Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a wastewater treatment system that uses a supporting frame that supports filter media such as those for anaerobic bacteria on the inner wall of the tank. Regarding the treatment tank, for details, hold the support frame in the specified position and in the specified posture to prevent water leakage. This technology relates to a technology that allows for easy and quick holding without any trouble.

0002

[Conventional technology]

Conventionally, in small-scale combined treatment tanks, anaerobic filter media were placed on the top and bottom of the tank's inner walls. A support frame is installed around the inner wall of the tank to hold it in the middle and to prevent short circuits inside the tank. It is something that can be done. Then, to install the support frame 2, as shown in FIG. overlay and hold the support frame 2 at the overlay part f. Alternatively, as shown in Figure 4, the angular support frame 2 can be secured with bolts or rivets. It is something to keep.

0003

[Problem that the idea aims to solve]

However, as shown in Fig. 3, in the overlay type, it is difficult to attach the support frame 2. It is difficult to determine the position, and the tank inner wall 3 is not vertical and has an L-shaped angle. A support frame 2 with a round shape is not enough; a support frame 2 that corresponds to the slope of the tank inner wall 3 is required; Bolts and rivets have the problem of leakage of waste water through these fixings. there were.

0004 This invention attempts to solve these problems, and its purpose is to The filter can hold the support frame in the specified position and posture without any problems such as water leakage. To provide a sewage treatment tank that can be easily and quickly maintained.

[0005]

[Means to solve the problem]

The sewage treatment tank of the present invention has a sewage treatment tank in which a support frame 2 supporting a filter medium 1 is held on an inner wall 3 of the tank. A mounting surface 4 is provided on the upper surface of the inner wall 3 of the processing tank where the support frame 2 is held. The support frame 2 mounted on the mounting surface 4 is fixed to the rib 5 by a fixture 6. It is characterized by being fixed with screws.

[0006]

[Effect]

In this way, the tank inner wall 3 at the location where the support frame 2 is held is provided with a mounting surface 4 on its upper surface. The supporting frame 2 mounted on the mounting surface 4 is attached to the rib 5 and the fixture 6. By tightening the screws with the ribs 5, the support frame 2 can be positioned with the ribs 5. Place the support frame 2 in a predetermined position on the mounting surface 4 of 5, and screw it to the rib 5 with the fixture 6. This is to avoid the problem of water leakage.

[0007]

【Example】

Sewage treatment tank A is formed as a small combined treatment tank, and its entire structure is as shown in Figure 2. The sewage flowing in from the inlet 7 flows into the first anaerobic filter bed tank 8, and from the inlet 9 into the partition The air is transferred to the second anaerobic filter bed tank 11 through the plate 10, and contact aeration is introduced from the transfer port 12. It is configured to enter the chamber 15 and flow out through the disinfection chamber 14. Such dirt The water treatment tank A may have any configuration.

[0008] In the first and second anaerobic filter beds 8 and 9, there are A support frame 2 is held on the tank inner wall 3. Specifically, as shown in Figure 1, the support frame 2 is attached to the inner wall 3 of the tank at the location where the mounting surface 4 is provided as a substantially horizontal surface on its upper surface. 5 is integrally formed. Thus, the support frame 2 mounted on the mounting surface 4 is moved to the rib 5. A tapping screw 6a serving as a fixture 6 is screwed into the hole 13, and the screw is secured. . In this way, the support frame 2 can be positioned by the ribs 5, and the support frame 2 can be positioned on the mounting surface 4 of the ribs 5. to hold the support frame 2 in a predetermined posture, the support frame 2 can be a plate-shaped one, and the 6 is screwed to the rib 5 to avoid the problem of water leakage.

[0009]

[Effect of the idea]

As mentioned above, this invention has a mounting surface on the inner wall of the tank where the support frame is held, and on the top surface of the tank. The support frame mounted on the mounting surface is screwed onto the rib with a fixing tool. Because it is stopped, the support frame can be positioned using the ribs, and the support frame can be positioned on the mounting surface of the ribs. It is possible to use a plate-shaped support frame without holding it in a specified position, and to attach it to the rib with a fixing device. This has the advantage of avoiding the problem of water leakage.
