[0003]

According to the conventional combined treatment urine septic tank described above, since the outlets of the water to be treated to be supplied into these aeration chambers are located at the inner bottom of each aeration chamber, When the water to be treated that moves inside these aeration chambers rises, the efficiency of contact with the contact material and air is increased, and the aeration efficiency is improved. For example, the generation of cass is extremely low, and the anaerobic decomposition is efficient. It is possible to provide a urine septic tank which is excellent in cleanability and has a convenient handling that does not scatter the contact material during washing from the pre-filtration chamber and the first aeration chamber. When a large amount of water to be treated flows into the water, all the openings are immersed in the water to be treated, so that the water to be treated could not be sent from the pre-filtration chamber to the first contact aeration chamber and overflowed. Therefore, the present invention has been made for the purpose of providing a flow rate adjusting device for a urine septic tank which is subjected to a merged process and does not overflow even in such a case.

[0004]

In order to achieve the above-mentioned object, the flow rate adjusting device of the present invention comprises a first settling separation tank, a second settling separation tank, and a contacting section from the inlet of treated water toward the outlet thereof. In the combined treatment urine purification tank in which a pre-filtration tank filled with a material, a first contact aeration tank filled with a contact material, a second contact aeration tank, a precipitation tank, and a disinfection tank are sequentially formed, treated water of the pre-filtration tank A horizontal pipe that sets the water surface of the first pipe, a first inflow pipe that extends vertically downward from the horizontal pipe and has an inlet on the end face, and a vertical pipe that extends vertically upward from the horizontal pipe to the end face from the inlet of the first inflow pipe A second inflow pipe having a large inflow port, an air pipe connected to one end of the horizontal pipe and having an opening at a position higher than the inflow port of the second inflow pipe, and a first contact connected to the other end of the horizontal pipe Adjusting the flow rate of a combined treatment and urine septic tank consisting of an outflow pipe with an opening in the aeration tank You configure the location.

[0005]

The water to be treated in the pre-filtration tank normally enters from the first inflow pipe through the outflow pipe into the first contact aeration tank. However, when the water level in the pre-filtration tank rises suddenly, it flows from the second inflow pipe. In addition, a large amount of water to be treated flows into the preliminary filtration tank. At that time, air is fed from behind the treated water and from the air pipe along the flow so that the treated water smoothly flows in the outflow pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the flow rate adjusting device for a combined urine septic tank of the present invention will be described with reference to the drawings. The human waste septic tank 1 shown in FIG. 1 and FIG. 2 can be applied from concrete construction constructed on site to small transportable constructions. Inflow port 2 of the treated water of this human waste septic tank 1
From the first settling separation tank 3, for example, industrial wastewater,
Livestock wastewater and domestic wastewater are subjected to sedimentation and separation of solids here, as well as to anaerobic decomposition due to retention of sewage,
Separate into sludge, scum and intermediate water. Then baffle 5
The second precipitation / separation tank 4 is passed through and the same treatment as that of the first precipitation / separation tank 3 is carried out. In this second precipitation / separation tank 4, for example, the diameter is about 3 cm and the length is 5 cm. A contact material fixing net 7 filled with about a centimeter of plastic contact material 6 is provided, the contact material fixing net 7 prevents the contact material from scattering, and the contact material fixing net 7 is covered by the microorganisms attached to the contact material. The water to be treated that has passed through the contact material fixing net 7 enhances the effect of decomposing the treated water, and the supernatant water thereof flows into the preliminary filtration tank 9 through the baffle 8. The preliminary filtration tank 9 has an appropriate filter, and the water to be treated filtered by the filter flows into the first contact aeration tank 10 filled with the contact material through the flow rate adjusting device 11. ing.

As shown in FIG. 3, the flow rate adjusting device 11 has a cap 2 having an inflow port 21 having a small diameter of several millimeters at the bottom.
The second inflow pipe 1 in which the first inflow pipe 12 in which 2 is fitted and the inflow port 23 having a diameter slightly larger than that of the first inflow pipe 12 in which the cap 24 is fitted
3 and an air pipe 14 having an opening 25 in parallel with the second inflow pipe 13 and at a position slightly higher than the inflow port of the second inflow pipe 13 are connected to three sides of the cross joint 15 via elbows 26, respectively. The outflow pipe 16 having the opening 27 is connected to the first contact aeration tank 10 to the other side of the cross joint 15, and the portion of the cross joint 15 to which the outflow pipe 16 is connected is horizontal to form a horizontal pipe. It has been configured.

As a result, the water to be treated in the preliminary filtration tank 9 normally enters the first contact aeration tank 10 through the first inflow pipe 12 and the outflow pipe 16, but the water level in the preliminary filtration tank 9 rises rapidly. At this time, a large amount of water to be treated flows into the preliminary filtration tank 9 by also flowing in from the second inflow pipe 13. At that time, air is sent from the air pipe 14 from behind the treated water so that the treated water smoothly flows in the outflow pipe 16, or along the flow.

In this way, the water level of the first contact aeration tank into which the water to be treated flows is slightly lower than that of the outflow pipe 16. Although not shown, the first contact aeration tank 10 is provided with a pipe shelf for fixing the contact material on the inner bottom thereof, and a backwash pipe is installed on the upper surface of the pipe shelf, and the pipe shelf is further provided. The contact material is filled on top of the. An exposed cylinder is provided in the center of the first contact aeration tank 10 in an upright state, and an air supply pipe for supplying air from above to below is provided.

The water to be treated supplied to the first contact aeration tank 10 constructed as described above is aerated while the aeration effect of the microorganisms adhering to the contact material is increased and sent to the second contact aeration tank 17, 1 After performing the same aeration treatment as that in the contact aeration tank 10, the sedimentation tank 18 and the disinfection tank 19 are sequentially passed through the drainage port 20 to be naturally drained or discharged by a pump action, or toilet flush water, trees It can be used as water spray, car wash, industrial water, and other miscellaneous water.

Since the present invention is constructed as described above, the water to be treated in the pre-filtration tank normally enters from the first inflow pipe to the first contact aeration pipe through the outflow pipe, but from the inflow port temporarily. by the time rose water level of the pre-filtration tank suddenly even flow a large amount of water to be treated, the that has become to flow much of the water to be treated in the preliminary filtration tank also flows from the second inlet pipe . or,
In order for the water to be treated to flow smoothly through the outflow pipe,
It has the effect of feeding air from the air tube along the flow.
