(Prior Art) Generally, in a sewage relay pump station, sewage is made to flow into a pit from a sewage inflow channel, and the sewage stored in this pit is sent to a sewage treatment plant etc. by a pump. Since the sewage flowing into the pit contains various types of debris such as large solids, it has been conventional practice to treat such debris before it is sucked into the pump.

The wastewater may be separated from the sewage water using a dust remover or the like before it is sucked into the pump, and then incinerated in an incinerator or dumped in a landfill (hereinafter referred to as the "former treatment method"). Before it flows into the pit, it is crushed finely by an underwater crusher, and then flowed into the pit together with sewage water and pumped (hereinafter referred to as "
The latter method is currently being used.

(Function) According to this garbage processing device, sewage from which garbage has been separated and removed by the dust remover flows into the pit, and is further forced into the water pipe by the pump. When the amount of separated and removed garbage reaches a predetermined amount, the first on-off valve is opened and the second and third on-off valves are opened.
When the on-off valve is closed, the sewage from which dust has been separated and removed is sent through the bypass pipe. In this state, the garbage input port and the drain port are opened, the sewage from the blocked water pipe section is drained from the drain port by the second and third on-off valves, and then the drain port is closed again. Then, the dust separated and removed from the sewage by the dust remover is finely crushed by the dust crushing and feeding machine, and then fed into the water pipe section from the dust inlet. When the amount of garbage supplied reaches a predetermined amount, the garbage inlet is closed, the first on-off valve is closed, and the second and third on-off valves are opened. The sewage that is pumped into the water pipe section will be pumped through the water pipe together with the sewage. Therefore, the dust contained in the sewage is finely crushed without flowing into the pit or passing through the pump, and is then pumped through the water pipe together with the sewage.
