At the end of the construction site, the dust is flying all over the sky, and Guangzhou moves to rectify it!
Jin Yang network reporter Liang Xuhao and correspondent Sui Huanxuan reported: The sky is dry and the things are dry, and the dust pollution is also coming. The monitoring data show that the average concentration of PM10 at Zhenlong National Control Point in Huangpu District of Guangzhou is the highest among the 10 national control points, and the increase is the largest. What caused the PM10 concentration at Zhenlong Monitoring Point to soar?
On the 13th, the reporter followed the law enforcement officers of Guangzhou Ecological Environment Bureau to visit several construction sites of Sino-Singapore Knowledge City near the monitoring point, and found that there were still cases where dust pollution prevention measures were not in place. During the construction of many construction sites, dust was flying all over the sky, and the fog gun dust remover was ineffective. In this regard, the municipal ecological environment department has taken measures to deal with it according to law.
At the end of the year, PM10 pollution intensified in the sprint construction site.
According to the research of the municipal ecological environment department, 58% of the sources of PM10 in Guangzhou are dust sources, and the proportion in the central city is as high as 68%. The lowest cost and fastest effective measure to reduce PM10 concentration is to effectively control dust pollution. However, at present, a large number of construction sites in the city have entered the sprint construction stage, and some construction sites still have the phenomenon that the "six 100%" requirements for dust pollution control have not been implemented, such as bare soil and no sprinkler spray, which has aggravated PM10 pollution.
The monitoring shows that from January to November, 2019, the average concentration of PM10 at Longguo Control Point in Huangpu Town, Guangzhou was the highest among the 10 national control points, with the largest increase. On December 1-10, the average concentration of PM10 at this point was about 1.2 times that of the other nine national control points.
At the intersection of Jiulong Avenue and Zhenlong Avenue, the construction is in full swing. A lot of loess has been excavated and piled up on the pavement or sidewalk. Some workers are burying huge drainage pipes underground, and some workers are operating cranes to plant trees in the pit. The reporter visually observed that the lot was at least carrying out greening and laying pipelines at the same time.
At the opposite position of the gas station at the intersection, several excavators were working intensively, and the loess was exposed and dusty. Mr. Zhong, the person in charge of the site, told the reporter: "This is the interchange project between Jiulong Avenue and Guangshan Road. It has been going on for several months, and now it will be finished soon. It will be completed by burying the drainage pipe, which is just these two days."
The dust on the construction site is flying, but the fog machine is a decoration
Construction goes on as scheduled, but how to prevent dust? The reporter found that a small gun fog machine was placed on a small open space opposite the construction site and on the road, but the wires of the machine had been buried in loess, and the machine was covered with thick dust and was not used at all.
When asked why there was a gun fog machine but it was not used, Mr. Zhong, the person in charge of the construction site, did not answer. Instead, he told the reporter: "We have sprinklers, but vehicles are walking around. First of all, we must ensure the sprinkling of roads. Moreover, water can’t be sprinkled too much, mud will affect the construction, and it will also be complained by surrounding residents. " After waiting for a few minutes at the construction site, I finally saw the figure of a small sprinkler, but the vehicle just drove near the construction site and suddenly turned around and left.
Then, the reporter and eco-environmental law enforcement officers came to the Unicom project site of Innovation Avenue in Knowledge City to face the road, and all the green belts in the middle of the road were dug up, exposing a lot of loess, which was completely uncovered; Moreover, there are many construction facilities piled up on the road, several workers are mixing sand and gravel in the open air, and many passing vehicles are also totally embarassed.
Focus on the supervision of construction sites and road dust, open burning, etc.
After the on-site investigation, the law enforcement officers of the ecological environment entered the problems of the above two construction sites into the law enforcement APP and handed them over to the relevant departments for processing.
The relevant person in charge of the Municipal Bureau of Ecology and Environment told the reporter that the dust on the construction site is different according to the nature of the construction site, and the regulatory authorities are also different, which makes supervision difficult. At present, the management of construction sites is relatively standardized, but linear sites such as roads and greening have the characteristics of long front and short construction time, and bare soil coverage is often not in place, which makes supervision more difficult.
In order to effectively cope with the polluted weather caused by drought and lack of rain, the Municipal Bureau of Ecology and Environment, together with relevant departments and districts, launched a campaign to tackle PM10 pollution. The Municipal Bureau of Ecology and Environment has formed eight action groups, focusing on the key points of PM10 prevention and control, and conducting uninterrupted inspections from 8: 00 to 24: 00 every day, focusing on the supervision of key pollution sources such as dust from construction sites and roads, open burning, catering fumes and industrial enterprise exhaust emissions in key areas.
According to reports, in the next step, the Municipal Bureau of Ecology and Environment plans to issue the "Intensive Plan for the Prevention and Control of Air Pollution in Winter and Spring of 2019-2020 in Guangzhou", by strengthening various regulatory measures such as industrial emission reduction, mobile sources and non-point sources, and at the same time supervising the implementation of enhanced measures, ensuring that all measures are implemented, doing a good job in dealing with polluted weather and ensuring air quality this winter and next spring, ensuring the completion of the annual air quality improvement objectives and tasks, and fully guarding "Guangzhou Blue"
Add some material to the news
The prevention and control of dust pollution is an important part of air environmental control, but this work involves many functional departments. Many citizens often don’t know which department to report to when they find illegal operation sites. The reporter sorted out this.
