Zusammenfassung:	The invention discloses an antibacterial agent, a novel antibacterial PVDF (Polyvinylidene Fluoride) hollow fiber ultrafiltration membrane and a preparation method, functional polyhexamethylene guanidine hydrochloride containing a carbon-carbon double bond functional group and acrylic acid are subjected to a copolymerization reaction to form the antibacterial agent, the addition amount of the functional polyhexamethylene guanidine hydrochloride accounts for 0.7-1.2 wt% of the total amount of a system, and in the copolymerization reaction process, the addition amount of the functional polyhexamethylene guanidine hydrochloride accounts for 0.5-1.5 wt% of the total amount of the system. Adding 1-3wt% of azodiisobutyronitrile as an initiator, and then stirring at the constant temperature of 70-85 DEG C to carry out copolymerization reaction for 6-8 hours. 2.5-4wt% of the antibacterial agent is added into the raw materials of the membrane material, and the ultrafiltration membrane is prepared through a blending pr
