Flowing filter bed reactor for treating high-COD and high-SS wastewater

The utility model provides a flowing filter bed reactor for treating high-COD (Chemical Oxygen Demand) and high-SS (Suspended Solid) wastewater. The flowing filter bed reactor comprises a tank body, a stirring structure and a water distribution structure, the tank body is provided with a tank cavity, a grating plate is arranged in the tank cavity, and the grating plate divides the tank cavity into a filler space filled with suspended filler and a water distribution space located below the filler space. A water inlet pipe communicated with the water distribution space and a water outlet pipe communicated with the filling space are arranged on the tank body. The stirring structure is arranged on the tank body and extends into the filler space so as to stir the suspended filler and the wastewater in the filler space. The water distribution structure is arranged in the water distribution space and is connected with the water inlet pipe, so that entering wastewater can be uniformly distributed. According to the fl
