精萘作為重要的化工原料，在生產(chǎn)生活中廣泛應用，但使用后產(chǎn)生的廢棄物若處置不當，會對環(huán)境與人體健康造成威脅。這些帶有刺鼻氣味、具有可燃性與毒性的廢棄物，需遵循嚴格的科學流程處理，才能將危害降到最低。從收集存儲到最終處置，每個環(huán)節(jié)都暗藏技術要點。

　　As an important chemical raw material, refined naphthalene is widely used in production and daily life. However, if the waste generated after use is not disposed of properly, it can pose a threat to the environment and human health. These waste materials, which have a pungent odor, flammability, and toxicity, need to be processed according to strict scientific procedures in order to minimize their harm. From collection and storage to final disposal, there are hidden technical points at every stage.

　　一、分類收集：安全處置的第一步

　　1、 Classification Collection: The First Step in Safe Disposal

　　精萘廢棄物來源多樣，包括生產(chǎn)過程中的殘渣、過期產(chǎn)品以及沾染精萘的包裝材料等，收集時必須嚴格分類。固態(tài)的精萘殘渣應單獨存放于密閉的耐腐蝕容器中，避免與空氣長時間接觸氧化；液態(tài)廢棄物，如清洗設備產(chǎn)生的含萘廢液，則需用專門的防滲漏容器收集。沾染精萘的手套、抹布等雜物，也不能隨意丟棄，需與其他廢棄物分開，防止交叉污染。同時，所有收集容器都要清晰標注 “精萘廢棄物” 字樣，注明收集時間、成分等信息，便于后續(xù)處理。

　　The sources of refined naphthalene waste are diverse, including residues from the production process, expired products, and packaging materials contaminated with refined naphthalene. When collecting, strict classification must be carried out. Solid naphthalene residue should be stored separately in a sealed and corrosion-resistant container to avoid prolonged exposure to air for oxidation; Liquid waste, such as naphthalene containing waste liquid generated from cleaning equipment, needs to be collected in specialized leak proof containers. Gloves, cloths, and other debris contaminated with naphthalene should not be discarded at will and should be separated from other waste to prevent cross contamination. At the same time, all collection containers must be clearly labeled with the words "refined naphthalene waste", indicating the collection time, composition, and other information for subsequent processing.

　　二、專業(yè)存儲：防止泄漏的關鍵

　　2、 Professional storage: key to preventing leaks

　　收集后的精萘廢棄物需妥善存儲，等待專業(yè)處理。存儲場所應選擇陰涼、通風且遠離居民區(qū)、水源地的區(qū)域，地面需做防滲漏處理，鋪設耐腐蝕的防滲材料，如高密度聚乙烯膜，防止廢棄物泄漏污染土壤和地下水。存儲容器要擺放整齊，保持一定間距，避免相互碰撞破損。同時，存儲區(qū)域需設置明顯的警示標識，嚴禁明火與吸煙，配備消防器材和泄漏應急處理設備，如吸附棉、中和劑等。此外，存儲過程中要定期檢查容器的密封性與完整性，發(fā)現(xiàn)破損或泄漏跡象，立即采取補救措施。

　　The collected refined naphthalene waste should be stored properly and wait for professional treatment. The storage location should be chosen in a cool, ventilated area away from residential areas and water sources. The ground should be treated with anti-seepage measures, and corrosion-resistant anti-seepage materials such as high-density polyethylene film should be laid to prevent waste leakage and pollution of soil and groundwater. Storage containers should be neatly arranged with a certain distance to avoid collision and damage. At the same time, clear warning signs should be set up in the storage area, and open flames and smoking are strictly prohibited. Firefighting equipment and emergency response devices for leaks, such as absorbent cotton and neutralizing agents, should be equipped. In addition, the sealing and integrity of the container should be regularly checked during the storage process. If any signs of damage or leakage are found, remedial measures should be taken immediately.

　　三、合規(guī)運輸：全程監(jiān)管保安全

　　3、 Compliant transportation: full process supervision to ensure safety

　　精萘廢棄物屬于危險廢物，運輸環(huán)節(jié)必須嚴格遵循相關規(guī)定。應由具備危險廢物運輸資質(zhì)的專業(yè)單位負責運輸，使用專門的防泄漏、防揮發(fā)運輸車輛，車輛需安裝衛(wèi)星定位系統(tǒng)，便于全程監(jiān)管。運輸前，要辦理危險廢物轉(zhuǎn)移聯(lián)單，詳細記錄廢棄物的種類、數(shù)量、去向等信息，確?？勺匪?。運輸途中，駕駛員和押運員需經(jīng)過專業(yè)培訓，熟悉應急處理方法，避免發(fā)生交通事故或泄漏事件。一旦出現(xiàn)意外，需立即啟動應急預案，采取堵漏、吸附、隔離等措施，防止污染擴散。

　　Naphthalene waste belongs to hazardous waste, and the transportation process must strictly comply with relevant regulations. Professional units with hazardous waste transportation qualifications should be responsible for transportation, using specialized anti leakage and anti volatilization transport vehicles that are equipped with satellite positioning systems for full supervision. Before transportation, a hazardous waste transfer manifest must be processed, detailing the type, quantity, destination, and other information of the waste to ensure traceability. During transportation, drivers and escorts need to undergo professional training and be familiar with emergency response methods to avoid traffic accidents or leakage incidents. Once an accident occurs, the emergency plan should be immediately activated, and measures such as plugging, adsorption, and isolation should be taken to prevent the spread of pollution.

　　四、無害化處理：消除隱患的核心

　　4、 Harmless treatment: the core of eliminating hidden dangers

　　精萘廢棄物的處理需采用無害化方式，常見的有焚燒和化學處理。焚燒法是將精萘廢棄物送入專業(yè)的高溫焚燒爐中，在 1000℃以上的高溫下徹底分解，轉(zhuǎn)化為二氧化碳、水和少量灰燼，消除其毒性和可燃性。但焚燒過程中會產(chǎn)生含氮氧化物、二噁英等污染物的煙氣，需配備先進的尾氣處理裝置，通過脫硝、除塵、吸附等工藝凈化后達標排放?；瘜W處理法則是利用化學反應改變精萘的化學性質(zhì)，使其無害化。例如，通過氧化還原反應，將精萘轉(zhuǎn)化為無毒或低毒的化合物；或使用特殊的吸附劑，將精萘從廢棄物中分離出來，再進行后續(xù)處理。無論采用哪種方式，處理后的產(chǎn)物都需進行檢測，確保達到國家規(guī)定的排放標準。

　　The treatment of refined naphthalene waste requires harmless methods, commonly including incineration and chemical treatment. The incineration method involves sending refined naphthalene waste into a specialized high-temperature incinerator, where it is thoroughly decomposed at temperatures above 1000 ℃, converting into carbon dioxide, water, and a small amount of ash to eliminate its toxicity and flammability. However, during the incineration process, pollutants such as nitrogen oxides and dioxins are generated in the flue gas, which requires advanced tail gas treatment equipment. After purification through processes such as denitrification, dust removal, and adsorption, the emissions meet the standards. The chemical treatment method is to use chemical reactions to change the chemical properties of refined naphthalene, making it harmless. For example, through redox reactions, refined naphthalene can be converted into non-toxic or low toxicity compounds; Alternatively, special adsorbents can be used to separate refined naphthalene from waste for subsequent treatment. Regardless of the method used, the processed product must be tested to ensure compliance with the national emission standards.

　　五、循環(huán)利用：變廢為寶的新路徑

　　5、 Recycling: A New Path to Turning Waste into Treasure

　　在確保安全的前提下，部分精萘廢棄物可嘗試循環(huán)利用。例如，對于純度較高的固態(tài)精萘殘渣，經(jīng)過提純、精制等工藝處理后，可重新作為原料投入生產(chǎn)，實現(xiàn)資源的再利用。一些沾染精萘的包裝材料，若未受到嚴重污染，經(jīng)過清洗、消毒等處理后，也可重復使用或回收加工。但循環(huán)利用需建立在嚴格的質(zhì)量檢測和安全評估基礎上，確保不會對后續(xù)生產(chǎn)和環(huán)境造成影響。

　　On the premise of ensuring safety, some refined naphthalene waste can be attempted to be recycled. For example, for high-purity solid naphthalene residue, after purification, refining and other processes, it can be reused as raw material in production to achieve resource reuse. Some packaging materials contaminated with refined naphthalene can also be reused or recycled after cleaning, disinfection, and other treatments if they have not been severely contaminated. But recycling needs to be based on strict quality inspection and safety assessment to ensure that it will not have an impact on subsequent production and the environment.
