基于常规饮用水工艺羟基自由基处理高藻水
Treatment of algae bloom water using · OH based on conventional drinking water process
摘要
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 from25.3 × 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-1in 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.关键词
