ないのである。2. Description of the Related Art Conventional toilets are so-called flush toilets. The problem with this flush toilet is that the flush water, which is used in large quantities, uses high-energy-cost clean water, and a huge amount of energy is consumed to purify the amount of human waste that has been sewn and increased. Energy is consumed. Worse yet, the water purified by the enormous amount of energy may be discharged without 100% being completely removed, and the purification plant itself may become a pollution source. The flushing of the toilet uses a large amount of clean water, which has a high energy cost, only for the purpose of transporting the waste, and as a result, increases the amount of the waste.

The fermentation pattern discussed here is for aerobic high temperature fermentation. As a result, the water in human waste is evaporated. In order to maintain this fermentation pattern, it is necessary to keep the environment in which the microorganisms are easily activated in the fermentation tank 1. The conditions are as follows. Internal temperature of 20 ° C or higher Water content in the fermentor is 30 to 70% Carbon to nitrogen ratio (C / N ratio) 25: 1 to 90: 1 Appropriate amount of oxygen

が攪拌され空気が供給される。In FIG. 1, a substance having a high organic carbon content (such as sawdust and C / C) which is dried (water content of 10 to 20%, C / N ratio of 400 or more) is introduced from the inlet / outlet 6 of the fermenter 1. About 80% of the tank 1 is filled with N balancer, and the heating means 4
Heat to 0 ° C. The fermenter 1 is sealed with a heat insulating material to prevent heat from being released to the outside. The heating means 4 is of a self-temperature control type and is designed to be cut off at a constant temperature. When the human waste 8 from the toilet 7 is put into the fermenter 1 in this state, the C / N balancer absorbs water and human waste containing a large amount of N, and the C / N ratio becomes 90 or less, and the total water Rises to 30-60%. Then, the stirring means 2 which is built-in and driven by the driving unit 3 takes 1-2 times in 6-8 hours.
Slowly rotate for 2 minutes (2 to 3 times / minute), that is, human waste 8
Is stirred and air is supplied.

When the internal temperature rises to 50 ° C. or higher, the evaporation of water becomes vigorous, and the evaporated water is discharged from the exhaust fan 5 to the outside of the system. If the water content of the fermenter 1 is balanced when the water content of the discharged water and the water content of the input urine are balanced. That is, as shown in the following table, the water in the urine is evaporated and dried. Internal temperature is 60 ℃
Because of the above, harmful bacteria such as Escherichia coli and eggs of parasites die, resulting in hygienic compost as shown in FIGS. 2 and 3. The compost is taken out from the input / output port 6. * Measured with a sample taken from about 10 cm from the top of the compost ** Measured with a sample taken from the bottom of the compost

The ratio becomes smaller (Table 2). It is necessary to take out a part of the compost and replenish the C / N balancer at an appropriate time (a few months in an actual example). In the embodiment, 30 l of compost is taken out and 15 l of C / N balancer is put therein. This carbon is burned in the microorganism body and consumed as energy for fermentation. As shown in Table 3, the extracted compost is excellent as an organic fertilizer, and is odorless and hygienic, so that it can be effectively used. (Note) The value after 63 days is the value after taking 14.2 kg of compost from the composting toilet and adding 7.3 kg of sawdust.
