Gas production during the electrochemical treatment of waste liquids has potential safety risks. Herein, hydrogen (H₂) production in such treatment was taken as the control target. Electrode combinations with relatively low H₂ production were selected for electrochemical treatment during a fracturing flowback fluid experiment, in which mesh-like titanium–based ordinary ruthenium–iridium–palladium-coated electrode was the anode and plate–like titanium–based ordinary ruthenium–iridium–palladium-coated electrode was the cathode. The effects of electrolysis time (t), electrolytic current (I), electrode spacing (D), and other factors on H₂ production in the electrolytic process were investigated. On the basis of the experimental data, a model was established using the support vector machine (SVM) method. Firstly, the three parameters of the radial basis function kernel of the model were simultaneously optimized using the quantum–particle swarm optimization algorithm as follows: penalty parameter = 256, kernel parameter = 0.0097039, and loss parameter = 0.014928. Then, an SVM regression model was established according to the three optimal parameters. The correlation coefficient was 0.98291 (r = 0.9914), and the mean–square error was 1.1883. The regression model was used to predict the technological conditions (t, I, and D) for the maximum/minimum H₂ production in the electrochemical treatment of fracturing flowback fluid. The values were t = 50 min, I = 1.5 A, and D = 2.0 cm for the maximum H₂ production, and t = 30 min, I = 0.5 A, and D = 6.0 cm for the minimum H₂ production. Under these process conditions, the predicted maximum/minimum H₂ production volumes were 145.04 and 20.47 mL, respectively.

废液的电化学处理过程中产生的气体具有潜在的安全隐患。在此，以该处理中的氢（H ₂）生成为控制对象。在压裂返排流体实验中，选择了H ₂生成量相对较低的电极组合进行电化学处理，在该实验中，网状的钛基普通钌-铱-钯涂层电极为阳极，板状的钛基普通钌-电极为阳极。铱钯涂层电极为阴极。电解时间（t），电解电流（I），电极间距（D）和其他因素对H _2的影响电解过程中的生产进行了调查。根据实验数据，使用支持向量机（SVM）方法建立模型。首先，使用量子粒子群优化算法同时优化模型的径向基函数核的三个参数：惩罚参数= 256，核参数= 0.0097039，损失参数= 0.014928。然后，根据三个最优参数建立了支持向量机回归模型。相关系数为0.98291（r = 0.9914），均方误差为1.1883。回归模型用于预测最大/最小H ₂的工艺条件（t，I和D）生产中的电化学处理压裂返排液。的值分别为吨= 50分钟，我= 1.5 A，和d = 2.0厘米为极大值h ₂的生产，和吨= 30分钟，我= 0.5 A，和d = 6.0Hz厘米为h最小₂的生产。在这些工艺条件下，预测的最大/最小H ₂产量分别为145.04和20.47 mL。
