| 摘 要：應用自制電催化氧化裝置對硫雙滅多威廢水的催化條件展開(kāi)研究。以陽(yáng)極板材質(zhì)、電流密度、氧化時(shí)間、板間距、廢水pH值等做考察因子，得出優(yōu)化條件：Ti／IrO-RuO板作陽(yáng)極，不銹鋼板作陰極，電流密度為30 mA·cm-2，氧化時(shí)間3 h，板間距2 cm，廢水pH值為6~9。優(yōu)化條件下，CODCr去除率達80%，B／C由0.03提高到0.45，有效去除硫雙滅多威農藥廢水主要特征污染源。 |

| Abstract：The treatment of Thiodicarb in wastewater using the electrochemical reactor was studied in this paper. Factors affecting the removal rate are investigated such as types of anode plate, current density, electrolysis time, distance between the electrodes, pH， etc. And then the optimal treatment conditions were determined. The removal rate of CODcr reached up to 80％ under the following conditions: the anode plate of Ti/IrO-RuO, current density of 30 mA·cm-2, electrolysis time of 3 h, the distance between the electrodes of 2 cm, pH of 6~9, B/C between 0.03 to 0.45. The main characteristic pollution sources were decomposed. |
