Analysis of Water Pollution Status and Countermeasures for Prevention and Management in Tongbo River Basin,Liangping,Chongqing
This study utilizes the routine monitoring data of water quality in the Tongbo River Basin from 2016 onwards to assess the water quality of the basin.By integrating the production and discharge coefficients as well as empirical formulas,the presence of pollutants in the basin is accounted for.Furthermore,an analysis of the trend of changes in water quality and the primary pollutant loads is conducted to identify the underlying causes of pollution.Finally,based on these findings,countermeasures and recommendations are proposed.The results of water quality evaluation show that:since 2016,the overall water quality of Tongbo River Basin has been improving year by year,and in 2022,the annual average value of the water quality of Niujiaotan section will be improved to Class III,the annual average value of the water quality of Shangheba will be improved to Class II,and the rest of the sections will meet or be better than the requirements of the watershed function.Pollution load calculation results show that:Tongbo River Basin Chemical Oxygen Demand emission is the largest domestic pollution,followed by livestock and poultry pollution;ammonia nitrogen emission is the largest domestic pollution,followed by agricultural pollution;total phosphorus emission is the largest livestock and poultry pollution,followed by agricultural pollution;industrial sources of various types of pollutant emissions are small.By enhancing the living pollution management level,strengthening the control of surface pollution and industrial pollution management can further reduce the pollution load of the watershed,to ensure stable water quality standards.
