發(fā)布時(shí)間：2018-10-12 14:43
【摘要】：當(dāng)前,在眾多使室內(nèi)空氣污染的揮發(fā)性有機(jī)氣體中,甲醛和苯系物污染是造成室內(nèi)污染的主要兩方面。近年來,人們對室內(nèi)甲醛的認(rèn)識(shí)越來越多,且越來越重視,而對苯系物污染則關(guān)注較少。因此迫切需要對室內(nèi)苯系物污染的來源、釋放規(guī)律、影響因素以及控制方案等進(jìn)行深入的研究。本文的研究思路為:室內(nèi)苯系物污染現(xiàn)狀分析——室內(nèi)苯系物釋放規(guī)律及其影響因素研究——室內(nèi)苯系物控制方法對比——室內(nèi)苯系物控制方案制定。本文首先運(yùn)用文獻(xiàn)法,對苯系物的性質(zhì)、危害、來源、釋放規(guī)律及控制方法等進(jìn)行整理歸納。針對石家莊市近兩年新裝修房屋室內(nèi)共100個(gè)苯系物數(shù)據(jù)進(jìn)行了統(tǒng)計(jì)和分析,并對部分房屋進(jìn)行了跟蹤檢測,得出石家莊市新裝修房屋室內(nèi)空氣中苯系物的釋放規(guī)律及影響因素。跟蹤檢測結(jié)果分析表明:1)在100個(gè)新裝修住宅樣品中,苯系物超標(biāo)接近二分之一,其中,甲苯、二甲苯的超標(biāo)率分別為14%、28%,苯超標(biāo)不是特別普遍,超標(biāo)率約為3%,但由于苯系物可造成人體極強(qiáng)的危害,依然應(yīng)對其引起重視;2)新裝修后房屋室內(nèi)空氣中的苯系物濃度隨時(shí)間的推移逐漸下降,由于其來源主要是涂敷在裝修材料表面的油漆和涂料,因此無長期釋放性,一般3個(gè)月即可釋放完全;3)隨著溫度的升高,苯及苯系物的釋放速率也逐漸增大,二者呈現(xiàn)出正相相關(guān)性;4)室內(nèi)裝飾材料負(fù)載量也是苯系物污染物散發(fā)速率的決定因素之一;5)加強(qiáng)空氣流通可以在一定程度上加快苯系物的釋放,但其作用只在一定程度上實(shí)現(xiàn),并不是流量越大越好;本文還通過個(gè)案法和實(shí)驗(yàn)對比法,提出針對石家莊市居民室內(nèi)裝修苯系物污染控制的方案:1)經(jīng)濟(jì)型:空氣流通法與綠色植物法聯(lián)合控制;2)效果型:空氣流通法、空氣凈化器、綠色植物法及活性炭吸附法聯(lián)合控制;3)普及型:空氣流通法、綠色植物法及活性炭吸附法聯(lián)合控制。
[Abstract]:At present, formaldehyde and benzenes are the two main sources of indoor pollution among the volatile organic gases which pollute indoor air. In recent years, more and more attention has been paid to indoor formaldehyde, while less attention has been paid to benzene pollution. Therefore, it is urgent to study the sources, release rules, influencing factors and control schemes of indoor benzene pollution. The research ideas of this paper are as follows: analysis of the present situation of indoor benzene series pollution, study on the release law of indoor benzene series and its influencing factors, comparison of indoor benzene series control methods and formulation of indoor benzene series control scheme. In this paper, the properties, hazards, sources, release rules and control methods of benzenes are summarized by means of literature. Based on the data of 100 benzene series in newly decorated houses in Shijiazhuang city in recent two years, the data of 100 benzene series in newly decorated houses were analyzed, and some houses were tracked and examined, and the release regularity and influencing factors of benzene series in indoor air of newly decorated houses in Shijiazhuang City were obtained. The results showed that: 1) in 100 newly decorated residential samples, the benzene series exceeded the standard by nearly 1/2, among which, the exceeding rates of toluene and xylene were 14% and 28%, respectively, and the benzene exceeding standard was not particularly common. The rate of exceeding the standard is about 3%, but the concentration of benzene series in the indoor air of the newly decorated houses decreases gradually with the passage of time, because the benzene series can cause great harm to the human body. Because its source is mainly paint and paint coated on the surface of decoration materials, it can be released completely in 3 months without long-term release. 3) with the increase of temperature, the release rate of benzene and benzene compounds increases gradually. 4) the loading amount of indoor decoration materials is also one of the determinants of pollutant emission rate of benzene series, 5) enhanced air circulation can accelerate the release of benzene series to a certain extent, but its effect is only realized to a certain extent. It is not that the greater the flow, the better; this paper also through the case method and experimental comparison method, This paper puts forward a scheme to control the pollution of benzene series in the indoor decoration of Shijiazhuang: 1) economical type: combined control of air circulation method and green plant method; 2) effect type: air circulation method, air purifier, Combined control of green plant method and activated carbon adsorption method; 3) popular type: combined control of air circulation method, green plant method and activated carbon adsorption method.
