In the case that there are other pollutants in the water, more bin bodies 11 can be added on the basis of three bin bodies 11 (used as an anaerobic tank, an anoxic tank, and an aerobic tank). The vertical pipes 13 cooperate with the connecting pipe 12 to be used as an aeration pipeline, which can be not used in an anaerobic or anoxic environment. The plurality of limit cards 14 cooperate with the cover plate 15 to seal the upper opening of the bin body 11 according to the user's needs, so as to meet the environmental requirements for water body purification.
