硒是人体必需的微量元素,对人体健康有着重要的影响,硒含量过高或过低都会引起疾病。同时,硒是多种人体酶中不可少的元素,流行病学研究表明,克山病、某些肿瘤的发病率与人体血硒水平呈显著负相关系,艾滋病(ADIS)患者血硒水平明显低于正常人群。湘西自治洲锰矿产量居全世界第二位,并且每生产1t电解锰,废渣为8～10t,污水为300t,未经任何处理直接排放于河中,为此,必须对废水中
Selenium is an essential trace element of the human body, has an important impact on human health, selenium content is too high or too low will cause disease. At the same time, selenium is an indispensable element in a variety of human enzymes. Epidemiological studies have shown that Keshan disease, the incidence of certain tumors and the blood selenium levels of the human body showed a significant negative correlation, and the blood selenium level of AIDS patients (ADIS) Lower than the normal population. The output of manganese ore in Xiangxi Autonomous Region ranks the second in the world, and every 1t electrolytic manganese is produced, the waste residue is 8 ~ 10t, the sewage is 300t, and is directly discharged into the river without any treatment. Therefore,
