この発明は、魚介類の増繁殖に適合する海底、湖沼底の
藻場の形成方法並びにその形成材料に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for forming a seaweed bed on the seabed or the bottom of a lake, which is suitable for the reproduction of fish and shellfish, and a material for forming the same.

せんとするものである。It is well known that fish and shellfish are propagated by growing algae on the seabed. One example of this is Japanese Patent Publication No. 62-20162, which is a solvent mixed with manganese sulfate, etc., which neutralizes the alkaline content leached from concrete, and fine powder of iron oxide, which has an effect on the growth of certain types of algae. This is used in Funkrete blocks used for seawalls, etc., to neutralize the alkaline content eluted from the blocks, and the contained manganese salt and iron oxide fine powder promotes the growth of brown algae and red algae. The aim is to propagate fish and shellfish that like to eat algae.

ができるようにした点にある。This invention solves the above-mentioned conventional problems, and its first feature is that it can melt sewage sludge without leaching harmful components by replacing the base material for algae growth with concrete, etc. Another feature is that the molten slag is molded into an appropriate size when cooled, making it possible to produce a base material for algae growth all at once. In other words, in the process of cooling the molten slag of sludge and industrial waste, it is poured into small particles (approximately 50 mm in diameter) or molded into blocks, and the seaweed beds are formed before they are completely cooled. The point is that a propagating agent can be applied to promote drying.

い不定形のものが好適である。This invention will be described in detail below, and its gist will be as follows:
A component for algae growth is applied to the molten slag generated when sewage sludge, water sludge, industrial waste, etc. It was my turn to form. The size of molten slag is determined by its specific gravity of 2 to 2.5, considering the influence of waves and currents, since it settles and becomes fixed on the seabed, lake bottom, etc.
It is desirable that the grain size is 50λ or more, but it may be formed into a size similar to concrete blocks several meters in diameter, which are conventionally used for seawalls. In addition, considering the layered nature of algae, it is preferable that the material be porous like granulated slag and have an amorphous shape with as large a surface area as possible.

る利点がある。In any case, it is important that the algae be stable under water pressure as a matrix for growing algae, and in this respect, it may be placed in a bag or the like and held on the bottom of the water. (See Figure 2) Next, as a means of applying an algae propagation agent to the matrix made of this molten slag, a paint containing a propagation agent may be applied (see Figure 1). A paint containing a propagator may be applied before the molten slag has completely cooled down in step 5 of producing the molten slag. The former method is applied to a large base, and the latter method is used when the molten slag is formed into small particles (about a few diameters). In other words, in the case of molten slag made up of small particles, immersing it in a propagation agent can save a lot of labor compared to applying a propagation agent, and it can also be heated at 50℃ before the molten slag cools down. There is an advantage that drying time can be shortened without adversely affecting the solvent in the paint.

ないものである。If the matrix for propagating the seaweed bed created as described above is placed on the seabed or the bottom of a lake, algae will adhere to it.
Algae flourish due to the growth agent contained in the mother body. and,
Fish and shellfish gather around this algae, forming a fish reef. At this time,
Since the heavy metals contained in sewage sludge and the like are molten slag, they cannot be leached out without causing other harmful effects.

It can be produced quickly, easily, and inexpensively without requiring any special skills by simply using a process, and it has great industrial benefits, such as making it possible to effectively use sewage sludge, which has traditionally been difficult to dispose of. be.
