Zusammenfassung:Provided is a method for removing a fluorine-containing compound from discharge water including bringing discharge water containing two or more fluorine-containing compounds represented by the following general formula (1) or (2) into contact with an adsorbent to allow the adsorbent to adsorb the two or more fluorine-containing compounds:        General Formula (1):     (H-(CF2)m-COO)pM1wherein m is 3 to 19, M1 is H, a metal atom, NRb4, where Rb is the same or different and is H or an organic group having 1 to 10 carbon atoms, imidazolium optionally having a substituent, pyridinium optionally having a substituent, or phosphonium optionally having a substituent; and p is 1 or 2,        General Formula (2) :     (H-(CF2)n-SO3)qM2wherein n is 4 to 20; M2 is H, a metal atom, NRb4, where Rb is the same as above, imidazolium optionally having a substituent, pyridinium optionally having a substituent, or phosphonium optionally having a substituent; and q is 1 or 2.
