氯气是一种有强烈刺激性的黄绿色气体,易溶于水。与水反应后产生的次氯酸,具有很强的氧气性,能够杀死水里的细菌,而且货源充足,价格低廉,设备简单,出厂水进管网后还能保持一定的剩余氯,可防止管网中再度细菌繁殖。剩余氯的测定也比较简单,很快得出结果,便于及时增减加氯量,保证水质。所以加氯消毒法,在饮用水消毒、污水消毒上得到了广泛的应用。 同时,氯气又是一种特殊强烈刺激的窒息性的气体,对人体的生理组织有害。特别是对呼吸系统和眼粘膜伤害很大,空气中氯的浓度高时,可引起气管痉挛或
Chlorine is a yellowish-green gas that is highly irritating and soluble in water. Hypochlorous acid generated after reacting with water has strong oxygen and can kill bacteria in the water. Moreover, it has ample supply, low cost and simple equipment. After leaving the pipe network, it can still maintain a certain amount of residual chlorine. Prevent bacteria breeding in the pipe network again. The determination of residual chlorine is also relatively simple, and results are quickly obtained, which facilitates the timely increase and decrease of chlorination and ensure water quality. Therefore, the chlorination method has been widely used in drinking water disinfection and sewage disinfection. At the same time, chlorine is a particularly strong suffocating gas that is harmful to the body’s physiological tissue. In particular, it is harmful to the respiratory system and eye mucous membranes. When the concentration of chlorine in the air is high, it can cause tracheal spasm or
