Method of sewage treatment in a sequential batch reactor

摘要

The purpose of the notification is the treatment of the effluent, comprising the pre-treatment phase carried out once and the repeated cycle phase, the pre-treatment phase incorporating the sludge biomass and the slurry material of less than 0,2 mm, and both the pre-treatment and the cycle phase. includes filling with raw sewage, oxygen reaction,sedation,decontamination and rest phase. This is characterised by the fact that, at the preliminary stage, after the introduction into the reactor (1) of biomass in the form of a nozzle, the reactor (1) is filled with raw sewage and then the dust material is transferred to the reactor (1) in quantities from 1 to 5 kg/m3. The total volume of the reactor (1) in the oxygen reaction operation is aerated from the bottom, followed by the biomass sedimentation, after which the purified waste water is discharged from the reactor in the decontamination operation. The reactor content (1) is then left to rest and, in the cyclical phase, the raw sewage is transferred from the bottom to the reactor (1),and the reactor (1) in the oxygen reaction operation is aerated from the bottom, followed by the sedimentation of the biomass, after which it is discharged from the reactor (1) the effluents purified in the decontamination operation. The content of the reactor (1) is left to rest and the cyclical phase is repeated.
