【摘要】： 要想提高中國(guó)居民的整體室內(nèi)環(huán)境健康的素質(zhì),真正改善人們的家居環(huán)境,開發(fā)一套方便可行、益于推廣、速度快、低成本的“居室室內(nèi)甲醛濃度的預(yù)測(cè)系統(tǒng)”就成為了當(dāng)務(wù)之急。這正是進(jìn)行本課題研究的根本動(dòng)機(jī)。 但是人們對(duì)此問題沒有產(chǎn)生足夠的重視,只是等到已經(jīng)修建完成之后,亡羊捕牢,這樣又花費(fèi)了大量的金錢和時(shí)間,效果又不明顯,所以如果能夠開展在設(shè)計(jì)協(xié)調(diào)中對(duì)室內(nèi)空氣品質(zhì)的預(yù)測(cè),對(duì)各方都是有利的。 本文的研究思路為:重慶地區(qū)室內(nèi)裝修環(huán)境污染調(diào)查分析—對(duì)影響室內(nèi)主要污染物甲醛的濃度變化的因素進(jìn)行分析—利用統(tǒng)計(jì)學(xué)方法建立室內(nèi)主要污染物甲醛濃度的數(shù)學(xué)預(yù)測(cè)模型—整合通風(fēng)模型與甲醛預(yù)測(cè)模型,構(gòu)建室內(nèi)甲醛濃度預(yù)測(cè)系統(tǒng)內(nèi)核—利用C++ Builder軟件開發(fā)研究室內(nèi)甲醛濃度預(yù)測(cè)系統(tǒng)軟件—對(duì)軟件進(jìn)行評(píng)價(jià)提出不足之處和改進(jìn)意見。 本文監(jiān)測(cè)實(shí)際裝修工程施工期間和竣工后室內(nèi)甲醛濃度的變化情況,對(duì)40戶裝修住宅室內(nèi)空氣中污染物濃度的檢測(cè)結(jié)果顯示,甲醛的超標(biāo)率和超標(biāo)倍數(shù)最明顯,可見,甲醛是重慶城市住宅室內(nèi)空氣中最主要的污染物。而甲醛的長(zhǎng)期的主要污染源又是因?yàn)榘宀牡尼尫?因?yàn)槠渌廴驹串a(chǎn)生的危害在短期內(nèi)可以消除。通過對(duì)新裝修住宅,進(jìn)行裝修全過程中室內(nèi)甲醛濃度的跟蹤監(jiān)測(cè),對(duì)影響甲醛濃度變化的外部原因如溫濕度變化、通風(fēng)等因素進(jìn)行實(shí)驗(yàn)分析。 通過對(duì)大量的采集的數(shù)據(jù)的整合及結(jié)合前人的研究,作者利用統(tǒng)計(jì)學(xué)方法得出重慶市甲醛濃度預(yù)測(cè)模型: C = 0.527 Q (0.102T-1.103)(0.015D+0.175)/1.218+1.071N/G式中C——室內(nèi)空氣質(zhì)量甲醛濃度,mg/m3 T——室內(nèi)溫度,℃D——室內(nèi)空氣相對(duì)濕度,% Q——板材單位面積釋甲醛率,根據(jù)板材分類等級(jí)可知N——房間每小時(shí)換氣率,0.1～1.0次/h G——單位體積房間所使用板材的表面積板材表面積S/房間容積V) 通過將復(fù)雜的通風(fēng)模型進(jìn)行簡(jiǎn)化,將甲醛濃度預(yù)測(cè)模型與簡(jiǎn)化通風(fēng)模型進(jìn)行整合,建立了以通風(fēng)模型為最底層,室內(nèi)甲醛的模型為第二層,室內(nèi)空氣品質(zhì)等級(jí)評(píng)價(jià)方法、個(gè)人濃度暴露模型為上一層次的客觀評(píng)價(jià)的居室室內(nèi)空氣品質(zhì)的評(píng)價(jià)系統(tǒng)理論。
[Abstract]:In order to improve the overall indoor environment health quality of Chinese residents, truly improve people's home environment, develop a set of convenience and feasibility, benefit from promotion, and speed up. Low-cost "indoor formaldehyde concentration prediction system" has become a top priority. This is the fundamental motive for the study of this subject. However, people did not pay enough attention to the problem. They just waited until the construction had been completed and the sheep were killed, which cost a lot of money and time, and the effect was not obvious. So if we can predict the indoor air quality in design coordination, it will be beneficial to all parties. The research ideas of this paper are as follows: investigation and analysis of indoor decoration environmental pollution in Chongqing area: analysis of factors affecting the concentration of formaldehyde in the main indoor pollutants; use of statistical method to establish the concentration of formaldehyde in the main indoor pollutants The mathematical prediction model of degree-integrated ventilation model and formaldehyde prediction model, The kernel of the indoor formaldehyde concentration prediction system was constructed. The software was developed by C Builder software to evaluate the indoor formaldehyde concentration and put forward some suggestions for improvement. In this paper, the change of indoor formaldehyde concentration during and after the construction of the actual decoration project is monitored. The detection results of indoor air pollutant concentration in 40 decorated houses show that the exceeding standard rate and the exceeding multiple of formaldehyde are the most obvious. Formaldehyde is the most important pollutant in indoor air of Chongqing city residence. And the long-term main pollution source of formaldehyde is the release of plate, because the harm caused by other pollution sources can be eliminated in the short term. Through tracking and monitoring the indoor formaldehyde concentration in the whole process of decoration, the external reasons such as temperature and humidity change, ventilation and so on, which affect the change of formaldehyde concentration, are analyzed experimentally. Through the integration of a large number of collected data and combined with previous studies, The prediction model of formaldehyde concentration in Chongqing was obtained by statistical method: C = 0.527 Q (0.102T-1.103) (0.015D 0.175) / 1.218 1.071N/G. Mg/m3 T- indoor temperature, D-, relative humidity of indoor air, formaldehyde release rate per unit area of% Q- plate, according to the classification grade of plate, the rate of air exchange per hour in N- room is known. The surface area of the plate used in the room per unit volume, S-1 / volume V, is simplified by simplifying the complicated ventilation model. The prediction model of formaldehyde concentration is integrated with the simplified ventilation model, and the evaluation method of indoor air quality grade is established, which takes the ventilation model as the bottom layer and the indoor formaldehyde model as the second floor. The personal concentration exposure model is an objective evaluation system theory for indoor air quality.
