Abstract

An object is to provide a water treatment device which can treat for-treatment water containing fluorine components into a state adaptable to the environment and which can treat nitrogen compounds without influencing a concentration of the for-treatment water containing the nitrogen compounds. The water treatment device includes: a fluorine content removing unit to separate a substance to be removed from the for-treatment water in which the substance to be removed including a fluorine content is mixed; an electrochemical treatment unit including at least a pair of electrodes submerged at least partially in the for-treatment water, from which the substance to be removed has been separated, to perform a treatment by an electrochemical technique; and a biological treatment unit which biologically treats the water treated by the electrochemical technique.
