Abstract：A water quality enhancement technology applicable to engineering was explored,based on the principle of electrochemical electrocatalytic oxidation for the degradation of organic pollutants.Through the reaction between iron and phosphate ions to generate insoluble iron phosphate precipitates,phosphorus was efficiently removed from the water body,inhibiting its subsequent release.Simultaneously,relying on mechanisms such as charge adsorption and flocculation-sedimentation,multiple pollutants were synergistically removed to achieve effective solid-liquid separation.Adopting a tubular electrocoagulation process,pollutant removal was intensified within a short timeframe.Wastewater flowed through the narrow space between positive and negative electrodes,significantly improving reaction efficiency and reducing dead zones,thereby maximizing water purification to meet relevant standards.With an electrode reaction section length of only 3.5 m,the phosphorus removal capacity of a single electrode reached 5-8 m³/h,meeting most rural sewage treatment demands and effectively resolving issues regarding site limitations and system expansion.Furthermore,the system achieved controllable intermittent operation based on peak and valley water usage,featuring high automation and minimal human intervention,demonstrating promising engineering application prospects.
