解性有机物（DOM）削减率从常规工艺的36.3%提升至82.0%。工艺效能缘于O3和羟基自由基（·OH）对有机物的直接降解，以及氧化生成的含氧官能团与无机颗粒物表面络合吸附，实现有机物直接去除+协同分离的双重效果。这为同类型水厂应对台风期间水库原水水质突变提供了技术参考与运行依据。
Abstract:
This study focused on the J water plant in Ningbo, analyzing the characteristics of raw water quality fluctuations during typhoon Zhujiecao in 2025. The treatment efficiency and mechanism of the pre-ozone/hydrogen peroxide (O3/H2O2) advanced oxidation process during this period were investigated. The results showed that the typhoon caused a sharp increase in raw water turbidity to 280 NTU, with a peak permanganate index of 4.20 mg/L. On the day of the typhoon, the number-average molecular weight of organic matter increased from 800 u (pre-typhoon) to 1 145 u, exhibiting a complex pollution profile characterized by high turbidity, high organic matter concentration, and high molecular weight. After the O3/H2O2 process was activated, the fluorescence volume integral of the effluent was reduced by 26.8%, and the number-average molecular weight decreased by 26.2%, accompanied by an increase in the proportion of small-molecule fractions. Through the synergistic effect of oxidation and coagulation, the effluent turbidity from the sedimentation tank was controlled below 1 NTU. The overall dissolved organic matter (DOM) removal rate increased from 36.3% in the conventional process to 82.0% in the full process. The process efficacy was attributed to the direct degradation of organic matter by ozone and hydroxyl radicals (·OH), as well as the complexation and adsorption of oxygen-containing functional groups generates by oxidation onto the surface of inorganic particles. This dual effect of direct removal + synergistic separation provides technical reference and operational guidance for similar water treatment plants dealing with water quality variations in reservoir raw water caused by typhoons.
