The invention discloses an advanced treatment technology system for oilfield reinjection water. The advanced treatment technology system is characterized by comprising a first-stage water inlet pump, a filter water inlet, a multi-medium filter, a water distributor, a ceramic filler area, an activated carbon filler area, a filter water outlet, a backwashing pump, a backwashing water inlet, a backwashing water outlet, a middle pool, a second-stage water inlet pump, a catalysis tower water inlet, an ozone catalysis tower, a kaolin ozone catalyst, an ozone generator, an ozone pipeline, an ozone inlet, an ozone diffuser, an ozone quencher, an ozone outlet, a catalysis tower water outlet and a draining pump. According to the advanced treatment technology system, a technical scheme for advanced treatment of oil producing wastewater is presented, the problem that organic pollutants in the oilfield reinjection water exceed the standard is systematacially solved, and the oil producing wastewater treated by the system can meet the oilfield reinjection requirements; in addition, the treatment effect is stable, the production operation cost is low, and operation is easy and convenient.
