On October 26th, the staff drove the multiple-functional dust-suppression vehicle conducting dust-falling test in East Section of Yaodian Building in the urban area.

On that day, the first set of multiple-functional dust-suppression vehicle introduced by the municipal environmental protection bureau appeared in the urban street. Dust-suppression vehicle is commonly known as mist cannon vehicle. It uses vehicle-mounted sprayer to produce water mist, and suppresses the dust in the air through combination, absorption and settling of water mist. As for the multiple-functional dust-suppression vehicle introduced by our municipality this time, its maximum horizontal spraying length is 120 meters and vertical spraying height is 60 meters, and it can lower the PM 2.5 and PM 10 indicators within the operating area by 10% to 15%. Compared with common water-spraying vehicle, it saves water by 30% to 40%, while its dust-suppression effect is 4 to 5 times of that of the latter one. According to schedule, our municipality will introduce 5 such dust-suppression vehicles.
