摘要
Groundwater micropollutant has been a steady threat to the rural residents with household-based water supply. In this work, a multi-barrier technology is designed, that is, rice husk ash (RHA) adsorption and enhanced coagulation, followed by heating and boiling (azotropic). The removal efficiency of nitrobenzene from groundwater was investigated using this household-based combined process. The experimental results indicate that the nitrobenzene concentration can be under the limit determination in the finished water, treated by the combined process. Ames test indicates that the combined process, especially RHA, is safe and reliable. The combined process is a cost-effective technology for emergent nitrobenzene removal in decentralized water supply.
