Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to an aquaculture wastewater treatment device. Background Technology

[0002] A livestock farm is a place where a certain number of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, foxes, minks, otters, and quails, are concentrated in a specific area for unified breeding and raising. During the breeding process, livestock farms need to clean the breeding sheds, which generates a large amount of wastewater. Because the wastewater contains a large number of bacteria and has high levels of ammonia nitrogen and organic phosphorus, it needs to be discharged into a wastewater pond for unified sterilization and treatment with added chemicals before being released.

[0003] During the wastewater treatment process, a significant amount of debris accumulates at the bottom of livestock farm wastewater ponds, requiring regular cleaning to prevent it from hindering treatment effectiveness. Current methods typically involve draining the pond and then manually cleaning the bottom, a tedious process that requires workers to enter the pond. Since livestock manure in the wastewater is harmful to human health, prolonged manual cleaning can cause dizziness and other health problems. Furthermore, debris in the wastewater easily adheres to the filter screen, clogging the pores and reducing filtration efficiency. Therefore, this paper proposes a livestock wastewater treatment device to address these issues. Utility Model Content

[0004] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a wastewater treatment device for aquaculture. By setting a scraper with an inclined surface at the top, a drive mechanism is used to drive the scraper to move upward and be on the same plane as the guide plate, scraping off the debris attached to the filter screen.

[0005] (II) Technical Solution This utility model provides a wastewater treatment device for aquaculture, including a wastewater tank, a filter screen, and a stirring mechanism. The filter screen is disposed inside the wastewater tank, and the stirring mechanism is disposed inside the wastewater tank and located to the left of the filter screen. It also includes a scraper, a guide plate, and a filter box. The scraper is close to the left side of the filter screen. An installation groove is provided on the front side of the wastewater tank, and the guide plate is connected to the installation groove.
