Embodiment 1

[0061] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0062] This embodiment discloses a sewage treatment device, combining figure 1 The schematic diagram of the device structure shown, the device includes:

[0063] The grid flocculation tank 1 and the biological treatment tank 2 are connected in sequence. The outlet of the biological treatment tank 2 is connected to the lower part of the photocatalytic tank 4 through the first pump 3, and the first pump 3 transports the sewage from the biological treatment tank 2 to the photocatalytic tank 4. The sewage is transported to the ...

Embodiment 2

[0097] This embodiment discloses a specific control method of the sewage treatment device provided in Embodiment 1.

[0098] In this example, combined with figure 2 As shown in the flow chart, the control method includes the following steps:

[0099] Step 1: Control the sewage to enter the grid flocculation tank and the biological treatment tank in sequence; including steps S11: water intake, S12: water enters the grid flocculation tank, S13: water enters the biological treatment tank; the water enters the biological treatment tank for preliminary treatment, and the Most of the organic and inorganic substances are removed.

[0100] Step 2 (S14): Control the start of the first pump to transport the sewage from the biological treatment tank to the lower part of the photocatalytic tank; the effluent of the biological treatment tank, such as the microbial reaction tank, may be difficult to meet the corresponding standards, such as for printing and dyeing wastewater In other wor...
