Abstract: Waste gas emission has many characteristics such as many outlets, high concentration, miscellaneous species and unstable emissions, and is the main source of air pollution. However, grassroots law enforcement teams generally have problems such as fewer personnel, single inspection methods, and lack of supervision equipment, resulting in low efficiency of stationary source supervision. On the basis of analyzing the supervision effect of traditional law enforcement methods, a new supervision thought which pays more attention to regional supervision and on-site inspection, and implements intensive supervision to promote precise enforcement was put forward. An air-ground integrated, multi-dimensional supervision technical framework system for stationary source air pollutants emission was constructed, and a combination of high-resolution, high-flexibility technologies for different scenes was selected. A demonstration study on the applications of the technologies in the steel industry in Tianjin was carried out. The demonstration results showed that the regulatory technical framework system had good applicability, able to provide multi-scale and comprehensive pollutant emission data sets, and constitute a corporate compliance evaluation matrix, which could provide a strong guarantee for the implementation of accurate enforcement supervision. Limited to the current inconsistency of regulatory regulations and standards, the applications of new technologies need to be promoted by institutions at all levels.
