H2O2-based advanced oxidation processes (AOPs) and SO4·--based AOPs were proved novel and promising techniques in treatment of wasterwater. Microwave (MW)-assisted hydrogen peroxide (H2O2), peroxymonosulfate (PMS) and persulfate (PS) were used to dispose of COD in landfill leachate. Oxidant dosage and chloride concentration were investigated as the major operating conditions. The initial COD is 4062...
Due to its high-temperature nature, high-temperature dyeing wastewater is a major challenge for treatment. In this paper, using the high thermal energy of high-temperature printing and dyeing wastewater to activate persulfate (PS) for dye treatment was investigated. Acid orange 7 (AO7) was chosen as a model compound. The result shows that increasing the temperature or PS concentration is beneficial...
Seawater substitution is one of the effective routes to alleviate the shortage of water resources, and its high saline matter can be used in printing and dyeing industry. However, the treatment of the formed dyeing wastewater is difficult for the high salt. This paper using ultraviolet (UV) light to activate persulfate (PS), hydrogen peroxide (H2O2), Oxone (PMS) to degrade azo dye Acid orange 7 (AO7)...
