Description

The present invention relates to a resource utilization system that treats unused trees that have been thinned or harvested, sludge and impurities collected at lakes, sewage treatment plants, etc., and can be used as plant growth materials. .

In recent years, due to the aging of landowners, the rise of imported wood, bamboo and plastic, etc., the use of domestically produced firewood, cedar and bamboo has declined, and domestic forests and bamboo forests have become devastated. In lakes, seas, etc., sludge is abnormally generated due to the eutrophication of water due to the inflow of sewage and wastewater containing chemical synthetic detergent.

By the way, there is Patent Document 1 for treating organic sludge, animal and plant residues, concentrated waste liquid, etc. using wood chips, raw wood, etc., and Patent Document 2 for purifying water quality of rivers and lakes. .

What is described in Patent Document 1 mixes wood chips, raw trees, leaves, weeds, etc. into organic matter sludge, animal and plant residues, livestock manure, and factory concentrated waste liquid, and adds them with an evaporating dryer. Dry by heating, pelletize the dried product, gasify and carbonize in a distillation furnace, use the resulting gas as a heat source in the evaporator and the distillation furnace, the carbide is fuel, soil modifier, It was used as a water treatment agent and deodorization treatment agent.

Moreover, what is described in Patent Document 2 is that the water purification device is floated on a river or lake, and a meandering channel from the inlet to the outlet is formed in the tank body. Is repeated to purify the polluted water, a part of the tank body has a double bottom structure to provide a sludge storage section, and the sludge accumulated in the sludge storage section is discharged to the outside by a pump or the like.

In Patent Document 1, wood chips, raw wood, and the like made into chips are directly mixed with organic sludge, animal and vegetable residues, livestock manure, factory concentrated waste liquid, etc., and dried. The component liquid deviated and could not be used effectively. Further, Patent Document 2 requires that the sludge accumulated in the sludge storage unit be separately treated, which requires a large amount of cost and causes secondary pollution depending on the treatment means. It was.
