Abstract
The invention provides a treatment system and a treatment method for PMIDA high-salinity wastewater. The treatment system includes a booster pump, a water inlet-outlet heat exchanger, a water inlet heater and an oxidation reactor, and the water inlet-outlet heat exchanger is provided with a wastewater inlet, a wastewater outlet, an oxidized water inlet, and an oxidized water outlet. An oxidized water from the oxidation reactor enters the water inlet-outlet heat exchanger through the oxidized water inlet, the oxidized water outlet is connected to an intermediate tank, the wastewater inlet is connected to the booster pump, and the wastewater outlet is connected to a wastewater heater. A micro-interface unit is disposed at the lower part in the oxidation reactor, for dispersing crushed gas into bubbles. A gas inlet is formed at a side wall of the oxidation reactor and is connected to the micro-interface unit through a pipeline.
