摘要:The phosphorus resources in our country have accounted for second of the whole world, but it is predicted that the recoverable phosphorus resources can only be supplied by 2020. However sewage only account for about 1~ 2% in the entire volume of sewage waste, sewage contains 90% phosphorus.Electrolysis is a promising technology for simulated urine treatment,with adding magnesium source.In this way,it doesn't have secondary pollution in case of recovery of phosphorus, while reducing the pressure on sewage treatment plant. Results show that the electrochemical recovery of phosphorus in urine is feasible, the phosphorus recovery rate increases over time. The velocity ratio and the magnesium source storage loading position can enhance the conversion capacity of magnesium to Mg2+, promote recycling of phosphorus, when flow ratio of cathode and anode water is 58:1, the recovery rate of phosphorus in the cathode is 70% above, the recovery rate of anode is more than 90%.
