What are the countermeasures for Tianjin’s haze?
1. Key pollutant-discharging enterprises have initiated contingency plans, and some blast furnaces have completely suspended production
After Tianjin launched the Level III (yellow) heavy pollution weather warning, the city’s 100 key pollutant-discharging enterprises implemented the "Tianjin Heavy Pollution Prevention and Control Plan". "Pollution Weather Emergency Plan" requires that the total emissions of pollutants such as sulfur dioxide, smoke, and nitrogen oxides be reduced based on their respective characteristics. After the early warning was issued, Tianjin Iron and Steel Group launched a pollution reduction plan. It mainly adopted "circulating flow bed technology" for the blast furnaces used in production. This technology effectively desulfurized the sintering production, reducing the previous emissions per cubic meter of each blast furnace. 500 mg of sulfur dioxide dropped by 95%, making the emitted smoke particles reach 10 mg per cubic meter, which is far lower than the national standard of 40 mg per cubic meter.
2. No big brooms are needed for cleaning, and new cars must not be sprinkled with water or mud.
During the smog period in Tianjin, the Environmental Sanitation Bureau sent more than 30 sanitation workers to collect land from the Liulin area. The debris from the demolition project was covered, a special sprinkler truck was arranged to spray water and dust, and the surrounding area of the debris receiving site was tidied up. At the same time, the Yanshui Road near the demolition project has been controlled and monitored 24 hours a day to resolutely prevent environmental pollution such as litter dumping and construction debris. In order to prevent road dust, starting yesterday, it was stipulated that on the days when the "Tianjin Heavy Pollution Weather Emergency Plan" is implemented, sanitation workers are not allowed to use large brooms after 7:30 every day. 10 small battery-operated sweepers and 60 small battery-operated sweepers are dispatched every day. A small energy-saving vacuum cleaner truck patrolled the roads, and 12 large-scale sweepers were dispatched to work on the main roads to ensure that the roads were clean and pollution-free.
3. More than 60 vehicles will be added to the backbone lines, and the vehicles will be turned off when parked for a long time
The Municipal Public Transport Group has formulated the "Public Transport Group Emergency Plan for Heavy Air Pollution Day" in advance to ensure that Sufficient preparations, rapid emergency start, and sufficient transportation capacity guarantee provide a safe, convenient and comfortable riding environment for citizens traveling in heavy air pollution weather. With Tianjin's haze and air pollution causing congestion on the public's travel routes, the Municipal Public Transport Group immediately launched a plan, requiring its bus line operating companies and fleets to respond immediately, promptly organize additional transportation capacity, and implement the operation plan to target the city's passenger flow during yesterday's morning peak. The actual increase is about 20%. Yesterday, more than 60 vehicles were added to the backbone lines to increase the overall transport capacity and ensure citizens' travel.
4. The "flag-raising" ceremony was moved into the classroom and outdoor sports activities were canceled
Recently, Tianjin launched a Level III response to heavy pollution weather. Although Monday coincides with the "Flag Raising Day" for primary and secondary schools, due to the haze weather, most primary and secondary schools in Tianjin moved the "flag-raising ceremony" into the classrooms and canceled the "sunshine sports activities" for students.
Staff from the environmental protection department said that during the early warning period for heavy haze pollution in Tianjin, citizens should advocate a green and civilized lifestyle: try to travel by public transportation and reduce the number of cars on the road; park in a timely manner Turn off the engine and reduce the idling speed of the vehicle; try to avoid refueling of motor vehicles during the day.
