Municipal sewage treatment and purification equipment and implementation method thereof

Abstract

The invention discloses municipal sewage treatment and purification equipment and an implementation method thereof, and belongs to the technical field of sewage treatment and purification, the municipal sewage treatment and purification equipment comprises a primary oxidation pond, a support frame and a medicine tank, a treatment tank is mounted on the support frame, and water pumps arranged on the primary oxidation pond and the medicine tank are connected with the treatment tank; and a rotating assembly, a moving assembly and a conveying assembly are respectively mounted on the treatment tank. According to the municipal sewage treatment and purification equipment and the implementation method thereof, a disc reciprocates in an inner treatment cylinder, a part of a mixture can flow through the through holes due to the arrangement of the multiple rows of through holes, and the diameter of the through holes is small so that the flowing speed of liquid can be increased; and a part of liquid pushed by the disc does not pass through the through holes, but is pushed by the edge of the disc to move towards a baffle to form a part of vortex, and the vortex is destroyed after the vortex is matched with the rotation of the baffle, so that the stable state of the mixture is continuously destroyed, the mixing speed is increased, and meanwhile, the problem of non-uniform mixing at a dead angle is solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and purification, in particular to a municipal sewage treatment and purification equipment and an implementation method thereof. Background technique [0002] With the continuous improvement of people's living standards, domestic sewage discharge is becoming more and more serious. The municipal pipe network also needs to manage the sewage treatment while managing the rainwater treatment, which not only increases the working pressure of the municipal pipe network, but once the pipe network is overloaded, it is easy to cause the deterioration of water resources in some areas. [0003] Sewage treatment device is an indispensable equipment in municipal pipe network. The effect of its sewage treatment directly affects the working stability of municipal pipe network. The sewage treatment device in the prior art can only be used for the treatment of a small part of sewage. In recent years, In m...

The municipal pipe network also needs to manage the sewage treatment while managing the rainwater treatment, which not only increases the working pressure of the municipal pipe network, but once the pipe network is overloaded, it is easy to cause the deterioration of water resources in some areas

[0003] Sewage treatment device is an indispensable equipment in municipal pipe network. The effect of its sewage treatment directly affects the working stability of municipal pipe network. The sewage treatment device in the prior art can only be used for the treatment of a small part of sewage. In recent years, In municipal sewage treatment involving sewage standard upgrading, high-density sedimentation tanks, high-efficiency sedimentation tanks, sand clarification tanks and other processes are applied to projects. These processes are widely used, have good impact resistance and stable operation, and on this basis The magnetic coagulation sedimentation tank under research and development has been recognized by the sewage treatment industry due to its advantages of smaller footprint and compact structure. However, when using high-density sedimentation tanks, high-efficiency sedimentation tanks and subsequent treatment, it is necessary to achieve chemical purification by dosing , and in order to increase the speed of its purification, it is mixed by means of stirring, and the way of stirring and mixing has the problem of stirring dead angle
