Performance Evaluation Of Source-controlling And Emission Reduction For Surface Water Major Pollutants

During the "eleventh five-years" the Liao Rive breakthroughs in a number ofpollution control key technical about chemical, light industry, metallurgy, textile,pharmaceutical and other five important industries, and achieved many technologicalachievements. We Objective evaluate the performance of Source-controlling andemission reduction technology was adopted on Liao River, it is beneficial forscientific summarize actual. Performance of Source-controlling and emissionreduction during the " eleventh five-years ",also provide scientific basis on improvethe total emissions basin performance management level and formulate a reductionprogram for "twelfth five-years ".On the basis of reading a lot of literature at home, this thesis summarized thestudy on energy saving performance evaluation system at home and abroad and thecurrent comprehensive evaluation methods which were in common use. Then itdescribed the meaning of performance evaluation of source-controlling and emissionreduction and the other related theories.According to the characteristics of the main pollution sources in the source areasof Liao River, this thesis studied the status of source-controlling and emissionreduction in the source areas of Liao River since the water project was carried out,then analyzed the main factors of performance evaluation of source-controlling andemission reduction. The index system of performance evaluation of the surface watersource-controlling and emission reduction in the source areas of Liao River wasstructured from the performance of the water environmental situation, theperformance of source-controlling and emission reduction technology and theperformance of management.According to the principle of fuzzy evaluation and index features, the studyestablished entropy fuzzy evaluation model. Firstly calculate the weight of variousindicators by entropy method, and then used mathematical methods to determine theevaluation matrix, finally a combination of both weights and the evaluation matrix. Illustrated by the example of Si-ping of Liao river source area,and according to thealmanac data for2008to2010, evaluate the performance of Source-controlling andemission reduction,and obtain three-year performance sorting, the performance in2009is the best,and the performance in2010is better than the performance in2008.Analyze the reasons for the Source-controlling and emission reduction techniqueswhich used during the "eleventh five-years" has played a positive role, Meanwhile thegovernment and enterprises to pay attention increasingly of reduction,also played apositive role. But also to control the source reduction ranked performance played acatalytic role. But the water environment status of Liao river source area remains aserious problem, the water quality urgent need to further improve, the main majorpollutants of COD and NH3-N emissions need to be further controlled. Finally, on thebasis of the conclusions analysis, made a number of recommendations on thesource-controlling and emission reduction of Liao river source area.
