十二、锰锰和铁在天然水中可以同时发现,或由于工业废水或矿水污染所致,水中锰普通的存在形式是重碳酸亚锰、硫酸亚锰或胶状的有机盐,锰在地下水较地面水为常见,锰对于生活饮用水的危害比铁较大,含量超过0.1mg/L 就能污染衣服,且使水浑浊并带有异味。锰细菌也能在管道中繁殖,饮用水允许最高浓度不超过0.1mg/L。 Manganese manganese and iron can be found in natural water at the same time, or due to industrial wastewater or mineral water pollution, manganese is generally present in the form of manganous bicarbonate, manganous sulfate or colloidal organic salts, manganese in groundwater More common than surface water, manganese is more harmful to drinking water than iron, with contents exceeding 0.1 mg / L can pollute clothes and make the water cloudy and smelling. Manganese bacteria can also breed in the pipeline, drinking water to allow the maximum concentration does not exceed 0.1mg / L.
