室内除醛治理后检测验收
Inspection and acceptance after indoor formaldehyde removal treatment
治理后的检测，一是要确认释放源的治理效果，二是要检测室内空气中的甲醛浓度，以便确认是否安全。因此，与治理前重点检测甲醛释放源不同，治理后的检测，室内环境是否安全才是检测的重点。
After treatment, the first is to confirm the treatment effect of the release source, and the second is to detect the formaldehyde concentration in the indoor air in order to confirm whether it is safe. Therefore, different from the key detection of formaldehyde emission source before treatment, the detection after treatment, whether the indoor environment is safe is the focus of detection.
使用强力除醛剂治理后，常常会出现释放源的甲醛浓度低于室内空间的甲醛浓度的结果。这一是说明产品效果明确，甲醛释放源的治理非常到位，另外也说明，室内可能还有没有治理到的甲醛释放源，需要我们进一步寻找、治理。
After using strong formaldehyde remover, the formaldehyde concentration of the release source is often lower than that of the indoor space. This is to show that the product effect is clear, and the treatment of formaldehyde emission source is in place. In addition, it also shows that there may be no indoor formaldehyde emission source to be treated, which needs to be further explored and treated.
此外，还有一种可能，就是治理后经过时间较短，吸附在墙体、顶棚当中属于二次污染的游离甲醛还没有完全释放完。因此，治理后的第二次检测，最好在5～7天之后进行。
In addition, there is a possibility that the free formaldehyde adsorbed on the wall and ceiling is not completely released after a short period of time. Therefore, the second detection after treatment should be carried out after 5-7 days.
