The city carried out law enforcement inspection of pollution sources.

It is expected that the air quality will improve on the 5th.

It is very unpleasant to have severe pollution on weekends, but fortunately, since yesterday afternoon, with the improvement of diffusion conditions in surrounding areas and the increase of wind in the afternoon, the concentration of pollutants has dropped significantly. In order to cope with the heavy polluted weather, the city began to enforce the law on fixed sources and mobile sources continuously from yesterday.

According to the introduction of the Municipal Environmental Monitoring Center, since yesterday afternoon, with the improvement of the diffusion conditions in the surrounding areas affected by the middle cold zone, coupled with the increase of wind, the decrease of relative humidity and the increase of the height of the mixed layer in the afternoon, the concentration level of PM2.5 in this city has dropped significantly, and most areas reached an excellent level around 5 pm.

The municipal environmental monitoring center predicts that today, the city still maintains unfavorable meteorological conditions with weak air pressure. However, due to the decrease of initial concentration on the 2nd, the regional intermediate cooling center continued to move northward, and it is estimated that the air quality in this city is Grade 3 light pollution. On the 4th, it was controlled by low pressure system, and the diffusion conditions were unfavorable. It is estimated that the air quality is four levels of moderate pollution; On the 5th, due to the influence of precipitation and north wind, it is expected that there will be a significant improvement, and the air quality will turn better to Grade II. On the 6 th, the diffusion conditions of pollutants are favorable, and it is expected that the level 2 will be good.

In order to cope with the current pollution process, the city launched the law enforcement inspection of pollution prevention and control yesterday. Dongcheng District and Chaoyang District Environmental Protection Bureau carried out full-time law enforcement and inspected the construction sites within their jurisdiction, and found no environmental violations.

The Municipal Environmental Monitoring Corps inspected Beijing Hualian Printing Co., Ltd. in the Development Zone. The company installed two sets of plasma photooxidation catalysis and a set of activated carbon adsorption+catalytic combustion waste gas purification facilities, and they are in normal use. The disposal of hazardous wastes such as waste oil drums conforms to the specifications.

On the evening of September 2, the Municipal Motor Vehicle Emission Management Center carried out law enforcement in Beijing in Fangshan District.
