Abstract: A system and method for regulating and absorbing TFT-LCD organic solvent waste liquid in countercurrent are provided. In the system, each of longitudinal offset pipes of absorbing pipes is disposed between a lower filter plate and an upper filter plate, bottom positions of the longitudinal offset pipes are connected with a sinking-recovery pipe, each longitudinal offset pipe is provided with a photoelectric detector, an activated carbon supply pipe is provided with an activated carbon supply device, the sinking-recovery pipe is connected with a solid-liquid separator, and a wet activated carbon conduction mechanism is provided with a heating-separating device. Activated carbon particles in the absorbing pipe with a certain saturation amount are led out in a non-disassembly-replacement method, the saturated activated carbon is subjected to solid-liquid separating and heating degassing, thus the saturated organic solvent is separated and recovered and the activated carbon particles are recycled.
