The invention is applicable to the field of sewage treatment, and provides a biochemical precipitation device for wastewater based on industrial sewage recycling. The biochemical precipitation device comprises an inlet, a treatment tank, a driving device, a treating device, an absorption device, and a transmission device. When the biochemical precipitation device is used, sewage is put into the treatment tank through the inlet at first, and at the moment, the driving device is started, and the driving device is composed of a positive and negative rotation motor; the driving device drives a rotating rod to rotate, the rotating rod drives a negative-pressure pump to rotate and generates negative pressure in a vacuum cavity, and at the moment, sewage at the top of a biochemical reactor can pass through the biochemical reactor in an accelerated manner under the negative pressure action of the vacuum cavity, so accelerated treatment of the sewage by the treatment device is realized; and when the sewage treated in the first step flows into a treatment tank II, the rotating shaft rotates under the transmission of the transmission device, and when the rotating shaft rotates, a biochemical component reciprocates on the surface of a screw rod and reciprocates in the sewage, so the accelerated purification treatment of the sewage is realized.
