Embodiment
[0028] Rotating Biological Contactor (RBC) is a biofilm wastewater treatment technology with high microbial concentration, biological phase classification, strong impact load resistance, less sludge, good effluent quality, low power consumption, and maintenance management Convenient and other advantages, it is widely used in the treatment of low-concentration sewage such as domestic sewage. However, under normal circumstances, the biological turntable has low volume load, complex disk structure, high manufacturing and processing costs, heavy maintenance workload of the turntable drive device, and easy anaerobic fermentation of the biofilm on the disk to produce odor. Therefore, this technology needs further development. The present invention improves the traditional biological turntable by changing the disc into a tumbler cage structure, adding fillers in the tumbler as a carrier for biofilm attachment, so as to improve the mass transfer performance in the reactor and strengthe...
