Description

Technical Field

[0001] The utility model relates to the technical field of treatment equipment, in particular to multi-stage biological sludge treatment equipment. Background Art

[0002] As we all know, sludge refers to a mixture formed after removing impurities such as solids, liquids and gases from sewage during the sewage treatment process. Usually, sludge needs to be treated with sludge treatment equipment. Sludge treatment equipment is a device specially used to treat sludge produced by sewage treatment plants, sewage treatment equipment, etc. It usually removes water from the sludge, reduces its volume, and reduces the content of pollutants through physical, chemical or biological methods, and finally achieves the treatment and disposal of sludge. Sludge treatment equipment can effectively reduce pollution to the environment, and at the same time, it can also utilize sludge as a resource to achieve resource recycling, which is in line with the concept of sustainable development.

[0003] However, traditional sludge treatment equipment usually contains a large number of particles of different sizes and organic matter in the sludge, and usually a large amount of water is used for flushing to separate the particles and organic matter in the sludge. A large amount of clean water is used to flush the sludge, but this water cannot be recycled, resulting in a waste of water resources. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a multi-stage biological sludge treatment device. When the sludge treatment device is used, the sludge is transported from the sewage inlet pipe to the treatment barrel by opening the electric control valve, the water in the purification barrel is extracted from the water suction end by starting the first water pump, and the water is transported to the annular pipe through the water outlet end, and the water is sprayed to the surface of the sludge by the liquid spray head, and the particles and organic matter in the sludge are screened through the screening holes in the first screening plate and the second screening plate. At this time, the second servo motor is started to drive the rotating rod to rotate. At the same time, it drives the transmission gear and the rack to rotate, and the rack rotation drives the conveying pipe and the centrifugal barrel to rotate, and the centrifugal barrel rotates to drive the screened sludge to be thrown. The centrifugal force generated by this will cause the solid particles in the sludge to settle on the wall of the centrifugal barrel to form a solid sedimentation layer, while the water is squeezed out along the membrane holes to the outside of the centrifugal barrel. By starting the second water pump, the squeezed liquid is transported to the purification barrel, and then the sludge is flushed for a second cycle, so as to facilitate the recycling of the separated water resources and reduce the waste of water resources.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
