[0003]

[Problems to be solved by the device]

 According to the conventional combined treatment urine septic tank described above, since the outlets of the treated water to be supplied to these aeration chambers are located at the inner bottom of each aeration chamber, these aeration chambers are moved. When the water to be treated rises, the contact efficiency with the contact material and the air is increased, and the aeration efficiency is improved.For example, the generation of debris is extremely small, the anaerobic decomposition is performed efficiently, and the cleanability is improved. It was possible to provide a urine septic tank that is excellent in handling 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 the treated water flowed in, all the openings were immersed in the treated water, so the treated water 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 by a merger process that does not overflow even in such a case.

[0004]

[Means for solving the problem]

 In order to achieve the above object, the flow rate adjusting device of the present invention comprises a first settling separation tank, a second settling separation tank, a pre-filtration tank filled with a contact material, and a contactor in the direction from the inflow port of the water to be treated to the drain port thereof. In a combined urine purification tank in which a first contact aeration tank filled with a material, a second contact aeration tank, a precipitation tank, and a disinfection tank are sequentially formed, a horizontal pipe for setting the surface of the water to be treated in the preliminary filtration tank, A first inflow pipe extending vertically downward from the horizontal pipe and having an inflow port on the end face, and a second inflow pipe extending vertically upward from the horizontal pipe and having an inflow port larger than the inflow port of the first inflow pipe on the end face. An air pipe connected to one end of the horizontal pipe and having an opening at a position higher than the inlet of the second inflow pipe, and an outflow pipe connected to the other end of the horizontal pipe and having an opening in the first contact aeration tank After the merger process, the flow control device for the urine septic tank was constructed.

[0005]

[Action]

 The water to be treated in the pre-filtration tank usually enters the first contact aeration tank from the first inflow pipe through the outflow pipe, but when the water level in the pre-filtration tank suddenly rises, it also flows in from the second inflow pipe. As a result, a large amount of water to be treated is made to flow into the preliminary filtration tank. At that time, air is sent from behind the treated water and from the air pipe along the flow so that the treated water smoothly flows through the outflow pipe.

[0006]

【Example】

 An embodiment of a combined urine septic tank flow rate adjusting device 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 to concrete-made ones constructed on-site to small ones that can be transported. For example, industrial wastewater, livestock wastewater, and domestic wastewater that have flowed into the first settling separation tank 3 from the treated water inflow port 2 of the human waste septic tank 1 are subjected to solid matter settling separation and sewage retention. It is anaerobically decomposed and separated into sludge, scum and intermediate water. Next, the second precipitation separation tank 4 is passed through the baffle 5 and the same treatment as the first precipitation separation tank 3 is performed here. A contact material fixing net 7 filled with a plastic contact material 6 having a length of about 5 cm is provided to prevent the contact material from scattering and adhere to the inside contact material. The decomposing effect of the water to be treated is enhanced by the existing microorganisms, and the water to be treated that has passed through the contact material fixing net 7 flows through the baffle 8 to the supernatant water into the pre-filtration tank 9. 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 first inflow pipe 12 in which a cap 22 having a small-diameter inflow port 21 having a diameter of several millimeters is fitted on the lower side, and an inflow port 23 having a slightly larger diameter than that. The elbow 26 is provided with a second inflow pipe 13 having a cap 24 attached thereto, and an air pipe 14 having an opening 25 in a position parallel to the second inflow pipe 13 and slightly higher than the inflow port of the second inflow pipe 13. The outflow pipe 16 having the opening 27 in the first contact aeration tank 10 is connected to the other side of the cross joint 15 via the cross joint 15, respectively. The part where 16 is connected has a horizontal structure to form a horizontal pipe.

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 suddenly rises. When this occurs, a large amount of water to be treated flows through the second inflow pipe 13 and flows into the preliminary filtration tank 9. At that time, air is sent from the back of the treated water so that the treated water smoothly flows in the outflow pipe 16, or air is fed from the air pipe 14 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, and a pipe for backwashing is installed on the upper surface of the pipe shelf, and further, the pipe shelf described above. The contact material is filled on top of the. An exposed cylinder is provided in a standing state at the center of the first contact aeration tank 10, 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 configured as described above is aerated while the aeration effect by the microorganisms adhering to the contact material is increased, and then sent to the second contact aeration tank 17, 1 After performing the same aeration treatment as 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 for water sprinkling, car washing, industrial water and other miscellaneous water.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, the water to be treated in the pre-filtration tank usually enters the first contact aeration tank through the first inflow pipe and the outflow pipe, but it is temporarily When a large amount of water to be treated flows into the preliminary filtration tank and the water level in the preliminary filtration tank suddenly rises, a large amount of treated water also flows into the preliminary filtration tank from the second inflow pipe. At that time, when the treated water is filled in the outflow pipe and the flow of the treated water stops, the air is sent from the air pipe to the back of the treated water so that the treated water is pushed out. You can It also has the effect of sending air from the air pipe along the flow so that the water to be treated flows smoothly into the outflow pipe when it is not full.
