EQUIPMENT FOR KEEPING FIRST RAINFALL IN STORAGE AND AUTO EMITTING IT TO SANITARY SEWER

An automatic discharging apparatus of a sewage pipe line for reserving first rainfall is provided to prevent soil and waste from being flowed to a water tank by installing a sand settling pond and a waste filter net, and to prevent the clean water from being mixed with the rainfall by closing an inlet hole by a water level sensor when the water reaches the target water level of the water tank. An automatic discharging apparatus of a sewage pipe line for reserving first rainfall comprises a diffuser(12), an unmanned control device(20), an inlet water automatic opening and closing device(50), a pretreatment device, and a communication device. The diffuser supplies oxygen to the first rainfall through the air supplied from a compressor motor(14) installed at the upper part of a first rainfall reservoir(10). The unmanned control device transfers the first rainfall to a sewage disposal plant by operating a draining pump(30). The inlet water automatic opening and closing device closes the first rainfall inlet by a water gauge sensor(40) and opens the inlet when the water level is low. The pretreatment device is constituted such as a sand settling pond and a waste filter net to prevent a pump or a pipe from being damaged. The communication device performs the control in the remote controlled area by transferring the command of the command center to a micro controller.
