目的了解库尔勒市近3年生活饮用水的现状及水质情况,为改善市区饮水质量提供合理建议。方法 2010—2012年年底连续3年对库尔勒市现场抽检和送检的共1 875份的水源水、出厂水、管网末梢水和二次供水进行监测,采用国家标准进行评价。结果水源水、出厂水、管网末梢水和二次供水的合格率分别为100.0%、99.73%、97.58%和97.05%。其中管网末梢水的监测指标中游离余氯的合格率较低(97.58%),二次供水的监测项目中细菌总数的合格率较低(97.29%)。结论管网末梢水和二次供水的水质合格率较低,供水部门应加强管理,严格消毒,对管网要定期检查维修。卫生监督监测部门要加强监管力度,提高监测频次。
Objective To understand the current situation and water quality of drinking water in the past three years in Korla, and to provide reasonable suggestions for improving drinking water quality in urban areas. Methods A total of 1 875 water source, ex-factory water, peripheral pipe network and secondary water supply were sampled and inspected in Kuerle City for three consecutive years from the end of 2010 to the end of 2012, and were evaluated by national standards. Results The pass rates of water source, ex-factory water, pipe-end water and secondary water supply were 100.0%, 99.73%, 97.58% and 97.05% respectively. Among them, the qualified rate of residual free chlorine in the monitoring index of the peripheral water of the pipe network was low (97.58%). The qualified rate of the total number of bacteria in the secondary water supply monitoring project was low (97.29%). Conclusion The qualified rate of the water quality of the peripheral water of the pipe network and the secondary water supply is relatively low. The water supply department should strengthen the management and strictly sterilize the pipe network and regularly check and repair the pipe network. Health supervision and monitoring departments to strengthen supervision and improve the frequency of monitoring.
