NOVELTY - The utility model claims a graphene composite antibacterial material experiment device, comprising a steel barrel, filter, an ultraviolet lamp tube, a support, a peristaltic pump, a water storage tank and a collecting bottle, the upper and lower bottom of the barrel are respectively provided with three holes; and cut a small door on the periphery, the column inserted into the shell through the middle hole of the barrel and lower bottom and a filter column part in the shell is a filter material layer, the ultraviolet lamp tube enters the shell through left and right holes of barrel bottom, and it is fixed by upper and lower lamp holder, the support for fixing the barrel and filter, the peristaltic pump by a hose connected with the column. The device uses new bacterial graphite/copper-zinc oxide composite material and cheap to obtain walnut shell powder as material, adding ultraviolet light auxiliary irradiating and improve the antimicrobial performance of the filter material, capable of effectively removing the microorganism in the sewage.
