摘 要:为全面了解航食基地——北京市大兴区长子营镇的河道水质,对镇域内的4条主要河道凤河、凤岗减河、旱河和岔河进行了水质调查,并采用综合污染指数法对河道水质进行了评价。结果表明:镇域内河道主要污染物有机物(化学需氧量)、氮(总氮)和磷(总磷)平均值分别为122、22.3和1.3 mg/L,均超过《地表水环境质量标准》(GB3838-2002)的V类标准限值;其中,凤河、凤港减河污染尤为严重。水质评价结果表明,4条河流的综合污染指数均超过1,其中,凤岗减河综合污染指数达到了15.01,污染程度最为严重。另外,对河道断面水质分析表明,部分河道在镇域内水质有恶化趋势,需从严控制污染源的污染物排放。With the aims at full understanding of the river water quality in the aviation food base in Zhangziying Town,Daxing District,Beijing City,water quality of the 4 main rivers(Fenghe River,Fenggangjianhe River,Hanhe River and Chahe River)was investigated.Comprehensive pollution index evaluation method was used to evaluate the river water quality.The results showed that the average values of organic pollutants(Chemical Oxygen Demand),nitrogen(total nitrogen)and phosphorus(total phosphorus)of the 4 rivers were 122,22.3 and 1.3 mg/L respectively,all exceeding the Class V standard limits in the Environmental Quality Standard for Surface Water(GB3838-2002).Among them,the pollution of Fenghe River and Fenggangjianhe River were particularly serious.The results from water quality evaluation indicated that the comprehensive pollution index of the 4 rivers were all over 1 and that of Fenggangjianhe River even reached to 15.01,suffering most serious degree of pollution.Furthermore,water quality analysis of the river sections showed that the water quality of some rivers tended to be deteriorated in the town area,so it is necessary to strictly control the discharge of pollutants from pollution sources.
