Continuous flow treatment system based on multistage activated carbon

The utility model provides a continuous running water treatment system based on multistage activated carbon, which does not cause penetration of pollutants, can be regenerated without interrupting water treatment, and greatly improves the mass transfer efficiency of ozone in water. The device comprises an activated carbon adsorption tank, a first water inlet of the activated carbon adsorption tank is connected with a raw water tank through a valve, and a first water outlet of the activated carbon adsorption tank is connected with a purified water tank through a valve. Regenerated liquid outlets of the activated carbon adsorption tanks are connected with the ozone tail gas destroying device through valves, and a second water outlet of the previous activated carbon adsorption tank is connected with a second water inlet of the next activated carbon adsorption tank through a valve; the water outlet II of the last activated carbon adsorption tank is connected with the water inlet II of the first activated carbon a
