Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an aeration aggregation chamber for treating human waste.

<Prior art> In general households where there is no public sewer, as a method of human waste treatment, in addition to pumping treatment, septic tank treatment, and composting treatment, foam treatment is performed by treating human waste into foam by microbial decomposition. It was However, the conventional foam treatment is
Since it was carried out by a pipe-shaped device, the oxidized area was not sufficient and it was not possible to always obtain a proper purification state. Also, there was no device for ventilating the inside of the tank, which caused a bad odor, and there were many troubles. As described above, since the conventional foam processing apparatus lacks safety, the development of new technology has been desired.

For this reason, the inventors of the present invention have previously proposed an apparatus that can improve these defects and always obtain a normal purification state (Japanese Utility Model Laid-Open No. 61-204698).

The outline of this device is shown in FIG. As shown in the figure, the human waste treatment device 01 is attached to a manhole cover 03 provided in an opening 02a of a toilet bowl 02. That is, a discharge pipe 04 penetrating the cover 03 is attached to the cover 03, and a lid 0 for inspecting the inside of the discharge pipe 04 is provided at an upper end opening 04a thereof.
5 is provided, and a discharge communication cylinder 07 is connected to the upper side wall surface of the discharge pipe 04. This discharge communication cylinder 07
Has its lower end embedded in the soil and its upper end communicated with the side wall of the middle portion of the discharge pipe 06 whose atmosphere is open,
A suction / exhaust fan 08 is attached to the top end of the discharge cylinder 06. An exhaust pipe 09 is provided which penetrates the manhole cover 03 and communicates with the side wall of the exhaust pipe 04 in order to exhaust the air in the upper part of the toilet tank 02 to the outside.

On the other hand, a conical aeration / aggregation chamber 010 having a downward opening is provided at the lower end of the discharge pipe 04 so as to be immersed in the human urine. Inside the discharge pipe 04, there is provided an air supply pipe 011 having one end connected to an external blower 012 and the other end having an H shape and provided with a large number of air diffusion holes 011a. The H-shaped tip is immersed in the night soil in the aeration / aggregation chamber 010. As a result, air is sent from the blower 012 to the night soil in the aeration / aggregation chamber 010. Incidentally, the toilet bowl 013 is the same as the conventional one.

In order to use such a conventional night soil treatment device 01, an appropriate amount of the microbial preparation is put into the toilet bowl 013 and the manhole hole, and air is supplied from the blower 012 to the aeration chamber 010 to be discharged from the air diffusion hole 011a. As a result, the human waste is oxidatively decomposed, and as a result, the human waste that has been oxidized is convected in the vicinity of the air diffuser 011a. Then, by further supplying sufficient air by the blower 012 to cause convection, microbial decomposition of human waste is activated in the aeration and aggregation chamber 010 to be foamed and foamed, and the foamed bubbles form the exhaust pipe 04. Ascending inside and passing through the discharge communication cylinder 07, the discharge cylinder 06
The gas portion is discharged into the atmosphere by the exhaust fan, and the liquid portion is discharged into the soil from the lower portion 06a of the discharge cylinder 06.

<Problems to be Solved by the Invention> However, in the conventional aeration concentrating chamber 010, the air sent by the air supply pipe 011 activates the microbial decomposition of human urine, and the convection of the microbial decomposition is performed. However, there was a problem that the decomposition efficiency was low.
