Charcoal adsorption, as the most commonly used method for enterprise waste gas treatment and the most common method for handling high air volume and low concentration VOCs, plays a very important role in VOC control and emission reduction. However, in daily inspections, it was found that enterprises generally have problems such as long-term failure to replace activated carbon or failure to properly open facilities, severe dampness or damage to activated carbon, use of inferior carbon, and air leakage in the activated carbon box, resulting in the inability of adsorption devices to function effectively.

规范运维活性炭处理设施，不仅有助于企业废气达标排放，更有助于降低生产经营风险，避免被管理部门执法处罚。提醒各企业务必重视定期检查活性炭状态。发现活性炭孔隙堵塞或表面黏附，应要立即更换。

Standardizing the operation and maintenance of activated carbon treatment facilities not only helps enterprises meet the emission standards, but also helps to reduce production and operation risks and avoid being punished by management departments for law enforcement. Remind all businesses to pay attention to regularly checking the status of activated carbon. If the pores of activated carbon are blocked or the surface adheres, it should be replaced immediately.

更换下来的废活性炭属危险废物，应当密闭贮存，交由具备危废处置资质的企业依法进行处置。

The replaced waste activated carbon belongs to hazardous waste and should be stored in a sealed manner, and handed over to enterprises with hazardous waste disposal qualifications for disposal in accordance with the law.

活性炭吸附设备失效的5大常见原因：

Five common reasons for the failure of activated carbon adsorption equipment:

1.活性炭长时间未更换、发白

1. Activated carbon has not been replaced or turned white for a long time

2.活性炭附着颗粒物、油渍、水

2. Activated carbon adheres to particles, oil stains, and water

3.活性炭未完全装填

3. Activated carbon not fully loaded

4.废气温度超过50℃导致活性炭失活

4. Deactivation of activated carbon due to exhaust gas temperature exceeding 50 ℃

5.活性炭箱体漏风

5. Air leakage in the activated carbon box

二、企业应如何规范使用活性炭

2、 How Enterprises Should Standardize the Use of Activated Carbon

活性炭的不当维护可能会严重影响治污设施的处理效果，因此企业在使用活性炭治理废气时，需要注重规范意识，加强维护管理，并牢记活性炭的使用“三个要”：

Improper maintenance of activated carbon may seriously affect the treatment efficiency of pollution control facilities. Therefore, when using activated carbon for waste gas treatment, enterprises need to pay attention to standardization awareness, strengthen maintenance management, and bear in mind the "three essentials" of using activated carbon:

首先，企业要掌握活性炭的质量鉴别技巧。采用“一称、二看、三试”的简单方法，快速地评估活性炭的质量，筛选出符合要求的活性炭，并充分填充，以确保箱体不出现空隙。

Firstly, enterprises need to master the quality identification techniques of activated carbon. Using a simple method of "weighing, inspecting, and testing", quickly evaluate the quality of activated carbon, screen out qualified activated carbon, and fully fill it to ensure that there are no gaps in the box.

其次，通过记录活性炭的运营和维护信息，例如箱体规模、处理风量、更换活性炭填充量及其碘值，以及设施的运维和耗材更换情况，从而建立废气处理设施运维台账。

Secondly, by recording the operation and maintenance information of activated carbon, such as box size, processing air volume, replacement of activated carbon filling amount and its iodine value, as well as the operation and maintenance of the facility and the replacement of consumables, a waste gas treatment facility operation and maintenance ledger is established.

最后，企业要定期检查活性炭的状态。如果发现活性炭的孔隙堵塞、发白、破碎、潮湿等情况，应立即更换废旧活性炭。此外，废旧活性炭属于危险废品，应将其密封贮存，按照法律要求交由具备危废处置资质的企业处置。

Finally, enterprises should regularly check the status of activated carbon. If the pores of activated carbon are found to be blocked, white, broken, or damp, the waste activated carbon should be replaced immediately. In addition, waste activated carbon belongs to hazardous waste and should be sealed and stored, and disposed of by enterprises with hazardous waste disposal qualifications in accordance with legal requirements.

三、如何判断活性炭是否失灵

3、 How to determine whether activated carbon is malfunctioning

观察活性炭表面状态，查看孔隙是否堵塞、活性炭表面是否发白发霉、吸水吸油、破碎解体等“非正常状态”，出现以上现象，活性炭均属于失活。

Observe the surface state of activated carbon, check whether the pores are blocked, whether the surface of activated carbon is white and moldy, absorbs water and oil, breaks and disintegrates, and other "abnormal states". If the above phenomena occur, activated carbon belongs to deactivation.
