一种基于脱硫脱氮的污水处理方法
By employing a multi-stage synergistic process involving magnetic flocculation-electrocatalytic pretreatment, simultaneous desulfurization and denitrification in a three-dimensional electrode fluidized bed, deep denitrification and phosphorus removal in a denitrification filter, and ozone catalytic oxidation-membrane separation, the problem of separation between electrocatalytic oxidation and microbial degradation has been solved. This process achieves efficient removal and resource recovery of sulfides, total nitrogen, total phosphorus, and chemical oxygen demand in wastewater, ensuring that the effluent quality consistently meets standards.

Abstract
本发明涉及污水处理领域，公开了一种基于脱硫脱氮的污水处理方法，包括以下步骤：S1、磁絮凝‑电催化预处理，污水经磁絮凝反应器投加聚合氯化铝‑磁粉复合絮凝剂，形成磁性絮体后通过永磁分离装置去除悬浮物，随后进入电催化氧化池，以钛基二氧化铅为阳极、活性炭纤维为阴极进行电解；S2、三维电极流化床同步脱硫脱氮，预处理出水进入三维电极流化床反应器，填充活性炭颗粒作为第三电极，投加硫化细菌与反硝化细菌复合菌群。通过磁絮凝‑电催化预处理、三维电极流化床同步脱硫脱氮、反硝化滤池深度脱氮除磷以及臭氧催化氧化‑膜分离联合深度处理的多级协同工艺，实现了对污水中硫化物、总氮、总磷及化学需氧量的高效去除。
