摘要:
新污染物广泛存在于地表水、地下水及饮用水中，现有饮用水处理工艺对其难以有效去除。为此，研究了家用终端掺硼金刚石薄膜电极装置耦合超声（BDD/US）对水中新污染物的去除性能，以敌草隆、阿特拉津（ATZ）作为目标污染物，以单独BDD电极体系作为对照，确定了BDD/US体系的最佳工作参数，对比了两种体系对目标污染物和总有机碳（TOC）的去除效果，并分析了降解机理和降解毒性。结果表明，US的加入提高了体系中的活性氧（ROS）水平，BDD/US体系对敌草隆和ATZ的降解率分别提高10.11%和17.94%；即使降低BDD电极体系电流，1.2 A/1.0 A BDD/US体系依旧能够达到1.5 A BDD电极体系对两种目标物的去除效果水平；敌草隆和ATZ在降解过程中急性毒性逐步降低。
Abstract:
Emerging contaminants are prevalent in surface water, groundwater, and drinking water, and current water treatment processes struggle to effectively remove these contaminants. To achieve this objective, the removal efficiency of emerging contaminants from water using a point-of-use boron-doped diamond (BDD) thin film electrode integrated with ultrasound (BDD/US) was investigated. Diuron and atrazine (ATZ) were selected as target contaminants, and the standalone BDD system served as the control group. The optimal operational parameters of the BDD/US system were identified through comparative analysis. The removal efficiencies of both systems regarding the target contaminants and total organic carbon (TOC) were evaluated, and the degradation mechanisms as well as potential toxic byproducts formed during the process were examined. The introduction of US into the system led to an increase in the level of reactive oxygen species (ROS). Consequently, the degradation efficiencies of diuron and ATZ in the BDD/US system were enhanced by 10.11% and 17.94%, respectively. Notably, even with a reduced current supplied to the BDD electrode, the BDD/US system operating at 1.2 A or 1.0 A achieved removal efficiencies comparable to those of the 1.5 A BDD system for both target contaminants. Furthermore, the acute toxicity of diuron and ATZ was observed to gradually decrease throughout the degradation process.
