ことである。However, there are various modes of water pollution load in large and medium-sized river lakes and ponds, and it takes labor and time to analyze this and set the capacity and function of the purification device. It is difficult to determine the standard because there are many deterministic factors. In addition, in actual design, it is necessary to consider each case and decide the capacity and shape, which requires a lot of labor for design. In addition, a great deal of labor and construction time are required for on-site construction. The first problem to be solved by the present invention is to improve the above-mentioned difficulties and to provide a simple purification device. The second problem to be solved by the present invention is to provide a device that makes effective use of natural water energy of rivers and the like and enables water purification without power. And the installation place of the apparatus is to provide an apparatus which can be installed not only on land but also in the water of a river lake pond.

ものである。[Means for Solving the Problems] As a means for solving the first problem, a box culvert, which has been standardized, is used as a water tank of a catalytic oxidation purification apparatus. Is a box culvert made of concrete filled with a contact oxidant, and an air diffuser and a sludge extraction device are installed at the bottom of the box culvert to form a unit treatment tank. And a series of water channels, and the inlet side and the outlet side of the series of channels are closed with concrete box plates to form independent treatment tanks, and one side of this treatment tank has a waste water inlet.
An outlet for treated water is provided on the other side. If this is specifically described based on the drawings, the box culvert 1 can calculate the volume by the cross section and the length. That is, by determining the residence time corresponding to the load condition and the specific capacity of the contact oxidant, it is possible to calculate the required water tank volume according to the inflow amount. To further elaborate on this,
As raw water conditions, inflow raw water amount = Q (m3 / D) Polluted suspended solids amount = SS (mg / L) Biochemical oxygen demand = BOD (mg / L = g / m3) Total BOD amount = BOD × Q = g / M3 × Q (m3 / D) Treated water conditions: BOD removal rate = 50% to 75% An example of calculating the purification device capacity is as follows: BOD area load (AL) = 0.010 kg / m2D (water quality load・ Depending on water tank / contact material conditions) Required contact material total surface area (A) = total BOD amount ÷ BOD area load (A) = kg / m3 x Q / 1,000 (m3 / D) ÷ 0.010 kg
/ M2 ・ D Contact material unit surface area (a) m2 / m3 ・ ・ Depending on material Purifier basic capacity (V) = A ÷ a Purifier margin (α) = 1.3 to 1.7 Therefore, the required purification device capacity (V ′) can be calculated by α · V. Further, the unit capacity (V ′) of the box culvert can be calculated for each standard. That is,
Since the unit capacity (V ′) of the box culvert is the cross-sectional area × length, the capacity is calculated for each standard of the culvert 1 and used as the capacity standard. In this way, the above-mentioned total BOD amount, AL, A, a, and α based on the water quality condition are set, the actually required box culvert capacity V ′ is obtained, and the unit capacity (V ″) that conforms to the local condition is obtained. By selecting it, the main body of the septic device can be decided, that is, the main body of the septic tank does not need to be structurally calculated, only the civil engineering design and construction such as the foundation of the site is required. As shown in the figure, the concrete structure of the above-mentioned purification system is that the bottom of the box culvert 1 is provided with slopes 2 on both sides to make it easier for sludge to collect, and the center of the sludge. The sludge drawing pipe 3 is installed in the container, and the aeration diffuser 4 is installed and the contact oxidizer 5 is filled in. A plurality of units corresponding to the amount of inflow water are connected as one unit, and then the inflow side is connected. By connecting the concrete box plate 6, 9 constituting the water tank to the outflow side.
The concrete box plates 6 and 9 are provided with an inflow port 8, a submersible pump 13, a pipe 14, an outflow port 11 and a pipe 15, respectively, and rectifying walls 7 and 10 are provided on the septic tank side, respectively. Depending on the type of the contact oxidant 5, the flow regulating walls 7 and 10 also serve to prevent the contact oxidant 5 from flowing out. An air diffuser 4 is provided below the outflow-side concrete box plate 9 to make the amount of oxygen in the discharged water appropriate. A sludge drawing pump 16 is provided inside the outflow side concrete box plate 9. Next, as a means for solving the second problem, as shown in FIG. 3 and FIG. 4, the treatment tank having the above-mentioned structure is installed with this purifying device at a position lower than the water level of a flowing river, A weir 12 is installed after the inlet 8 on the upstream side to stop water, and the water level difference h
As a result, the river water is made to flow in through the inflow port 8, passes through the straightening wall 7 and the contact oxidizer 5, and is made to flow out through the outflow port 11. By this method, this facility can be installed in small and medium rivers. Large rivers and lakes and ponds that cannot be stopped by the weir 12 are to be installed underwater. At this facility using the box culvert 1, the on-site construction is reduced and the inflow side concrete is The inflow pump of the box plate 6 is closed, the submersible pump 13 is installed inside, the raw water is sucked through the inflow pipe 14, is pressed into the contact oxidation tank through the straightening wall 7, is purified, and is discharged from the outflow port 11. Is.

Sent in. Then, the microorganisms adhering to the contact oxidant 5 and proliferating are activated by oxygen in the water, contact with organic matter, decompose the organic matter and use a part as a nutrient source, and the other as waste sludge to purify wastewater. Is something that can be done. When the BOD load of the inflowing wastewater is large and the amount of oxygen is insufficient, the air diffuser 4 supplies air to supplement oxygen. When sludge is accumulated, the sludge adhering to the contact oxidant is dropped to the bottom by the air diffuser 4 and collected, and then discharged to the outside by the drawing pump 16 attached to the sludge drawing pipe 3. . The treated water in which the organic matter has been reduced and clarified in this way passes through the straightening wall 10 and is fed with air by the air diffuser 4 to increase the amount of residual oxygen.
After 1, it is returned to the original water. Further, when the device according to the present invention is used in a small or medium-sized river, a weir 12 can be installed, and an operation without power can be performed by utilizing the water level difference between the weir 12 and the water level of the treatment tank. When used in a lake pond, it is operated by the submersible pump 13.

い。As is apparent from the above description, according to the present invention, it becomes easy to adapt to the local conditions in the practical design, and the box culvert capacity standard is selected when the load and the purification target are set. However, it is possible to design if the local topography and geological response and the installation method are decided. From the construction side,
For construction of purification facilities around rivers and lakes and ponds, it is sufficient to perform box culvert assembling work, contact oxidizer installation work, and some civil engineering work such as foundations, which simplifies on-site work and shortens construction period. , Can reduce costs. In addition, it can be installed directly on a small river, and in this case, it is installed at the bottom of the river to operate by inflowing and outflowing sewage due to the difference in running water level, so purification is possible without using power. It is economical. At the same time, since the installation site is underwater, no special site for the purification device is required.
