ている。Septic tanks are used to treat household wastewater and gray water. The septic tank is equipped with a settling tank and an aeration tank according to its processing capacity. Tsuno 1 combined treatment septic tanks for household use are not equipped with a flow rate adjustment tank due to manufacturing costs and other reasons, and wastewater flows directly from the settling tank to the aeration tank. The drainage port between the settling tank and the aeration tank has a large opening to allow efficient drainage.

用される浄化槽には価格の点で課題がある。By the way, the processing capacity of a septic tank is determined in advance. For this reason, if a larger amount of wastewater than the aeration tank can handle at once flows into the aeration tank, such as bath wastewater, etc., the burden becomes too large and the tank cannot be treated, resulting in high BOD wastewater being discharged. As a countermeasure for this, it is necessary to prevent the wastewater that has flowed into the settling tank from being immediately discharged into the aeration tank. One of the countermeasures is to install a flow rate adjustment tank. This can solve the above problem, but if a flow rate adjustment tank is installed, a pump or the like is also required in addition to the flow rate adjustment tank, and septic tanks used in general households have a problem in terms of price.

In the first invention, in a small combined treatment septic tank having a first settling tank, an aeration tank, and a last settling tank, a flow rate is provided between the first settling tank and the aeration tank to adjust the flow rate of wastewater flowing into the aeration tank. A regulating device is provided, and the final settling tank is a small combined treatment septic tank with an aeration pipe and a filter. In the second invention, in a small combined treatment septic tank having an initial settling tank, an aeration tank, and a final settling tank, a flow rate is provided between the first settling tank and the aeration tank to adjust the flow rate of wastewater flowing into the aeration tank. A regulating device is provided, and the first settling tank is a settling portion that separates the solid and liquid! It is equipped with an anaerobic sedimentation tank that has a contact material that fixes the lees and living organisms, and the final sedimentation tank is a small combined treatment septic tank that has an aeration pipe and a filter. The above-mentioned initial settling tank means a tank installed before the aeration tank, and its name and number do not matter. Similarly, the final settling tank refers to a tank installed after the aeration tank, regardless of its name or number. The action flow rate adjustment device discharges wastewater according to the processing capacity of the aeration tank. When more wastewater than the treatment capacity flows in, the flow rate adjustment device first stores it in the sedimentation tank so that it does not flow directly into the aeration tank, and the flow rate adjustment device allows it to gradually flow into the aeration tank. In other words, the upper part of the sedimentation tank has the function of a flow rate adjustment tank. In the case where the sedimentation tank has a contact material that fixes living organisms, pretreatment of wastewater is performed in addition to the sedimentation function and flow rate adjustment function. Since the final settling tank has an aeration pipe and a filter, post-treatment and filtration of the wastewater are performed.
