担体の製造方法に関するものである。[Detailed Description of the Invention] Industrial Fields of Use The present invention is applicable to water supply, sewage, living spaces, and ornamental water. Concerning a method for producing microbial carriers used for water purification such as If,
More specifically, the present invention relates to a method for producing a microbial carrier having many pores on its surface and inside.

００号に見られるように、 いわゆるシリカ・アルミナ
系の担体が多くみられる。Conventional technology Conventionally, microorganism carriers used for water purification include those using organic material neo such as plastic as seen in JP-A No. 59-123E596, and those using organic material neo such as plastic as seen in JP-A-59-123E596.
As seen in No. 00, so-called silica-alumina carriers are often seen.

特殊な形状をとっていた。These plastic or silica/alumina carriers have smooth surfaces, so in order to increase the surface area, they have been provided with irregularities such as grooves, or have a special shape such as a saddle shape.
発明が解決しようとする問題点
ところがこのように成形しても担体内部の気孔は、増え

工夫する必要があった。Problems to be Solved by the Invention However, even with this molding, the number of pores inside the carrier does not increase, and in order to increase the surface area in this way, it is necessary to devise a molding device.

を見いだした。Means for Solving the Problems The inventors of the present invention have solved these problems. When molding raw materials of inorganic materials, we discovered that it is possible to mold the raw materials while leaving pores in the raw materials, without degassing the vacuum extrusion molding machine that is normally used to mold and compact ceramic quality products. Ta.

、混練し、 該原料な脱気を行わず成形。That is, one or two types of inorganic materials such as fly ash, shirasu, silica sand, and clay are mixed and kneaded with a pore-forming material if necessary, and the raw materials are molded without degassing.
乾燥、焼成してなる微生物担体の製造方法である。This is a method for producing microbial carriers by drying and baking.
なお、気孔形成ネオは気孔の総数を多くする必要のある
ときに用いればよい。Note that pore-forming neo may be used when it is necessary to increase the total number of pores.

孔と成るわけである。Function: In the present invention, the raw materials are simply kneaded and molded without vacuum degassing, so the air that is drawn into the material during kneading leaves the molded carrier element with pores inside the mold. These pores that are formed remain after firing and become pores inside the carrier.
発明の効果
本発明は、以上のように無機質原料を混練Ｉ７、脱気を

の担体としてまことに好適なもＩのである。Effects of the Invention In the present invention, as described above, the inorganic raw materials are kneaded (I7) and molded without degassing, so that it is possible to mold a carrier with many pores inside the carrier. In addition, since the raw material itself does not undergo vacuum greasiness, the surface of the molded carrier has poor adhesion and is molded in a dry state, making it possible to obtain a carrier with a large surface area, making it truly suitable as a carrier for microorganisms. It is I's.
次に、本発明の実施例を図面を基に説明する実施例１
第１図は本実施例で使用する押出成形機１である。この
押出成形機１は、通常の押出成形機と同様の物でよい。Next, Example 1 of the present invention will be explained based on the drawings. FIG. 1 shows an extrusion molding machine 1 used in this example. This extrusion molding machine 1 may be similar to a normal extrusion molding machine.

１の口金６側先端にはカッター７を設けてあり、一定時
間毎にカッター７が作動し押し出し成形品を成形する。The extrusion molding machine 1 includes a raw material input port 2, a crosstalk section 3, a vacuum chamber 4,
In the present invention, a vacuum pump (not shown) communicating with the vacuum chamber 5 is stopped. Note that the die 6 has a large number of holes of a fixed shape, so that a large number of raw materials can be extruded at the same time. Further, a cutter 7 is provided at the tip of the extrusion molding machine 1 on the side of the mouthpiece 6, and the cutter 7 is activated at regular intervals to form an extruded product.
なお、カッター７は本装置の必須要件でなく押出製品の

実施例２
第２図は本実施例で使用する成形Ｍ１１０である。It should be noted that the cutter 7 is not an essential requirement of the present apparatus, and it goes without saying that the molded product may be cut to a substantially constant size by the weight of the extruded product. In this case, by putting the blended raw materials into the raw material input port 2 of the extrusion molding machine 1 and operating the extrusion molding machine 1, the carrier can be continuously molded.Example 2 Figure 2 shows the molding M110 used in this example. It is.

Note that the extrusion by the scraper 12 operates intermittently for the holes of the screen 11, and the material is formed into a constant shape.

The physical properties of the prepared carrier are that the water absorption rate is 80.
