Fenton fluidized bed for sewage treatment and method of fenton fluidized bed for sewage treatment

The invention discloses a fenton fluidized bed for sewage treatment. The fenton fluidized bed comprises a tower body, a water distributor, a water inlet pipeline, a circulating pipeline, a circulating water pump, charging pipelines and a drainage pipeline. The water distributor is arranged at the bottom end inside the tower body. The water inlet pipeline is communicated with the bottom of the tower body through the circulating water pump. One end of the circulating pipeline is connected to the upper portion of the tower body. The other end of the circulating pipeline and the water inlet pipeline are connected with a water inlet of the circulating water pump. The charging pipelines are located at the position, close to an inlet of the circulating pipeline, of the upper end of the tower body. The charging pipelines include the ferrous sulfate charging pipeline and the hydrogen peroxide charging pipeline. Supporter material silica sand is arranged in an inner cavity of the tower body. The fenton fluidized bed is reasonable in structural arrangement, silica sand is sufficiently suspended and dispersed into sewage to be processed in the tower body by selecting the proper length-diameter ratio of the tower body and the granularity and water distribution mode of supporter silica sand, and medicament is efficiently utilized and the cost is lowered by reasonably adjusting and controlling opening of a pipeline valve and automatically adding the medicament. The invention further discloses a method of the fenton fluidized bed for sewage treatment.
