本発明の排水浄化装置を形成した。(8) shows an underwater drainage channel for gray drainage from homes. The opening of the drainage channel (8) faces the river and is divided into two at the middle part of the drainage channel (8). A first diversion channel (8a) and a second diversion channel (8b) are formed, and in each of these diversion channels (8a) and (8b), the drainage purification device main body (1) and a water stop (11) are provided. The drainage purification device of the present invention was formed with a switching valve (10) interposed at the branch portion of these diversion channels (8a) (8b).
尚、（９）は前記排水路（８）の上流側に設けられて
いるスクリーンを示す。In addition, (9) shows a screen provided on the upstream side of the drainage channel (8).
次に本発明の排水浄化装置を用いた家庭からの雑排水
の処理方法について説明する。Next, a method of treating household wastewater using the wastewater purification device of the present invention will be described.
家庭からの雑排水は排水路（８）内を流れてスクリー

を経て、前記分水路（8a）又は（8b）において排水浄化
装置本体（１）により浄化され、止水せき（11）を経て
排水路（８）の下流側より河川へと排出される。Miscellaneous wastewater from the home flows through the drainage channel (8) to remove dirt and the like at the screen (9), and the switching valve (10)
Then, the water is purified by the drainage purification device main body (1) in the diversion channel (8a) or (8b), and discharged to the river from the downstream side of the drainage channel (8) through the water stop (11).
次に該排水浄化装置本体（１）による排水浄化作用に
ついて説明する。Next, the waste water purifying operation of the waste water purifying apparatus body (1) will be described.
今、切換バルブ（10）は、第１分水路（8a）に雑排水
を流し、第２分水路（8b）には雑排水の流入を停止して
いるものとする。Now, it is assumed that the switching valve (10) flows the gray water into the first water channel (8a) and stops the inflow of the gray water into the second water channel (8b).
第１分水路（8a）の下流には止水せき（11）があるの

浄化され、浄化した処理液は止水せき（11）をオーバー
フローして河川に流入する。Since there is a water stop (11) downstream of the first diversion channel (8a), the wastewater has a predetermined depth at the location of the wastewater purifier main body (1). It flows slowly while contacting the surface of each fiberboard (3) of 1) with a predetermined area, and the aerobic microorganisms adhere to each fiberboard (3) due to the contact of the miscellaneous wastewater, and the organic matter in the miscellaneous wastewater is removed. Propagating on each fiberboard (3) while decomposing, the resulting wastewater is purified, and the purified treated liquid overflows the water stop (11) and flows into the river.
ここでこれら各繊維板（３）は前述の如く大きな表面
積と大きな空間率を有するので剥離脱落する生物膜がな
く増殖する一方であるので雑排水の浄化は極めて良好で
ある。Here, since each of these fiberboards (3) has a large surface area and a large voidage as described above, it grows without a biofilm that peels and falls off, so that purification of gray water is extremely good.
この間、雑排水の流入を停止している第２分水路（8

速度が速くその後共喰いの速度が急激に低下し「種」の
生物が若干残っている状態になる。During this time, the second diversion channel (8
In b), the microorganisms in the activated sludge do not enter the feed sludge in the respective fiberboards (3) of the main body (1) of the drainage purification device in the diversion channel, and start to eat together. Is fast, and then the speed of the co-eating drops sharply, leaving some "seed" creatures.
ここで共喰いで減少するのは微生物が酸化状態で分解
し炭素が炭酸ガスに、水素が水に、又窒素が硝酸、亜硫
酸になり、更にこれら硝酸、亜硝酸が嫌気状態で還元し
て窒素ガスとなって排気除去されるものと考えられる。Here, the decrease by co-eating is that microorganisms are decomposed in an oxidized state and carbon is converted into carbon dioxide, hydrogen is converted into water, and nitrogen is converted into nitric acid and sulfurous acid. It is considered that the gas is exhausted and removed.
このようにして第２分水路（8b）内の排水浄化装置本
体（１）の各繊維板（３）に付着した活性汚泥量が減少
する。In this way, the amount of activated sludge attached to each fiberboard (3) of the main body (1) of the wastewater purification device in the second water channel (8b) is reduced.
そして、前記第１分水路（8a）内の排水浄化装置本体

性汚泥が付着した頃に、前記切換バルブ（10）を操作し
て排水を流す分水路を第１分水路（8a）から第２分水路
（8b）へ切換えを行なう。When the activated sludge having a thickness that does not peel off adheres to the respective fiberboards (3) of the main body (1) of the drainage purification device in the first water channel (8a), the switching valve (10) is turned off. The diversion channel through which drainage is operated is switched from the first diversion channel (8a) to the second diversion channel (8b).
このように分水路（8a）又は（8b）において雑排水の
浄化を行わせている間他方の分水路（8a）又は（8b）に

0）の切換によりこれらの作用を第１分水路（8a）及び
第２分水路（8b）において交互に実施させれば、断続的
な雑排水の浄化が可能となる。In this way, while purifying the gray water in the diversion channel (8a) or (8b), the flow of the gray water is stopped in the other diversion channel (8a) or (8b) by operating the switching valve (10). Then, the activated sludge is bitten as described above, and the switching valve (1
If these operations are alternately performed in the first water channel (8a) and the second water channel (8b) by the switching of (0), intermittent drainage can be purified.
