[ Focus on Chemical Machinery and Equipment Network] The hot summer is on the rise, and the risk of ozone pollution is rising rapidly.
All parts of the country are already waiting, and the treatment of VOCs (volatile organic compounds) is the top priority
.

Chemical Machinery Network Hot Concern Chemical Machinery

For example, Shanxi launched the 2021 volatile organic compound navigation inspection, requiring the realization of ozone peak reduction, precise traceability, establishment of a closed-loop management mechanism of "discovering problems-handing over rectification-looking back at the inspection", and strictly implementing the navigation information "daily-weekly-monthly" Report-special report" system, and the closed-loop work of "problems found during inspections, transfer to office for rectification, follow-up inspection and supervision, and verification and evaluation of sales numbers"
.

For example, Henan has launched a special law enforcement action for enterprises in the volatile organic compound industry across the province, starting at the end of May and ending at the end of September
.
For petrochemical, chemical, industrial coating, packaging and printing, oil storage, transportation and sales, and other VOCs-related enterprises, 117 enterprises and 101 gas stations in the Jiyuan Demonstration Zone were comprehensively investigated
.

For example, Jinan, led by the Ecological Environment Bureau, and 12 departments including the Municipal Bureau of Industry and Information Technology and the Municipal Public Security Bureau jointly formed a VOCs (Volatile Organic Compounds) Comprehensive Remediation Working Group, which clarified 5 key tasks
.
It is required to focus on categorized policies, give full play to the guiding role of green government procurement, and form the greatest work force
.

It is worth noting that the Ministry of Ecology and Environment recently publicly solicited the "Notice on Accelerating the Resolution of Current Prominent Issues in the Treatment of Volatile Organic Compounds (Draft for Comment)" which officially ended on June 2
.
The consultation draft mentions:

Carrying out the key tasks and problem rectification of VOCs governance "look back", to be completed by the end of July
.

Carry out investigation and remediation for the current outstanding problems of VOCs emission, which will be completed by the end of August
.

From June to September, conduct a round of LDAR data quality inspection and sampling for all LDAR-related enterprises, and organize the implementation of VOCs exhaust gas collection, emission concentration, removal efficiency of treatment facilities, and oil storage depots, gas stations, and oil terminal oil and gas recovery facilities of key enterprises.
One round of inspection and sampling
.

Before the end of September, all central enterprises shall submit their local checklists and governance ledgers to the Ministry of Ecology and Environment; complete the installation and networking of automatic monitoring facilities for the main discharge outlets of key VOCs pollutants
.

Before the end of October, guide enterprises to basically complete the classification and rectification of exhaust gas bypass; for problems that really require a certain rectification cycle, the treatment will be completed at the latest during the next shutdown (work) inspection and maintenance period
.
In principle, other issues should be rectified before the end of the year
.

During the "Thirteenth Five-Year Plan" period, China's blue sky defense war focused on PM2.
5 indicators, and in the process, many cities' ozone pollution problems have gradually become prominent
.
In order to reverse the trend of rising ozone indicators, air pollution control has begun to form two main lines
.
In the new period of the "14th Five-Year Plan", VOCs, an important precursor common to PM2.
5 and ozone pollution, have received more attention
.

Due to the complex formation mechanism of VOCs, large fluctuations in composition, and governance is still in its infancy, to a certain extent, the urgency is more than that of PM2.

　　Especially in the summer when ozone pollution is high, the actions and measures for the treatment of VOCs are more intensive
.
The industry also analyzed that for a long period of time in the future, the prevention and control of VOCs will become one of the "protagonists" in the treatment of qi in China, and it will also be an important winner in the results of the "14th Five-Year Plan"
.

　　Data from the Second National Pollution Source Census has conducted tentative investigations on volatile organic compounds in some industries and fields, with emissions exceeding 10 million tons
.
The inspector of the Law Enforcement Bureau of the Ministry of Ecology and Environment once said frankly that the structural changes in the composition of air pollution are very obvious
.
In recent years, some clues can also be seen in the ecological environment bulletin
.

　　Therefore, experts also stated that China's air pollution prevention and control work is developing in depth, and with more refinement, ozone pollution control and VOCs control will definitely move to the forefront
.
China urgently needs to develop and improve new theories, new methods and new technologies for air pollution prevention and control, find out the bottom line, trace the source, and investigate facilities, and target the “big households” of VOCs emission, strengthen national and local technical assistance and supervision, and make up for the shortcomings of VOCs control.
