Abstract


Serious pollution of the water environment and water resources are becoming scarce, leading to the deterioration of the regional ecological environment, restricting regional economic and social development speed, affecting the quality of economic and social development of a sensitive factor. \Therefore, the quantitative prediction provincial COD emissions, mining COD reduction potential, seek COD reduction measures, it is particularly urgent and necessary. In this study, environmental science, economics, statistics and other disciplines of knowledge, using a combination of quantitative and qualitative, theoretical and empirical research combining research methods, the introduction of the concept of the learning curve and the emission reduction potential of the provincial total COD discharge for quantitative prediction, building COD reduction potential model, and propose specific emission reduction measures. The main results are as follows: (1) define the COD reduction related concepts, nature and content; From an economic point of view, the support of COD reduction systems analysis theory, summarized COD reduction policies supporting role. Explicitly states that \(2) to establish a provincial domain COD emissions quantitative forecasting methods. Using the basic parameters of Hebei Province, Hebei Province, \. (3) systematic analysis of the critical path COD reduction. In Hebei Province, quantitative analysis of pollution reduction projects, industrial restructuring emission reduction and environmental management are three ways to reduce emissions performance and cost, from an economic, technical and management aspects of the system reveals a variety of ways superior reduction inferior and application conditions. (4) in-depth analysis of Hebei economic structure and social development continued reduction of COD key constraints. Combined Hebei COD reduction targets and surface water environmental function, in accordance with the principles of technical and economic reach of Hebei COD pressures conducted a comprehensive analysis. (5) the scientific definition of the concept of COD reduction potential, based on the whereabouts of drainage system and build a provincial emission reduction potential COD model. To emission reduction targets as constraints, quantitative calculation and analysis of the COD reduction potential of different scenarios, a clear priority mining reduction potential; explore the potential of the proposed specific measures and demonstrate their technical and economic feasibility for regional conservation to provide basis for decision making. (6) focuses on the emissions trading system and the COD reduction of investment and financing measures. Proposed based on the \Papers main innovations: the introduction of COD discharge environment and COD reduction potential learning curve concept, the establishment of provincial total COD discharge quantitative forecasting methods and COD reduction potential quantitative prediction model. This study not only has important theoretical significance, but also improve the water quality of the environment, and promote healthy economic and social development has important practical significance.
