Semipermeable membrane filtering system for removing radionuclide using microalgae

摘要

The present invention relates to a semipermeable membrane filtering system for removing a radioactive substance by using microalgae. More particularly, the semipermeable membrane filtering system for removing the radioactive substance by using the microalgae includes: an accommodation portion for accommodating microalgae in which all or some part of the accommodation portion is disposed in radioactive contaminated water; the microalgae which is accommodated by the accommodation portion and eliminates a radionuclide from the radioactive contaminated water by absorbing the radionuclide; and a semipermeable membrane formed at the all or part of the accommodation portion to allow the radionuclide to pass through the membrane while preventing the microalgae from passing through the membrane. The radionuclide included in the radioactive contaminated water passes through the semipermeable membrane and reacts with the microalgae in order to be eliminated from the radioactive contaminated water, and the microalgae which absorbs the radionuclide is spatially separated by the accommodation portion, so that a large amount of the radioactive contaminated water is easily purified.
