摘要：以陕西省安康市某工业区水泥厂的环境空气质量控制为例,采用基于析因分析法的区间两阶段随机规划法(factorial analysis-interval two-stage stochastic programming method,FA-ITSP),在考虑环境约束的前提下,建立以工业大气环境质量达标和处理成本最低为目标的数学模型;依据水泥厂的环境治理数据、 行业排放标准以及环境空气质量标准,针对去除工业大气中的主要污染物SO₂、 NO_x和颗粒物的烟气治理过程,进行治理工艺组合优选、 处理成本分析和数学模型析因分析。结果表明:水泥厂烟气治理的最优工艺组合选择双碱法、 选择性非催化还原法、 选择性催化还原法、 电除尘法和袋式除尘法;在主要参数对数学模型输出的贡献方面, 低效率类治理工艺的贡献率是64.88%～77.88%, 高效率类治理工艺的贡献率是7.87%～16.22%,高、 低效率治理工艺组合交互效应的贡献率是0.003%～16.22%; 使用去除效率不同的工艺组合有助于经济效益和环境保护的双赢; 控制好水泥厂脱硝、 除尘系统中的不确定性, 可有利于实现处理成本最低。

Abstract：Taking the ambient air quality control of a cement factory in an industrial zone in Ankang, Shaanxi province as an example, an interval two-stage stochastic programming method based on factorial analysis(FA-ITSP) was adopted. Under the premise of considering environmental constraints, a mathematical model with the objective of achieving industrial atmospheric environmental quality and minimizing processing cost was established. According to the environmental treatment data of cement plant, industry emission standards and ambient air quality standards, the treatment technology combination optimization, processing cost analysis and mathematical model factorial analysis were carried out for the flue gas treatment technology of removing major pollutants SO₂, NO_x and particulate matter in the industrial atmosphere. The results show that the optimal process combination of flue gas treatment in cement plant is the double alkali method, selective non-catalytic reduction method, selective catalytic reduction method, electric dust removal method and bag dust removal method. In terms of the contribution of the main parameters to the output of the mathematical model, the contribution rate of low efficiency processing is 64.88%～77.88%, the contribution rate of high efficiency processing is 7.87%～16.22%, and the contribution rate of the interaction effect of the combi-nation of high and low efficiency processing is 0.003%～16.22%. Using a combination of processes with different removal efficiencies contributes to both economic benefits and environmental protection. Controlling the uncertainty in the denitration and dust removal system of cement plant can effectively help to achieve the lowest processing cost.

Keywords：factorial analysis method; interval two-stage stochastic programming method; regional environment; industrial atmosphere; treatment technology; processing cost
