However, when an object to be conveyed (filtration or the like) is transported using water (liquid) as a carrier as described above, the amount of water used as the carrier is considerable. Is required. However, reducing the amount of water used at home contributes to energy saving, and in places where the amount of water used is limited, such as outdoor use and nursing care, it is naturally necessary to reduce the amount of water used by the carrier. is there.

Further, in the conventional fluid transport of dirt and the like, since the dirt is transported as it is, the transport pipe itself must have a predetermined large diameter so that the pipe is not clogged by the dirt. On the other hand, when using a pressure feed and drainage system,
A reduction in the diameter of the transfer tube is an essential condition for realizing a reduction in the size of the pressure transfer device.

Accordingly, the present invention proposes a novel waste distribution and treatment apparatus which realizes a reduction in the amount of carrier water and a reduced diameter of the transport pipe in the transport of waste fluid.

[0007]
