Abstract
A saline wastewater treatment method is provided. Raw water is pretreated to obtain pretreated raw water. The pretreated raw water is pressurized to a preset pressure, injected with zone, separated and filtered by a filtering device with a hollow fiber nanofiltration membrane or a hollow fiber reverse osmosis membrane inside to obtain a concentrate and a permeate. A pressure of the concentrate is controlled such that ozone in the concentrate is released to form micro-nano bubbles. The concentrate is partially injected into the pretreated raw water. A pressure of the permeate and a pressure of the raw water are respectively controlled such that ozone in the permeate and the raw water is released inside the filtering device to form micro-nano bubbles to flush the hollow fiber nanofiltration membrane or the hollow fiber reverse osmosis membrane. A saline wastewater treatment system is also provided.
