In the past two days, the relevant functional departments of the Guiyang Economic Development Zone are working hard to promote the water quality improvement work of the Sanjiangkou section of the Mati River. The reason is that the overflow of sewage has affected the water quality of the river due to the clogging of sewage interception channels.
Unlike previous pollution problems discovered through manual inspections, this time it was the environmental big data platform that discovered water quality problems. Two weeks ago, the Guiyang Economic Development Zone Ecological Promotion Bureau passed the platform and found that the water quality of the Sanjiangkou section of the Mati River was abnormal. After the problem was found, the Economic Development Bureau of the Economic Development Zone immediately started the investigation process, organized relevant responsible units to rush to the scene to find the cause, and actively formulated a rectification plan to promote the rectification of the problem. The rectification work is expected to be completed this month.
"The environment is people's livelihood, the green hills are beautiful, and the blue sky is also happiness." In recent years, the Guiyang Economic Development Zone has firmly adhered to the two bottom lines of development and ecology, and has continuously promoted the construction of the ecological environment. In 2016, leveraging the "Dongfeng" of the development of big data, the Economic Development Zone started the construction of an environmental protection big data platform by purchasing third-party services.
Recently, the reporter found on the environmental big data platform that through the camera connected to the platform, you can see the site situation of river treatment in real time.
At present, through the "big data eye" of the environmental protection big data platform, the Economic Development Zone has realized real-time monitoring of the two rivers of Mati River and Chen Liang River. "Our probes installed in the river take samples every hour, and through monitoring and analysis, we can monitor the changes in water quality in real time. We check the changes in the platform data every day. Once we find problems, we will report back to the relevant functional departments in time to find the source of the problem and analyze the cause. "Tian Li, head of the Soil and Water Conservation Division of the Economic Development Bureau of the Economic Development Zone, said that since the environmental protection big data platform was put into use, the water quality of Chen Lianghe and Mati River has been stable in four categories for a long time and is within the prescribed standard range.
In addition to monitoring water quality, the environmental protection big data platform of the Economic Development Zone also realized the monitoring of air quality. At present, there are 8 cameras in the region, 4 of which are river monitoring points and the other 4 are atmospheric monitoring points. These cameras can be rotated 360 degrees to achieve dead angle-free monitoring.
"Since the launch of the environmental big data platform, scientific analysis, comprehensive management, and full-process monitoring of the atmosphere and water quality have been achieved, which has improved the level and efficiency of the ecological environment management in the region. At the same time, it can accurately locate and promptly advance problem processing to achieve problem traceability. And the process visualization. Not only that, the environmentally friendly big data platform also has a mobile terminal, and a mobile phone can publish tasks and implement them on the unit and individual heads, which improves the speed of problem handling. "Tian Li said.
With the help of the environmental protection big data platform, the ambient air quality in the economic development zone has improved significantly, and the air quality rate has increased from 73.7% in 2013 to 94.9% in 2018. In the first 10 months of this year, the excellent rate of ambient air quality in the Economic Development Zone rose to 97.6%, a year-on-year increase of 1.7 percentage points.
At the same time, the region's energy conservation and emission reduction effect is obvious, the unit industrial added value solid waste production volume decreased by 30%, the unit industrial added value wastewater production volume decreased by 84%, the unit industrial added value nitrogen oxide emissions decreased by 75%; the concentration of major pollutants Compared with the same period last year, it showed a downward trend. Among them, the concentrations of PM10, PM2.5, SO2, NO2, and CO all significantly decreased.
"The problem facing the environmental big data platform is that the lack of data analysis can not help us to find an effective solution in a timely manner." Tian Li said that in the second phase of the construction of the platform, the Economic Development Zone will continue to upgrade the platform functions to solve the existing problems. Bottlenecks and pain points, truly realize the high-efficiency, high-level, high-quality services of big data for ecological environmental protection.
