JPS6236190A - Tape-shaped microorganism carrier - Google Patents

Abstract

PURPOSE:To improve circulation of a treatment solution in all parts of loop yarn, a microorganism substrate, by making a tape flocked with a great number of loop yarn on one side into a spiral state at intervals while laying the flocked part of the loop yarn outside. CONSTITUTION:The tape 1 flocked with a great number of the loop yarn 2 on one side is made into a coil and retained while the flocked face of the loop yarn is laid outside and intervals are made between spirals. The diameter of a carrier and the distance between the spirals can be properly set as occasion demands without being limited by thickness and shape of the core and the setting density of the loop yarn in a treatment bath can be freely regulated.

Description

Detailed Description of the Invention The present invention provides a structure for a support (hereinafter referred to as a microorganism carrier) for colonizing and propagating microorganisms, which is used when catalytically utilizing the activity of microorganisms to cause various biochemical reactions. Regarding.

In known microbial carriers, carriers in which loops of synthetic resin threads are planted around a rod-shaped metal core facing outward are often used. However, in carriers with such a structure, microorganisms colonized in the loops near the metal core die early due to lack of oxygen, making it difficult to maintain their ability as collateral for a long period of time. (Refer to the specification of Japanese Patent Application No. 60-142,655.) In order to improve such defects, the present inventors have proposed deforming the entire structure into a spiral shape under specific conditions. It is not possible to completely eliminate the drawbacks caused by this problem.-0 The present invention is a tape in which a large number of loop threads are planted on one side, and a distance is provided between each spiral with the loop thread planting surface facing outward. It is designed to form and maintain a coil, and facilitates the flow of liquid to each part of the loop yarn, which is the essential content of the support for the colonization and proliferation of microorganisms. The purpose is to maintain the colonization of microbial communities that occur on the front and back surfaces of the tape by bringing the liquid into contact with the tape, and the diameter of the carrier and the adjacent By appropriately setting the distance between helices, it is possible to arbitrarily adjust the density of loop yarns in the processing tank.

The illustrated embodiment will be described below.

Figure 1 shows the simplest manufacturing method of the carrier of the present invention, in which a large number of multi-filament pieces of viteridene chloride thread are attached to the outer periphery of a metal cylinder (te) in which a heating element (not shown) is installed. The back side of the viteridene chloride tape (1) on which the loop yarn (2) is planted is wound into a coil shape at intervals while maintaining tension. In this way, each of the planted loop threads (2) (cylindrical thread) is unfolded radially around the axis. While maintaining this state, heat the cylinder to the required temperature...
- In the case of vinylidene chloride, when heated to about 70° C. or higher, the tape (1) softens or partially melts. After heating the tape (1) sufficiently so as not to lose its original shape, heating is stopped and the tape is cooled.

Rapid cooling may be applied if necessary. In this way, a coiled carrier having an inner diameter of a cylinder (T) as shown in FIG. 2 can be obtained. Such heating forming means is simplest and most useful when the tape (1) itself or the tape (1) and the loop yarn (2) are made of thermoplastic material such as synthetic resin fiber.

However, if the tape or loop material is not actually suitable for heat forming, if a small amount of different diameters are required, or if the spacing between helices needs to be adjusted appropriately, then In this way, a metal or other filament such as aluminum neem filament (3), which can be deformed at room temperature or below the softening point or melting point of a tape or loop filament, is fixed to the back side of the tape (1), and the filament and the tape ( 1) can be coiled with or without heating, or a similar filament can be penetrated along the tape surface inside the loop yarn (2) as shown in Fig. 4 to form a coil into the tape (1). It is also possible to form a coil by winding it into a cylindrical shape as shown in FIG. 1, for example, while maintaining close contact with the surface. Of course, in the above case, heat molding can also be used if the material allows.

The advantage of using the tape (1) together with the filament (3), which can be plastically deformed without using high temperatures, is that the carrier of the present invention can be formed into any diameter and pitch-changeable after molding without special equipment. It means that you can get it.

As explained above, in the present invention, the microorganism support improves the flow of the processing liquid over each part of the loop thread to promote the colonization and proliferation of microorganisms, and the processing liquid always flows and contacts the back surface of the tape. Since it is possible to supply the necessary nutrients to the microorganisms that colonize the area, its ability can be greatly enhanced compared to known carriers, and it can be used in the processing tank without being limited by the thickness and shape of the core. This tape-shaped microorganism carrier is extremely efficient in that the arrangement of thread density can be freely selected.
