摘要
A coupled coagulation and supercritical water oxidation have been applied to treating an industrial wastewater coming from the use of an alkaline cleaning solution. After the proposed treatment, the wastewater fulfilled Chinese regulations for sewage discharge. First, phosphorous was eliminated by coagulation with FeSO4 and then chemical oxygen demand (COD) was removed via supercritical water oxidation. The supercritical water oxidation showed to be very effective to treat this particular wastewater in 30 min. The experiments performed at a bench scale allowed to propose a scheme for the in situ treatment of the alkaline cleaning solution wastewater, which could be extended to other similar wastewaters.
