NOVELTY - The utility model relates to the field of experimental devices, and provides a graphene pretreatment device for separating and enriching phenolic organics in water, comprising a box, a water inlet pipe, a flow meter, a peristaltic pump, a graphene extraction column, a battery power source, a DC stabilized power source, and a time controller for setting the water inlet time, wherein the peristaltic pump is set in the integrated box, the water inlet pipe is connected with the water inlet of the peristaltic pump, the water outlet of the peristaltic pump is connected with the graphene extraction column, the time controller is connected to the peristaltic pump, the battery power source is connected to the time controller, and the battery power source provides power for the peristaltic pump and the time controller. The pretreatment device can separate and enrich low-concentration phenolic organics in water bodies, and can overcome the problem that conventional instruments such as ultraviolet spectrophotometers are difficult to directly detect when the concentration of phenolic organics in water bodies is too low. The utility model is used in combination with a phenol rapid test box (color card and color test box patent number: ZL201720323031.X), which can quickly and qualitatively and semi-quantitatively detect phenol organic compounds in water on site.
