The utility model relates to a novel bio-trickling VOCs (volatile organic compounds) waste gas removal device, in particular to the technical field of industrial waste gas treatment. The device comprises a bio-trickling filter, the bio-trickling filter comprises three trickling filter cavities, each trickling filter cavity is provided with a waste gas inlet, a gas outlet and a filler mounting port, the outer sides of the three trickling filter cavities are inwards connected with forward liquid inlet pipes, and the forward liquid inlet pipes are provided with spraying heads with downward spraying directions towards the interiors of the cavities. A reverse liquid inlet pipe is also arranged on the bio-trickling filter, is erected in the cavity and is provided with a reverse spray head with an upward spraying direction. The biological trickling filter overcomes the defect that the nutrient uptake of microorganisms in the middle layer and the lower layer is limited after the biological trickling filter is used fo
