Description

A concentrating device for sludge wastewater treatment

Technical Field

The present application relates to the technical field of wastewater treatment, and in particular to a concentrating device for sludge wastewater treatment.

Background Art

Sludge wastewater treatment includes the process of reducing, stabilizing and harmless treatment of sludge by concentration, conditioning, dehydration, stabilization, drying or incineration. Sludge is composed of solid matter in the original wastewater and solid matter generated during the wastewater treatment process. The sewage treatment equipment in the prior art includes sedimentation equipment, chemical treatment equipment, disinfection equipment, deodorization equipment, etc. The sedimentation equipment is to simply precipitate the sewage so that the sludge in the sewage is precipitated on the bottom of the equipment. The chemical treatment equipment is to remove certain harmful elements in the sewage by chemical reaction. The disinfection equipment is to disinfect the sewage by disinfectants, etc., so that the disinfected sewage is safer. The deodorization equipment is to remove the odor in the sewage, and finally obtain qualified water that can be used again. The important step in the treatment of sludge wastewater is to concentrate the wastewater and reduce the volume of sludge wastewater.

Referring to the Chinese patent case with authorization announcement number CN217511304U, a sludge concentrating device for heavy metal wastewater treatment is disclosed, which belongs to the field of wastewater treatment technology. The key points of its technical solution include a cabinet body, the front side of which is movably connected with a cabinet door, and the inner cavity of the cabinet body is provided with a concentrating mechanism, which solves the problem that most existing sludge concentrating devices can only perform simple filtering of the sludge when concentrating the sludge, and cannot filter the wastewater multiple times, resulting in sludge particles still existing in the filtered wastewater, thereby poor wastewater treatment effect and increased difficulty in user operation.

However, in the above patent, the filter plate is arranged in the cabinet. When the sludge wastewater is initially filtered and enters the filter plate for secondary filtration, the filtered sludge will accumulate on the filter plate, which is easy to clog the filter plate and affect the efficiency of water output.

Therefore, those skilled in the art provide a concentrating device for sludge wastewater treatment to solve the problems raised in the above background technology.
