用氯气对饮用水消毒,会使水中的有机物发生氯代,生成有机含氯化合物,对人体有害,世界环保联盟即将全面禁止使用这种消毒方法,建议采用广谱性且具有强氧化性的高效消毒剂二氧化氯(ClO2),ClO2在室温下为黄绿色气体,熔点为-59℃,沸点为11℃,ClO2极易爆炸,生产和使用时尽量用惰性气体稀释,避免光照、震动、加热.
Disinfecting drinking water with chlorine gas will cause organic matter in the water to chlorinate and generate organic chlorine compounds. It is harmful to the human body. The World Environment Coalition is about to completely ban the use of this disinfection method. It is recommended to use a broad-spectrum and strong oxidizing efficiency. Disinfectant chlorine dioxide (ClO2), ClO2 is a yellow-green gas at room temperature, melting point is -59 °C, boiling point is 11 °C, ClO2 is very easy to explode, production and use as far as possible diluted with inert gas to avoid light, vibration, heating .
