The Hohhot municipal bureau of ecology and environment has implemented a data-driven environmental regulation model with multiple automatic monitoring platforms for pollution sources. 

This system enables 24-hour dynamic tracking of pollutant emissions and provides anomaly alerts. When abnormal data is detected, the system automatically triggers an alert and sends precise notifications to the environmental management terminal. Currently, all 177 key pollutant-discharging units in the city are included in the intelligent regulation system.

Through advanced treatment processes such as SCR catalytic reduction with precise ammonia injection for denitrification, electric bag dust collectors, and SPC desulfurization and dust removal integration, Inner Mongolia Jingneng Shengle Thermal Power Co maintains sulfur dioxide emissions at 28 mg/m³, nitrogen oxides at 33 mg/m³, and dust at approximately 3 mg/m³, all of which are below national emission standards.

Automatic monitoring equipment is installed at emission outlets, and all data is transmitted in real-time to the environmental department's monitoring platform via data collectors. Enterprises receive electronic supervision orders through the automatic monitoring platform for pollution sources. Regulatory departments verify the feedback from enterprises based on local management principles, while law enforcement investigates and addresses suspected violations. As of Nov 19, Hohhot has achieved 296 days of good air quality, with a compliance rate of 91.6 percent, and the average concentration of pollutants has decreased.
