Summary: | PROBLEM TO BE SOLVED: To efficiently and certainly perform a denitrification treatment of ammoniac nitrogen contained in wastewater and a decomposition treatment of hardly decomposable organic substance. SOLUTION: Ammonia or organic matter in a raw water D to be treated is decomposed and removed by a water purifying treatment system equipped with an electrolytic device 3 for electrolyzing the raw water to be treated using at least a halogen compound and an oxidant treatment device 4 for reducing and removing a hypohalogenous acid caused by electrolytic treatment, and the treated water obtained from the oxidant treatment device 4 can be denitrified biologically.
