摘要: 我国水体的富营养化日益严重，水源地出现季节性藻类爆发现象，严重威胁饮用水安全。以厦门市莲坂水厂各工艺段出水为研究对象，采用大气压强电离放电产生羟基自由基（·OH），分别对水源水、混凝沉淀出水、砂滤出水进行处理，处理时间为4.5 s。当注入总氧化剂浓度为1.8 mg· L-1时，高藻浓度从25.3×104 cells · mL-1降到800 cells · mL-1；对混凝沉淀出水注入总氧化剂0.6 mg· L-1、砂滤出水注入0.2 mg· L-1时，藻细胞都未检出；·OH处理后CODMn、TOC及UV254均有明显降低，砂滤出水三卤甲烷小于8 μg·L-1；检测的各项指标均达到国家《生活饮用水卫生标准》（GB 5479-2006）。因此，·OH可快速有效安全地杀灭高藻，为我国高藻水源地饮用水卫生安全保障提供技术支撑。

Abstract: Due to the increasing eutrophication in China, harmful algae blooms often occur in water body periodically, which poses serious threats to drinking water safety. Using a strong ionization discharge technology at atmosphere pressure, ·OH was used to remove algae bloom. Other conventional process such as coagulation, sedimentation and sand filtration were applied respectively in the Lianban Water Plant in Xiamen (China). The total reaction time required in the three water processes was only 4.5 s. When the total reactive oxidant (TRO) concentration injected to algae bloom water was 1.8 mg·L-1, the algae content was decreased by ·OH from 25.3×104 cells·mL-1 to 800 cells·mL-1. When the TRO that was injected into coagulation, sedimentation and sand filtration water achieved 0.6 mg·L-1 and 0.2 mg·L-1, respectively, the algae contents were not detected (ND) in treated effluents. At the same time, water quality in CODMn, TOC and UV254 were decreased and the disinfection by-products(DBPs) such as, trihalomethanes (THMs) concentration was lower than 8 μg·L-1 in treated effluents. The treated effluent, resulting from this technology, met the requirement of the National Drinking Water Standards (GB 5479-2006). Therefore, ·OH was effective and safe to remove freshwater algae without further treatment being required.
