Abstract:
According to the pollution control process of the first-stage construction in the Eastern Route of South-to-North Water Diversion Project, the amounts of COD and ammonia discharge into the rivers in the Huaihe River Basin were analyzed from perspective of provinces and sections from 2002 to 2012 based on the planning year of 2000. The results showed that the pollution loads decrease significantly due to structural, engineering, and management discharge reductions. During the 10th five-year plan, the excessive growth of main pollutants discharge into the river was controlled within limits along the Eastern Route of South-to-North Water Diversion Projection (SNWD). Therefore, during the 11th five-year plan, pollution load along the route showed a substantial decline. The pollution load along the route reached the overall planning control objective in 2010 and pollution control and discharge effects had been strengthened in 2012, which laid a solid foundation for the water service of the first-stage engineering project in the Eastern Route of SNWD in 2013.
