摘要
锰是人体必需的微量元素,锰可呈可溶与浮悬形态存在于新鲜水中,生活饮用水中锰的污染来源主要为矿山开采、工业废水和废渣流入地表水、水源地网箱养鱼和内源性污染使锰含量呈季节性超标,地下水锰污染与周边环境相关。锰超标使饮用水的色、味变差,锰的氧化物易在管道内壁上沉积并引起"黑水"现象。常采用接触氧化法除锰。
Manganese is one of the essential trace elements in human body, it shows soluble phase or suspended state in fresh water. The sources of manganese pollution in drinking water mainly included mining, industrial wastewater and waste residue which inflowing the surface water, caging culture in water source area and endogenous pollution.This can make manganese content seasonal over standard.Manganese pollution in groundwater relates to the surrounding environment and the manganese in the drinking water over standard can make the water＇s color and taste becoming worse and the manganese oxides easily deposits on the pipe inner surface which cause BLACK WATER Phenomenon. It is often removing by Contact Oxidation Process.
