Hefei Economic and Technological Development Zone(HETDZ) was promoted to a NETDZ in 2000 and joined GPIP in 2016，representing the largest manufacturing base for refrigerators, forklifts, excavators, tires and hydraulic machines, as well as the largest production base for laptops. In terms of environmental management, HETDZ makes full use of intelligent technology to strengthen the overall control of river, lake and pipe networks by adopting intelligent environmental inspection modes such as river patrol by UAV and underground pipe network inspection by CCTV robots. Besides, in order to ensure the health and safety of residents in the area, HETDZ applied the relevant functions of the intelligent management system to epidemic prevention and control, focusing on strict management of sewage at the quarantine area, effectively preventing the spread of the virus.
