Abstract
PURPOSE: To reduce as much as possible the environmental pollution to be cause by direct discharge of sewage in the case where due to a rainfall the volume of sewage exceeds the simple-processing capacity of a terminal facility into which rain-water and sewage flow together, by bringing and storing a part of it onto a reservoir by use of an automatic control system.
CONSTITUTION: When due to a heavy rainfall the inflow of sewage into a terminal processing facility increases and water level H of pump well 1 rises, calculation control device 20 is activated and intake gate 13 is opened to the full and rain- water 9 is operated operated and thereby the excess sewage is led into rain-water reservior 14 in the case where water level Ho has not reached the upper limit. Only when Ho of the resievoir has reached the upper limitl discharge gate 15 is opened and thereby the sewage is discharged directly. When processing unit 21 has gained room for its processing capacity, the corresponding volume of sewage stored in the reservoir is sent to ejection tank 7 by operating pump 16 and processing is operated
