Per the Chongqing Municipal People’s Government on October 22, the Chongqing-Sichuan 2026-2027 autumn-winter air pollution control meeting was held in Neijiang, Sichuan on October 20, attended by officials from the Ministry of Ecology and Environment’s air department, the environmental authorities of both regions, and eight neighboring cities. The assessment: a super El Nino event makes long, basin-wide smog episodes highly likely this winter, so both regions must offset adverse meteorology with more certain, structural emission cuts.
Stationary and mobile sources tightened together
Chongqing and Sichuan have already jointly issued emission standards for brick kilns and industrial furnaces, synchronized their heavy-pollution response plans, and made cement production curbs a standing cross-region mechanism; this is the third consecutive year of joint winter enforcement. This round calls for consolidating the three heavy-pollution response lists, running staggered emission cuts in key industries, strengthening mobile-source inspection and enforcement, and holding to a daily dispatch, weekly consultation, monthly review rhythm.
What this means for AIFILTECH customers
First, with production curbs stacked on top of tighter standards, cement, brick, and industrial-furnace operators need dust removal and denitration equipment that stays stable across a longer operating window — heat-resistant, condensation-tolerant filtration beats a low initial price over a full winter. Second, under China’s performance-grading scheme, plants with top-tier environmental ratings earn operational flexibility during pollution episodes; completing a high-temperature filtration retrofit before winter is effectively insurance for production continuity. Third, the basin’s damp, foggy winters are hard on filter media, so specify elements based on long-term service data in humid, sulfur-bearing flue gas rather than lab numbers.
AIFILTECH’s MULCERAFIL ceramic fiber filter tube high-temperature gas filters and ceramic filter tube dust collectors are built for cement kilns, brick kilns, and industrial furnaces, supporting pulse-jet cleaning and online high-temperature operation for retrofit upgrades.
