以带式压滤机处理过的一次脱水污泥为研究对象，运用电渗透交变电场联合双氧化技术对污泥进行脱水，研究不同单因素条件对污泥深度脱水的影响。利用响应曲面法的Box-Benhnken中心组合设计对污泥脱水条件进行优化，分析了投药摩尔比n（CaO₂）∶n[（NH₄）₂S₂O₈]、电压梯度、时间比之间的交互作用，探究最佳工艺参数。单因素实验结果表明，当投药摩尔比为0.96∶1、电压梯度为13.76 V/cm、不等占空比为4.59∶1时，污泥含水率可降至53.99%。优化结果显示，回归模型可达到显著水平，在实验研究区域内拟合较好，模型的精确度、准确度及可信度均在可信范围内，并且各因素之间交互作用显著，可以真实地反映对污泥脱水效果的影响。

Taking the primary dewatering sludge treated by belt filter press as the research object,the effects of different signal factors on deep dewatering of sludge are systematically studied by means of electro-osmosis under alternating electric field combined with double oxidation technology.By means of the Box-Benhnken Center combination design of response surface method,the dewatering conditions for sludge is optimized,and the interaction among the dosage ratio of oxidation agents,voltage gradient and time ratio are analyzed to seek for the best process parameters.The single factor experiment results show that the moisture content of dewatered sludge can be reduced to 53.99% when the dosage ratio is 0.96：1,the voltage gradient is 13.76 V·cm^-1 and the unequal duty cycle is 4.59：1.The regression model can reach a significant level,which fits well in the experimental study area with a good precision,accuracy and reliability of the model in the feasible range.In addition,there is a significant interaction among various factors,which can truly reflect the effect on sludge dewatering.
