Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture wastewater treatment, in particular to aquaculture wastewater pretreatment equipment for livestock and poultry breeding. Background Art

[0002] The wastewater produced in pig farms contains a large amount of feces and a large amount of suspended matter, which is a high-concentration organic wastewater. When this untreated wastewater enters natural water bodies, it will increase the content of suspended solids, organic matter and microorganisms in the water, change the physical, chemical and biological community composition of the water body, and deteriorate the water quality. In addition, the wastewater also contains a large number of pathogenic microorganisms that will spread through the water body or through aquatic plants and animals, endangering the health of humans and animals.

[0003] Traditional aquaculture wastewater treatment equipment only has a simple filtering structure that can filter out impurities such as feces in the wastewater. However, the filtered impurities are not easy to clean after filtering. Usually, the impurities on the filter components are removed manually using external equipment, which is time-consuming and labor-intensive, and difficult to operate and inconvenient to use, thus affecting the efficiency of sewage treatment.

[0019] In the above arrangement, the aquaculture wastewater passes through the water inlet 2 and the outlet water passes through the filter tank 1. In this process, the first filter cloth 8 blocks the suspended matter in the aquaculture wastewater, wherein the first filter cloth 8 is preferably a non-woven filter material, and the filtration mesh is selected according to the particle size of the suspended matter in different aquaculture wastewaters. During the filtration process, the reduction motor 10 drives the power reel 9 to slowly pull out the first filter cloth 8 wound on the first reel 5 and wind it, so as to realize the automatic update of the filtration position of the first filter cloth 8 until the first filter cloth on the first reel 5 is used up.
