Abstract
It is expected that the introduction of the advanced sewage treatment will be promoted from now on. As for this research, we have examined if the increase of electric energy consumption that is caused by the advanced treatment can be covered with the recycle and renewable energy produced in the sewage system. About the increase of energy consumption, by introducing advanced sewage treatment, the amount of electric power consumption of the sewage treatment become 1.4 times of that of present system. About the producing of the recycle and renewable energy, we can get the electric power that is equivalent to 55% of the electricity consumption of the present system. The latter is 1.4 times as amount as the former. Consequently, we have shown the increase of the electricity consumption caused by the advanced sewage treatment system can be restrained by the effective utilization of the recycle and renewable energy.
