The two organizations have recommended the promotion of Xiamen haze coating can absorb

In recent days, Xiamen will again "haze Volt " the. January 19 , Hongwen and lake two PM2.5 air quality monitoring sites appear slightly polluted ; January 20 , although a slight decrease in pollution levels , but still close to the light pollution. Lift the haze , most people are hated .

Reporters noted that in this year's two sessions in Xiamen , the Association submitted a proposal sectors "on the radical urban pollution , eliminate haze Suggestions " I hope the Government and the community to bring attention to the impact of haze and take practical initiatives governance haze , and gave Xiamen fresh air.

[ Situation ]

Last 92 days there is haze

Looking back on 2013 weather, "haze " has become the most frequently occurring words nationwide , flight delays , masks popular , appearing one after another , " fog" , and haze are related . Although Xiamen mountain and sea, but also not immune : one day every four days or so , there is haze days , about every six days , there is one day " folder fog haze ."Sellotape


Meteorological Department data show that in 2013 , haze Xiamen ( both have fog haze ) the number of days to 69 days , marking the highest value since meteorological records ; If you simply count haze ( haze only no fog ) for a few days , it is up to 92 days , also a new record.

Environmental protection department data also showed that in 2013 , Xiamen excellent air quality days for 84 days , good days for 257 days , the number of days up to 24 days of light pollution , the main air pollutants ozone , nitrogen dioxide, PM2.5 and PM10. Since entering in 2014 , just 20 days time , there are six days of mild pollution, the main pollutant PM2.5 and nitrogen dioxide.

[ Analysis ]

Increased external contamination

From the analysis of the data has been released , the first quarter of 2013 , particle pollution in Xiamen , 40% comes from vehicle exhaust emissions , 21% from industrial pollution , dust pollution from 21 percent , and the remaining 18% are mainly foreign contamination.

Although the analysis of the data has not yet figured out the whole year , but environmental experts say , roughly the proportion of various pollutants in particulate matter pollution there will be no big change , that is, motor vehicle exhaust , industrial pollution, dust pollution is Xiamen three main sources of particulate matter pollution. The particulate matter is a major component of smog , and therefore , these three sources are also a major source of pollution haze .

Since entering in 2013 , the public obviously felt haze Xiamen more serious than in previous years . Environmental experts told reporters , from monitoring the situation, in 2013 the haze increased, mainly because of increased external contamination , such as cold air southward northern haze was blown up in Xiamen . But since entering in 2014 , Xiamen local pollutants haze "contribution rate" is worse.

" An obvious phenomenon is that in 2013 , when the cold air , haze Xiamen on the crowds , but since entering in 2014 , has gone cold , but the haze still not scattered , indicating that local pollution aggravated . " environmental experts say.Washi tape


[ Proposal ]

Multi-pronged treatment haze

How haze governance , to make Xiamen restore fresh air ? Regard, the Association sectors gives a few suggestions in the proposal .

Recommendation 1 : Radical power plants and other industrial waste pollution. Industrial enterprises gas desulfurization and denitrification must be reached in order to clean emission standards efflux , the environmental protection department of key industrial enterprises in the exhaust efflux online monitoring , increasing the pressure on the legal and social supervision exhaust pollution efflux .

Recommendation 2 : eradicate traffic pollution . First, the strict emission standards for motor vehicles , eliminate excessive vehicle emissions. Second, increase financial subsidies for new energy vehicles and other zero-emission electric vehicles, public transport and special vehicles first to adopt new energy vehicles. We must also strengthen efforts to put public transportation , scientific and rational set lines, extended service hours , so that people consciously reduce the frequency of use of private cars .

Recommendation 3 : Radical dust pollution. Will focus on the construction site included monitoring air pollution control units , while , so that " bare land " green up .Masking tape


Recommendation 4: The application of new technologies and new materials , reduce haze effects and hazards. Vigorously promote green building , development and application of absorbable haze of green paint ; choose the most serious regional haze roads, laying trial may " smoking" walking trails - " photocatalysis " sidewalk.

[ Interpretation ]

One of the proposal 's author Qiu Xiaolong :

Magic paint decompose haze

In the proposal put forward by the Association sector , the application of new technologies and new materials to reduce the effects of haze and harm is a new idea.

So, is there to absorb haze "magic paint " mean ? Currently, the domestic market has such products.

One of the proposal 's author Qiu Xiaolong told reporters , also called photocatalysis photocatalyst is a nano-technology , can produce photo-generated electrons and photogenerated holes through photocatalysis, with a lot of energy , can be decomposed organic pollutants in the air ; air can also be formed by reaction of the water molecules form hydroxyl radicals , decompose pollutants.

"If photocatalytic emulsion to paint them, the paint will have the ability to break down pollutants ; If the photocatalyst is sprayed onto the paving stones on the road also has the ability to break down pollutants ," Qiu Xiaolong said, Dutch scientists have a sidewalk in the Netherlands photocatalytic experiments carried out on the year's results show a high photocatalytic decomposition rate of nitrogen oxides a year could be reduced by 45 %. The nitrogen oxide is a major component of smog .

邱晓龙said: "Now technology has made , the cost is not high , Xiamen can introduce these techniques , you can develop your own new technology in the future , high-tech treatment haze will become a trend . ."Wholesale masking tape
