内蒙古自治区集宁区后备水源地地下水水质分析与评价

Analysis and Evaluation of Groundwater Quality for Jining District Reserve Water Source in Inner Mongolia Autonomous Region

为全面认识和掌握内蒙古集宁区后备水源地的水质状况,对2009年采集的水样进行检测,根据水质分析结果和细菌分析资料,以物理指标、化学指标、毒理学指标、细菌学指标为评价因素,对地下水水质(生活饮用水)进行分析评价.结果表明,集宁区地下水有些项目指标有不同程度的超标,特别是硝酸盐指标超标严重,细菌总数均未超标,该区地下水必须经过处理后才符合饮用水水质标准.

To fully understand and master the water quality of reserve water source in J ining, by using water samples of 2009 for testing,according to the results of the analysis and bacteriological analysis of water quality data and physical indicators, chemical indicators, toxicological indicators, bacteriological indi- cators for the evaluation factors, groundwater quality （drinking water） were analyzed and evaluated. The evaluation results show that some items of the groundwater appear varying degrees of overweight indica- tors, particularly nitrates exceeded the limitation seriously, and bacterial count did not. The area of ground- water must be processed before it meets drinking water quality standards.
