本项目针对超滤处理阴离子表面活性剂诱发含藻水开展含藻水水质特征解析，污染界面机制探究并提出组合工艺调控策略。超滤工艺是一种高效的除藻技术，但含藻水成分复杂，其污染机制受含藻水中藻细胞形态和藻源有机物性质等因素影响。申请人前期已针对不同组分藻源超滤污染机制和超滤组合工艺除藻展开相关探讨。阴离子表面活性剂是常见的城镇和农村面源污染物，是引起水体富营养化的重要环境因子。藻类生长规律、藻细胞活性、表面电荷和有机物性质受环境因素影响，因此有必要监测阴离子表面活性剂诱发的含藻水污染物累积规律，解析含藻水水质特征，并进行水质健康风险评估。阴离子表面活性剂疏水基团的吸附作用改变污染层界面作用力，因而有必要探讨阴离子表面活性剂与藻源污染物界面行为和复合膜污染机制。此外，超滤预处理亦会对阴离子表面活性剂诱发含藻水污染物组成和结构产生影响，因而有必要探讨超滤组合工艺的污染物迁移转化规律，提出高效调控措施。

This project aims at the ultrafiltration treatment of anionic surfactant induced algae-laden water. The characterization of algae-laden water and interface fouling mechanism was investigated, and the combination process for control strategy was proposed. Ultrafiltration is an efficient algae removal technology, but the composition of algae-laden water is complicate. The fouling mechanism is impacted by the morphology of algae cells and the property of algae-derived organic matter. The applicant has already carried out related discussions on the ultrafiltration fouling mechanism and membrane combination process for algae removal. Anionic surfactant is a common non-point source pollutant in urban and rural areas, and is one of the important pollutant that causes eutrophication. Algae growth law, algae cell activity, surface charge and organic matter properties are impacted by environmental factors. Therefore, it is necessary to identify the water characteristics and conduct drinking water safety assessments of anionic surfactant induced algae-laden water. The hydrophobic group of surfactants adsorb on the surface of algae cells, thereby changing the interface force of the fouling layer. It is necessary to explore the interface behavior of anionic surfactants and algae-derived foulants and the formation mechanism of membrane fouling. In addition, the ultrafiltration pretreatment process also impacts the composition and structure of anionic surfactant induced algae-laden water. Therefore, it is necessary to explore the migration and transformation laws of foulants in the ultrafiltration combination process and propose efficient membrane fouling control measures.
