Abstract

Toxic micropollutants in rainwater challenge the effective reuse of rainwater. This study proposed the application of newly developed vacuum-ultraviolet (VUV) in the advanced treatment of rainwater, and assessed the efficiency and feasibility in application. The VUV was generated from the UV lamp made of the new special silica. Benzoic acid, p-hydroxyl benzoic acid, bisphenol A, p-chlorobenzoic acid, nitrobenzene, and p-chloronitrobenzene were selected as target compounds. Their degradation efficiency was evaluated, and the degradation kinetics were also analyzed. Influence of pH was investigated, and the degradation mechanisms were explored by distinguishing the individual contributions of different radicals involved. The efficiency of VUV was further compared with that of H2O2/UV process, and its advantages were consequently discussed when applied in the practical rainwater treatment. The results obtained here will support the VUV irradiation as an promising treatment process for the purification of rainwater for the centralized and decentralized systems to guarantee the safety of the rainwater reuse.
