In 2015, the target task decomposition of air pollution prevention and control has been officially introduced. According to the “Environmental Air Quality Standards†(GB3095-2012), the number of days with good air quality in the main city is maintained at 240 days or more, and the heavy pollution weather is less than 18 days. The average annual concentration of PM2.5 decreased by more than 8% compared with 2013, and the annual average concentration of sulfur dioxide and nitrogen dioxide remained at the standard. To this end, in addition to continuing to implement dust pollution control, promotion of clean energy and environmental protection relocation, Chongqing Municipality will carry out pilot and promotion of vehicle exhaust gas remote sensing monitoring in the main urban area.
Heavy pollution in the main city is less than 18 days According to the 2015 air pollution prevention key work target task decomposition chart, in terms of air quality, the overall air quality in the main urban area is maintained at more than 240 days, and the heavy pollution weather is less than 18 days. The annual average concentration of PM2.5 in the air decreased by more than 8% compared with 2013, and the annual average concentration of sulfur dioxide and nitrogen dioxide remained at the standard.
Remote sensing and monitoring of tail gas in the main city It is reported that the number of motor vehicles in the main city of Chongqing is about 1.3 million, which is increasing at a rate of several hundred vehicles per day. Motor vehicle exhaust pollution has become one of the main sources of urban air quality hazards.
The relevant person in charge of the Motor Vehicle Exhaust Pollution Management Center revealed that the vehicle exhaust gas remote sensing monitoring pilot will be carried out and promoted, and 12 to 15 sets of motor vehicle exhaust gas telemetry inspection facilities will be installed in the main bridges and road gantry of the main city to explore the quality of oil products. Information management of source tracking.
The person in charge said that the vehicle exhaust gas telemetry system can be used to monitor the vehicles in the road while driving, so that the high-emission vehicles in the vehicle can be quickly found, without affecting the normal driving of the driver, causing no traffic jams, and automatically exempting the cleaning vehicles. Each monitoring point can detect thousands of vehicles a day, the efficiency is more than 10 times that of the traditional method, and the degree of pollution of the monitoring personnel will be greatly reduced, the labor intensity will be greatly reduced, and the working environment will be healthier and safer.
