となる問題がある。(Problems to be Solved by the Invention) Conventional contact filter materials such as net-shaped filter materials and plate-shaped filter materials effectively form a microbial film on the surface of the filter material.
BOD and other substances in sewage are removed by microorganisms, but in the process of secondary and tertiary treatment, nitrogen compounds contained in the sewage undergo biological nitrification, or biological oxidation reactions. NH + 4
+2O 2 →NO - 3 +H 2 O+2H + ), the purification ability is reduced by the hydrogen ions generated. That is, the generated hydrogen ions consume the alkalinity in the wastewater and lower the pH of the wastewater. This decrease in PH suppresses the growth of microorganisms and results in a decrease in the nitrification rate. In addition, water quality standards (PH
values of 5.8 to 8.6) are also not satisfied. Therefore, there is a problem that requires countermeasures such as adding an alkaline agent.

されるようになる。 That is, the shells 5... charged inside the cage-shaped hollow body a are surrounded by the cage-shaped hollow body a, and there is no possibility of collapse between the cage-shaped hollow body a and the outer periphery of the shells 5... Since no voids are ensured, the shell 5 easily comes into contact with circulating wastewater, and a microbial film is favorably formed on the surface of the shell 5 together with the cage-like hollow body a that is the outer shell.

シウムがこの水素イオンと反応してCa+とHCO- 3
となつて溶け出しPHを中性化するようになる。 As mentioned above, when this microbial membrane circulates and sequentially treats the wastewater it comes into contact with, the PH level increases due to the biological oxidation reaction.
Although the value decreases, if the loaded shell 5 is, for example, an Akoya shell, 93% of its main component is calcium carbonate (CaCO 3 ), so if the sewage undergoes nitrification and hydrogen ions are produced, the Akoya shell of calcium carbonate reacts with this hydrogen ion to form Ca + and HCO - 3
It begins to dissolve and neutralize the pH.
ここにアコヤ貝殻を用いた実験例を示す。 Here is an example of an experiment using Akoya shells.
実験：１

量の空気で曝気した。Experiment: 1 Add an acidic agent to clean water and adjust the pH to 3.
Distributed into two containers, one container is charged with contact filter material A containing shells 5 in a cage-like hollow body a, and the other container is filled with only a cage-like hollow body a of the same shape without shells. They were placed as contact filtration materials and aerated with the same amount of air.
結果は、第６図に示すもので、貝殻入りの接触
瀘材Ａでは短時間でPHが中性を示したが、それ以

殻を入れない接触瀘材ではほとんど変化が見られ
なかつた。 The results are shown in Figure 6. Contact filter material A containing shells showed neutral pH in a short period of time, but did not reach any more alkaline value. On the other hand, almost no change was observed in the contact filter material without shells.
この結果から貝殻による効果が確認された。 This result confirmed the effect of shells.
実験：２

である。Experiment: 2 An experiment was conducted over a long period of time using actual wastewater. The same amount of wastewater was flowed into two experimental apparatuses, and the treatment capacities of contact filter material A containing shells and contact filter material A without shells were compared. The results are the values shown in FIG.
この結果から、貝殻入りの接触瀘材Ａは、PHの
緩衝能力を持つていることが確認でき、その他の
水質を見てもSS、COD、BOD、アンモニア性窒
素（硝化）の除去が有効である。 From this result, it is confirmed that contact filter material A containing shells has a pH buffering ability, and when looking at other water quality, it is also effective in removing SS, COD, BOD, and ammonia nitrogen (nitrification). be.

れてリン除去がおこなわれる。 In the case of the contact filtration material A, which has a plurality of curved iron plates with irregularities placed in a cage-like hollow body a, the iron plates and the wastewater come into sufficient contact with each other. At this time, organic phosphorus in the wastewater is decomposed and ionized by microbial treatment, and combines with iron ions eluted from the surface of the iron plate to produce insoluble iron phosphate, which is taken into the microbial membrane and phosphorus is removed. .
また、凹凸のある棒状体としたサンゴ砂を籠状

生物処理の作用が優れたものとなる。 In addition, in the case of the contact filter material A, which has a porous ceramic material inside, if the porous material is used as an uneven plate or rod, the ceramic porous surface becomes a breeding place for microorganisms, making it easy to form a microbial film. The effect of microbial treatment is excellent.

性が大で産業上有意義である。(Effects of the Invention) As described above, the contact filtration material according to the present invention achieves the original performance of the contact filtration material by the cage-like hollow body serving as the outer shell, that is, microbial treatment by adhering and fixing the microbial film.
Filling filter material such as shells placed inside the cage-like hollow body has the ability to neutralize pH, increase nitrification, SS,
Since it also has the function of removing COD and BOD, in addition to microbial treatment, select filling filter materials such as shells, iron, coral sand, calcium carbonate, activated carbon, and ceramic porous material to be placed inside the cage-like hollow body. By doing so, they can be used in a way that is suitable for each purpose, and the effect is not just microbial treatment, but also multiple functions.Furthermore, sewage treatment can be performed using only a contact aeration tank, making it possible to downsize and simplify the equipment. It is highly economical and has industrial significance.
