Ultrasonic accelerating sewage settling tank

Abstract

The invention discloses an ultrasonic accelerating sewage settling tank. The ultrasonic accelerating sewage settling tank comprises a settling tank, a drain tank, a deodorization device and a sludge pump, wherein cover plates are arranged at the tops of the settling tank and the drain tank; an ultrasonic generator is arranged inside the settling tank and positioned below a water inlet pipe; the ultrasonic generator is connected with an ultrasonic vibrating plate in the settling tank; a polyester fiber layer, a perforated polyester foam layer and an asphalt mineral wool layer are arranged fromthe upper part to the lower part at the bottom of the settling tank; a sludge outlet is formed in the lowest end at the bottom of the settling tank; the drain tank is arranged on one side, far from the water inlet pipe, of the settling tank. The ultrasonic accelerating sewage settling tank can conveniently clean sludge formed by accumulating suspended solids by being provided with the ultrasonic generator and the ultrasonic vibrating plate, effectively absorbs ultrasonic energy and reduces the generation of reflected wave when ultrasonic wave is in contact with the polyester fiber layer, the perforated polyester foam layer and the asphalt mineral wool layer at the bottom of the settling tank, is convenient for the sludge to be discharged from the bottom of the settling tank by setting thebottom of the settling tank to be turbinate, and improves the sludge cleaning efficiency.

Description

technical field [0001] The invention relates to a sedimentation tank, in particular to an ultrasonic accelerated sewage sedimentation tank, and relates to the technical field of sewage treatment. Background technique [0002] With the continuous progress of society, especially the rapid development of industrialization and urbanization, people's lives have been greatly improved and improved. At the same time, as people enjoy the fast-paced happy material life and spiritual life, they are A large amount of domestic pollutants including sewage are continuously produced, and industrial sewage discharge is even more serious. [0003] In order to be able to treat the purified sewage well, the sewage will be purified through the discharge port or centralized treatment of sewage. Since the water purification treatment system requires a large area and many processes, many pairs of purification treatment systems in the prior art The multiple equipments are divided and placed, and co...
