Description

Synergistic biological rotating disc

Technical Field

The utility model relates to a water treatment and breed technical field, in particular to increase biological rotating disc.

Background

With the development of economy, the increasingly serious problem of water pollution is widely regarded. Among them, the biological rotating disk (RBC) method has been widely used for treating sewage and wastewater for over 50 years as one of the biofilm processes. However, due to size limitations, the rotating biological disk method is only suitable for treating medium and small discharge amount of wastewater. When a large amount of wastewater is treated by the rotating discs in a multi-stage series manner, the occupied area is large, and the operation cost is increased, which is one of the main reasons for limiting the application development of the biological rotating discs.

There are many factors affecting the processing effect of the bio-disc, and among them, the disc material, i.e. the carrier of the bio-film, is the most critical factor, and its performance is directly related to the decontamination efficiency of the disc. The existing biological rotating disk mainly adopts corrugated plastic plates, glass steel plates and the like, and has the advantages of single disk shape, small specific surface area, poor film forming performance, low treatment efficiency and short service life. In recent years, many students have improved and researched the technology of the biological rotating disk aiming at the defects of the ordinary biological rotating disk, and the effect is improved to a certain extent, but the improvement is not great.

On the other hand, in the existing environment-friendly biological treatment, the oxygenation process of aquaculture is to aerate water by a high-pressure fan to increase dissolved oxygen in the water for biological strains to decompose organic matters, oxygen in air is contacted with the water in the form of bubbles, and the process of contacting with the dissolved oxygen is finished after the oxygen in the air rises to the water surface, at the moment, a large amount of oxygen in the air bubbles is not utilized and dissolved in the water, so that the efficiency and the oxygen utilization rate are not high relative to the power consumption of the fan. On the other hand, the bio-disc process often focuses on increasing the diameter and specific surface area of the disc to improve the processing efficiency, and the disc is usually rotated by a motor or pneumatically driven by air, but the two methods do not improve the stress condition of the disc unit in water. As the biofilm grows, the weight of the disc increases, requiring more power to be expended. Therefore, the oxygen dissolving efficiency of aeration, the stress of the rotary disc and the utilization mode of aeration residual gas need to be effectively improved.

Aiming at the defects that the aeration efficiency of a fan is not high, the residual air cannot be utilized and the biological rotating disk, the biological rotating disk of the utility model is improved differently from other traditional rotating disks. The novel biological rotating disc is used as a combined unit with other processes, the structure and the filler of the biological rotating disc are innovatively designed, the aeration residual air and the oxygen in the residual air are fully utilized, the aeration efficiency of the fan is improved through the alternate rotation of the water film on the surface of the filler of the rotating disc in water and air, the treatment capacity of the biological rotating disc is increased, the application mode of the biological rotating disc method is enriched, a novel thought is provided for solving the problem of wastewater treatment with large drainage, and an effective way is provided for improving the quality and increasing the efficiency of water treatment.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an increase biological rotating disc that operation is energy-conserving, and the management is simple feasible.

In order to solve the technical problem, the utility model discloses a technical scheme does:

the disc is arranged on the turntable body, the filler body is arranged between the disc and the disc, symmetrical arc-shaped partition plates are arranged on the disc, fillers are arranged between the disc and the disc, and the arc-shaped partition plates are arranged in a staggered mode.
