　　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(chǔ)容量的影響

　　2、 The impact of space utilization and storage capacity

　　在橡膠行業(yè)的 PT. Famili Raya 中，對(duì)有毒有害廢物的臨時(shí)存儲(chǔ)區(qū)域進(jìn)行重新布局，采用 5S（Seiri、Seiton、Seiso、Seiketsu、Shitsuke）方法進(jìn)行設(shè)計(jì)。結(jié)果表明，空間利用率降低了 32.67%，但并未減少?gòu)U舊電池、廢舊管狀燈、廢油和松節(jié)油廢物的最大存儲(chǔ)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(duì)不同行業(yè)的特點(diǎn)

　　3、 Targeting the characteristics of different industries

　　多晶硅生產(chǎn)行業(yè)：為解決多晶硅生產(chǎn)中的廢氣處理問(wèn)題，對(duì)原工藝進(jìn)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(zhì)量分?jǐn)?shù)從 17.6% 降至 0.08%，完全消除了火災(zāi)和爆炸事故，大大提高了系統(tǒng)的安全性和穩(wěn)定性。此外，多晶硅產(chǎn)品的月平均產(chǎn)量和合格率分別提高了 13.8% 和 4.7%。

　　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.
