　　一、處理工藝的差異

　　1、 Differences in processing techniques

　　活性炭滯留衰變工藝：在第三代核電站放射性廢氣處理系統中，活性炭滯留衰變工藝具有相對安全及占用空間小的突出優點。不同核電站的放射性廢氣處理工藝雖存在一定差異，但該工藝在第三代反應堆核電站的廣泛應用會產生較好的社會效益。

　　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.

　　化學洗滌 + UV 光解 + 活性炭吸附工藝：以杭州市第三固廢處置中心項目為例，根據廢氣成分和環保要求，選擇采用 “化學洗滌 + UV 光解 + 活性炭吸附” 的凈化系統工藝。該工藝對各個設備的工作原理、系統設置、風量計算、設備選型等進行了分析。

　　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 / 脫附 + 催化燃燒處理工藝：文章介紹了危廢處置中心暫存庫廢氣特點及常見處理工藝的優缺點，選用活性炭吸附 / 脫附 + 催化燃燒處理工藝對某一具體案例進行分析與探討。得出該組合工藝是危廢處置中心項目暫存庫有機物廢氣處理的一種新型工藝的結論，其性能穩定，成熟可靠，經濟環保，對于危廢行業有較好的應用前景。

　　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、空間利用及存儲容量的影響

　　2、 The impact of space utilization and storage capacity

　　在橡膠行業的 PT. Famili Raya 中，對有毒有害廢物的臨時存儲區域進行重新布局，采用 5S（Seiri、Seiton、Seiso、Seiketsu、Shitsuke）方法進行設計。結果表明，空間利用率降低了 32.67%，但并未減少廢舊電池、廢舊管狀燈、廢油和松節油廢物的最大存儲容量。

　　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、針對不同行業的特點

　　3、 Targeting the characteristics of different industries

　　多晶硅生產行業：為解決多晶硅生產中的廢氣處理問題，對原工藝進行了改革。改革后的工藝中，約 92.1% 的廢氣中的氯硅烷被回收，堿溶液的月平均消耗量減少了 500 噸。廢氣中有毒有害污染物的質量分數從 17.6% 降至 0.08%，完全消除了火災和爆炸事故，大大提高了系統的安全性和穩定性。此外，多晶硅產品的月平均產量和合格率分別提高了 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.

　　同位素生產線項目：為確保某同位素生產線項目產生的氣態放射性流出物能滿足排放標準，對比了加壓衰變法與滯留床吸附法的優缺點，提出了 “堿洗 + 冷凍除濕 + 吸附干燥 + 活性炭滯留” 聯合工藝。詳細介紹了處理工藝流程、主要設備的參數設計及滯留床活性炭用量的優化計算，對廢氣處理裝置的功能、系統流程、系統配置、布置方案等進行闡述。

　　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.

　　石油和天然氣行業：石油和天然氣行業中，柴油發動機的維護活動會產生 B3 廢物，即廢油。研究目的是基于文獻和 B3 臨時廢物存儲（TPS）的設計，確定石油和天然氣的危險廢物臨時存儲。通過描述性定性方法，參考政府法規，設計了 TPS，其中 B3 固體廢物倉庫的最大廢物容量為 4000 噸，B3 液體廢物倉庫的最大容量為 4000 升，B3 廢物 TPS 的建筑面積為 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
