Technical Field

The utility model belongs to the technical field of wastewater recovery, and in particular relates to a circular sedimentation tank for recovering wastewater from a large-scale pig farm.

Background Art

With the continuous improvement of economic level, the pig farming industry has also developed greatly. In the process of pig farming, a large amount of wastewater will be generated. This wastewater is a high-concentration organic wastewater with a very high nitrogen content and an imbalanced carbon-nitrogen ratio. It is very difficult to treat. When treating this wastewater, a wastewater recovery circular sedimentation tank is required.

The patent specification with the announcement number CN203803161U discloses a large-scale pig farm wastewater recovery annular sedimentation tank, which contains an inner annular pool and an outer annular pool, wherein the inner annular pool is arranged in the inner cavity of the outer annular pool, and a connecting hole is arranged at the upper end of the pool wall of the inner annular pool, so that the inner annular pool is connected with the outer annular pool, and a partition is arranged between the outer wall of the inner annular pool and the inner wall of the outer annular pool, and the partition divides the annular inner cavity between the outer annular pool and the inner annular pool into different cavities, and a through hole is arranged on the partition, and a liquid inlet pipe is arranged at the upper end of the inner annular pool, and a liquid discharge pipe is arranged at the upper part of the outer annular pool. Multiple rows and columns of through holes are arranged on each of the partitions, and the heights of the through holes on adjacent partitions are different according to the direction of liquid flow, and the heights of the through holes are arranged in ascending order. The utility model allows sewage to flow along the tangential direction of the circle, and then flows in a circular manner in different cavities through the through holes of the partition, thereby increasing the flow distance and improving the sedimentation effect. However, this wastewater recovery annular sedimentation tank has the following shortcomings when in use:

1. When the pig farm wastewater recycling annular sedimentation tank is in use, its partition needs to be cleaned and replaced when it is blocked. It is not convenient to disassemble it quickly, resulting in low efficiency of cleaning and replacement, affecting its use effect;

2. The pig farm wastewater recycling annular sedimentation tank is not convenient for cleaning the residues on the inner wall of the inner ring pool discharge pipe. The residues accumulate on the inner wall of the discharge pipe for a long time, which can easily cause blockage and affect the discharge efficiency. Therefore, it is necessary to develop a large-scale pig farm wastewater recycling annular sedimentation tank to solve the above problems.
