“十一五”我国主要工业行业SO2和COD技术减排的效应分析

在分析＂十一五＂期间SO2和COD减排情况的基础上,通过构建体现分行业污染减排的环境效应分解模型,对各主要行业不同减排途径带来的污染技术减排效应进行测算,得到了各行业不同减排途径产生的技术减排效应值以及各行业污染技术减排的贡献度。测算结果显示,＂十一五＂期间火电、钢铁和水泥行业的SO2技术减排效应分别为2080万t、180万t、318万t,其中烟气脱硫工程在工业SO2污染减排中担负了主要贡献作用,贡献率为50.46%,造纸业、化学原料及制品行业、农副食品加工业的COD技术减排效应分别为309万t、103万t、135万t,最终给出了我国主要工业部门的SO2和COD技术减排效应对总减排效应的贡献度,分别为66.05%、51.10%,表明技术减排是＂十一五＂期间顺利实现污染减排的重要保证。

Technical Abatement Effect of SO_2 and COD in Main Industries in China during the Eleventh Five-Year-Plan Period

Based on the analysis of the reduction of sulfur dioxide（SO2） and chemical oxygen demand（COD） during the eleventh five-year-plan period,an environmental effective decomposition model was built to calculate the technical effect on emission reduction in the environment across various industries.The results showed the values of different technical reduction as well as the contribution of various industrial sectors to pollution abatement.The results showed that the technical abatement effects of SO2during the eleventh five-year-plan period in thermal power industry,iron and steel industry and cement industry were 2080,180 and 318 million tons,respectively.Among which,the flue gas desulfurization project played a significant role and contributed to 50.46% of SO2 pollution reduction.The technical abatement effect of COD reduction in paper industry,chemical raw material and product industry,and agricultural and sideline product processing industry were 309,103 and 135 million tons,respectively.This study finally showed that technical abatement effects on SO2 and COD reduction in major industrial sectors contribute to 66.05% and 51.10% of the total.It was clear that the emission reduction technology was a significant guarantee to the realization of pollution reduction during the eleventh five-year-plan period.
