This device usually includes multiple treatment stages, each with specific functions and effects, including: pretreatment stage, chemical treatment stage, physical treatment stage, and biological treatment stage.

[0003] The industrial wastewater multi-stage purification device has many advantages. It can effectively remove various types and concentrations of pollutants, improving the efficiency and quality of wastewater treatment. Moreover, through multi-stage treatment, targeted treatment of different pollutants can be achieved, resulting in more precise and efficient purification.

[0004] In the patent application with publication number CN115594327A, an environmentally friendly sewage purification treatment device with detection function is disclosed, which includes a primary purification device, a secondary purification device, and a tertiary purification device. The primary purification device is installed with a first liquid discharge pipe at the lower end of one side. The secondary purification device is installed near the first liquid discharge pipe and is installed with a second liquid discharge pipe at the lower end of one side. Meanwhile, the secondary purification device is installed with a third liquid discharge pipe on the other side. The tertiary purification device is installed near the third liquid discharge pipe and is installed with a detection box at the lower end of one side. This environmentally friendly sewage purification treatment device with detection function is equipped with a primary purification device, a secondary purification device, a tertiary purification device, and a detection box. After multiple cycles of purification, harmful and toxic substances in the sewage are removed, and the detection box is used to detect the purification degree, so that the discharged sewage does not harm the environment and soil, effectively improving the purification effect.
