[0002] The multi-stage gradient flocculation deep treatment device for paper mill wastewater adopts multi-stage gradient flocculation technology, which combines physical and chemical methods to effectively remove suspended matter, colloidal matter, color and organic pollutants in the wastewater, so that the wastewater meets the discharge standards or reuse requirements.

[0003] Upon investigation, the publication (announcement) number: CN220334914U discloses a continuous flocculation tank for sewage treatment. This technology discloses "a continuous flocculation tank for sewage treatment, wherein the lower ends of the opposing surfaces of the first flocculation tank body and the second flocculation tank body are fixedly connected to a connecting pipe with a valve, the lower ends of the first flocculation tank body and the second flocculation tank body are equipped with a sediment discharge structure, and the lower ends of the front walls of the first flocculation tank body and the second flocculation tank body are equipped with an observation window structure."
