Description of the Related Art Recently, a string-shaped contact oxidizing material is put in a purification treatment tank to immobilize and proliferate microorganisms in wastewater, and the food chain of these microorganisms oxidizes nitrogen and phosphorus in the wastewater to produce water. Has been purified. If it is purified in running water such as a river, microorganisms etc. will be easily captured along the flow by the string-shaped contact oxidant, and the purification action will be promoted, but in the case of still water such as sludge or sewage treatment tank Is a water bed type agitator or activated sludge agitator, etc., and water is agitated, and if there is no purification treatment by putting a string-like catalytic oxidant in it, there is little chance that microorganisms will be captured by the catalytic oxidant. , The purification action is not promoted. However, when sewage is agitated by a fluidized bed type purification device or an activated sludge agitation device, the cord-shaped contact oxidant is entangled or stretched, impairing the original performance. Therefore, it is necessary to have a shape in which the contact oxidants are not entangled with each other.

り、互いに絡まることがない。Therefore, various three-dimensional net-like aggregates made of synthetic resin having complicated and irregular voids have been disclosed as shapes which do not get entangled with each other. For example, a large number of thermoplastic synthetic resin filaments in a molten state are spun from a downward nozzle, and the filament synthetic resin is naturally descended and bent to form a mat-shaped, rod-shaped, or pipe-shaped three-dimensional network. A method of forming an aggregate is known (Japanese Patent Publication No. 62-60).
