Based on the air pollutant emission inventory of Jinan in 2020, VOCs status and existing problems typical industries including chemical industry, industrial coating, printing, furniture manufacturing were investigated analyzed, two reduction scenarios designed to estimate potential according enterprise scales end-of-pipe treatment techniques. The results showed that emissions from large small industry(7947.92 t), coating(2383.29 printing(792.87 manufacturing(143.79 t). industry painting dominated by enterprises, accounting for 46.45% 50.89% emissions, whereas printing medium-sized 51.76% 42.37% respectively. was a single inefficient technique, utilization rate efficient techniques such as combustion combination only 7.46%. on-site investigation reported some incomplete source substitution, inadequate management fugitive unsuitable facilities. Therefore, had certain potential. Under scenarios, greatest potential, with rates 69.58%-84.99%, 26.98%-34.74%, 36.96%-59.74%, 8.55%-40.45%, Among four industries, enterprises greater average 70.00% 44.23%, scenario higher target, micro greatly increased, reaching 87.49% 79.65%, this study could provide scientific basis developing governance enterprises.
