Biochemical reactor

The utility model discloses a biochemical reactor which comprises a biochemical reaction structure which comprises an anaerobic reaction zone, an anoxic reaction zone and an aerobic reaction zone; wherein a part or all of the anaerobic reaction zone and a part or all of the anoxic reaction zone are distributed below the aerobic reaction zone, are arranged on the same layer and are oppositely arranged. In the biochemical reactor, a part or all of the anaerobic reaction area and a part or all of the anoxic reaction area are distributed below the aerobic reaction area, are arranged on the same layer and are oppositely arranged, so that the integration level is further improved, and the construction period and the building material input cost can be remarkably reduced. 本实用新型公开了生化反应器，包括：生化反应结构，所述生化反应结构包括包括厌氧反应区、缺氧反应区和好氧反应区；其中，所述厌氧反应区的部分或全部区域和所述缺氧反应区的部分或全部区域分布于好氧反应区的下方且同层、相对设置。在该生化反应器中，通过使厌氧反应区的部分或全部区域和所述缺氧反应区的部分或全部区域分布于好氧反应区的下方且同层、相对设置，不仅集成度进一步得到提升，而且能够显著减少建设周期和建材投入成本。
