摘要
Abstract
Based on the measured data of the studied area,the water quality status of Luxian County in Laixi River was evaluated by using the output coefficient model,the equal-standard-pollution-load method and etc,and combining with the water quality data and the literature data,determined the output coefficient,estimated the pollution load of COD,ammonia nitrogen,total phosphorus and analyzed the main source of pollutants in Luxian County Section.The results show that the water quality of the county is relatively poor,the total phosphorus is the primary pollutant in the whole basin.The COD pollution load is mainly derived from urban life and industrial production,accounting for 60％ of the total pollutants into the river.The ammonia pollution load is mainly from urban life and agricultural non-point source,accounting for 64％ of the total pollutants into the river.The total phosphorus pollution load is mainly from agricultural non-point source and livestock breeding,accounting for 75％ of the total pollutants into the river.It is proposed to further speed up the construction of urban life pollution control facilities,strengthen the pollution control of industrial enterprises,improve the prevention and control of agricultural pollution in rural areas,implement comprehensive river basin renovation and ecological restoration.关键词
