摘要
This study is concerned with the feasibility of power generation using a pico-hydraulic turbine from sewage flowing in pipes. First, the sewage flow rate at two connection points to the Toyogawa River-Basin Sewerage, Japan, was explored for over a year to elucidate the hydraulic energy potential of the sewage. Second, the performance of the pico-hydraulic turbine was investigated via laboratory experiments that supposed the turbine to be installed in the sewage pipe at the connection points. This study indicates that the connection points have hydraulic potential that can be used for power generation throughout the year. It also demonstrates that the pico-hydraulic turbine can be usefully employed for power generation from sewage flowing in the pipe at the connection points.
本文利用微型水轮机技术,着重对污水管道水力发电的可行性进行了研究。首先,对日本丰川河流域排水系统两连接点处的污水流量进行了一年以上的观测,借此分析污水的水力势能;其次,假定微型水轮机被安装在污水管道的连接点位置,通过实验室试验研究微型水轮机的性能。研究表明:污水管道的连接点处蕴藏有可用于全年发电的水力势能,同时,微型水轮机在该位置可以有效地进行污水水力发电。
