摘要
目的全面摸清邢台市河流水环境质量现状,为制定河流返清工作方案提供科学依据。方法按照《生活饮用水卫生标准》GB 5749-2006进行检测,检测指标包括常规指标和氨氮(放射性指标不要求)。结果共调查邢台辖区内13条河流两岸饮用水226份,总体合格率为67.26%,不同井深饮用水结果差异有统计学意义(χ2=18.92,P<0.05),不同水源距离饮用水结果差异无统计学意义(χ2=0.49,P>0.05)。不合格指标主要有微生物指标、氟化物、氯化物、硫酸盐、溶解性总固体、总硬度和氯化物等。结论微生物指标和氟化物超标是河流两岸水质合格率低的重要原因,应加强饮用水消毒以及卫生管理,加强监测,提高居民饮用水卫生意识。
Objective To understand the current situation of river water quality in Xingtai, and to provide scientific basis for formulating river returning work program. Methods In accordance with the ＂ Healthy Drinking Water Standards＂ GB 5749-2006 for testing, the routine indexes and ammonia nitrogen（ radioactivity index were not required） were monitored. Results A total of 226 drinking water samples from 13 rivers in the Xingtai were investigated. The overall qualification rate was 67.26%. There were statistical significant differences in the results of drinking water at different well depths （X^2 = 18.92, P〈0.05）. There was no statistical significant difference between drinking water results for different water sources （X^2 = 0.49, P〉0.05）. Unqualified indicators included microbial indicators, fluoride, chloride, sulfate, dissolved total solids, total hardness and chloride. Conclusion Microbiological indicators and fluoride exceed standard are the important causes of the low qualified rate of water quality on both sides of the river. It is necessary to strengthen the disinfection and sanitation management of drinking water, strengthen the monitoring and improve the awareness of drinking water sanitation.
