The invention discloses a novel pollution treatment device for waste gas. The novel pollution treatment device comprises a walking trolley body and an agitating barrel, wherein the agitating barrel isfixedly arranged on the left side of a top end surface of the walking trolley body; the right side of the top end surface of the walking trolley body is provided with a concave platform; the upper end surface of the concave platform is provided with an absorption barrel; a wall body of the interior of the walking trolley body is provided with a driving cavity; the bottom of the outer wall of theright side of the driving cavity is fixedly provided with a first driving motor; an end surface of the left side of the first driving motor is connected with a driving threaded rod in a power fit manner; the external surface of the driving threaded rod is connected with a guide slide block in a thread fit manner; the guide slide block is connected with the driving cavity in a slide fit manner; theupper part of the guide slide block is provided with a second driving motor in a left-right through embedment manner. The novel pollution treatment device has a simple structure and is convenient touse; a liquid medicine is uniformly prepared and mixed; the manual agitation is not needed; the health of a human body is protected; meanwhile, an absorption component is automatically lifted to effectively and sufficiently collect the waste gas; toxic and harmful substances in the waste gas are absorbed through the liquid medicine, and the pollution of the waste gas is reduced.
