Summary:To provide a non-water supply, non-discharge circulating flush toilet system that is excellent in purifying wastewater discharged from a toilet bowl and is suitable for completely biodegrading such wastewater to obtain reusable water.SOLUTION: In a non-water supply, non-discharge circulating flush toilet system S, a pre-treatment section 2 includes a hydroxyl radical tank 202, and a post-treatment section 3 includes a first reaction tank 301. In the hydroxyl radical tank 202, oil contained in treated water is decomposed by hydroradicals. Therefore, in the first reaction tank 301. such oil does not accumulate in porous cedar wood chips, nor does it inhibit an activity of microorganisms due to a formation of an oil film in pores that make up the pores of the cedar wood chips. Therefore, biodegradation by aerobic and anaerobic microorganisms is promoted.SELECTED DRAWING: Figure 1 【課題】便器から排出される汚水の浄化に優れ、かかる汚水を完全に生分解して再利用可能な水を得るのに好適な、無給水無放流循環式水洗トイレシステムを提供する。【解決手段】無給水無放流循環式水洗トイレシステムSにおいて、前処理部2にはヒドロキシラジカル槽202が設けられ、後処理部3には第1の反応槽301が設けられる。ヒドロキシラジカル槽202では、処理水中に含まれている油分をヒドロラジカルによって分解しているので、第1の反応槽301では、そのような油分が多孔質体である杉木材チップに溜まったり、杉木材チップの多孔質を構成する多孔に油分の膜が形成されることで微生物の働きを阻害したりすることは無く、好気性微生物および嫌気性微生物による生分解が促進される。【選択図】図1
