Yesterday, the capital was once again dominated by haze, and the air quality fell into a severe level of pollution. Fortunately, the "scavenger" north wind immediately came to the rescue, will wipe out the haze. From today to Thursday, the city’s air quality will remain at an excellent level.
On March 1st, the "Beijing Air Pollution Prevention Ordinance" was formally implemented. The Municipal Environmental Protection Bureau designated the first week of each month as the environmental law enforcement week. In the first law enforcement week, the environmental protection department will focus on the operation of coal-fired boilers and on-line monitoring equipment for pollution sources.
Heavy pollution came and hurried to the blue sky on Saturday only lasted for one day. From the day before yesterday, the air quality of the capital began to decline. Yesterday, the grey color started a new week, and the pollution continued to deteriorate. In most areas, the visibility was less than 3 kilometers. The city’s air quality was in serious pollution. According to the data from the city environmental protection monitoring center at 16:00, PM2.5 concentrations in Chengliu District averaged 280 micrograms per cubic meter; in Changping and Yanqing, etc. in the northwest, PM2.5 concentration was approximately 252 micrograms per cubic meter; Tongzhou in the southeast , Daxing and other places, PM2.5 concentrations generally reach 215 micrograms per cubic meter; Fangshan, Mentougou and other places in the southwest, PM2.5 concentration as high as 298 micrograms per cubic meter; only the northeastern Miyun, Pinggu and other areas PM2.5 The concentration is relatively low, with an average of 164 micrograms per cubic meter.
Although the hazy days and then back to the carbine, but fortunately it came quickly too fast, with the debut of cold air, today's day, the city's air quality will jump to excellent levels. According to the meteorological department, the impact of the cold air on the capital will last for three days, which means that the city’s air quality will maintain an excellent level from today to Thursday, and citizens can enjoy the blue sky and fresh air.
In addition, this cold air, despite its strong influence, brought about a north-west wind of the 4th or 5th level, but the cooling is not obvious. The maximum temperature in the next three days is about 7°C to 8°C, and the minimum temperature is -3°C, which is relatively warm.
In the first week of each month, environmental law enforcement was accompanied by the official implementation of the Beijing Municipal Regulation on Prevention and Control of Atmospheric Pollution. The municipal environmental protection department launched the "Zero Operation" at 0:00 on the 1st of this month. Beijing Hongxianghong Thermal Power Co., Ltd. in Beiqijia Town, Changping District The boiler room was found to have exceeded six times the sulphur dioxide level and received the first fine. It was proposed to be fined 8,000 to 100,000 yuan, and was ordered to make corrections. If it did not, it would be doubled. It is reported that the "zero point of action" has inspected 617 units in the city, of which 25 have excessive emissions, 11 companies have unsanitary measures and other environmental violations. Next, the environmental protection department will interview the person in charge of the problem company and further deal with illegal activities.
Yesterday, it met with hazy days. The law enforcement officers of the Municipal Environmental Protection Supervision Team and the District and County Environmental Protection Bureau continued to go to various districts and counties to focus on the inspection of coal-fired boilers. The deputy head of the Municipal Environmental Protection Supervision Team, Xiangyang Xiang, told reporters that this week's inspections strengthened the law enforcement forces. Every day, 6 to 9 inspection teams dispatched, focusing on boilers, and inspecting the company’s pollution source online monitoring equipment to ensure its normal operation. Once a problem is found, the environmental protection department will be punished according to the regulations.
The Municipal Environmental Protection Bureau has designated the first week of each month as an environmental law enforcement week. In the first week of March, the city will continue to focus on various types of coal-fired boilers for emissions inspections, and severely investigate and solve problems in areas such as excessive discharge, improper operation of facilities, and automatic monitoring. From April to December, the monthly special law enforcement contents will be determined according to the public reports, seasonal characteristics, and outstanding air pollution problems found in routine law enforcement. Special rectifications will be carried out in one or two industries or fields.
Doubt Why "It's a good day but three"
Last week, the capital had just experienced a week-long heavy pollution and finally ended up with cold air. However, the weather was less than three days old and the haze came back again. Many citizens lamented that "Beijing is only three days away." Is this really a rule?
Meteorologists told the reporter that cold air generally has three forms of expression: the first type can be said to be menacing type, that is, the cold air goes faster and faster, the cold air goes away, the weather gradually warms up, and the atmospheric conditions become relatively stable , The pollutants began to accumulate again; the second type was diffusion type. This cold air was generally divided into many small stocks and continued to affect the capital in a continuous manner. In this case, no other pollutants accumulated, and the cold air was then affected. Therefore, good weather lasts for a long time. Another kind of problem is that the cold air is so weak that it will not be able to get on. This is like last week's seven-day haze situation. Heavy pollution continues because there is no cold air to visit. .
“In general, under the current pollution source conditions, the haze weather depends on the weather conditions, and the weather conditions are directly related to the cold air, but there is no regularity between them.†The short-term reason is the weather conditions, and the long-term reason is the source of pollution. Therefore, if the sources of pollution are very small and weak, then the meteorological conditions will no longer be good and severe haze will not occur.
The capital also encountered fog and sky boilers as the focus of environmental law enforcement spot checks
The rapid deterioration of the environmental climate is a phenomenon that has only emerged since human society entered the industrial society. Industrial energy consumption pollution is the cornerstone of the environment and climate. As the saying goes, it is the mastery of masters to beat the seven-inch snake and seize the “seven inches†of industrial energy pollution.
