す。[Conventional treatment method] Conventionally, organic sludge from wastewater treatment has been widely incinerated by incineration and disposed of by landfilling, but its impact on the environment, especially carbon dioxide, sulfur oxides and dioxin Emissions from incineration and other emissions from incineration and combustion have a significant effect on the global environment, and incinerated ash and cinders are landfilled. In addition, the landfill method has a limited landfill site, and construction of a new landfill site may not proceed.

みによっても作ることができます。[Problems to be Solved by the Invention] Organic sludge from wastewater treatment is not an incineration method or landfill, but attempts have been made to recycle organic sludge from the viewpoint of effective use of resources. In other words, among the organic sludges generated when the wastewater from the food and pulp industries are treated with biological treatment methods such as activated sludge, those that are unlikely to contain harmful metals are small, but the organic sludge is converted to agricultural land. Attempts have been made to spray the soil and use it as a soil conditioner or organic fertilizer after drying. There is also a method of making compost by mixing sawdust, rice husk and municipal garbage with organic sludge, but since compost is fermentation of organic matter by aerobic bacteria, organic sludge can also be made by stacking.

ており、リサイクルが進まない一因になっています。[0004] In order to industrially recycle a large amount of organic sludge as compost, equipment that controls moisture, temperature, ventilation, etc., and produces it at high speed has been put to practical use. In order for such a method to be feasible, mixed sawdust and rice hulls can be obtained easily and at low cost, there is a commercial compost distribution mechanism, seasonal fluctuations are small, and demand is stimulated. And other conditions must be met.
However, these conditions are not met for recycling,
Recycling costs are being heavily borne by waste companies, which is one of the reasons that recycling is not progressing.
