Treatment device and method applicable to production wastewater

The invention discloses a treatment device and method applicable to production wastewater, and relates to the technical field of wastewater treatment. According to the key points of the technical scheme, the treatment device comprises a treatment tank, a water inlet pipe, a water outlet pipe, a gas inlet pipe fixedly connected to the treatment tank, a spraying pipe fixedly connected to the gas inlet pipe, a UV lamp fixedly connected to the inner wall of the treatment tank, and a feeding pipe fixedly connected to the treatment tank. The treatment method comprises the following steps that a, thewastewater is delivered; b, a first catalyst is added; c, a second catalyst is added; d, UV photocatalysis is conducted; and e, the wastewater is discharged, high-pressure gas is introduced into thewastewater through the position of the bottom of the treatment tank, the wastewater at the bottom is driven by the high-pressure gas to surge upwards, thus all positions of the wastewater can be evenly irradiated by UV light,
