摘　　要：针对富马酸废水降解难的特点,采用电化学法对其进行了深度处理。研究结果表明,在相同操作条件下,有隔膜的独立电极电解与无隔膜的混合电解相比,在电解20 min时阳极侧与阴极侧的废水COD去除率分别降低了35%和50%;与添加电解质Na2SO4相比,添加可产生活性氯的NaCl有利于提高COD的去除率,在实验范围内,相应的COD去除率可达94.65%。电流效率ICE随富马酸废水中COD残留率的降低而降低,二者存在非线性关系,其中COD去除率>90%后,对应ICE<10%。Aiming at the problem that fumarate wastewater is difficult for degradation,the electrochemical process has been used for its advanced treatment. The results show that under the same operation conditions, after it is electrolyzed for 20 min,the corresponding COD removing rates of anode side and cathode side wastewater in independent electrolysis that has diaphragm are 35% and 50% lower than the mixed electrolysis that has no diaphragm. Adding NaCl that can produce active chlorine is good for improving the COD removal rate, compared to adding Na2SO4 electrolyte. Within the range of experiments ,the COD removing rate can be up to 94.65%. Current efficiency ICE decreases with the decrease of COD residual rate in fumarate wastewater. There is non-linear relationship between ICE and COD residual rate. The corresponding ICE is lower than 10%, after the COD removing rate is higher than 90%.
