摘    要:羟基自由基在液相中的氧化电势为2.8 V,能够破坏微生物通透性屏障,破坏病原微生物的蛋白质、酶和核酸,导致病原微生物的死亡.在现场进行的中水灭菌实验中,当药剂质量浓度为38.2 g/L,投加量为O.14 kg/t时,大肠杆菌杀灭率可达到99.9%以上.同时,水体中的COD降低50%、NH3-N降低35%.羟基自由基制备原料为空气、水和电解质溶液,在常温常压条件下进行,无三废排放,兼具安全性和环境友好性.实践证明:它是替代氯气消毒的优选消毒品种.

关 键 词:羟基自由基  中水处理  环境友好

Abstract:The permeability barrier of microorganisms,and protein of pathogenic microorganisms,enzyme and nucleic acid can be destroyed by hydroxyl radical whose oxidation potential is 2.8 V in liquid phase,leading to the death of microorganisms.The sterilizing rate of escherichia coli can be above 99.9% when the reagent concentration is 38.2 g/L and the feeding dosage is 0.14 kg/t.Meanwhile,the COD of the water body decreases by 50%,and the NH3-N by 35%.The preparation raw materials of hydroxyl radical are air,water ...
Keywords:hydroxyl radical  regenerated water treatment  environment-friendly
