为提高 SBBR 系统处理工业榨菜废水能力，通入一定的电流，首先考察电流对 COD 的去除效果及 SVI 的变化情况，随后考察不同电流强度对 COD、TN 及 TP 的去除效果的影响。结果表明：当 HRT：12 h，厌氧/缺氧：2 h，曝气：8 h，厌氧：1.5 h 时，通入一定量的电流能提高 SBBR 系统对榨菜废水的处理能力；当电流强度为50 mA 时，对 COD、TN 及 TP 的去除效果性价比最高，去除率分别为78.96%、69.49%及62.81%，出水浓度达到 GB 8978—1996《污水综合排放标准》表2中的三类标准，为今后工业榨菜废水处理提供了参考。

in order to improve the treatment ability of industrial mustard wastewater,current was in-troduced to the SBBR system. At first we maintained the current at a constant intensity to observe the removal rate of COD and changing trends of SVI,and then changed the current intensity to investi-gate the effect of current with different intensity on the removal rates of COD,TN and TP. The re-sults showed that at the following conditions:HRT:12 h,time interval of anaerobic / anoxic:2 h, aeration:8 h,and anaerobic:1. 5 h,the treatment effect of SBBR system for industrial mustard wastewater could be improved with a certain level of current introduced. And when the current densi-ty was set at 50 mA,the best cost - performance could be achieved for COD,TN and TP removal. The removal rates reached up to 78. 96% ,69. 49% and 62. 81% respectively,and the 3 pollutants in the effluent could meet the class 3 standard of Table 2 in Integrated Wastewater Discharge Stand-ard(GB8978 - 1996). The conclusion of this paper may provide reference for treatment of industrial mustard wastewater in the future.
