See Te Bng, p. 34 (1974). However, this method connects a second denitrification tank and a second aerobic tank after the denitrification tank and aerobic tank to achieve a high rate of N removal. In addition to the measurement, it is necessary to install an absolute anaerobic tank in front of the nitrification process. Therefore, in order to install this treatment equipment, a large site is required and a large amount of money is required to construct the equipment. In addition to contributing to costs and long periods of time, it is also necessary to send wastewater to various locations and return treated water, and it requires a large amount of energy to operate the treatment equipment, while reducing the amount of land used. In addition, in order to reduce operating costs, the deep shaft aeration method (deep shaft gross aeration method), in which an aeration tank is installed deep underground, is used.
However, in this case, the cost of installing all the aeration systems deep underground is not necessarily cheap, and there are many disadvantages such as lA.

すことができる。(Means for Solving the Problems) The general-purpose sewage treatment device of the present invention consists of two tanks, an anaerobic tank and an anaerobic/aerobic tank, which are provided to maintain the same water level before sewage flows in. are two upright, mutually parallel rows of thick ceramic tubes'!
It consists of a 0-shaped pipe in which 4g of concrete rings such as heavy pressure pipes are connected with a bent pipe at the lower end, one pipe is an inflow pipe, the other is an outflow pipe, and the inflow pipe has a branch for introducing sewage. The outflow pipes are each provided with branches leading to the aerobic and aerobic tanks, and the anaerobic and aerobic tanks are two lines of upright, mutually parallel conduits connected at their lower ends by a water tank. At the very least, one side is an inflow pipe and the other side is an outflow pipe, and a partition is provided at the upper part of the water tank between the inflow pipe and the outflow pipe, and an aeration device is provided in the tank below the outflow pipe. In history, the first inflow pipe is a branch pipe that introduces wastewater from the μ anaerobic tank, and the final outflow pipe is filled with μ-treated wastewater! A plate pipe is installed in each pipe, and the upper end of the intermediate outflow pipe is designed to return part of the wastewater that has passed through the outflow pipe to the previous inflow pipe, and send the remaining part to the next outflow. This is a general-purpose sewage treatment equipment, which is equipped with a pipe conduit, and has a contact door material inside the inflow pipe and outflow pipe of the anaerobic tank and the anaerobic/aerobic tank, respectively. BA is explained as follows. After digging holes corresponding to anaerobic tank 1 and anaerobic/aerobic tank 2, and reinforcing the surrounding area with concrete,
The anaerobic tank is constructed by connecting two lines of conduits 3 and 4 parallel to each other upright to the bottom of the hole with a bent pipe 5 at their lower ends, one of which is connected to the inflow pipe 3. , the other fr: outflow pipe 4
shall be. The inflow pipe is provided with a branch pipe 6 for introducing sewage, and a branch pipe 7 for introducing μ sewage into the outflow pipe and the next anaerobic/aerobic tank. Similarly to the anaerobic tank, the anaerobic/aerobic tank has two rows of upright, mutually parallel conduits 8 and 9 connected at their lower ends by a water tank 10, with one being the inflow pipe 8 and the other being the flow 1fj'! Let it be r9. A partition wall 11 is provided above the water tank between the inflow pipe and the outflow pipe to control the mud storage of sewage flowing from the inflow pipe to the outflow pipe, and an aeration device is provided in the water tank below the outflow pipe. Gas is introduced into the outflow pipe to create an aerobic condition. In order to make it easier for sewage (particularly sludge) to flow from the inflow pipe to the outflow pipe, it is desirable to provide a steep slope 13 in the water 81 portion below the inflow pipe so that the sewage can more easily move from the inflow pipe to the outflow pipe. A pipe conduit 14i is provided at the upper end of the outflow pipe so that a part of the treated wastewater is returned to the inflow pipe, and the other part is sent to the next inflow pipe, and it is necessary to pass through the branch pipe 16. Flows into the settling tank. The inflow and outflow pipes of these six pipes are filled with a contact material to treat wastewater with a fixed biofilm. The outer periphery of these U-shaped 4w is used as a protection plate 18, and the gap between this protection plate and the hole is filled with a heat insulating material. The entire deodorizer is placed on the upper part, covered with a lid 19, and an exhaust pipe 20 is provided in the middle part of the lid 19 to discharge the gas emitted from the Japanese cypress to the outside. In the drawing, the anaerobic tank is one 0-shaped tube, and the anaerobic/aerobic tank is two 0-shaped tubes, but the number can be increased if necessary.
can be done.

It is a method in which concrete pipes such as pressure pipes are stood upright and connected to form a U-shaped pipe.For example, it is thought that the depth seen in the deep shaft method is divided and the R-shaped pipe is changed to a U-shaped pipe of the possible depth. Unlike the deep shaft method, which uses only aerobic treatment, there is no need to create deep underground (for example, about 200 meters), and construction can be completed in a short period of time, resulting in lower construction costs. Furthermore, in the anaerobic/aerobic tank of the general-purpose sewage purification device of the present invention, one of the KU'# pipes is made of anaerobic cypress and the other is made of an aerobic tank, as described above.
At the bottom of the aerobic tank, an aerobic device such as an OH type aerator is installed, and in addition to the aerobic tank, there are also materials inside the tank that have an extremely large specific surface area and are difficult to get stuck. For example, see Japanese Patent Application No. 60-81274), wastewater is purified using the fixed biological method, and a part of the wastewater that has passed through the outflow pipe is returned to the original inflow pipe, so it is possible to eliminate N - It has a purification ability comparable to advanced treatment techniques such as the modified Bardanho method, which uses aerobic and aerobic agents 1114 times. In addition, various U
Since all of the pipes are positioned, the raw wastewater from the outside area moves by the amount that it flows in, and the wastewater is treated.

By alternating between aerobic conditions and aerobic conditions, the ability to purify wastewater is large due to the formation of a fixed biofilm. It can be installed in the basements of buildings, agricultural canals, the bottoms of rivers and lakes, and in sewers, where installation was not possible.
