Abstract

The invention discloses a biological rotating disc sheet capable of improving a biofilm culturing amount. The biological rotating disc sheet comprises a disc-shaped framework of a hollow-out structureand a net-shaped disc surface arranged on the disc-shaped framework. Three-dimensional elastic filler is fully distributed on the net-shaped disc face, and the disc-shaped framework is filled with polyurethane sponge filler. According to the biological rotating disc provided by the invention, the biofilm culturing rate of the disc sheet is increased, and the defects that the biofilm culturing amount of an anoxic layer is low, and a biofilm is not easy to be implanted, easy to agglomerate, not easy to be stripped and the like are effectively improved. According to the invention, different fillers are utilized to create a proper environment for aerobic bacteria and anaerobic bacteria on the same disc sheet, so that the growth of biological membranes of an aerobic layer and an anoxic layer is facilitated, the membrane forming rate is greatly improved, and biochemical organic pollutants in water are efficiently treated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biological turntable disk capable of increasing the film-hanging amount. Background technique [0002] Biological turntable technology is a kind of biofilm sewage treatment technology, and biological turntable is a device that uses biofilm method to treat sewage. Founded in the 1960s by the former Federal Republic of Germany, it was developed on the basis of biological filters. This process has the advantages of flexible system design, convenient installation, simple operation, reliable system, low operation and operation costs; no aeration is required, and There is no need for sludge return, which saves energy, and at the same time, a higher purification effect can be obtained in a shorter contact time. [0003] The disc is the main component of the biological turntable, and it is also a key factor affecting the processing efficiency of the turntable. The disc mater...
