环境汞污染及对人之危害,久已被人们所重视。长春气象仪器厂是以生产水银气压表为主的工厂,已有三十年的历史。该厂汞车间年用汞量为4—5吨,损失率为2.9％,回收率约80％,每年约有22.3公斤汞流失,主要以废气、废水形式污染环境。自1980年以来,该厂采取曝气法处理含汞废水;高锰酸钾净化法(斜孔塔)处理含汞废气的新技术,大大减少了汞对周围环境的污染。 Environmental mercury pollution and harm to people, people have long been valued. Changchun Meteorological Instrument Factory is the production of mercury barometer based factory, has 30 years of history. The plant annual Mercury mercury plant 4-5 tons, the loss rate of 2.9%, the recovery rate of about 80%, about 22.3 kg of mercury each year, mainly in the form of waste gas, waste water pollution of the environment. Since 1980, the plant has adopted the aeration method to treat mercury-containing wastewater; the new technology of potassium permanganate purification method (inclined pore tower) to deal with mercury-containing waste gas has greatly reduced the pollution of mercury to the surrounding environment.
