Optimization Research In Total Amount Control Of Pollutants Based On The Emission Reduction Of Structure, Engineering, Management And Emission Trading

The increasing scarce environmental capacity and severe environmental pollution situation have greatly restricted the situation of China’s sustained and rapid economic growth, environmental issues have become one of the important factors affecting human survival and development. In allusion to current crisis of national environmental quality, China has clearly put forward the requirements about enhancing the reduction and governance of pollutant emission, implementing the main pollutant emission control in order to retard the trend of worsening environmental pollution in China. As the core idea of the environmental management of pollutants, the pollutant total emission control policies and environmental economic measurements were favored by governments. The combination of pollutant emission reduction pathway and emission trading system with a minimum social-economic development expense is the key study of pollutant total emission control and can improve the current status of pollution distinctly. In addition, due to some factors such as vast territory, the huge difference among regional economy, the different development level of regional economic and so on, resulting in more uncertainty during pollutants total emission control. How to solve such the uncertainly objectively and scientifically has become a research hotspot for us.Based on the pollutant total emission control theory and emission trading system, the paper have proposed the "3+1" total control mode from3kinds views of reduce emissions measures (structure, engineering, regulatory), established pollutants total control indication system based on structural, engineering, controlling emission and total control indication system based on the "3+1" pollutants total control model following the structure principle of the regional index System and various pollutants emission reduction measures which has highlighted the application operability of indication system; The total control optimization model system of regional main pollutant based on structural, engineering, controlling emission and "3+1" total control indication system have been established respectively by the traditional linear planning method and uncertainty optimization method with meeting the requirement of main pollutants emission situation during "11th Five-Year","12th Five-Year" total control planning and modeled total control indication system about main pollutants.Combining with the main pollutants total control indication system based on structural, engineering, controlling emission, the minimum regional pollutant emission reduction cost was regarded as objective function, the index level of pollutants total control indication system as decision-making variable,"12th Five-Year" pollutants total control objective as constraint, the certainty and uncertainty total control optimization of main pollutants modes were established by means of traditional linear method and interval uncertainty planning method respectively. After the selected parameters and constraints, Hunan Province was used for case study, the regional pollutant total control optimization scheme based on structural, engineering, controlling emission was obtained which can propose reasonable emission reduction advice for regional main pollutants total control. In view of regional main pollutants total control model system based on structural, engineering, controlling emission, the emissions trading was introduced to total control model, index level of "3+1" model total control indication system was regarded as decision-making variable, industry pollutant emission requirements and socio-economic development growth as constraints, minimum main pollutants emission reduction cost as optimization goal, the ultimate regional pollutants total control optimization scheme based on "3+1" pollutants total control indication system was obtained by means of interval mathematical planning method to optimize main pollutants emission reductions under the situation of structural, engineering, controlling emission paths and emissions trading which could provide scientific decision-making for regional pollutants total control from views of pollutants emission reduction and emissions trading. By comparing the certainty and uncertainty optimization scheme established by main pollutants total control model system which according to structural, engineering, controlling emission and "3+1" total control pattern respectively, the paper combined with existing emission reduction problems of regional main pollutants in case province to indicate main factors affecting the achievement of total control objective. The optimal scheme resulted from model system could guide industry total control, guarantee the implementation and improvement of regional main pollutants total control and provide scientific reference for achieving regional main pollutants total control objectives and formulating regional total control pathways.
