| titleOfInvention | Immersed electrochemical in-situ nutrient salt enrichment device and method for removing nutrient salt in surface water |
| abstract | An immersed electrochemical in-situ nutrient salt enrichment device and a method for removing nutrient salt in surface water relate to a nutrient salt enrichment device and a method. Aims to solve the problem of poor effect of treating nutritive salt by a chemical method and a biological method. The device consists of an anode chamber, a cathode chamber, a power supply, an anode, a cathode, an anion exchange membrane and a cation exchange membrane; one side wall of the anode chamber and the cathode chamber is an open opening and is respectively covered with an anion exchange membrane and a cation exchange membrane; the anion exchange membrane is arranged opposite to the cation exchange membrane. Immersing the anode chamber and the cathode chamber in nutrient salt polluted water, applying voltage, collecting concentrated phosphate and ammonium salt solutions obtained in the anode chamber and the cathode chamber, mixing, adding magnesium chloride, adjusting pH to generate struvite, and finally removing nutrient salt. The device can enrich the nutritive salt in the polluted water body in situ, the removal rate of ammonia nitrogen reaches more than 90%, and the removal rate of phosphorus reaches more than 89%. The method is suitable for removing the nutrient salt in the surface water. |
