Advanced wastewater treatment process using up and down aerobic - anaerobic reactors of channel type.

摘要

The present invention relates to the process for advanced wastewater treatmentusing up & down aerobic • anaerobic reactors of channel type in thesingle reaction tank in which it has the effluent recycle of channel type aerationreactor (internal cycle). For this, the anaerobic reactor of channel type isunder the aerobic reactor of channel type in the single reaction tank. And theflow of the wastewater in the single reaction tank is based on the water level differencebetween inlet and outlet, and the air lift effect of the air diffusers. The partitionsof channel type anaerobic reactor and the partitions of channel type aerobicreactor are cross. Consequently, the energy cost is cut down because the wastewaterflow does not need much pumping energy. And the site need is reduced because ofup & down aerobic • anaerobic reactors of channel type in the singlereaction tank.
