Embodiment Construction

[0018] The following is a detailed description of the embodiments of the present invention. Neither these descriptions nor the drawings associated with these descriptions should be considered as limiting the invention.

[0019] A sludge bed filter separator 10 is provided. The mixed liquor suspended solids 12 (sludge) enters the separator 10 from the aeration zone 14 to the bottom 16 of the separator 10, and the mixed liquor suspended solids 12 are filtered from the sewage 18 through a filter material 20 consisting of flocculent suspended solids itself go out. Suspended solids 20 grow by agglomeration with other suspended solids or floes of suspended solids due to the vertical velocity lift force 22 . When the flocculated solids 20 become heavier than the vertical flow rate lift 22 (which gradually decreases with increasing cross-section of the separator), the flocculated solids 20 sink into the bottom 16 of the separator 10 and are then circulated to The anoxic zone 24 of ...

Abstract

The invention provides a circulating apparatus applied in the waste water treatment equipment, which uses the partial fluidized bed or combined fluidized bed filtering principle, and comprises a discrete channel for allowing sludge to flow between a separator bottom and an aeration zone, thereby improving other inherent low efficiency factors in the treatment system using the present cycle design.

Description

technical field [0001] The present invention relates to the disposal of municipal sewage and industrial liquid waste, and in particular to a compact activated sludge microbial treatment system comprising biochemical organic matter in continuously circulated wastewater in anoxic, aerated and fluidized bed filtration zones remove. Background technique [0002] Compact design bioreactors including anoxic reaction zone, aeration zone, fluidized bed filter sludge separation zone and activated circulating sludge system are usually used in wastewater treatment. They can be designed to remove carbonaceous organic matter, carbon removal and nitrification, denitrification, or carbon removal, nitrification, denitrification and phosphorus removal. For carbon removal, the anoxic zone is used as a "selective zone" to improve the settling performance of the mixed liquor And control the growth of filamentous bacteria. In order to remove nitrogen and phosphorus, the anoxic zone provides th...
