垃圾焚烧烟气中二（口恶）英控制技术的评估与筛选

采用模糊综合评价法与层次分析法（AHP）相结合,建立以环境、经济和技术为一级指标的3层综合评价指标体系,对初步筛选出的双布袋活性炭吸附技术、硫及硫化合物抑制技术和硫及硫化合物抑制技术+活性炭固定床反应器技术等10项垃圾焚烧烟气中二（口恶）英控制技术或技术组合进行了综合评估.结果表明,硫及硫化合物抑制技术+活性炭固定床反应器技术组合综合得分最高（0.4831）,为目前垃圾焚烧烟气中二（口恶）英最佳控制技术.鉴于目前我国部分农村生活垃圾焚烧炉烟气中二（口恶）英排放不达标的情况,建议分布于农村的小型垃圾焚烧炉优先考虑采用此技术组合.我国各地区的垃圾焚烧企业可根据本地的经济发展水平、企业规模、炉型和工艺等实际情况,采用本文建立的指标评价体系和评估方法进行控制技术评估,筛选出适合本企业的最佳二（口恶）英控制技术,以有效控制我国垃圾焚烧二（口恶）英排放.

Evaluation and Screening of Dioxin Control Technology in Waste Incineration Flue Gas

To determine the best control technology for dioxin in waste incineration flue gas, a three-level comprehensive evaluation index system with environment, economy, and technology as the first-level indexes was constructed. The fuzzy comprehensive evaluation method and the analytic hierarchy process (AHP) were used to evaluate ten dioxin pollution control technologies or technology groups including "double bag activated carbon adsorption technology," "sulfur and sulfide inhibition technology," and "sulfur and sulfide inhibition technology+activated carbon fixed bed reactor technology". The "sulfur and sulfur compound inhibition technology+activated carbon fixed bed technology" scored the highest, and thus is currently the best control technology for dioxin pollution in waste incineration exhaust gas. This technology is suitable for small rural waste incinerators to ensure that dioxin emissions meet the standards. Depending on the local economic development level, enterprise scale, furnace profile, and technological process, waste incineration enterprises in various regions of China can adopt this index evaluation system and method to evaluate the dioxin control technologies and select the best one suitable for the enterprise so that dioxin emissions in the waste incineration flue gas can be effectively controlled.
