Abstract: Provided are a system and a method of treating wastewater. The system includes a wastewater chamber, positive and negative electrode chambers, acid and basic solution chambers and a buffer chamber. The wastewater chamber receives wastewater containing a first ion. The positive and the negative electrode chambers are respectively on opposite sides of the wastewater chamber. The acid chamber is between the wastewater chamber and the positive electrode chamber. The basic chamber is between the wastewater chamber and the negative electrode chamber. The buffer chamber is between one of the acid and the basic chambers and the wastewater chamber, and receives the buffer solution containing the first ion. The interfaces between the wastewater chamber and the buffer chamber and between the one of the acid and the basic chambers and the buffer chamber are ion exchange membranes having the same electrical properties.

Abstract: A device for recycling sulfuric acid is provided. A container has an inner space. An inlet is located on the first side of the container for introducing a liquid containing sulfuric acid and hydrogen peroxide through a pump. An outlet is located on the second side of the container for exhausting the treated liquid from the container, and the first side and the second side are opposite sides. IR lamp and UV lamp are located in the inner space of the container for making contact with the liquid. IR radiation emitted from the IR lamp and UV radiation emitted from the UV lamp decompose the hydrogen peroxide in the liquid to water and oxygen. The IR radiation heats the liquid to 90° C. to 130° C., and the oxygen is exhausted through the air hole.

Abstract: Provided are a system for treating wastewater and a cleaning method thereof. The wastewater treatment system includes: a wastewater compartment, a first electrode, a second electrode, an acid compartment, a base compartment, an acid supply apparatus, a base supply apparatus, a control apparatus, and a power supply device. During the cleaning process, the power supply device provides reverse potential to the first and the second electrodes. The control apparatus shut off a first channel so that the acid supply apparatus provides an acid solution to the base compartment through a second channel, and shut off a third channel so that the base supply apparatus provides an alkaline solution to the acid compartment through a fourth channel, without shutting off the wastewater treatment system.

Abstract: An ion exchange resin and a method for preparing the same are provided. An ion exchange resin is formed by a composition, and the composition includes a crosslinking agent and an ionic compound with sulfonate ions. The ionic compound with sulfonate ions is formed by reacting an epoxy resin with an ionic monomer with sulfonate ions or an ionic polymer having sulfonate ions. The ionic monomer and the ionic polymer each has a hydroxyl group or an acid group at the ends. The ionic monomer or the ionic polymer is 40 to 80 parts by weight, and the epoxy resin is 15 to 25 parts by weight, based on 100 parts by weight of the ion exchange resin. An ion exchange resin with a network structure is formed after the ionic compound with sulfonate ions reacts with the crosslinking agent.
