Xi\’an launched a special rectification action for dust pollution, and environmental monitoring equipment was appreciated

On April 4, a Xi\'an Wenming.com reporter heard from the Xi\'an Ecological Environment Protection Committee office that Xi\'an will carry out a special rectification action on dust pollution and carry out cross-checks through the establishment of a special action group, take a series of measures such as suspending work and straightening the city\'s bare land and dusty construction site, firmly promote the prevention and control of dust pollution, protect the \"bright and clear sky\" and fight the battle to defend the blue sky.

Scope: full inspection of construction sites, two types of companies and manure transport

This special action for remediation of dust pollution is mainly aimed at various construction, excavation and demolition sites in the city, such as housing, urban (shack) renovation, municipal, transportation, water management and metros Enterprises (manufacturing companies of ready-mixed concrete and ready-mixed mortar), storage yards for construction waste, storage yards, storage yards for material, sand and gravel yards, manure transport, sand and gravel transport vehicles.

District (county) governments and development zone management committees carry out construction, excavation (demolition) construction sites, two kinds of enterprises, construction waste disposal Nachang, the country, county, county, township, and municipal road dust pollution problems are extensively investigated and rectified, and urban clean-ups and washes are conducted at least once a month.

Task : Reduce PM10 indicators

In terms of dust control, ourcity ​​to ensure that the monitoring of dust load on main and secondary arterial roads and main roads entering the city are stable and reach an excellent level.

Strengthen the dust control of manure trucks, promote efficient washing of the wheels, chassis and body of manure trucks, and keep them completely sealed while driving. surveillance, license plate recognition, satellite positioning and tracking are used to monitor the entire process of road dust.

Reinforcing hardening and greening of bare ground in urban public areas, temporary inactive building plots, both sides of urban roads and urban rivers. The mud should be covered with high standard. Strengthening the afforestation and paving of the bare ground on both sides of the national and provincial arterial roads within the jurisdiction. to the conditionTemporary parking areas for diesel trucks mobecome hardened.

In the field of construction site dust control, our city will continue to promote the construction of an online dust monitoring system. Establish a construction site and road dust monitoring system, install an online construction site dust monitoring system and video surveillance, and network with industry monitoring departments.

Strengthen the construction of construction waste disposal and transportation projects and the sophisticated control of dust in construction waste landfills. Strengthen the fine-meshed control of building dust on construction sites. Establish a dynamic management list, strengthen water sprinkling to suppress dust, increase the number of washes of working vehicles and machines, and prevent mud driving.

Strictly monitor the transport vehicles sensitive to dust, implement the closed transport requirements for transport vehiclesconstruction waste vehicles and sand and gravel transport vehicles, strictly standardize the management of transport vehicles, and prevent dumping during transportation Drip and dust problems.

Guided by the reduction of PM10 indicators, our city will establish a dynamic control mechanism, and the construction site will strictly implement the \"six hundred percent\". Stop work immediately for rectification; in addition to the influence of sand and dust weather, when the hourly PM10 concentration exceeds 150 μg/m3 for 3 consecutive hours, construction site activities exceeding the environmental quality monitoring value by more than 2.5 times are suspended.

Regarding dust control in material yards, materials in industries such as foundries, iron alloys, coking, cement, brick and tile, lime, refractories, and non-smelting of ferrous metals will be strictly controlled Fugitive emissions of storage, transport and production processes.

The construction of the dust suppression plant and the closed transformation of the material conveying system have been basically completed in the powder material storage depot and the large coal and ore storage depot. Open-air loading and unloading operations and dry material operations are strictly prohibited.

Strictly implement two kinds of dust suppression measures for enterprises, install video surveillance equipment and network with the ecological environmental department monitoring platform.

Action: Cross-check, correct immediately if a problem is found

In the comprehensive inspection phase, our city will set up a special action cross-inspection team to carry out cross-supervision and stubble-type inspection. ItThe cross-inspection team reports the identified problems to the inspected districts, provinces and development zones on a daily basis.

Increase the frequency of supervision, compare the work tasks, build a ledger of problems, check one by one, correct one by one, check and accept one by one , and cancel the number one by one. For construction sites and unexcavated (demolition) sites where no dust prevention and control measures have been taken, two types of enterprises, and construction waste dumps, will be ordered to repair and punished according to law.

Each district, province and developing area will set up a joint inspection team to investigate all sources of dust in the area Conduct comprehensive inspections one by one, and immediately correct and investigate the problems found and handle them strictly Combined with the continuous summarytting special rectification actions, draw conclusions from a single body to strengthen normalized oversight work and consolidate and preserve previous rectification results.

Environmental monitoring equipment is appreciated

Environmental monitoring equipment is a widely used dust monitoring in the market. The equipment supports PM2. 5+PM10+noise+temperature+humidity+wind speed+wind direction+wind force+atmospheric pressure+TSP and other 10 monitoring items, which can be adjusted and widely used in construction site projects, residential areas, commercial areas, road traffic, materials Online real-time air quality monitoring in storage rooms and other places The product supports multi-device pairing, wind and rain resistant LED dot matrix display, optional video surveillance, free connection to private government network , real-time control from mobile APP + computer cloud.
