In step s2, which is a paint application process, the photocatalyst particles are mixed with a paint containing a pigment to create paints of a plurality of types of colors. The paints of different colors are combined and applied to one surface of the wall decoration main body 39 so as to draw a drawing. When the paint is applied, the process proceeds to step s3. In step s3, which is a firing process, the wall decor 35 is formed by firing the wall decor main body 39 to which the paint is applied at 400 degrees or more. When the wall decoration 35 is formed, the manufacturing process is finished.

  By forming such a photocatalytic film 7C on the wall decoration main body 39, a picture 42 having a photocatalytic function can be formed. In the painting 42, for example, a gradation that changes the brightness of the color step by step as shown in FIG. 9 is drawn.

By adsorbing the adsorption surface portion of the mounting member 40 arranged in this way to the wall surface portion 2a of the water tank 2, the wall surface ornament 35 can be easily attached along the wall surface portion 2a.

  When the ultraviolet light U is irradiated to the wall decoration 35 configured in this way, a photocatalytic reaction occurs by the photocatalyst included in the photocatalyst film 7, and sterilization, decomposition of organic matter, and deodorization are performed. Further, the light that is not irradiated to the photocatalyst but is transmitted and reflected by the ornament main body 39 is reflected by the reflecting material 41 and irradiated to the photocatalyst. As a result, a photocatalytic reaction can be caused by more photocatalytic particles, and the sterilization, decomposition and deodorizing effects can be enhanced.

  FIG. 22 is a perspective view showing artificial algae 50. The artificial algae 50 is a pseudoalgae that is placed on the bottom of the water tank 2 and swings with the flow in the water tank 2. The artificial algae 50 includes a base 51, a plurality of linear bodies 52, and a plurality of photocatalytic members 3C.

  The base 51 is generally a rectangular parallelepiped box, and a plurality of fitting grooves 53 are formed. Hereinafter, the longitudinal direction of the base 51 is referred to as the X direction, the width direction is referred to as the Y direction, and the height direction perpendicular to the X direction and the Y direction is referred to as the Z direction. Each fitting groove 53 is formed over two adjacent wall portions extending in the X direction, and penetrates each wall portion in the thickness direction. Each fitting groove 53 is formed at equal intervals in the X direction. More specifically, the fitting groove 53 extends in the Z direction at the first wall 51a, and extends in the Y direction at the second wall 51b adjacent to the first wall 51a. As for the fitting groove part 53, the edge part 53a formed in the 1st wall part 51a is formed in circular shape.

  Each linear body 52 is, for example, a thread, a rope or a string. These linear bodies 52 are provided with a float 55 at one end, and the other end 52a is formed in a spherical shape. The other end 52a of the linear body 52 is formed to be smaller in diameter than the inner diameter r of the end 53b of the fitting groove 53 and larger in diameter than the width L of the remaining portion 53b excluding the end 53. . Further, the linear body 52 is formed such that the remaining portion excluding the other end portion 52a has a smaller diameter than the width L. By fitting the other end 52a of the linear body 52 formed in this way into the end 53a of the fitting groove 53 and moving it along the fitting groove 53, as shown in FIG.

  The photocatalyst member 3C includes a cylindrical photocatalyst member main body 6C, a photocatalyst film 7, and a mounting portion 8C. The photocatalyst member main body 6C, which is an underwater environment purification ornament main body, is made of, for example, an alumina-based or zirconia-based ceramic, similarly to the photocatalyst member main body 6 of the first embodiment. However, it is not limited to ceramic, and resin may be used. A photocatalyst film 7 is formed on the outer periphery of the photocatalyst member main body 6B. The photocatalyst film 7 has the same configuration as the photocatalyst film 7 of the first embodiment, and a description thereof is omitted. The inner diameter of the photocatalyst member main body 6 </ b> C is formed larger than the outer diameter of the linear body 52.

  The mounting portion 8C is similar in configuration to the mounting portion of the first embodiment, and only differences will be described. The mounting portion 8C is formed over the entire inner peripheral portion of the photocatalyst member main body 6C. The mounting portion 8 </ b> C is formed in a cylindrical shape, and its inner diameter is slightly smaller than the outer diameter of the linear body 52. Specifically, the inner peripheral portion of the mounting portion 8C has an inner diameter such that when the linear body 52 is inserted, the mounting portion 8C biases and holds the elastic force against the linear body 52. Is formed. The photocatalyst member 3 </ b> C formed in this way is inserted and attached to the linear body 52. The float 55 has a low density in which the linear body 52 floats in a state in which one or a plurality of photocatalytic members 3C are attached to the linear body 52, in a state in which two photocatalytic members 3C are attached in the present embodiment. It is made of material.

  The artificial algae 50 configured in this way can be shaken with the flow of water to produce a pseudo algae. As a result, sterilization, decomposition and deodorization can be realized without giving stress to aquatic organisms such as fish. Since artificial algae 50 generate oxygen by the photocatalytic member 3C, oxygen can be discharged like real algae, and algae closer to the real can be created. Further, such artificial algae 50 eliminates the need to dispose real algae, and can eliminate replacement work of real algae.

  Further, the other end 52 a of the linear body 52 is fitted into the remaining portion 53 b of the fitting groove 53. As a result, the linear body 52 can be viewed as a flickering simulated algae without detaching from the fitting groove 53.

In addition, by placing a plurality of artificial algae 50, an artificial cocoon can be formed. In addition, since the artificial algae 50 are provided with the photocatalyst members 3C spaced apart from each other, aquatic organisms can create a dwelling place and the like between the photocatalyst members 3C when the cocoons are formed in this way. This eliminates the need for a real bowl.
According to the artificial algae 50 of the present embodiment, the same effect as the mounted object 36 is obtained.

  Further, in the present embodiment, the third and fourth wall surfaces 51c and 51d adjacent to each other adjacent to the first and second wall surfaces 51a and 51b are provided, but these wall surfaces 51c and 51d may be omitted. That is, the base 51 may penetrate in the X direction. The movement of the base 51 can be suppressed by inserting a weight into the through hole. At this time, the base 51 can be made lighter.

  Moreover, in this Embodiment, although the linear body 52 is arranged in parallel by the X direction, it is not necessarily limited to such a structure. For example, when the linear bodies 52 are arranged in the X direction, they may be alternately arranged before and after the Y direction and arranged in a staggered manner. This can prevent the photocatalyst members 3 </ b> C provided in the linear bodies 52 adjacent to each other from colliding with each other. This suppresses the generation of sound and suppresses stress on aquatic organisms.
