水库水中锰超标的情况在我国地表水湖库型饮用水源地较为普遍,多发生在夏季7月下旬至9月初,锰是人体内不可缺少的微量元素,人体内的锰主要来源于食物和水,然而过多的摄入就会给身体带来危害,引起锰中毒,文章主要对驻马店市自来水公司供水水源地板桥水库夏季出现锰超标现象的原因进行分析,指出水库中锰含量的分布特征,其与水的温度、溶解氧等因素的变化有关,以及内部与外界因素带来的影响,并针对水库水中锰超标问题,提出相应的防治措施。
Excessive levels of manganese in reservoir water are more commonly found in drinking water sources of surface water lakes and reservoirs in China. They occur mostly in the late summer of July to the beginning of September. Manganese is an indispensable trace element in the human body. Manganese in the human body mainly comes from food and However, too much intake will bring harm to the body and lead to manganese poisoning. The article mainly analyzes the reason of Mn exceeding the standard in summer in Shibaqiao Reservoir, the water supply source of Zhumadian Water Company, and points out the distribution characteristics of manganese in reservoirs , Which is related to the change of water temperature, dissolved oxygen and other factors as well as the internal and external factors, and puts forward corresponding prevention and control measures in response to the excessive manganese in reservoir water.
