由于漂白粉、三氯异氰尿酸等含氯消毒剂具有杀菌力强、价格低廉、使用方便等优点,因此氯化消毒法仍然是水产养殖中常用的消毒方法。然而,随着养殖水环境的日益恶化,氯化消毒法的副反应和缺陷也日益明显:如氯化消毒效果容易受到pH值、水温等因素的影响;除腺病毒外,对其它病毒的杀灭力不强;长期使用容易引起微生物产生耐药性;更为严重的是各种氯化消毒的氯系消毒剂均会与水中有机物反应而生成具有致突变及致癌作用的三卤甲烷类物质。二氧化氯(ClO_2)以其卓越的性
As chlorine dioxide disinfectant such as bleaching powder and trichloroisocyanuric acid has the advantages of strong bactericidal power, low price and convenient use, the chlorination disinfection method is still the common disinfection method in aquaculture. However, with the worsening of aquaculture water environment, the side reactions and defects of chlorination disinfection method are also increasingly obvious. For example, the disinfection effect of chlorination is easily affected by factors such as pH value and water temperature. In addition to the adenovirus, the killing of other viruses Is not strong; long-term use easily lead to microbial resistance; more serious is that a variety of chlorinated disinfectant chlorine disinfectants will react with organic matter in the water to produce mutagenic and carcinogenic trihalomethanes . Chlorine dioxide (ClO 2) for its superiority
