- Abstract:
- Based on the the domestic and international literature review focusing on water environmental carrying capacity, along with the analysis on the water resources, water environment of the center town of Chunhua County(lake and river-based water scenic spot) in the valley which is located in the southern edge of the Loess Plateau, the zero-dimensional model suitable for the homogeneous mixing of pollutants was introduced on the quantitative analysis and estimation of the water environment carrying capacity of the center town of Chunhua County by applying the chemical oxygen demand(COD) as the main pollutant index. The results showed that the water environmental carrying capacity and its maximum allowable emissions of the chemical oxygen demand(COD) of the Center Town on Ganquan Lake Scenic Area of the Chunhua status year(2010) and the planning year(2020) were 0.007 3 kg/s(231.87 t/a) and 0.005 6 kg/s(176.66 t/a), respectively. The average annual dropping rate of COD emissions was 2.38% which was higher than the national target of the average annual dropping rate of COD emissions(1.60%) from 2011 to 2015. Consequently, measures of water quality protection and pollution control were proposed.
