摘要

采用铝电极，对电絮凝法去除磷离子34 (PO -P)−的效率进行了分析。研究的重点是通过反应器的流量、外加电流密度和反应器体积的影响。反应器运行90 min后，初始34 (PO -P)−浓度降低90%。此外，开发了电絮凝法去除34 PO -P−的三维数值模型，该模型包括磷酸盐在混凝/絮凝颗粒上的吸附和解吸过程以及颗粒沉降过程。数值模型参数化依赖于实验结果。

Physical and numerical model of electrocoagulation process with aluminum electrodes for phosphate removal

The efficiency of the electrocoagulation process for the removal of phosphate ions 34 (PO -P) − has been analyzed using a batch full-scale reactor with aluminum electrodes. The effects of the flow rate through the reactor applied current density, and reactor volume were the focus of the study. The initial 34 (PO -P) − concentration was reduced by 90% after 90 min of reactor operation time. Additionally, a three-dimensional numerical model for 34 PO -P − removal via the electrocoagulation process is devel-oped that includes the processes of phosphate adsorption and desorption on coagulated/flocculated particles, along with particles settling. Numerical model parametrization relies on the results from the experiments.
