活性炭在使用过程中会产生二次污染吗？如何避免？

答：正常使用情况下，合格活性炭不会产生二次污染，但吸附饱和后若处理不当，可能出现污染物脱附泄漏。

避免二次污染的方法：

及时更换或再生：当活性炭达到吸附饱和时，及时更换或再生，防止污染物脱附。

选择改性复合活性炭：如光催化复合活性炭，可将吸附的甲醛、VOCs 等污染物分解为 CO₂ 和 H₂O，从根本上避免二次污染。

规范处置废弃活性炭：工业废弃活性炭若吸附了有毒有害物质，需交由有资质的危废处理公司处置，不可随意丢弃；家用废弃活性炭可密封后作为普通垃圾处理。

Does activated carbon produce secondary pollution during use? How to avoid it?

Answer: Under normal usage conditions, qualified activated carbon does not cause secondary pollution. However, if improperly handled after reaching adsorption saturation, pollutants may desorb and leak.

Methods to prevent secondary pollution: Timely replacement or regeneration: When the activated carbon reaches adsorption saturation, it should be replaced or regenerated promptly to prevent pollutant desorption.

Opt for modified composite activated carbon, such as photocatalytic composite activated carbon, which can decompose adsorbed pollutants like formaldehyde and VOCs into CO₂ and H₂O, thereby preventing secondary pollution at its source.

Standardized disposal of spent activated carbon: Industrial spent activated carbon that has adsorbed toxic or hazardous substances must be disposed of by qualified hazardous waste treatment companies and should not be discarded indiscriminately; household spent activated carbon can be sealed and treated as general waste.
