INFECTIOUS DRAIN WATER TREATMENT SYSTEM

To provide a sterilization device for a drain pipe capable of disinfecting and sterilizing efficiently, a drain pipe of sanitary equipment, and a drain water treatment system.SOLUTION: A sterilization device for a drain pipe of sanitary equipment comprises: a washing tank; a toilet bowl being the sanitary equipment; and the drain pipe coupled to the toilet bowl. In use of the sanitary equipment, a constant amount of washing water is supplied from the washing tank to the toilet bowl, and the washing water which washed the toilet bowl is discharged from the drain pipe, in the sterilization device for the drain pipe of the sanitary equipment. The sterilization device for the drain pipe of the sanitary equipment comprises: a feeding pipe for feeding the constant amount of water corresponding to the amount of the washing water supplied to the toilet bowl from the washing tank, from a water feeding system; a sensor for detecting water feeding to the washing tank; a chemical liquid tank storing chlorine dioxide with constant concentration; a chemical liquid pump for supplying a constant amount of the chemical liquid to the washing tank from the chemical liquid tank; and a control part for actuating the chemical liquid pump by a sensing signal of the water feeding from the sensor, supplying the constant amount of the chlorine dioxide to the washing tank, and keeping concentration of the chlorine dioxide in the washing water in the washing tank at constant concentration.SELECTED DRAWING: Figure 1 【課題】衛生設備の排水管を効果的に殺菌消毒することができる排水管の消毒装置および排水処理システムを提供する。【解決手段】洗浄タンクと、衛生設備である便器と、該便器に接続される排水管と、を備え、前記衛生設備の使用時に、前記洗浄タンクから定量の洗浄水が前記便器に供給され、前記便器を洗浄した洗浄水が前記排水管から排水される衛生設備の排水管の消毒装置であって、前記洗浄タンクから前記便器に供給された洗浄水の量に対応する定量の水を給水系から補給する補給配管と、前記洗浄タンクへの給水を感知するセンサと、一定濃度の二酸化塩素を貯留する薬液タンクと、前記薬液タンクから一定量の薬液を洗浄タンクに供給する薬液ポンプと、前記センサからの給水の感知信号によって前記薬液ポンプを作動し、洗浄タンクに定量の二酸化塩素を供給し、前記洗浄タンク内の洗浄水の二酸化塩素濃度を一定濃度に保持する制御部とを、備えている。【選択図】図１
