Study On Total Amount Control Of Water Pollutants In Juxian County

With the development of society and economy, the pressure of protection of water environment is increasing, and it is also have higher requirements for the Environmental management. the total emission of water pollution is a important task for the water environmental protection, and it is also the basis for water standards and water environmental quality improvement. but the value of water environmental capacity and water pollutant emissions is the technical basis for total water pollution emission control and water environmental management, and it has also an important influence for the relevant policy.This paper takes Juxian water environment as the research object, according to the water quality monitoring data of Juxian environmental monitoring station, use the method of index to evaluate the water quality status of Juxian, and it is make sure that COD/NH3-N is the mainly water pollution of Juxian.Through the analysis and comparison of three kinds of water environmental capacity prediction model, The definition of the water environmental capacity model based on more suitable for Juxian within the river Shu river system, and make a prediction for Juxian water environmental capacity According to the hydrological monitoring data of Juxian hydrological station, and make sure that the water environmental capacity of COD on the driest month, the dry season, dry season are 261.11t/a、402.81t/a、477.90t/a;NH3-N are 12.01t/a、18.52t/a、21.98t/a.Using the calculation method of different industry to predict the total emission of COD/NH3-N of 2014and 2015 are 20548t/a、1888t/a;21143t/a.1948t/a. To complete the target of the total emission reduction purpose of 12th Five-Year Plan, the reduction of COD/NH3-N in 2014 and 2015 are 2925t、284t; 411 It.394t.On the basis of prediction in water environmental capacity and water pollution emissions, it can be Put forward the countermeasures to the water pollution control measures in Juxian from policy and mangment.
