Problems solved by technology

The existence of foam is relatively harmful. If some sludge is brought out, it is easy to cause a large amount of sludge return and increase the cost; the concentration of dissolved oxygen is reduced, which is not conducive to the growth of aerobic bacteria; while the conventional aeration tank solves the problem of foam The best way is to add defoamer, and for most sewage, the chemical composition inside is complex, and the chemical composition in sewage has a great influence on defoamer, so the effect of defoamer is not good. obvious

Abstract

The invention discloses an oxidation ditch using air-injecting extrusion for defoaming. The oxidation ditch comprises an oxidation ditch body, and the oxidation ditch body comprises an oxidation ditch sidewall A, an oxidation ditch sidewall B and a rotating shaft. A bearing seat A is mounted on the oxidation ditch sidewall A, and a bearing seat B is mounted on the oxidation ditch sidewall B. The rotating shaft which is a hollow pipeline penetrates the bearing seat A and the bearing seat B and can rotate in the bearing seat A and the bearing seat B freely, a motor is connected at one end of the rotating shaft and drives the rotating shaft to rotate, and a rotating output shaft of the motor is connected with the rotating shaft. A plurality of foam breaking rods are arranged on the circumferential face of the rotating shaft, an axis of each foam breaking rod is perpendicular to that of the rotating shaft, an air supply pump is communicated at the end, far away from the motor, of the rotating shaft, and the rotating shaft is provided with a plurality of air outlet micropores which are formed in areas between adjacent foam breaking rods.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an oxidation ditch for eliminating foam by jet extrusion. Background technique [0002] Oxidation ditch is a sewage treatment device that introduces air into the sewage tank to increase oxygen treatment of sewage. During the oxidation ditch treatment process, a large amount of foam is often generated. For the above foam, generally no treatment or defoaming agent is used to process. The main reason for foaming is the presence of some chemical components in the wastewater. These chemical components are sheared into small molecules under the strong hydraulic shear force of the low-pressure jet aeration system, and combined with fine air bubbles to form foam. The existence of foam is relatively harmful. If some sludge is brought out, it is easy to cause a large amount of sludge return and increase the cost; the concentration of dissolved oxygen is reduced, which i...
