The invention discloses a system and a method for treating water recycled from straw pulp papermaking wastewater. The system is formed by sequentially or respectively connecting a regulating tank, a primary efficient coagulative precipitation tank, a secondary efficient coagulative precipitation tank, a middle water tank, an ultrafiltration membrane treatment device, a reverse osmosis membrane treatment device, an ozone contact oxidation tower, an active carbon adsorption tower, an acid regulating tank, a higher oxidization reaction tank, a neutralizing precipitation tank and a water-producing tank. The system organically combines the coagulative precipitation treatment, the higher oxidization treatment, the ozone catalysis oxidation treatment and the treatment of an ultrafiltration membrane and a nanofiltration membrane, treats the water recycled from the straw pulp papermaking wastewater by using a physical and chemical treatment technology and a shunting treatment and combined effluent ...
