In the first half of the year, several major manufacturing provinces jointly issued three unified ecological environment standards for ecological and green integrated development demonstration zones.

For example, the relevant person in charge of the Shanghai Municipal Bureau of Ecology and Environment introduced that these standards mainly involve technical specifications for navigation monitoring of volatile organic compounds, technical specifications for on-site monitoring of waste gas from fixed pollution sources, and laser fume extraction technical specifications for ambient air quality forecasting.

"Environmental standards are an important technical basis for environmental law enforcement and environmental monitoring," said Zhang Zhongwei, Deputy Director of the Executive Committee of the Yangtze River Delta Integration Demonstration Zone. These standards are currently important areas of ambient air monitoring and governance, and are closely related to the country's actual interests and the interests of the people. related.

Another example, the technical specifications for on-site monitoring of waste gas from fixed pollution sources include the monitoring of waste gas generated by boilers and industrial furnaces, organized and unorganized emissions in the industrial production process, and the monitoring of waste gas generated by life services such as oil fume in the catering industry; Quickly grasp the dynamic spatial distribution and pollution characteristics of volatile organic compounds in industrial parks, chemical industries and other industries.

Among them, it is pointed out that for enterprises that emit dust and exhaust gas, measures are issued to directly suspend business for rectification if they are found to have high pollution and heavy emissions.

In response to environmental protection requirements, many small and medium-sized enterprises are intentional but insufficient, and the expensive central dust removal and purification system costs hundreds of thousands or even millions. Ordinary companies can't even think about it. The existing ventilation system can only be modified to protect the workshop environment, but the dust and waste gas discharged from the outside will not still affect the surrounding environment, and the consequences will still fail to meet the requirements of the relevant departments.

The relevant departments have made the following safety requirements: the dust cleaning system has not been customized, and the dust accumulated on the job site has not been cleaned up in a timely manner", "no dust removal equipment has been installed in the dust workshop ", from the above two hidden dangers, it can be seen that there is neither dust removal equipment nor dust cleaning. Enterprises with the system must pay close attention to it. Such hidden dangers will lead to excessive dust concentration in the air, which will lead to the occurrence of flash explosion accidents. On the other hand, it will affect the normal operation of the staff and be prone to human accident injuries. There are vicious hidden dangers for these All enterprises will be closed for rectification of laser machine fume extractors .
