摘要:针对国内环境技术评估以定性判断为主，缺乏综合评估方法的状况，通过设置节能减排先进适用技术指标体系、确定指标权重、构建评估因素集及其隶属函数等过程，建立基于层次分析和模糊综合评估的定性与定量方法相结合的造纸行业废纸脱墨工艺节能减排先进适用技术评估方法。应用该方法，在洗涤法脱墨技术、浮选法脱墨技术、浮选-洗涤法脱墨技术3项技术中，筛选出浮选法脱墨技术作为废纸制浆脱墨工艺重点推广的节能减排先进适用技术，其余两项技术中，洗涤法脱墨技术优于浮选-洗涤法脱墨技术。

Abstract:Currently, domestic environmental technologies evaluation methods are mainly based on experts’ qualitative estimate and lack of comprehensive evaluation methods. By setting an indicator system of energy conservation and emissions reduction, determining the indicator weight, and constructing the evaluation factors set and its membership function based on AHP and Fuzzy comprehensive evaluation, an evaluation method of advanced and available technologies for energy conservation and emissions reduction of deinking process was established. Using this evaluation method, flotation method can be picked out as an advanced and appropriate technology for energy conservation and emissions reduction of deinking process from three technologies including washing, flotation-washing, and flotation. This evaluation method provides a basic method for decision making on deinking technologies evaluation and selection.
