Abstract
[Objective] The reference for the scientific treatment of domestic sewage was provided through the experiment. [ Method] The effect of the reaction time of activated carbon-filling, the voltage and distance between plates, and the additives on three-phase/three-dimen sional electrode method treating the domestic sewage was analyzed. [Results] The longer the reaction time was, the better the treatment effi ciency was; however, the using rale of electrial power was reduced because of the the by-reaction increasing. There was an optimal reaction time, which made the absorption rate being almost equal to the oxidation rate. The elimination rate was elevated with the increment of input voltage and the treatment efficiency would be stable while the voltage reached to the certain value. The elimination effect would be reduced while the distance between plates. The addition of NaCl did not affect the treatment. When the electrolysis time was 30 minutes with the energy consumption of 2.84 kW · h/kg,about 85％ of the removal rate of COD in domestic sewage could be stabilized and the removal rate of NH3-N was about 84％. [ Conclusion ] It was feasible for the domestic sewage to be treated with the method of three-phase/three-dimensional elec trode and under the suitable condition there was a high removal rate of COD and NH3-N.关键词
