Description

TECHNICAL FIELD

[0001] The utility model relates to wastewater treatment technical field especially, relates to a kind of wastewater recycling device for amino acid feed production. BACKGROUND

[0002] In the production process of amino acid feed, a large amount of wastewater rich in high-concentration organic matter, nitrogen, phosphorus and other components will inevitably be produced. If such wastewater is discharged directly without treatment, it not only wastes valuable water resources, but also may cause environmental pollution problems and pose a threat to ecological balance. Therefore, efficient treatment and recycling of such wastewater have become a key problem that needs to be solved in the industry.

[0003] Traditional wastewater recycling devices usually use a treatment method of adding treatment agents and mixing with wastewater before filtration. However, due to the mixing and stirring action, a large amount of impurity particles often accumulate on the water surface during this process. Existing devices generally lack a special impurity capturing mechanism and cannot effectively remove these impurities floating on the water surface in time, thereby increasing the burden of the subsequent filtration process. In addition, traditional devices often rely only on a single layer of filter screen or filter cloth simply arranged in the pipeline during the filtration process. This design is prone to cause impurity particles to gradually accumulate and block the filter holes on the filter screen after a long period of use, which not only significantly reduces the filtration efficiency, but also forces operators to frequently interrupt the filtration process for equipment cleaning, greatly affecting the convenience and continuity of use.
