Abstract

The invention provides a wastewater biological treatment system based on a bio-contact oxidation process, and belongs to the technical field of wastewater biological treatment. The biological wastewater treatment system includes a processing pool, a water inlet zone, a promote zone, an aeration zone and a slurry and water separation zone; the water inlet zone, the promote zone, the aeration zone and the slurry and water separation zone are integrally arranged in the processing pool, the aeration zone is configured to include a plurality of sub partitions, and a biomembrane filler is placed in each sub partition; two or more of the three of an anoxic zone, an anaerobic zone and an aerobic zone are arbitrarily combined to form the plurality of sub partitions. The biological wastewater treatment system has the advantages of good denitrification effect, high efficiency of sewage treatment, less sludge deposit, wide applicable range, and biological multiplication process.

Description

technical field [0001] The technical field of sewage biological treatment of the present invention relates to a sewage biological treatment system in which a water intake area, a lifting area, an aeration area and a mud-water separation area are integrated in a treatment pool, and in particular relates to an aeration area which is divided into multiple sub-areas and each sub-area Biofilm fillers are placed in the partitions to realize the sewage biological treatment system based on the biological contact oxidation process. Background technique [0002] Water resources are becoming more and more important in the development of society, and people are paying more and more attention to water treatment technology. Among them, sewage biological treatment technology has received extensive attention and has been continuously developed. [0003] A typical method in sewage biological treatment technology is the activated sludge method, which is based on the biological coagulation, a...
