Abstract: The problem of excessive manganese content in reservoir water is common in our country, especially in drinking water source area. It is very important to explore how to solve the problem of excessive manganese content in reservoir water. This paper mainly used the methods of field investigation, sampling and testing to analyze, find out the reasons of the manganese content exceeding the standard in Shuangqiao reservoir, and put forward the treatment measures to solve the problem of the manganese content exceeding the standard in the water source area, so as to provide reference for solving the problem of the manganese content exceeding the standard in the water source area.
Keywords: Shuangqiao Reservoir;excessive manganese content;treatment measures
1 研究背景
錳元素(Mn)廣泛分布于地質環境中,如巖石、土壤或沉積物等自然介質均含有錳元素。該元素也是人體代謝必不可少的微量元素,每天攝入量為2~5mg,而人體的吸收率為5%~10%,主要通過食物和飲用水等攝入。錳可促進骨骼的生長發育,保護細胞中細粒體的完整,保持正常的腦功能,維持正常的糖代謝和脂肪代謝,可改善肌體的造血功能。若人體缺錳,可能會影響生長發育,導致畸形。但攝入過多,會造成錳中毒,損害人體的運動機能和神經系統,嚴重者可能出現帕金森綜合癥和男性生殖系統疾病[1]。水是生命之源,安全潔凈的飲用水源是地區經濟建設和社會發展的基礎,也是人民對美好生活向往的一項重要保障指標。若飲用水源錳含量超標,可能會導致各種疾病發生。此外,錳的氧化物會在輸水管道內壁慢慢沉積,對供水管網造成影響,錳元素超標還會增加水廠水處理工藝的難度和處理成本。
