Description

Technical Field

[0002] In the process of various engineering constructions, the application of three-stage sedimentation tanks is crucial. The three-stage sedimentation tank is the core part of sewage treatment at the construction site. Through physical methods, suspended solids and solid particles in sewage are effectively deposited, achieving the purpose of purifying water quality. It has high sedimentation effect and wastewater treatment capacity. Whether its treatment capacity is efficient or not is directly related to the project investment, on-site construction progress, and the quality of environmental water protection management.

[0003] Conventional three-stage sedimentation tanks generally only build three juxtaposed or continuous sedimentation tanks, and the water flow passes through them in sequence for sedimentation treatment. During use, regular silt cleaning is required, resulting in the shutdown of the sedimentation tank, which in turn leads to the suspension of water use construction operations and affects the project progress. Moreover, the sedimentation tank is generally rectangular, and it is very difficult to clean the deposited silt thoroughly using conventional mechanical equipment. In view of the current increasingly strict environmental water protection policies, tight construction periods, and high construction intensities, the sewage treatment efficiency, working hours, and silt cleaning quality of conventional three-stage sedimentation are difficult to meet the requirements, which is not conducive to project management.
