Abstract

The invention discloses a biological aerated filter reactor and a treatment method, and the reactor comprises a water control area which is arranged at the bottom of the reactor and is internally provided with a piston which transversely reciprocates, the piston drives sewage entering in two directions to upwards flow through the whole filter bed twice in a stroke of a complete cycle, and particles and suspended solids in the sewage are discharged out in time; the filter bed area comprises a plurality of bed layers and is arranged above the water control area, the plurality of bed layers are filled with filter materials with biological membranes, and the sewage flows in a broken line shape among the bed layers. According to the biological aerated filter reactor and the treatment method, the problem of energy consumption caused by backwashing of an existing biological aerated filter can be effectively solved, the water distribution uniformity of the filter can be enhanced, and the sewage treatment efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of sewage biological treatment, in particular to an aerated biological filter reactor and a treatment method. Background technique [0002] Aerated biological filter is a high-efficiency biofilm sewage treatment process that integrates biological oxidation, filtration and adsorption. Reclaimed water reuse, closed-circuit circulation of corporate sewage and "zero discharge". However, during the operation, as the suspended solids and solid particles in the sewage are continuously intercepted by the filter material, the head loss increases, and the filter needs to be backwashed, and the energy consumption of the reactor increases. Suspended solids or suspended solids) requirements are higher. At present, the biological filter mostly adopts upward flow, and the gas and water bring the solid material into the depth of the filter bed, so that the space filtration can be better used, thus prolonging the backwash ...
