Zusammenfassung:To provide a neutralization unit which can be easily installed, does not require large scale construction, does not require dedicated installation work, and can perform neutralization to drainage of a dialysis system so that a pH of the drainage falls in a range of sewer standard without a neutralizer.SOLUTION: There is provided a neutralization unit for washing drainage which is discharged in a washing step of each dialyzer, and the neutralization unit comprises: a storage tank which has volume being once or twice of volume of washing drainage discharged in a once washing step; determining means for determining a kind of the washing drainage or dialysis drainage discharged from the dialyzer on an upstream side of the storage tank; a discharge line for discharging the washing drainage from the storage tank; a bypass line including a bypass valve for discharging the washing drainage or the dialysis drainage without through the storage tank; and injecting means for injecting to the bypass line, the washing drainage stored in the storage tank.SELECTED DRAWING: Figure 1 【課題】容易に設置でき、大掛かりな工事も必要とせず、専門性を有する設置作業が不要で、さらに中和剤を用いることなく下水道基準の範囲内となるように透析システムの排液を中和処理できる中和ユニットを提供する。【解決手段】 個々の透析装置の洗浄工程において排出される洗浄排液の中和ユニットであって、一台の透析装置の、一回の洗浄工程で排出される洗浄排液の1~2倍の容積を有する貯留槽と、前記貯留槽の上流で前記透析装置から排出される前記洗浄排液または透析排液の種類を判定する判定手段と、前記貯留槽から前記洗浄排液を放流するための放流ラインと、前記貯留槽を介さずに前記洗浄排液または前記透析排液を放流するためのバイパス弁を含むバイパスラインと、前記貯留槽内に貯留された前記洗浄排液を、前記バイパスラインに注入する注入手段と、を備えていることを特徴とする中和ユニット。【選択図】図1
