楚雄市城市河道水体微生物指标测定与分析

Measurement and Analysis of Microorganism Indexes of Urban River Water in Chuxiong

目的 :调查楚雄市城市河道水体中微生物指标现状。方法 :于2012年11月(枯水期)和2013年8月(丰水期),分别对该城市河道上、中、下游三个水域采集水样,对其水温、pH值、浑浊度和微生物指标进行测定。结果 :丰水期微生物含量明显高于枯水期(P细=0.038<0.05,P肠=0.037<0.05),中游水域微生物含量最高。结论:楚雄市城市河流水体中微生物含量超标,微生物污染严重。

Objective ：To investigate the status of microbial indicators in urban river water in Chuxiong.Methods ：In November 2012（dry season）and August 2013（wet season） ,the water samples were collected from the river course,middle and lower reaches of the city,and the water temperature,pH value,turbidity and microbial indicators were measured.Results ：The microbial content was significantly higher in the high water period than in the low water period（P fine=0.038 〈 0.05,P intestine=0.037 〈 0.05）.Conclusion： the microbial content of the urban river water in Chuxiong is over standard and the microbial contamination is serious.
