德兴铜矿生活饮用水源中铁、锰含量的调查及提高水质的对策

Investigation on the content of iron and manganese in life potable water of Dexing Copper Mine and the counter measures taken for improvement of its water quality

德兴铜矿生活饮用水源来自于婺源叶坑水库和乐安江。由于乐安江水质不定期受到污染 ,主要危害物质是挥发酚等有机毒物 ,因此德兴铜矿自来水公司主要取用叶坑水库水作为生活饮用水。而叶坑水库水随季节的变化 ,铁、锰含量的变化较大 ,有时超标严重 ,有时符合标准。经过 2年的调查研究 ,总结了铁、锰含量随季节变化的规律 ,从而在水处理过程中采取了相应的对策 ,确保了出厂净化水符合国家生活饮用水卫生标准 ,维护了生活在德兴铜矿地区六。

Water from Yekeng Reservoir of wuyan county and Le An River are the sources of life potable water of Dexing Copper Mine (DCM).Water from the later is subjected to nonregular pollution ,and the main harmful substance containing in water is organic poison such as volatilizable phenol etc.so water from the former is used as the main source by Running Water Company of DCM. However,its water quality varies with season.especially the content of iron and manganese vary greatly.Sometimes it is severely beyond the standard and sometimes suitable for drinking.The regular pattern of such variation has been discovered through two year's investigation,and therefore the appropriate measures are taken for the water processing, which ensures, the purified water from the waterworks up to the hygienic standard of national life potable water and also safeguard the security of drinking water for sixty or seventy thousand inhabitants in this area.
