目的了解克拉玛依市二次供水的水质情况,为卫生监督监测提供科学依据。方法收集该市2006—2008年的二次供水检测数据,并对其进行分析和评价。结果3 a共检测样品44份,合格率为38.64%,其中2006年合格率为62.5%,2007年合格率为40.0%,2008年合格率为30.8%。结论克拉玛依市二次供水合格率较低,影响合格率的主要因素是游离余氯、菌落总数和浑浊度。今后应加强对二次供水的监督检测。
Objective To understand the quality of secondary water supply in Karamay City and provide a scientific basis for health supervision and monitoring. Methods The data of secondary water supply in the city from 2006 to 2008 were collected and analyzed and evaluated. Results A total of 44 samples were detected in 3 years, with a pass rate of 38.64%, of which 62.5% were passed in 2006 with a pass rate of 40.0% in 2007 and a pass rate of 30.8% in 2008. Conclusion The qualified rate of secondary water supply in Karamay City is relatively low. The main factors affecting the pass rate are residual free chlorine, total number of colonies and turbidity. In the future, the supervision and inspection of secondary water supply should be strengthened.
