Electrochemical Separation of Nitrogen and Phosphorus in Urine

摘要: 本文采用电化学法与钛镁腐蚀电池组合工艺循环处理模拟尿液。考察电压、阴阳极出水比例对处理效果的影响，优化回收模拟尿液中的氮和磷的条件。结果表明：当电压为18 V，阳极出水：阴极出水为3:1；氨氮随循环时间先降后升；磷随时间逐渐下降。将钛镁腐蚀电池上的白色物质收集，进行X衍射光谱及扫描电镜分析，其中含有磷酸铵镁。

Abstract: In this paper, the simulated urine was treated by the combination of electrochemical method and titanium magnesium corrosion cell. The influence of voltage, the ratio of water to cathode and cathode on the treatment effect was investigated, and the conditions of optimizing the recovery of nitrogen and phosphorus in simulated urine were investigated. Results show that when the voltage is 18 V, the ratio of anode water and cathode discharge is 3:1; the cycle time of ammonia nitrogen first falls and then rises; the phosphorus gradually reduced with time. To collect the white material on the titanium magnesium corrosion cell, and the X-ray diffraction and scanning electron microscopy analysis were performed, which contained magnesium phosphate.
