Foam eliminating equipment for sewage treatment aeration tank

Abstract

The invention discloses foam eliminating equipment for a sewage treatment aeration tank, the foam eliminating equipment comprises a translation mechanism and a connecting mechanism, wherein the innerside of the lower end of the translation mechanism is provided with the connecting mechanism; the translation mechanism comprises a translation motor, a translation frame, connecting strips, pulleys,rotating rods, guide sleeve plates and a bottom limiting plate; one end of the translation motor is provided with the two rotating rods; the pulleys are respectively arranged on the outer sides of twoends of the rotating rods; and the outer sides of the middle parts of the rotating rods are provided with the connecting strips. The upper end face of the connecting strip is provided with a translation frame, the upper end face of the translation frame is provided with a foam eliminating motor, the inner side of the translation frame is provided with the five guide sleeve plates, the lower end face of one of the guide sleeve plates is provided with the bottom limiting plate, and the lower end faces of two pulleys are provided with slide rails. According to the invention, foam generated in the aeration tank is eliminated, the operation safety is improved, the foam generation amount is effectively controlled, and the effluent quality is ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a device for eliminating foam in an aeration tank for sewage treatment. Background technique [0002] With the rapid development of social economy, people's domestic and industrial wastewater is more and more, and sewage treatment is paid more and more attention. In the process of sewage treatment, the aeration tank is used for aeration treatment. In the designed biochemical reactor, the degree of degradation of organic pollutants mainly depends on the aeration reaction conditions designed by people. The aeration tank uses the activated sludge method for sewage treatment, and a certain sewage residence time is provided in the tank to meet the needs of aerobic microorganisms. The amount of oxygen and the mixing conditions for full contact between sewage and activated sludge. [0003] However, foaming will occur in the existing aeration tank, which will affect the operati...
