Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an interception device. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment involves introducing it into a sedimentation tank for sedimentation, followed by subsequent purification. During this introduction, large floating debris within the wastewater must be intercepted to prevent it from flowing into the sedimentation tank or into subsequent treatment equipment, potentially clogging the purification equipment.

[0003] During interception, floating garbage is intercepted by a net, and then manually salvaged. This process is repeated. Since the garbage is not concentrated enough and is distributed outside the net, manual cleaning requires walking back and forth, which increases the difficulty of cleaning and the labor intensity.
