Description

Technical Field

[0001] The utility model relates to the technical field of sediment filtration, and more specifically, to a gradient ladder-type filtering device for treating sewage containing sediment. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the required water quality for discharge into a water body or reuse. Wastewater treatment is widely used in various fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is increasingly becoming part of everyday life.

[0003] Sewage contains a large amount of solid matter such as silt and needs to be pretreated. The existing equipment for gradient ladder-type silt filtering transfers the silt in the water flow to the silt storage area through the ladder-type filter plate without affecting the water flow. When the filter plate filters the silt, the silt may be stuck in the filter holes. Usually, a rotating brush roller is used to clean it, but the cleaning force is not strong enough, which affects the filtering effect.

[0004] In view of this, research and improvement are carried out on the existing problems, and a gradient ladder filtration equipment for the treatment of sediment-containing sewage is provided, aiming to achieve the purpose of solving the problem and improving the practical value through this technology.
