室内甲醛污染模型构建及其应用

摘要

The house decoration uses in each kind of plate and it often includes the massive formaldehyde. The formaldehyde release will cause the pollution to the indoor air. Also, it will cause the harm to the health. Specially, when the density of the formaldehyde in the room surpasses the national standard, the harm is serious especially. Therefore, a quota prediction and analysis to the density of the indoor air formaldehyde is extremely essential. Base on the existence form and the proliferation pattern of the formaldehyde in the room, the mass balancing relations, and the model that some scholars have proposed, the article proposed the model to predict the density of the indoor air formaldehyde. The model can be used to simulate the actual situation that the formaldehyde releases into the indoor air. The model can tell us the density of the formaldehyde in the room after a while, and it can also give us a suggestion about the safe density of the indoor air.%室内装修用到的各种板材中往往含有大量甲醛，甲醛的释放会对室内空气造成污染，对人体健康造成危害。特别当室内甲醛浓度超过国家标准时，这一损害现象尤为严重。因此对室内空气中的甲醛浓度做一个定量的预测和分析是十分必要的。本文根据甲醛在室内空气中的存在形式和扩散模式，按照质量平衡关系，结合国内一些学者对室内空气污染物浓度提出的模型，建立室内空气中甲醛浓度的预测模型，并利用该模型来模拟室内甲醛释放的实际情况，对一段时间后室内空气中甲醛浓度进行预测，给出关于室内空气质量安全评价的建议。
