たが、従来はその適当な手段がなかった。Therefore, in order to maintain the biofilm held on the surface of the carrier at an appropriate thickness, it is necessary to appropriately remove the biofilm, but conventionally there has been no suitable means for this purpose.
そこで本発明は逆洗作用を利用した、前記生物膜による
処理能力を長期間に亘って良好に維持できる浄化装置の
提供を目的とする。Therefore, an object of the present invention is to provide a purification device that utilizes backwashing action and can maintain the treatment capacity of the biofilm well over a long period of time.

の特徴としている。Means for Solving the Problems> In order to achieve the above object, the purification device of the present invention has a purification material holding a biofilm on the surface of the carrier held in the septic tank, and during purification operation, the water to be treated flows through the septic tank. A purification device in which the water to be treated passes from the top to the bottom and during backwash operation, the water to be treated passes from the bottom to the top in the septic tank, and the specific gravity of the carrier is configured to be slightly larger than 1.0. The first

好な処理能力を回復する。According to the first feature of the present invention, the specific gravity of the carrier is 1.0.
Since it is made larger, during purification operation, the carriers holding the biofilm are in close contact with each other to form a purification layer in the lower part of the septic tank, and the water to be treated passing through the purification layer is purified by the biofilm. On the other hand, by backwashing the septic tank from bottom to top at appropriate time intervals, during backwashing, carriers with a specific gravity slightly larger than 1.0 float up and are agitated by the water flow rising from below. and collide with each other,
It scrapes the biofilm on the surface and reduces its thickness. Therefore, the thickness of the biofilm is appropriately adjusted by backwashing, and good treatment capacity is restored.

Figure 3 shows backwash operation. FIGS. 4 to 6 are diagrams each showing an example of the shape of the carrier used.

理水から有機物等を生物膜が分離除去する。Inside the septic tank 5, a large number of purifying materials 6 are loaded on mesh plates 7 and the like. This purifying material 6 has a biofilm (not shown) held on the surface of a carrier 61 (see FIGS. 4 to 6) having a specific gravity slightly larger than 1.0. The biofilm is composed of lower plants such as algae that grow in water, and forms a biofilm by growing to cover the surface of the carrier 61. During purification operation, since the specific gravity of the carrier 61 is greater than 1.0, as shown in FIG. The biofilm separates and removes organic substances from the water to be treated that passes through the purification layer 8.

。If the biofilm becomes too thick, it may die due to lack of oxygen, accumulate dead bodies, or have poor processing capacity.
なお担体６１の比重は、例えば１．０〜２．０程度とし
、逆洗時の上昇水流の強さに応して適当な比重のものを
選ぶことになる。The specific gravity of the carrier 61 is, for example, about 1.0 to 2.0, and a suitable specific gravity is selected depending on the strength of the rising water flow during backwashing.

のに限定されないことは当然である。It is preferable that the carrier 61 has appropriate irregularities formed on its surface. This is to prevent all biofilms on the surface of the carrier 61 from being peeled off due to mutual collision of the purifying materials 6 during backwashing, thereby preventing the purifying effect from being unable to be exhibited during the subsequent purifying operation. By providing the unevenness, the biofilm remains at least in the depressions, and the remaining biofilm allows the biofilm to self-regenerate over the entire surface of the carrier. FIGS. 4 to 6 show examples of carriers 61 having irregularities formed on their surfaces. It goes without saying that examples of carriers having an uneven shape are not limited to those shown in FIGS. 4 to 6.

Since backwashing is carried out in the water flow direction in which the treated water is passed through and in the opposite direction, a purification layer is formed during purification, and the water to be treated can be effectively purified. Moreover, during backwashing, the purification materials thrown up by the water flow collide with each other, and the biofilm on the surface can be appropriately scraped off, thereby eliminating poor purification and other inconveniences caused by excessive biofilm growth. As a result, it is possible to realize a purification device using biofilm that can maintain good purification ability over a long period of time.

In addition to the effects of the configuration described in , the unevenness of the surface of the carrier prevents the biofilm on the surface of the carrier from being scraped off or peeled off to a state where it cannot be regenerated during backwashing. It is possible to ensure prompt regeneration of the biofilm and maintain stable purification ability.
