理水槽７に通ずる処理水配管８が連なっている。The present invention will be described with reference to a configuration explanatory view showing one embodiment thereof. In FIG.
A raw water inlet 3 connected to the raw water inflow pipe 2 is provided in the upper part, and a water collecting chamber 5 covered with a perforated plate 4 is formed in the bottom of the tank 1, and the treated water outlet 6 is provided in the water collecting chamber 5. Is provided and the treated water pipe 8 leading to the treated water tank 7 is connected.

とは適宜箇所をホック等で止めて取り外し可能とする。An upper stopper 9 is arranged above the tank 1 so that the sponge layer 1 is substantially horizontal between the upper stopper 9 and the perforated plate 4.
0 and 10 'are stacked and packed in multiple stages. The upper stopper 9 disposed in the upper portion of the tank 1 is for preventing the outflow of the sponge layer and maintaining the filled state of the sponge layer, and the upper stopper 9 is disposed substantially along the inner wall of the tank 1. If it is installed horizontally and the tank 1 is circular, it will be shaped like a ring.
Means that it can be removed by appropriately hooking it in place.
一方、槽１内下部に設けられた多孔板４は、スポンジ層
全体の支持と、逆洗水や逆洗用空気等の均等分配を目的
としたものである。On the other hand, the porous plate 4 provided in the lower portion of the tank 1 is intended to support the entire sponge layer and to evenly distribute backwash water, air for backwash and the like.

も可能となる。The sponge layers 10 and 10 'are formed to have the same shape as the horizontal cross-sectional shape of the tank 1 and to have an appropriate thickness, and these are laminated in multiple stages, and the uppermost sponge layer 10' is replaceably attached. In this way, by forming the sponge layers 10 and 10 'in the horizontal cross-section of the tank 1, all the excess space (the part that captures SS in raw water) becomes a hole part in the sponge layer. Compared with the space (gap) between the material particles, the overspace is remarkably expanded, and ideal volume excess is possible, and the overperformance is improved. In particular, when a sponge layer having a porosity of 95% or more is used, the effect is further improved. Further, since the sponge is formed in a layered form, the compressive strength is increased as compared with the case where the sponge is finely cut and filled in the tank 1, and the sponge itself is not compressed during processing or backwashing. Treated water is stably obtained, and reliable backwashing is possible.

スポンジ層１０′の交換時期は、通水速度（ＬＶ）によ
って異なるが、初期抗が500mmH2O程度以上に上昇した
時点を目安に交換することが好ましい。Depending on the type of raw water to be passed, the raw water may contain contaminants such as sand and hair that, once trapped in the pores of the sponge layer, will not easily go out even after repeated normal backwashing. Often. Such contaminants do not go deep into the sponge layer, and are 10 to 50% from the top surface of the sponge layer.
Often stays within mm. Therefore, in the long-time operation by the downward flow, a large amount of such impurities are trapped in the uppermost sponge layer 10 ′, and the over resistance is significantly increased.
It will adversely affect overperformance. In such a case, the sponge layer is not entirely replaced, but only the topmost sponge layer 10 ', which is markedly contaminated, is replaced.
The overperformance can be completely restored. The replacement time of the uppermost sponge layer 10 'varies depending on the water flow rate (LV), but it is preferable to replace it when the initial resistance rises to about 500 mmH 2 O or more.
ところで、スポンジ層１０，１０′の具体的な積層方法
は次の様にすることができる。By the way, a specific laminating method of the sponge layers 10 and 10 'can be performed as follows.
即ち、第２図に示すように、各層共に孔数及び厚さを同
一としたものを積層すれば、原水に硫酸ばん土あるいは

の１枚当りの厚さは50〜100mm程度でよい。That is, as shown in FIG. 2, stacking layers having the same number of holes and the same thickness for each layer is effective when coagulating excessively by adding a sulphate or polymer to the raw water. This is because particles tend to be uniformly trapped in the sponge. Sponge layer 10, 10 'at this time
The thickness of each sheet may be about 50 to 100 mm.
なお、スポンジ層１０，１０′としては、厚さ10〜30mm
程度のスポンジをロール状に巻いて円筒状にしたものを
組み合わせて形成することもできる。The sponge layers 10 and 10 'have a thickness of 10 to 30 mm.
It is also possible to form a sponge of a certain degree by winding it into a roll and combining it into a cylindrical shape.
また、汚染のひどい最上段のスポンジ層１０′を交替す

る。Further, when replacing the uppermost sponge layer 10 'which is highly contaminated, the front portions of the sponge layers 10', 10 are once taken out, and the uppermost sponge layer 10 'is discarded.
A new product is introduced below the lowermost sponge layer, and the sponge layer that was the second stage up to then is inserted into the mold of the uppermost cartridge for use. This exchange operation is easy because the sponge layer is easier to handle than the conventional materials such as anthracite and sand that are used in excess.
さらに、槽１には逆洗機構を付設するもよく、逆洗機構

とができる。Further, the tank 1 may be provided with a backwash mechanism. As the backwash mechanism, as shown in FIG. 1, the treated water is pumped from the treated water tank 7 to the water collecting chamber 5 in the tank 1 by the washing pump 11. The drain port 1 for backwash drainage in which the drain pipe 12 is connected to the upper part of the tank 1
3 is provided. Further, if the air is blown into the water collecting chamber 5 into which the treated water is pumped by the air blower 14 through the air washing pipe 15, the back washing can be performed more effectively.
しかして、原水は原水流入管２から原水流入口３を経て

ち、必要箇所へ導かれる。Then, the raw water is introduced from the raw water inflow pipe 2 through the raw water inlet 3 into the tank 1, and the raw water flows through the sponge layers 10 ', 10 which are stacked in multiple stages. At that time, SS in the raw water is captured by the sponge layers 10 ′, 10 and the raw water is clarified and becomes treated water to reach the water collection chamber 5, and then to the treated water tank 7 from the treated water outlet 6 through the treated water pipe 8. After being stored once, it will be led to the necessary location.

る。If such an excess is continued for a long time, the resistance increases or SS starts to leak into the treated water in some cases, as in the case of the conventional excess device. In such a case, backwashing is performed by temporarily suspending the excess. The backwashing method is extremely simple. First, the water washing pump 11 is operated, and in some cases, the air washing blower 14 is simultaneously operated, simultaneous washing with water and air is performed for about 3 minutes, and then the air washing blower 14 is stopped. It is sufficient to wash with water only for about 1 minute, and immediately after that, stable treated water quality can be obtained.
逆洗速度は、水、空気共に0.5〜１m3／m2．分程度で十

となる。The backwash speed is 0.5 to 1 m 3 / m 2 for both water and air. About a minute is sufficient, and the backwash drainage is discharged from the discharge port 13 to the outside of the system through the drainage pipe 12. If the discharge port 13 is opened as close to the surface of the uppermost sponge layer 10 'as possible, the backwash drainage can be efficiently discharged, and the backwash can be performed in a short time.

この使い古したスポンジ層の交換作業は、容易かつ迅速
に行われることは容易に理解されよう。The sponge layers 10 and 10 ′ are particularly contaminated by the sponge layer 10 ′ at the uppermost stage due to long-term use or the type of raw water, and when the performance cannot be recovered even by backwashing, the sponge layer, especially at the uppermost stage. It is necessary to replace the sponge layer 10 '. At that time, the upper stopper 9 is removed and the uppermost sponge layer 10 'is taken out and replaced with a new one, or all the sponge layers 10 and 10' are taken out and the sponge layer 10 'is discarded and a new one is taken. Put the sponge layer at the bottom, the second layer from the top until then,
After fixing with the upper stopper 9, the above steps are repeated again.
It will be readily appreciated that this spent sponge layer replacement operation is both easy and quick.

ない。Further, if the sponge layer used has a high porosity, for example, a porosity of 95% or more, the overresistance is about 100 to 300 mmH 2 O even at LV of 20 m / h or more. It can be easily processed by a simple gravity method. However, if residual pressure is required, there is no problem even if the pressure method is used.
次に本発明の実施例を示す。 Next, examples of the present invention will be described.
槽内寸法：直径400mm×高さ800mm スポンジ層全体の厚さ： ５００mm スポンジ積層方法： 直径400mm×高さ50mmの円筒型 スポンジ層を１０段積層 スポンジ孔数：３０〜５０個／２５mm スポンジ材質：ポリウレタンフォーム スポンジ空孔率：９８％ 上記仕様において、河川水を直接処理した処理条件と処

In this way, as a result of high-speed treatment of high-concentration raw water, the amount of captured SS is 10 to 15 kg / over area.
The value was m 2 , which was 10 times or more that of the conventional over-apparatus. As a result, the amount of backwash water was very small, less than 2% of the amount of treated water.
また、上記運転期間内では最上段のスポンジの交換は６
ケ月に１回程度で十分であった。Also, during the above operation period, the replacement of the top sponge is 6
About once a month was enough.

By using the same shape as the cross-sectional shape, the compressive strength increases, the sponge itself is not compressed during treatment and backwashing, stable treated water quality is obtained and reliable backwashing is possible, and the treatment It is a downward flow type, and sponge layers of the same thickness are stacked in multiple layers, and the uppermost sponge layer is replaceably attached as a cartridge type, and the uppermost sponge layer is replaced with the next sponge layer. Then
Because a new sponge layer was inserted under the bottom sponge layer to replace each sponge layer in sequence,
Even if impurities that cannot be recovered enter the inside of the sponge layer by backwashing, it can be replaced with a new one to easily recover the overperformance, and the entire sponge layer can be effectively used. Has an extremely beneficial effect.
