The invention belongs to the field of waste gas recycling and environment-protection treatment devices, and particularly discloses a tank-washing-waste-gas recycling treatment technology. As the special processes of steaming, fresh water washing and hot air drying are adopted, generated waste gas has the characteristics of high temperature, large volatile matter concentration fluctuation, intermittent exhausting and the like; the new processes of normal-temperature water cooling, low-temperature water condensing and active-carbon secondary adsorption are adopted, the temperature of the high-concentration waste gas is reduced to be about 6 DEG C, organic matter in the waste gas is greatly condensed to be in the liquid state, the concentration of the gaseous-phase waste gas is greatly reduced, and then the low-temperature and low-concentration waste gas enters an active-carbon adsorption tank for adsorption. In order to guarantee that the concentration of the exhausted tail gas is reduced to be quite low and co
