[0002] With the development of the agricultural industry, agricultural waste fermentation technology has been widely used in biogas production, bio-fertilizer preparation, and other fields. However, the fermentation process of agricultural waste generates a large amount of wastewater, which is characterized by high concentrations of organic matter, high ammonia nitrogen content, and high levels of suspended solids.

[0003] In existing technologies, when treating agricultural waste fermentation wastewater, coagulants need to be added to coagulate the organic matter in the wastewater. Most existing devices rely on natural mixing, which takes a long time to settle. If a stirring device is added, a lot of chemical substances will remain on the stirring rod, making subsequent cleaning inconvenient. After sedimentation, the stirring rod will also hinder the collection of sediment. Utility Model Content
