Paper Title:
Degradation of Hydroquinone by Pulsed Corona Discharge Combined with Ozone Process
  Abstract

Owing to toxicity of pharmacy wastewater to microbe, commonly used biodegradation is often limited in application; accordingly exploiting new ways of the wastewater treatment with high efficiency is a hot topic. As a new efficient advanced oxidation, pulsed corona discharge combining with ozone is attracting more and more attention. In this study, a special reactor was designed, in addition, the removal of TOC(Total Organic Carbon) and COD (Chemical Oxygen Demand)of simulant pharmacy wastewater containing hydroquinone (500mg/L) by pulsed corona discharge combining with ozone were investigated . It was showed that the TOC and COD removal (53.8% and 72.3%) by the combined technology was much higher than by using the two techniques in series when all the samples were treated 40mins.The two methods in combination have a synergistic effect. TOC and COD removal could be improved obviously when NaCl feed concentration increased from 0 to1000 mg/L, yet further increase in NaCl feed led to a markedly decrease removal efficiency of TOC and COD.
