摘要
目的了解广东省某市水源水水质卫生状况及变化趋势,为水源水卫生管理提供科学依据。方法于2003—2018年对广东省某市水源水进行监测,分析不同年份、水系和季度间的差异。结果2003—2018年广东省某市水源水的合格率为13.13%(63/480),监测项目合格率为91.94%(11549/12585),总体均有升高的趋势;五大水系最高合格率为25.56%(34/133),第一至四季度监测项目的合格率分别为91.27%(2947/3229)~92.53%(2888/3121);水源水中粪大肠菌群、铁、锰、氨氮、镍合格率分别为27.04%(106/392)、39.38%(189/480)、62.29%(299/480)、67.23%(318/473)、86.08%(303/352),其余指标合格率均在94%以上。结论广东省某市水源水的水质逐年改善,应进一步加强粪大肠菌群、铁、锰、氨氮和镍的检测,做好水源防护。
Objective To understand the quality and changing trend of source water in a city of Guangdong.Methods The sanitary quality of source water in a city of Guangdong was monitored during 2003-2018,the variation of which between different years,river systems and seasons were analyzed.Results The qualified rate of source water in a city of Guangdong province was 13.13%(63/480),and the qualified rate of monitoring projects was 91.94%(11549/12585),both of which had increase trend.The highest qualified rates of five river systems was 25.56%(34/133)respectively.The qualified rates from the first quarter to the fourth quarter were 91.27%-92.53%.The qualified rates for fecal coliform,iron,manganese,ammonia nitrogen,nickel in source water were 27.04%,39.38%,62.29%,67.23%,86.08%respectively,and above 94%for others.Conclusion The quality of source water of this city in Guangdong is getting better.The monitoring on fecal coliforms,iron,manganese,ammonia nitrogen,nickel in source water should be strengthend,as well as the protection of source water.
