衛生用品溶解処理装置Ａの作動を図４のフローチャートを参照しながら説明する。
少なくとも一部がアルカリ水溶解性樹脂から成る衛生用品が、投入口２１ｂを介して溶解槽２の槽本体２１に投入され、ドア２１ａが閉じられ、衛生用品溶解処理装置Ａの図示しないスタートスイッチがＯＮされると（Ｓ１）、重量センサー２６の検知信号に基づいて、制御装置４が衛生用品の投入量を認識する。投入量が過少の場合には、制御装置４は、所定時間に亙って図示しない警報装置に警報を表示し、衛生用品の更なる投入を促す（Ｓ２〜Ｓ５）。 The operation of the sanitary product dissolution treatment apparatus A will be described with reference to the flowchart of FIG.
A sanitary product at least partially made of an alkaline water-soluble resin is introduced into the tank body 21 of the dissolution tank 2 through the inlet 21b, the door 21a is closed, and a start switch (not shown) of the sanitary article dissolution processing apparatus A is provided. When turned on (S1), the control device 4 recognizes the input amount of sanitary goods based on the detection signal of the weight sensor 26. When the input amount is too small, the control device 4 displays an alarm on an alarm device (not shown) for a predetermined time and prompts further input of sanitary goods (S2 to S5).

投入量が所定値に達していると、或いは警報の開始から所定時間が経過すると、制御装置４は、重量センサー２６の検知信号に基づいて衛生用品の投入量を認識し、予め記憶した衛生用品の投入量とアルカリ水のｐＨの適正値、アルカリ水の適正供給量、適正攪拌時間との相関データに基づいて、アルカリ水のｐＨと、アルカリ水の供給量と、攪拌時間の目標値を決定する。
制御装置４は、給水弁５を開いて電解装置１の電解槽１１に水道水を供給すると共に、水道水電気伝導度検知装置の検知信号に基づいて、水酸化物イオンの残存を抑制するｐＨ緩衝物質である炭酸（H2CO3）、炭酸水素イオン（HCO3-）の水道水中濃度を認識し、目標ｐＨのアルカリ水を生成するのに必要な目標電流値を算出し、目標値の電流を電解槽１１の電極板１２、１３間に流す（Ｓ６）。
制御装置４は、電気分解電流値決定サブルーチンを実施して目標電流値を決定する。通常の水道水の場合炭酸濃度は地域の如何に関わらず低く且つ略一定であることを勘案して、地域毎の電気伝導度と炭酸水素イオン濃度との相関データ、ひいては地域毎の電気伝導度とｐＨ緩衝物質濃度との相関データを、予め制御装置４に記憶させている。制御装置４は、水道水電気伝導度検知装置の検知信号を受信すると、前記相関データからｐＨ緩衝物質濃度を算出し、ｐＨ緩衝物質濃度が零の場合に目標ｐＨのアルカリ水を生成するのに必要な電流値と、ｐＨ緩衝物質により消費されるｐＨ干渉物質濃度に比例する濃度の水酸イオンを生成するのに必要な電流値との和を算出して、両者の和を目標電流値とする（Ｓ６１〜Ｓ６３）。電気伝導度は電極板間に印加する電圧と、電極板間に流れる電流値とから求めることができる。電極板として電解装置１の電極板１２、１３を利用しても良い。 When the input amount has reached a predetermined value or when a predetermined time has elapsed from the start of the alarm, the control device 4 recognizes the input amount of the sanitary product based on the detection signal of the weight sensor 26 and stores the sanitary product stored in advance. The target value of alkaline water pH, alkaline water supply amount, and agitation time is determined based on the correlation data between the amount of water introduced and the appropriate value of alkaline water pH, the appropriate amount of alkaline water supply, and the appropriate agitation time To do.
The control device 4 opens the water supply valve 5 to supply tap water to the electrolysis tank 11 of the electrolysis device 1 and suppresses the remaining hydroxide ions based on the detection signal of the tap water electrical conductivity detection device. a buffer substance carbonate (H2CO3), bicarbonate ion (HCO3 -) recognizes the tap water concentration, to calculate a target current value required to generate alkaline water target pH, the electrolytic cell the current target value 11 is passed between the electrode plates 12 and 13 (S6).
The control device 4 determines the target current value by executing the electrolytic current value determination subroutine. In the case of ordinary tap water, taking into account that the carbonic acid concentration is low and almost constant regardless of the region, correlation data between the electric conductivity of each region and the bicarbonate ion concentration, and consequently the electric conductivity of each region The correlation data between the pH buffer substance concentration and the control buffer 4 is stored in advance. When the control device 4 receives the detection signal of the tap water conductivity detection device, the control device 4 calculates the pH buffer substance concentration from the correlation data, and generates alkaline water having the target pH when the pH buffer substance concentration is zero. Calculate the sum of the required current value and the current value required to generate hydroxide ions at a concentration proportional to the pH interference concentration consumed by the pH buffer material, and use the sum as the target current value. (S61 to S63). The electrical conductivity can be obtained from the voltage applied between the electrode plates and the current value flowing between the electrode plates. You may utilize the electrode plates 12 and 13 of the electrolysis apparatus 1 as an electrode plate.

制御装置４は、アルカリ水供給弁２２を開いて、目標ｐＨ（ｐＨ９〜１０）の目標量のアルカリ水を、溶解槽２の槽本体２１に供給する（Ｓ７）。
電解槽１１で生成された酸性水は、酸性水排出管９と配管７とを介して、配管８に排出され、配管８を通って浄化槽５へ流入する。
制御装置は次に、目標時間ｔ０に亙って攪拌装置２５を作動させ、破砕装置２３によって衛生用品を破砕しつつ、衛生用品の破砕片とアルカリ水とを攪拌し、衛生用品の破砕片をアルカリ水に溶解させる（Ｓ８〜Ｓ９）。 The control device 4 opens the alkaline water supply valve 22 to supply a target amount of alkaline water having a target pH (pH 9 to 10) to the tank body 21 of the dissolution tank 2 (S7).
The acidic water generated in the electrolytic cell 11 is discharged to the pipe 8 through the acidic water discharge pipe 9 and the pipe 7 and flows into the septic tank 5 through the pipe 8.
Next, the control device operates the agitating device 25 over the target time t0, crushes the sanitary product with the crushing device 23, stirs the sanitary product fragment and the alkaline water, and removes the sanitary product fragment. Dissolve in alkaline water (S8-S9).

制御装置４は、攪拌開始からｔ０時間経過後に、溶解度検知装置２４の検知信号に基づいて衛生用品の溶解度を認識し、溶解度が所定値まで達すると、攪拌装置２５を停止させ、排水弁２９を開いて溶解水を溶解槽２から排出する（Ｓ１０〜Ｓ１２）。
衛生用品の畳み方、溶解槽２内での衛生用品の浮き方、衛生用品内の汚物の量等により衛生用品の溶解性は変化するので、目標ｐＨのアルカリ水を目標量使って目標時間に亙って攪拌しても、所望程度にまで衛生用品が溶解するとは限らない。従って、溶解状態を確認しながら攪拌を行うのが肝要である。衛生用品の溶解度が上昇すると溶解液の濁度が上昇するので、溶解液の濁度に基づいて衛生用品の溶解度を検知することができる。溶解液の濁度は、光の透過率から検知できるので、溶解度検知装置２４を用いて溶解度を検知することができる。
制御装置４は次に、溶解液圧送装置３のポンプを所定時間作動させて、衛生用品の溶解液を配管８に排出する（Ｓ１３）。溶解液は配管８を通って浄化槽５に流入する。
衛生用品の破砕片であって、溶解されなかった残存物は、フィルター２８により捕捉されるので溶解槽２からは排出されない。 The control device 4 recognizes the solubility of the sanitary product based on the detection signal of the solubility detection device 24 after elapse of t0 from the start of stirring, and when the solubility reaches a predetermined value, stops the stirring device 25 and sets the drain valve 29 to the drain valve 29. Open and discharge the dissolution water from the dissolution tank 2 (S10 to S12).
The solubility of the sanitary product changes depending on how the sanitary product is folded, how the sanitary product floats in the dissolution tank 2, and the amount of filth in the sanitary product. Even if stirred, the hygiene product does not always dissolve to the desired extent. Therefore, it is important to stir while confirming the dissolved state. When the solubility of the sanitary product increases, the turbidity of the solution increases, so that the solubility of the sanitary product can be detected based on the turbidity of the solution. Since the turbidity of the solution can be detected from the light transmittance, the solubility can be detected using the solubility detector 24.
Next, the control device 4 operates the pump of the solution feeding device 3 for a predetermined time to discharge the solution of the sanitary product to the pipe 8 (S13). The dissolved solution flows into the septic tank 5 through the pipe 8.
Since the sanitary crushed pieces that have not been dissolved are captured by the filter 28, they are not discharged from the dissolution tank 2.

制御装置４は次に、溶解槽洗浄サブルーチンを実施する。制御装置４は、アルカリ水給水弁２２を開いて所定量のアルカリ水を槽本体２１に供給し、所定時間ｔ１に亙って攪拌装置２５を作動させて槽本体２１の内部を洗浄し、槽本体２１の囲壁や破砕装置２３や攪拌装置２５に付着した未溶解物の残滓を洗い落とし、（Ｓ１４〜Ｓ１６）、攪拌装置２５を停止させた後排水弁２９を開き、溶解液圧送装置３のポンプを作動させて洗浄排水を配管８に排出する（Ｓ１７〜Ｓ１８）。洗浄排水は配管８を通って浄化槽５に流入する。 Next, the control device 4 executes a dissolution tank cleaning subroutine.
