SEWAGE DRAINING METHOD AND SEWAGE PURIFICATION SYSTEM
PROBLEM TO BE SOLVED: To further improve reliability of discharging purified treatment water securing a discharge allowable quality into a natural environment water area.SOLUTION: In taking in and purifying sewage discharged from a facility using pure water, a water quality control parameter which is used in discharge allowable quality determination is measured on the sewage purified in an annex purification facility by an index instrument, and the purified sewage is discharged into a natural environment water area when the measured water quality control parameter satisfies the water quality control parameter. When the measured water quality control parameter does not satisfy the water quality control parameter, discharge into a natural environment water area is stopped by a water channel changing valve in a downstream side of the index instrument, and the purified sewage is fed into a public sewage channel reaching a sewage purification treatment facility from the water channel changing valve or is circulated to the annex purification facility from the water channel changing valve.SELECTED DRAWING: Figure 1
【課題】放流許容水質を担保した浄化処理水を自然環境水域に放出することの信頼性をより高める。【解決手段】上水使用施設から排出される下水を取水して浄化するに当たり、放流許容水質判断に用いられる水質管理パラメータを付属浄化施設で浄化済み下水について指標計測器で計測し、計測水質管理パラメータが水質管理パラメータを満たす状況では、浄化済みの下水を自然環境水域に排出する。計測水質管理パラメータが水質管理パラメータを満たさない状況下においては、指標計測器より下流の流路切換弁により自然環境水域への排出を停止すると共に、浄化済み下水を、下水浄化処理施設に到る公共下水流路に流路切換弁から送り込む、または流路切換弁から付属浄化施設に循環させる。【選択図】図１
