A method of recycling semiconductor wastewater comprises the steps of: injecting a first sodium hydroxide(NaOH) into semiconductor wastewater to provide the semiconductor wastewater with a hydrogen ion concentration ranging from 8.5 to 9.5 pH; passing the semiconductor wastewater through a weak acid cation ion-exchange resin to remove calcium(Ca) and magnesium(Mg) from the semiconductor wastewater; injecting hydrochloric acid(HCl) into the semiconductor wastewater to provide the semiconductor wastewater with a hydrogen ion concentration ranging from 2 to 3 pH; removing carbonic acid gas(CO3) from the semiconductor wastewater; injecting a second sodium hydroxide(NaOH) into the semiconductor wastewater to provide the semiconductor wastewater with a hydrogen ion concentration of at least 10 pH; and removing salts and organic carbons from the semiconductor wastewater by high efficiency reverse osmosis. Further, a step of adding NaOCl into the semiconductor wastewater before adding the first sodium hydroxide is additionally comprised.
