Electro-Fenton (EF) coupled with Pulsed alternating current coagulation (PACC) is an effective technology for the treatment of Cu²⁺-organic wastewater. In this study, the removal efficiency (R_e), electrical energy consumption (EEC) and removal mechanism of Cu²⁺-organic were analyzed and the optimal operation parameters were determined. SEM, EDS, XRD and FTIR were used to characterize the morphology, elemental composition, crystal structure, function groups of sludge produced in the EF-PACC. UV, ESR and GC-MS were employed to determine concentration of organic matter, existence of OH, middle products of decomposed organic matter in EF-PACC, respectively. The results show that under the optimal conditions of initial pH = 2.5, current density (j) = 2 A/m², initial c(Cu²⁺) = 50 mg/L, c(chemical oxygen demand, COD) = 500 mg/L, c[H₂O₂] = 10 mL/L, frequency (f) = 1 Hz, t = 20 min, the R_e(Cu²⁺) can reach 99.59%. R_e(COD) is 90.21%, EEC 1.695 × 10⁻¹ kWh/m³, and the amount of produced sludge (W_s) is 0.9283 kg/m³. Compared with single EF and PACC processes, the order of treatment efficiency is EF-PACC > EF > PACC. EF-PACC technique was a highly effective method in the treatment of Cu²⁺-organic compound wastewater. The EF-PACC coupled process includes that electrolyzed Fe³⁺ produces electrocoagulation and OH produces degradation of organic compounds. The combined action of the two effects can effectively remove Cu²⁺-organic from wastewater.

电芬顿（EF）结合脉冲交流电凝聚（PACC）是一种有效的技术，用于处理Cu ²⁺有机废水。本研究分析了Cu 2 ⁺ -有机物的去除效率（R _e），电能消耗（EEC）和去除机理，并确定了最佳操作参数。用SEM，EDS，XRD和FTIR表征了EF-PACC中产生的污泥的形态，元素组成，晶体结构，官能团。用紫外线，电喷雾和GC-MS测定有机物的浓度，是否存在有机物。OH，分别是EF-PACC中分解的有机物的中间产物。结果表明，在初始pH = 2.5的最佳条件下，电流密度（j）= 2 A / m ²，初始c（Cu 2 ⁺）= 50 mg / L，c（化学需氧量，COD）= 500 mg / L，c [H ₂ O ₂ ] = 10 mL / L，频率（f）= 1 Hz，t  = 20分钟，R _e（Cu ²⁺）可以达到99.59％。R _e（COD）为90.21％，EEC 1.695×10 ^{− 1}  kWh / m ³产生的污泥量（W _s）为0.9283 kg / m ³。与单个EF和PACC工艺相比，处理效率的顺序为EF-PACC> EF> PACC。EF-PACC技术是一种用于处理Cu ²⁺有机化合物废水的高效方法。EF-PACC耦合过程包括电解的Fe ³⁺产生电凝，而OH产生有机化合物的降解。两种作用的共同作用可以有效地去除废水中的Cu ²⁺有机。
