The invention relates to a biological and ecological multiplication
reaction system. The biological and ecological multiplication
reaction system is composed of a pre-treatment device, an ecological multiplication reactor and a vertical type bio-film reactor, which are connected in sequence, wherein the ecological multiplication reactor is composed of a tank body, a
water flow driving device and an
algae harvesting mechanism; a
fluidized bed and alga, which are driven by the
water flow driving device to flow along with
sewage, are arranged in the tank body; the vertical type bio-film reactor comprises a shell, and an anaerobic region, an aerobic region, a reflowing region, a mud discharging region and a film
water production region which are arranged in the shell; an integrated separation layer is arranged at the peripheries of the anaerobic region and the aerobic region; an annular region between the separation layer and a
barrel body forms the reflowing region; a water outlet region is arranged at the top of the separation layer; a continuous or discontinuous
dielectrophoresis electrode DEP (
Diethyl Phthalate) film is arranged on an inner surface of the
barrel body corresponding to the position of the water outlet region along the
peripheral direction. According to the biological and ecological multiplication
reaction system, the
sewage is subjected to dual purification of the ecological multiplication reactor and the vertical type bio-film reactor; the biological and ecological multiplication reaction
system has the advantages of enhancing removal effects of
pollution substances including BOD (
Biochemical Oxygen Demand), TN (
Total Nitrogen), TP (
Total Phosphorus) and the like, saving energy and reducing consumption and occupying a small area.
