[Structure of the Invention] The present invention has a primary fermenter equipped with a manure inlet and a tertiary fermenter equipped with a clarified liquid outlet in parallel, and a connecting pipe between the primary fermenter and the tertiary fermenter in the lower part of the tank for various types of fermentation. This is a livestock barn manure treatment device in which a secondary fermentation tank is installed, each of which is equipped with a gas discharge port protruding from the nuclide to the outside, and a sludge discharge pipe is provided in the secondary fermentation tank. Since this device is made up of three-dimensional fermenters, the volume of the device is reduced, and it is a simple and efficient livestock manure treatment device. [Example] The apparatus of the present invention will be specifically explained by referring to an example shown in the drawings. FIG. 1 is a perspective view of the device of the invention. FIG. 2 is a longitudinal sectional view of the same type, and FIG. 3 is a square cross-sectional view. - The next fermenter (A) has a manure inlet (11) open at one end,
It is a rectangular covered tank with a connection part (2) for a secondary fermenter at the other end, and a primary fermenter gas exhaust is installed at an appropriate place to discharge the gas generated when excrement is fermented in an anaerobic environment. It is equipped with an exit (3). The secondary fermentation tank (13) has, for example, a rectangular shape, and is equipped with a secondary fermentation tank gas discharge pipe (4) and a sludge discharge pipe (5) approximately in the center thereof, and this gas discharge pipe (4) is a hollow tube whose lower end is in contact with the treated liquid surface and whose other end is exposed outside the tertiary fermenter (C) installed in the second part of the secondary fermenter (B). The sludge discharge pipe (5) is a hollow pipe whose upper end is exposed outside the secondary fermenter (13), and whose lower end is located near the bottom of the secondary fermenter. The secondary fermenter (B) is communicated with the connecting portions (6) and (2) of the processing liquids of the upper tertiary fermenter (C) and the secondary M' tank (Δ). The three-dimensional six-stage tank (C) is a rectangular covered tank installed above the secondary fermenter (B) in parallel with the second fermenter (8). Then, preferably, a plurality of baffle plates are provided alternately inside the nuclide. Then, a waste discharge port (8
) and a cleaning liquid discharge pipe (9) are provided. The above-mentioned types, lids, baffle boards, etc. are constructed of blocks or concrete to an appropriate size depending on the scale of the livestock barn. Generally, the secondary fermentation tank is a rectangular cubic tank with a length of 6 m, a width of 2 m, and a height of 1 m. The secondary fermentation tank is a square cubic tank measuring 6m long, 6m wide, and 3m high.The tertiary fermentation tank is 6m long, 4m wide, and 1m high.
A rectangular cubic tank of about 100 mm is practically suitable. Since the livestock barn manure treatment device of the present invention has the above-described structure, in order to use this device, livestock manure collected from the livestock barn must be fed into the primary fermentation tank (A) through the input port fi+ of the primary fermentation tank (A). Pour into (Δ). It is convenient for later steps to make the distance between the input port and the connection part (2) of the secondary fermentation tank as large as possible to allow sufficient primary fermentation. -The methane gas generated in the secondary fermenter is removed from the primary fermenter gas outlet (3
) is discharged outside the tank. Livestock manure that has undergone primary fermentation in the primary fermentation tank is placed below the connection part (2) of the secondary fermentation tank.
B). The secondary fermenter (B) is a tank in which the main fermentation of excreta is carried out, and has a volume approximately 2 to 3 times the combined volume of the primary and tertiary fermenters, and allows sufficient anaerobic fermentation to take place. A predetermined amount of manure that has undergone primary fermentation in the primary fermentation tank is stored in the secondary fermentation tank, and anaerobic fermentation is allowed to wait for a required period of time. During this time, gases such as methane gas generated by this fermentation fill three sides of the secondary fermenter because this tank is sealed, and as the amount of gases increases, the gas pressure causes the secondary fermentation to take place. Press down on the liquid level in the tank. Additionally, as fermentation progresses, scum rises to the surface of the liquid. The lower end of the secondary fermenter gas discharge pipe (4) provided in the secondary fermenter (B) is in contact with the internal liquid level of this tank, so when the gas pressure comes to -C, this occurs. The liquid on the surface of the liquid in the tank is sucked up together with gas from the lower end of the gas discharge pipe (4) and discharged in two directions. Due to this phenomenon, floating substances such as scum floating on the internal liquid surface are removed from the discharge pipe (
4) and is discharged from the three-way outlet. The secondary fermentation liquid that has undergone secondary fermentation in the secondary fermentation tank is continuously supplied with manure and urine to the primary fermentation tank, filling the primary tank, and fermentation proceeds in the secondary fermentation tank. The gas pressure generated by the fermentation in the tank L) is supplied to the tertiary fermentation 4% (C) through the connecting pipe (6). After this secondary fermentation, the treated liquid undergoes final fermentation in a tertiary fermentation tank and is finished. Then, the gas generated by fermentation in the C1 tertiary fermenter (C) is discharged to the outside from the tertiary fermenter gas discharge 1:] (B). The treated liquid after completion of step (G) is almost clean water, free of solid matter such as scum and bad odor, and is sucked with a pump from the purified liquid discharge pipe (9).
It can be used as washing water for livestock barns, etc. [Effects of the Invention] As described above, the apparatus of the present invention has a three-dimensional installation of the secondary, secondary, and tertiary fermenters, thereby reducing the installation area.Furthermore, since the apparatus is of a covered type, The upper part can be used as a livestock shed. Since sludge, etc. accumulates at the bottom of the secondary fermentation tank, it is easy to remove it, and since it does not use stirring motors, separate cars, floating lids, etc. in conventional purification equipment, the equipment is simple and the facility cost is low. 1-04 Brief explanation of the drawings Figure 1 shows the livestock barn manure disposal device of the present invention.
