Background

A sedimentation tank of water treatment units such as sewage treatment plants, water works and the like is a structure for removing suspended matters in water by sedimentation and is equipment for purifying water quality. The natural precipitation or coagulating sedimentation of water is used to remove suspended substances in water.

In the daily water treatment process of the sedimentation tank, a large amount of sludge floating up of the sedimentation tank often occurs, namely, the sludge floats on the surface of the sedimentation tank to form floats. The floating object floats on the water surface, has a loose structure, is easy to flow out along with water, greatly increases the content of SS (Suspended Solids) after water treatment, and can lead to substandard discharge after water treatment when serious.

In order to reduce the floating matters generated by the floating of the sludge in the sedimentation tank, measures such as increasing the oxidation-reduction potential of the sedimentation tank, controlling the organic load, uniformly stirring and circulating, adjusting the operation parameters of the sedimentation tank and the like can be adopted, but the measures only reduce the floating matters, but cannot stop the floating matters. Therefore, when the floats appear in the sewage pool, the floats still need to be cleaned in time, so that the water is prevented from reaching the standard after being treated.
