Description of the Related Art When a wastewater or the like is treated by a biological treatment apparatus, the suspended substance is settled in order to separate the suspended substance from the water containing the suspended substance consisting of sludge particles. A solid-liquid separation device such as a sedimentation basin for solid-liquid separation is used. Here, the sedimentation efficiency of suspended solids in water improves with the increase of the separation area in the sedimentation basin. Solid-liquid separation devices, such as inclined plate type sedimentation basins or inclined tube type sedimentation basins, which increase the water concentration and efficiently settle suspended matter, have been used.

含む堆積物を洗浄することが必要であった。In a solid-liquid separation device such as the above-mentioned inclined plate type sedimentation basin, a suspended substance to be settled normally slides down on an inclined plate provided as a sedimentation promoting material due to gravity to settle. The desired solid-liquid separation is achieved. However, when the above-mentioned apparatus is used for a certain period, microorganisms such as algae adhere to and grow on the inclined plate which is a sedimentation promoting material, so that the smoothness on the inclined plate surface is lost, and suspended substances are removed from the inclined plate. Without being able to slide down, suspended solids accumulate on the inclined plate and the solid-liquid separation ability of the sedimentation basin is reduced. Therefore, it is necessary to wash the sediment containing microorganisms and suspended matter on the sedimentation promoting material at regular intervals.

浄が不十分となる場合があるという問題もあった。In the method for cleaning the sediment containing microorganisms and suspended matter deposited on the sedimentation promoting material by human power, all of the water in the sedimentation basin or the lower part of the sedimentation promoting material is removed. The spouting water from the hose is jetted from above the sedimentation promoting material by human power to wash the sedimentation promoting material.
However, this method requires a great deal of labor when the cross-sectional area of the sedimentation basin is large, and requires that the operation of the sedimentation basin be temporarily suspended and that the water in the sedimentation basin be discarded. There is. There is also a problem that cleaning may be insufficient due to human power.

The automatic cleaning method using a device that automatically disposes the spouting water from the cleaning nozzle onto the sedimentation accelerating material while running the traveling vehicle eliminates the aforementioned problems of the manual method. However, it is necessary to install a special device such as a traveling vehicle equipped with a nozzle, which causes a problem that the equipment becomes large and the cost is increased.

FIG. 1 shows a solid-liquid separation device 1 provided with an upward-flow type inclined plate. Raw water containing suspended substances is introduced into the sedimentation basin 3 from the inflow pipe 2. The sedimentation basin 3 has a deep sedimentation part 4 with a deep tank, which is separated from the discharge side on the inflow side, and the lower part of the sedimentation part 4 is a sludge retention part 5. Further, on the discharge side, there is formed an inclined plate sedimentation section 7 constituted by arranging a large number of inclined plates 6 as settling promoting materials. The raw water flowing into the sedimentation section 4 is subjected to sedimentation treatment in the sedimentation section 4, passes below the partition plate 9, and flows upward in the inclined plate sedimentation section 7, that is, between the inclined plates 6. Pass in upward flow.
Then, when passing through the inclined plate sedimentation section 7, further sedimentation treatment is performed, and the suspended solids settle toward the tank bottom. Since the tank bottom of the inclined plate sedimentation section 7 is inclined so as to become deeper toward the sludge accumulation section 5 side, the suspended suspended solids move to the sludge accumulation section 5 by gravity, and from there at an appropriate timing. Is discharged. Then, the supernatant liquid that has passed through the inclined plate sedimentation section 7 is discharged from the sedimentation basin 3 through the discharge pipe 8.

る。The sedimentation promoting material in the present invention may be formed from any substance as long as it can release silver ions, and may have any structure. Since silver ions have an excellent bactericidal effect on microorganisms such as bacteria and algae, if a substance that releases silver ions is contained in the sedimentation promoting material, the silver ions released will have a bactericidal effect. , The generation and growth of microorganisms on the sedimentation promoting material are suppressed,
This makes it possible to suppress the accumulation of suspended matter. Further, since silver ions have low toxicity, even if the treated water after being treated by the solid-liquid separation device according to the present invention contains a trace amount of silver ions, the treated water can be treated without removing the contained silver ions. Water can be used as raw water for tap water, and treated water can be released into the environment.

And a silver ion releasing substance applied or affixed to the support member.
For example, it is also possible to adopt a configuration in which a substance that releases silver ions, such as a paint or a coating agent containing antibacterial ceramics having silver ion releasing ability, is applied on the surface of the support member. Further, a material that releases silver ions, such as a cloth or a tape containing a nylon thread into which bacteriostatic ceramics having silver ion releasing ability are kneaded, may be attached to the surface of the support member.
