Abstract： |
The method is to do photochemical oxidizing reaction to sewage preprocessed by chemical coagulating sedimentation. Special photochemical oxidizing apparatus is used to make sewage being fully mixed with nanometre photochemical catalyst powder on condition of lighting, then producing photochemical oxidizing reaction, thus harmful substances are oxidized and reducted. |
