WATER TREATMENT DEVICE, WATER TREATMENT SYSTEM AND WATER TREATMENT METHOD
To provide a low-cost water treatment device that can stably suppress a generation of hydrogen sulfide during a normal operation.SOLUTION: There is provided a water treatment device that dissolves oxygen-containing gas in a sewage supplied to a drain tank and discharges it as high-concentration oxygen-containing water from a discharge pipe, including: a mixing device that mixes oxygen-containing gas with sewage to make a fine bubble-containing liquid; a liquid supply device that supplies the sewage to the mixing device and the discharge pipe via a drain pipe; and a gas supply device that supplies the oxygen-containing gas to the mixing device, in which an arrangement of the mixing device satisfies the following arrangement 1 or arrangement 2. Arrangement 1: the mixing device is arranged between the drain pipe and the discharge pipe, and the fine bubble-containing liquid is discharged from the discharge pipe as the high-concentration oxygen-containing water. Arrangement 2: the mixing device is arranged in a return flow path branching from the drain pipe, and the fine bubble-containing liquid is returned to the drain tank.SELECTED DRAWING: Figure 1
【課題】通常運転しながら硫化水素の発生を安定して抑制でき、低コストである水処理装置の提供。【解決手段】排水槽に供給される汚水に酸素含有ガスを溶解させて高濃度酸素含有水として吐出管から排出するための水処理装置であって、汚水に酸素含有ガスを混合してファインバブル含有液とする混合装置と、排水管を介して汚水を混合装置および吐出管に供給する液体供給装置と、酸素含有ガスを混合装置に供給する気体供給装置とを備え、混合装置の配置が下記配置１または配置２を満たす、水処理装置；配置１：混合装置が排水管と吐出管との間に配置されて、ファインバブル含有液が高濃度酸素含有水として吐出管から排出される；配置２：混合装置が排水管から分岐する返送流路に配置されて、ファインバブル含有液が排水槽に返送される。【選択図】図１
