Municipal sewage treatment equipment

Abstract

The invention discloses municipal sewage treatment equipment, which comprises a pool body, a fixing frame, a first motor, an aeration blade, an aeration plate and a blast blower, wherein the top of the pool body is fixedly connected with the fixing frame; the lower surface of the fixing frame is fixedly connected with the first motor; the shaft extending end of the first motor is fixedly connectedwith a driving shaft; the aeration blade is hinged onto the driving shaft; a stirring shaft is arranged under the driving shaft; a stirring rod is distributed on the stirring shaft; the aeration plate is hinged to the bottom of the pool body; the blast blower is used for performing aeration on the bottom layer sewage; the aeration blade always floats on the water surface; the aeration blade is used for raising the surface layer sewage; the surface layer sewage is subjected to aeration; the stirring rod is used for stirring the sewage; bubbles in the sewage are broken, so that the mixing of the air and the sewage is more uniform; the contact is more sufficient; the aeration effect is improved; in the aeration process, the aeration plate leftwards and rightwards swings; the aeration range is expanded; meanwhile, the aeration plate is used for stirring the bottom layer sewage, so that the bottom layer sewage is upwards turned; the sewage aeration is more uniform.

Description

technical field [0001] The invention relates to the field of municipal engineering equipment, in particular to municipal sewage treatment equipment. Background technique [0002] The random discharge of sewage will have a great negative impact on the environment. At present, people often use aeration tanks to treat sewage. The aeration tank is a structure that uses activated sludge method for sewage treatment. The system and the water inlet and outlet are composed of three parts. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and it is difficult to meet people's growing sewage treatment needs.
