ELECTRODIALYZER, WASTE WATER TREATMENT METHOD, AND FLUORINE TREATMENT SYSTEM

摘要

This invention provides an electrodialyzer comprising an anode chamber (10) having an anode (2) and a cathode chamber (50) having a cathode (3). The electrodialyzer further comprises a desalination chamber (40) for removing fluorine ions from fed waste water to produce treated water, a concentration chamber (30) for concentrating fluorine ions contained in the waste water moved from the desalination chamber (40) to produce concentrated water, and a buffer chamber (20) for blocking the fluorine ions in the waste water so that the fluorine ions in the waste water does not flow from the concentration chamber (30) directly into the anode chamber (10). The electrodialyzer further comprises a path for feeding pure water into the anode chamber (10) and a path for feeding water discharged from the anode chamber (10) into the buffer chamber (20).
