摘要
[目的 ]了解和掌握大厂镇地区拟建取水口水源的水质情况。 [方法 ]在长江枯水期对该水源地按不同断面、不同层次、不同潮位及取水口断面不同位置的水样进行了监测 ,依据 GB3838- 1988《地面水环境质量标准》 类水质评价。 [结果 ]达标率为 90 .11%。超标项目为溶解性铁、五日生化需氧量 (BOD5 )、石油类、非离子氨和总大肠菌群。表层水样石油类含量显著高于中层和深层水样。不同潮位水样水质间无显著性差异。 [结论 ]该水源地枯水期水质基本达到 类标准 ,符合饮用水水源的卫生要求。
Objective]To understand the source water quality in the programmed location of water collection in Dachang county [Methods]The sanitary quality of the water samples were monitored during different tide periods in low water period of Yangtze River.The sampling locations were distributed in different sections and different depths of Yangtze River.Additionally,some sampling points in the section of programmed water collection location were selected.Data obtained were assessed according to the National Creteria for Environmental Quality of Surface Water (GB 3838 1988) for type Ⅱ water[Results]The qualified rate of water samples was 90 11% The parameters exceeding the national standard were soluble iron,5 day biochemical oxygen demmand,petrolic compounds,non ionic ammonia and total coliform Higher levels of petrolic compounds were found in water samples from surface layer of river compared with those from surface and deep layer of river No significant differences was observed in water quality of the water samples sampled during different tide period [Conclusion]The sanitary quality of the observed water source accorded with the standard for type Ⅱsurface water,as well as the requirement of drinking water source.
