WATER PURIFICATION HIGH-LEVEL TREATMENT METHOD AND APPARATUS

摘要

[PROBLEMS] To provide a novel water purification method and apparatus with which while satisfactorily realizing the advantages of conventional water purification high-level treatment system, the occurrence of bromic acid can be eliminated to thereby supply safe good-taste water. [MEANS FOR SOLVING PROBLEMS] In one aspect, there is provided a method of water purification treatment characterized in that ozonization of water to be treated is followed by anaerobic biological treatment, optionally further by aerobic biological treatment. In another aspect, there is provided a water purification treatment apparatus characterized by including an ozonization unit for ozonizing water to be treated and an anaerobic biological treatment unit for performing anaerobic biological treatment of ozonized water optionally together with an aerobic biological treatment unit for performing aerobic biological treatment of water having undergone the anaerobic biological treatment.
