2. Description of the Related Art Today, as environmental destruction of the earth is being called for, it is becoming impossible to deal with wastewater treatment using sand, gravel, and charcoal, which have long been used as filters for wastewater. There is. For this reason, a filter device using a filter material such as a ceramic sphere, a polystyrene foam ball, or a synthetic resin material has been used as a filter material in place of these.

However, there is no place to dispose of these as industrial waste after use, and if incinerated, they often emit harmful smoke and cause pollution. In addition, synthetic resins are disadvantageous in that many of them adversely affect the human body due to harmful components during use.

Further, in the filtration device using the above-mentioned filtration material,
Since the filter material becomes clogged during use, it is necessary to replace the filter material in a short period of time, and it takes time to carry it out and store it in the filtration tank. I need a couple of husbands. Further, if left as it is, there is a problem that the ceramic spheres, the polystyrene foam balls, and the filter material made of a synthetic resin material are broken, and the dust and the like are ejected from the filtration tank. There is also a problem that the density of the filter medium cannot be adjusted unless the filter medium is replaced.

The present invention solves these problems and provides a filtration device which is harmless and easy to treat after use, is less likely to cause clogging, does not require replacement for a short period of time, and is light in weight, so that replacement work is easy. The purpose is to do.
