【摘要】：隨著工業(yè)的快速發(fā)展,大氣污染問題越來越突出,工業(yè)企業(yè)所排放的揮發(fā)性有機(jī)廢氣是造成大氣污染的重要來源之一。隨著工業(yè)廢氣的大量排放,大氣環(huán)境質(zhì)量逐漸惡化,給人們的生活帶來了諸多不利的影響,同時(shí)也給人們的健康帶來了危害,加強(qiáng)VOCs的處理與凈化具有重要意義。電子產(chǎn)品制造行業(yè)揮發(fā)性有機(jī)污染物的特點(diǎn)是低濃度、大風(fēng)量,屬于比較難處理的廢氣,容易對(duì)周邊環(huán)境和人體健康產(chǎn)生不利影響。本論文通過對(duì)蘇州市電子產(chǎn)品制造相關(guān)企業(yè)進(jìn)行調(diào)研,了解VOCs氣體的危害,電子產(chǎn)品制造行業(yè)VOCs氣體性質(zhì)和產(chǎn)生的特點(diǎn),重點(diǎn)對(duì)電子產(chǎn)品制造行業(yè)噴涂廢氣進(jìn)行分析研究,針對(duì)性的提出電子產(chǎn)品制造行業(yè)VOCs處理對(duì)策,以便提高蘇州市電子產(chǎn)品制造行業(yè)VOCs的治理水平,保護(hù)蘇州市大氣環(huán)境,提高蘇州市人民的生活水平。通過查閱資料,搜集相關(guān)信息,了解VOCs的危害、目前VOCs處理技術(shù);調(diào)研蘇州市電子產(chǎn)品制造行業(yè)VOCs氣體的種類,組成,排放特點(diǎn)、處理的技術(shù)、運(yùn)行中存在的問題,在上述調(diào)研的基礎(chǔ)上,歸納總結(jié)適合電子產(chǎn)品制造行業(yè)的處理方法;針對(duì)性的提出蘇州市電子產(chǎn)品制造行業(yè)揮發(fā)性有機(jī)污染物處理對(duì)策。本論文通過對(duì)蘇州市60家電子產(chǎn)品制造行業(yè)中噴涂工序在生產(chǎn)過程中產(chǎn)生的揮發(fā)性有機(jī)污染物進(jìn)行調(diào)查研究,調(diào)查結(jié)果表明:目前噴涂工序中所使用的涂料主要有溶劑型涂料、水性涂料及UV涂料,其中溶劑型涂料在企業(yè)生產(chǎn)中所占的比例較大,使用的企業(yè)高達(dá)83.3%;企業(yè)所使用的原輔料主要有涂料、稀釋劑、清洗劑等,這些原輔料在使用過程中都會(huì)產(chǎn)生VOCs。針對(duì)噴涂工序在生產(chǎn)過程中產(chǎn)生的VOCs,參考國(guó)內(nèi)外相關(guān)資料防治,提出了源頭控制+末端治理相結(jié)合的措施對(duì)電子制造產(chǎn)品產(chǎn)生的VOCs進(jìn)行防治。在源頭控制方面,使用粉末涂料、水性涂料、UV涂料、高固份涂料等清潔環(huán)保的原輔料,逐漸減少污染嚴(yán)重的溶劑型涂料的使用,從源頭上減少VOCs的產(chǎn)生;在末端治理方面,推薦使用處理效果相對(duì)較好的活性炭吸附法、活性炭吸附法+RCO、沸石吸附法+RTO等處理措施,并對(duì)以上三種工藝的原理、及工藝要求等提出了相關(guān)要求,然后結(jié)合現(xiàn)實(shí)情況,對(duì)活性炭吸附法和活性炭吸附+RCO的兩種處理方法建立了經(jīng)濟(jì)模型,以幫助電子產(chǎn)品制造企業(yè)選擇合適的處理工藝,在確保達(dá)標(biāo)排放的條件下,找出相對(duì)合適的投資費(fèi)用和運(yùn)行費(fèi)用,節(jié)省企業(yè)投資。最后為了確保以上意見和建議能夠?qū)嵤┎⑷〉靡欢ǖ男Ч?也從政府和企業(yè)的角度,對(duì)監(jiān)測(cè)監(jiān)管提出了相關(guān)要求。
[Abstract]:With the rapid development of industry, air pollution has become more and more prominent, volatile organic compounds emissions of industrial enterprises is an important source of air pollution. With a large number of industrial emissions, atmospheric environmental quality deterioration, brings many adverse effects to people's life, but also brings harm to people's health and it is of great significance to strengthen the management of VOCs and purification. The characteristics of the electronic product manufacturing industry of volatile organic pollutants is low concentration, large volume, difficult to deal with the waste gas is easy, the surrounding environment and human health have adverse effects. This paper through the research of Suzhou City electronic products manufacturing enterprises, understand the harm of VOCs gas the electronic product manufacturing industry, VOCs gas character and characteristics, focusing on the analysis of gas spraying in electronics manufacturing industry, aiming at The proposed VOCs industry solutions in manufacturing electronic products, in order to improve the level of management of Suzhou City electronics manufacturing industry VOCs, atmospheric environmental protection in Suzhou City, Suzhou City, improve the living standards of the people. Through access to information, collect relevant information, understand the risks of VOCs, VOCs processing technology the research of Suzhou city; types of electronic products manufacturing the industry of VOCs gas, emission characteristics, processing technology, the problems existed in the operation, based on the above research, summed up the methods for electronic product manufacturing industry; put forward the industry of volatile organic pollutants treatment in Suzhou manufacturing electronic products. This paper based on the investigation of volatile organic pollutants spraying the process in the production process of 60 electronic products manufacturing industry in Suzhou City, the survey results show that: the process of spraying used Coatings include solvent coatings, waterborne coatings and UV coating, the solvent coating in the production enterprises accounted for a larger proportion of the enterprise, using up to 83.3%; the business uses raw materials are mainly paint, thinners, cleaning agents, these raw materials will produce VOCs. for the coating process in the production process the VOCs is in use, a review of relevant information control, puts forward the source control + end treatment measures combining the electronic product manufacturing VOCs control. In the source control, the use of powder coatings, waterborne coatings, UV curable coatings, high solid coatings and other clean raw materials, gradually reduced the use of solvent based paint pollution, from the source to reduce the generation of VOCs; at the end of governance, the effect of using the treatment recommended relatively better activated carbon adsorption, activated carbon adsorption of +RCO zeolite +RTO and other treatment measures, and the principle of the above three kinds of process, put forward relevant requirements and technical requirements, and then combined with the reality of the situation, two methods of activated carbon adsorption and adsorption of activated carbon +RCO economic model is established, the process of choosing the right choice to help the electronic products manufacturing enterprises, in order to ensure the discharge conditions, find out the operating costs and investment costs relatively appropriate, save investment in enterprises. Finally, in order to ensure the above comments and suggestions to implement and achieve a certain effect, but also from the perspective of the government and enterprises, put forward relevant requirements of monitoring and supervision.
