ている。(Prior art, problems to be solved by the invention) Conventionally,
Activated sludge methods and anaerobic nitrification methods are generally used as methods for treating wastewater containing organic substances produced by households and factories.More recently, anaerobic nitrification methods have been added to the activated sludge method. A method that additionally combines these methods has also been adopted.

質の濃度が高められた後、汚泥硝化槽内に移送される。In this last method, after removing coarse suspended solids from the wastewater using a settling screen, raw sludge is first separated and removed in a settling tank. Next, the wastewater from which raw sludge has been removed is introduced into an aeration tank and subjected to aerobic treatment using activated sludge, and then introduced into a final settling tank where it is separated into supernatant water and settled sludge. The obtained clear water is discharged into rivers etc. as effluent water, but a portion of the settled sludge is returned to the aeration tank as return sludge and used again for aerobic treatment as activated sludge. On the other hand, surplus sludge other than the returned sludge and the raw sludge are transferred together into a thickening tank. This sludge is further increased in concentration of organic substances in the thickening tank, and then transferred to the sludge nitrification tank.

いという問題もあった。Conventional wastewater treatment methods such as those described above have a problem in that the power cost of the blower used to promote the action of activated sludge is extremely high when performing aerobic treatment using an aeration tank. Ta. Furthermore, since excess sludge in wastewater is separated and treated, there is a problem in that it is costly to transport and treat the large amount of sludge generated. Furthermore, the aeration tank, initial sedimentation tank, final sedimentation tank, etc. used for wastewater treatment require a vast installation area, and the amount of wastewater discharged increases every day. There was also the issue of wanting to make it a target.

嫌気性処理用に使用しても好適な処理効果は得られず、

るというトラブルの発生源となることがあった。Furthermore, conventional water treatment fillers are differentiated between aerobic and/or anaerobic fillers, each used alone, and aerobic fillers for anaerobic treatment. Even if used for treatment, a suitable treatment effect cannot be obtained,
Moreover, in some cases, this may become a source of trouble in that the processing effect of the processing device is reduced.

待できる。If one type of filler can be used for both aerobic and anaerobic treatment, not only will there be no need to use and prepare different water treatment fillers, but there is also the possibility that the treatment tank can be used for both purposes, improving work efficiency. It can be expected to be extremely effective in terms of investment efficiency.
本発明は、上記の問題点を解決するために創出されたも

特徴とするものである。That is, a spherical material with a mesh-like surface is used as a filler to promote the sedimentation of organic substances by activated sludge in the wastewater in the aeration tank and the decomposition of organic substances in the sludge nitrification tank. It is characterized by using a water treatment filler that is a hollow structure and has a plurality of protrusions projecting inward and a hollow cylinder passing through the center of the spherical shape.

It has a plurality of projections (4) extending inward from the sphere. This hollow cylinder (3) preferably penetrates the sphere, but it does not have to, and one end and/or a part of the middle is closed as shown in FIGS. 2A and B. You can leave it there.

解、浄化作用が一層進行する。By using the water treatment filler of the present invention, in the aeration tank, not only is the agitation of wastewater by the air sent from the blower supported, but the filler is also rotated by the rotational action of this air and water flow. In order to make the filler smoother, it is preferable that the filler has a spherical shape without any flange-like protrusions that would allow the filler to interlock with each other. As a result, not only is the wastewater subjected to further agitation by the protrusions inside the filler, but also an unusual agitation action is added by the hollow cylinder provided in the center, resulting in catalytic decomposition of the wastewater by activated sludge, Purification action progresses further.

用は極端に迅速化されることになる。This purification effect is achieved by making the surface of the filler hydrophilic or by providing unevenness on the surface, which improves and promotes the contact between the activated sludge and wastewater, so the water treatment filler of the present invention is used. As a result, the purification effect of activated sludge on wastewater is extremely accelerated.

れる。This water treatment filler is also effective in anaerobic treatment of sludge, and has the effect of promoting sludge decomposition and nitrification in the anaerobic treatment tank. That is, unlike the aeration described above, the decomposition (nitrification) of sludge by anaerobic microorganisms is carried out in an atmosphere where air is blocked, so it is necessary to maintain a state in which microorganisms can easily reproduce and be active.
Use of the water treatment filler of the present invention not only promotes the proliferation and activity of the anaerobic microorganisms, but also facilitates the removal of decomposition products such as methane and nitrogen gas, resulting in anaerobic treatment. This will be promoted. In addition, this promotion effect is achieved by making the top and bottom of the hollow cylinder narrow, or by closing the middle part to make it difficult for air bubbles to enter.This promotes the growth of anaerobic bacteria, and allows the growth of aerobic bacteria in the area excluding the inside of the hollow cylinder. This is further strengthened and promoted by aeration, which promotes the growth of bacteria and incorporates many air bubbles, and by adding irregularities to the surface of the filling material for bacteria retention, and by imparting hydrophilic properties.

の組合わせたものも好ましい結果が得られる。Since the water treatment fillers are used underwater and for long periods of time, they must be made of materials with excellent water resistance, but they also have relatively complex shapes. Therefore, it is preferable to use synthetic resin, which is inexpensive and has excellent processability. However, preferable results can also be obtained using metals such as aluminum alloys, glass, ceramics such as earthenware, wood, bamboo, etc. alone and/or in combination with the above-mentioned plastics.

By being able to use it, the work can be simplified, and by shortening the wastewater treatment time and increasing the amount of wastewater treated, it is possible to reduce investment costs and treatment costs and improve the treatment capacity of the treatment plant.
