摘要:
为应对直链藻污染对水厂运行的冲击，某给水厂对预氧化、强化混凝及协同工艺的除藻效能进行评估，重点考察了藻密度、pH、Zeta电位对处理效果的影响。结果表明，强化混凝工艺对藻密度低于105 个/L的水体除藻率达98.71%；加氯预氧化工艺在藻密度为105~106 个/L时除藻率提升至99.19%；预氧化-强化混凝协同工艺对藻密度为106~107 个/L的原水可保持99.95%的除藻率。机理分析表明，水体pH与Zeta电位呈负相关性，调节pH至7.5~8.0范围可有效提高Zeta电位，进而显著提升混凝沉淀效果。黄原胶助凝可高效去除水中多肽、蛋白质及腐殖酸类有机质，其通过氢键结合、静电吸引和吸附架桥等作用促进絮体形成与沉降。研究成果为高藻期水厂工艺调控提供了理论依据。
Abstract:
To address the operational challenges posed by Melosira granulata contamination in water treatment plants, this study evaluated algae removal efficiency through pre-oxidation, enhanced coagulation, and their hybrid processes, with a focus on algal density, pH, and Zeta potential. Experimental results demonstrated that enhanced coagulation achieved a removal rate of 98.71% for algae in raw water with algal density below 105 cells/L. Chlorine-based pre-oxidation improved removal efficiency to 99.19% at algal densities of 105-106 cells/L, while the hybrid pre-oxidation-coagulation process maintained 99.95% removal efficiency even under high algal loading (106-107 cells/L). Mechanistic analysis revealed a negative correlation between pH and Zeta potential. Adjusting pH to 7.5-8.0 effectively increased Zeta potential, thereby enhancing coagulation efficiency. Xanthan gum as a coagulant aid significantly removed peptides, proteins, and humic acids through hydrogen bonding, electrostatic attraction, and adsorption-bridging effects, promoting floc formation and sedimentation. These findings provide date support for process optimization in water treatment plants during algal bloom periods.
