摘　　要：有机污染工业废盐是废盐中最常见、处理难度最大的一类可溶性固体废物,普遍具有废物和资源的双重属性,有机杂质的脱除是废盐实现资源化再生利用的关键。针对废盐热解-氧化脱除有机物的工艺参数优化问题,以有机物的去除率为评价指标,通过单因素实验探究热解温度、热解时间、氧化温度、氧化时间和空气流速对有机物去除率的影响,并利用Box-Behnken设计-响应面法(Box-Behnken Design-response Surface Methodology,BBD-RSM)对热解-氧化工艺参数进行优化。结果表明,影响有机物去除率的工艺参数重要性排序为氧化温度、热解温度、空气流速、氧化时间、热解时间。优化后的最佳工艺参数为热解温度255℃、热解时间59 min、氧化温度592℃、氧化时间45 min以及空气流速229 mL/min,对应有机物去除率为93.05%,与实验值91.96%相比,相对误差仅为1.17%。本研究为有机污染工业废盐的高值利用提供了有效途径,有助于解决我国化工行业资源循环利用体系中的关键问题,保障生态环境安全,并推动我国从化工大国向化工强国的转型。Organic pollution industrial waste salt is the most common and difficult-to-treat type of soluble solid waste among waste salts.It generally possesses the dual attributes of waste and resource.The removal of organic impurities is key to the realization of resource regeneration and reuse of waste salt.Focusing on the optimization of process parameters for the pyrolysis-oxidation removal of organics from waste salt,the removal rate of organics was used as an evaluation index.Single-factor experiments were conducted to explore the effects of pyrolysis temperature,pyrolysis time,oxidation temperature,oxidation time,and air flow rate on the removal rate of organics.Box-Behnken design-response surface methodology(BBD-RSM)was employed to optimize the pyrolysis-oxidation process parameters.The results indicated that the order of importance of the process parameters affecting the removal rate of organics was oxidation temperature,pyrolysis temperature,air flow rate,oxidation time,and pyrolysis time.The optimized process parameters were a pyrolysis temperature of 255℃,a pyrolysis time of 59 minutes,an oxidation temperature of 592℃,an oxidation time of 45 minutes,and an air flow rate of 229 mL/min,which corresponded to an organics removal rate of 93.05%.Compared to the experimental value of 91.96%,the relative error was only 1.17%.This provides an effective approach for the high-value utilization of organic pollution industrial waste salt,helps address key issues in the resource recycling system of China's chemical industry,ensures ecological environmental safety,and promotes the transformation of China from a major chemical country to a powerful chemical nation.
