2011～2013年济南市某铁矿矿井水水质调查

Survey on the Quality of an Iron Ore Mine Water,Jinan City,2011-2013

目的了解某铁矿矿井水的水质状况,探索矿井水作为生活饮用水的优势。方法对某铁矿矿井水利用情况进行调查,收集2011-2013年该铁矿两个集中式供水单位的矿井水和济南市其他自备井水（以下均称自备井水）的水质检测资料,对2种生活饮用水水源的32项检测项目进行比较,采用SPSS 13.0进行统计分析。结果 2011-2013年共检测矿井水74份,合格62份,合格率为83.78%,不合格项目为：微生物指标6份,一般化学指标3份,毒理指标3份,各年合格率分别为82.14%、84.62%和85.00%;3年共检测212份自备井水,合格151份,合格率为71.22%,不合格的项目为：感官指标4份,微生物指标58份,一般化学指标超标60份,毒理指标不合格样品20份。结论济南市某铁矿矿井水出水稳定、未受污染、水质理化指标能够满足饮用水标准,各年合格率均高于全国集中式供水水质合格率。矿井水作为生活饮用水水源切实可行。

Objective To understand the quality of the iron ore mine water,and explore its advantagesas the sources of the drinking water. Methods A survey was made on the utilization of a certain ore mine water,water quality surveillance data were collected during 2011-2013 from the two centralized water supply units of mine water and other self-provided well water in Jinan city,comparison was made on the 32 testing items of 2kinds of drinking water sources,using the SPSS 13.0for statistical analysis. Results In detection of 74 samples of mine water during 2011-2013,62 were qualified,with a qualified rate of 83.78%,the unqualified items were microscopic biological indicators in 6,general chemical indexes and toxicological indexes in 3,with an annual qualified rate of 82.14%,84.62%,and 85.00% respectively;A total of 212self-provided well water were tested,151 were qualified,with a qualified rate of 71.22%,the unqualified items were sensory indexes in 4,microbial indexes in 58,general chemical indexes exceeding the standard in 60,toxicological indexes in20. Conclusion The water outlet of a certain iron mine in Jinan city is stable,and the water outlet is not polluted,the physical and chemical indicators of water quality can meet the drinking water standard,the annualqualified rate is higher than that of the national centralized water supply.Mine water as the water source of drinking water is practical and feasible.
