摘要
目的掌握2014年-2018年抚州市城市生活饮用水水质状况,探讨影响生活饮用水安全的主要因素,为相关部门制定有关决策提供重要的科学依据。方法对抚州市2014年-2018年饮用水监测分析,采用SPSS 21.0软件对监测数据进行统计和分析,组内合格率差异性统计意义采用卡方检验进行判别。结果抚州市城市生活饮用水近几年合格率逐年增加趋势,2018年合格率高达96.26%;枯水期与丰水期对合格率无较大影响;水类型合格率有差异,末梢水(88.24%)>二次供水(85.55%)>出厂水(72.35%);南丰、金溪、宜黄等地区需重点关注;微生物和游离余氯2个指标不合格发生率较大。结论需科学使用消毒剂,既要保证消毒效果,又要减少游离余氯含量;加强对新的消毒试剂的研发和水处理技术的开发,积极改善水处理工艺。同时,政府有关部门要强化水质监测和工作督导,加大水源的保护力度,加强饮用水安全知识的宣传。
Objective To analyze the quality of urban drinking water in Fuzhou City from 2014 to 2018,and explore the main factors to the safety of drinking water,so as to provide scientific basis to make relevant decisions for relevant government.Methods Drinking water monitoring and analysis were conducted in Fuzhou City from 2014 to 2018,the statistic analysis for the data of monitoring were carried out by SPPS 21.0,and the Chi-square test was used to distinguish the difference of pass rate in the group.Results It can be revealed that the qualified rate for drinking water increased year by year in recent years,and the qualified rate was 96.26%in 2018;there was no significant differences for qualified rate of drinking water between the raining seasons and dry seasons.The qualified rates of water types was peripheral water(88.24%)>secondary water supply(85.55%)>ex-factory water(72.35%);Nanfeng,Jinxi,Yihuang and other areas need to take more concerns on quality of water;compared to other indicators,the unqualified rates for microorganism and residual chlorine indicators were relatively high.Conclusion It is necessary to reasonably use disinfectants,which can ensure the efficiency of disinfection and reduce the free residual chlorine content;it is important to strengthen the research,to explore new disinfection reagent,to develop novel water treatment technology and to improve water treatment technology.At the same time,the government should take more efforts to protect water sources,to propagandize the drinking water safety knowledge for public,and to formulate relevant supervision programs.
