| Abstract |
| This research connected the SUS electrode with a negative and an electrode of SUS, Carbon, Cu and Zn with a positive a so that the removal efficiency of a heavy metal were practiced quality of plate, concentration of sample, plate gap residence time and voltage which were respectively charged. Especially, this study presents. the removal efficiency of Cu and Zn. The parameters tested operating both batch and continuous electrocoagulation were electrolytic plate, plate distance, and current density with removal efficiencies of COD, SS. Good water quality of treated effluent was obtained as COD<10.0mg/L, SS<10.0mg/L with AL and SUS plate. Only 35~50% of nitrogen in raw municipal wastewater was removal by AL and SUS plate. Electricity decomposition was used with a submerged Electrolysis process in this experiment, and there was low-concentration waste water, too, organic matter, nitrogen removal were practiced. After a response fixes influx 30 minutes dozing off, the volume flowing from 10 minutes. The COD removal rate that were a showed a high removal rate more than all reactor each 85%. The SS removal rate showed a comparatively similar removal rate. As electrode gap was increased in the same electric pressure, electric resistance of solution did. The survey showed similar results that removal efficiency was decreased because IR drop happened, as a result of creased electrode gap. According to a change of time, removal efficiency was showed comparatively steady removal rating from the early of reaction velocity. It took to 40 from 60 minutes to remove 70~88% Cu and Zn showed a parallel from on the whole. |
