The utility model discloses a CO2 injection flooding
produced water stripping treatment device which comprises a first reaction tank and a second reaction tank which are communicated with each other, a
flocculation flow separation tank, a steam stripping filler tank and a stirring overflow tank are sequentially arranged in the first reaction tank, a water inlet
pipe is arranged on the side wall of the first reaction tank, a dosing
pipe is arranged at the top of the first reaction tank, a flow guide
assembly is arranged in the
flocculation flow separation tank, a first filler bin is arranged in the steam stripping filler tank, and a first stirring
assembly is arranged in the stirring overflow tank; a
sludge discharge groove communicated with the stirring overflow tank is formed in the upper part of the side wall of the first reaction tank; the side wall of the second reaction tank is communicated with an air inlet
pipe and a water outlet pipe, a second filler bin and a third filler bin are sequentially arranged in the second reaction tank from bottom to top, and a second stirring
assembly is further arranged in the second reaction tank. According to the CO2 injection flooding
produced water stripping treatment device provided by the utility model, the two reaction tanks are arranged, so that the problem of gas waste caused by the fact that the N2 gas quantity of the existing device is not easy to control is solved.
