　　The exhaust gas treatment system in the hazardous waste temporary storage room has various application differences in different projects. The following will elaborate in detail from multiple aspects.

　　一、处理工艺的差异

　　1、 Differences in processing techniques

　　活性炭滞留衰变工艺：在第三代核电站放射性废气处理系统中，活性炭滞留衰变工艺具有相对安全及占用空间小的突出优点。不同核电站的放射性废气处理工艺虽存在一定差异，但该工艺在第三代反应堆核电站的广泛应用会产生较好的社会效益。

　　Activated carbon retention decay process: In the third-generation nuclear power plant radioactive waste gas treatment system, the activated carbon retention decay process has outstanding advantages of relative safety and small space occupation. Although there are certain differences in the radioactive waste gas treatment processes of different nuclear power plants, the widespread application of this process in third-generation reactor nuclear power plants will generate good social benefits.

　　化学洗涤 + UV 光解 + 活性炭吸附工艺：以杭州市第三固废处置中心项目为例，根据废气成分和环保要求，选择采用 “化学洗涤 + UV 光解 + 活性炭吸附” 的净化系统工艺。该工艺对各个设备的工作原理、系统设置、风量计算、设备选型等进行了分析。

　　Chemical washing+UV photolysis+activated carbon adsorption process: Taking the Hangzhou Third Solid Waste Disposal Center project as an example, based on the composition of exhaust gas and environmental requirements, the purification system process of "chemical washing+UV photolysis+activated carbon adsorption" is selected. This process analyzes the working principles, system settings, air volume calculation, and equipment selection of various equipment.

　　活性炭吸附 / 脱附 + 催化燃烧处理工艺：文章介绍了危废处置中心暂存库废气特点及常见处理工艺的优缺点，选用活性炭吸附 / 脱附 + 催化燃烧处理工艺对某一具体案例进行分析与探讨。得出该组合工艺是危废处置中心项目暂存库有机物废气处理的一种新型工艺的结论，其性能稳定，成熟可靠，经济环保，对于危废行业有较好的应用前景。

　　Activated carbon adsorption/desorption+catalytic combustion treatment process: This article introduces the characteristics of waste gas in the temporary storage of hazardous waste disposal centers and the advantages and disadvantages of common treatment processes. The activated carbon adsorption/desorption+catalytic combustion treatment process is selected to analyze and explore a specific case. The conclusion is that this combination process is a new type of process for the treatment of organic waste gas in the temporary storage warehouse of the hazardous waste disposal center project. Its performance is stable, mature, reliable, economical and environmentally friendly, and it has good application prospects for the hazardous waste industry.

　　二、空间利用及存储容量的影响

　　2、 The impact of space utilization and storage capacity

　　在橡胶行业的 PT. Famili Raya 中，对有毒有害废物的临时存储区域进行重新布局，采用 5S（Seiri、Seiton、Seiso、Seiketsu、Shitsuke）方法进行设计。结果表明，空间利用率降低了 32.67%，但并未减少废旧电池、废旧管状灯、废油和松节油废物的最大存储容量。

　　In PT. Familia Raya of the rubber industry, the temporary storage area for toxic and hazardous waste has been rearranged and designed using the 5S (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) method. The results showed that the space utilization rate decreased by 32.67%, but did not reduce the maximum storage capacity of waste batteries, waste tubular lamps, waste oil, and turpentine waste.

　　三、针对不同行业的特点

　　3、 Targeting the characteristics of different industries

　　多晶硅生产行业：为解决多晶硅生产中的废气处理问题，对原工艺进行了改革。改革后的工艺中，约 92.1% 的废气中的氯硅烷被回收，碱溶液的月平均消耗量减少了 500 吨。废气中有毒有害污染物的质量分数从 17.6% 降至 0.08%，完全消除了火灾和爆炸事故，大大提高了系统的安全性和稳定性。此外，多晶硅产品的月平均产量和合格率分别提高了 13.8% 和 4.7%。

　　Polycrystalline silicon production industry: In order to solve the problem of waste gas treatment in polycrystalline silicon production, the original process has been reformed. In the reformed process, about 92.1% of chlorosilane in the exhaust gas is recovered, and the monthly average consumption of alkali solution is reduced by 500 tons. The mass fraction of toxic and harmful pollutants in exhaust gas has been reduced from 17.6% to 0.08%, completely eliminating fire and explosion accidents and greatly improving the safety and stability of the system. In addition, the monthly average production and qualification rate of polycrystalline silicon products have increased by 13.8% and 4.7% respectively.

　　同位素生产线项目：为确保某同位素生产线项目产生的气态放射性流出物能满足排放标准，对比了加压衰变法与滞留床吸附法的优缺点，提出了 “碱洗 + 冷冻除湿 + 吸附干燥 + 活性炭滞留” 联合工艺。详细介绍了处理工艺流程、主要设备的参数设计及滞留床活性炭用量的优化计算，对废气处理装置的功能、系统流程、系统配置、布置方案等进行阐述。

　　Isotope production line project: In order to ensure that the gaseous radioactive effluent generated by a certain isotope production line project can meet the emission standards, the advantages and disadvantages of the pressure decay method and the retention bed adsorption method were compared, and a combined process of "alkali washing+freeze dehumidification+adsorption drying+activated carbon retention" was proposed. A detailed introduction was given to the treatment process flow, parameter design of main equipment, and optimization calculation of the amount of activated carbon used in the retention bed. The functions, system flow, system configuration, and layout plan of the exhaust gas treatment device were elaborated.

　　石油和天然气行业：石油和天然气行业中，柴油发动机的维护活动会产生 B3 废物，即废油。研究目的是基于文献和 B3 临时废物存储（TPS）的设计，确定石油和天然气的危险废物临时存储。通过描述性定性方法，参考政府法规，设计了 TPS，其中 B3 固体废物仓库的最大废物容量为 4000 吨，B3 液体废物仓库的最大容量为 4000 升，B3 废物 TPS 的建筑面积为 108 平方米

　　Oil and gas industry: In the oil and gas industry, maintenance activities of diesel engines generate B3 waste, also known as waste oil. The research objective is to determine the temporary storage of hazardous waste for oil and gas based on literature and the design of B3 Temporary Waste Storage (TPS). By using descriptive qualitative methods and referencing government regulations, TPS was designed, with a maximum waste capacity of 4000 tons for B3 solid waste warehouse and 4000 liters for B3 liquid waste warehouse. The building area of B3 waste TPS is 108 square meters
