The utility model discloses a
bacteria-
algae reactor and
treatment system, wherein the
bacteria-
algae reactor comprises a reactor cylinder body which is a transparent
glass structure, the reactor cylinder body is used for limiting a
sewage reaction area, a guide plate is installed in the
sewage reaction area and is fixedly connected with the reactor cylinder body, a plurality of light plates are arranged on the side wall of the reactor cylinder body, and the light plates are arranged on the side wall of the reactor cylinder body. In the axial direction of the reactor cylinder, the light plates are spirally distributed to form a light band
assembly. The application accidentally finds that the reactor is beneficial to efficiently and rapidly generating large-particle-size ABGS
sludge, the physicochemical property and decontamination effect of ABGS are superior to those of a conventional reactor, the reactor enables
algae to be fixed on AGS granular
sludge within 7 days,
granulation is completed within 20 days, the average particle size reaches 1.8 mm, and
sludge particles are more uniform, compact and stable.
