There are string-like filter media, but all of them are designed to form a microbial film on the surface of the filter media.

水中のアルカリ度を消費し、汚水のＰＨを低下させる。(To the problem to be solved by the invention) Conventional contact filter media, such as net-like filter media and plate-shaped filter media, effectively form a microbial film on the surface of the filter media, and remove BOD, etc. from sewage by microorganisms. However, in the process of secondary and tertiary high-level treatment, nitrogen compounds contained in wastewater undergo biological nitrification, that is, biological oxidation reaction (NHa + 202 → NO3 + Hz 04-2). As a result, the purification ability decreases. That is, the generated hydrogen ions consume the alkalinity in the wastewater and lower the pH of the wastewater.

リ剤を添加するなどの対策が必要となる問題がある。This decrease in pH suppresses the growth of microorganisms and causes a decrease in the nitrification rate, and also the water quality standards for discharge (PH value 5.8-8.
6) also becomes unsatisfactory. Therefore, there is a problem that requires countermeasures such as adding an alkaline agent.

題がある。Additionally, in order to add an alkaline agent, it is known to fill a contact aeration tank with shells and activated carbon particles to form a contact filter medium (filled filter medium), but this method significantly reduces the porosity of the contact filter medium. Therefore, there are problems such as poor circulation of sewage, low treatment effect, and clogging caused by sludge.

ここで、筒状中空体ａの内部に貝殻５を装填した接触濾
材Ａの作用効果を説明する。(Function and Effect) Here, the function and effect of the contact filter medium A in which the shell 5 is loaded inside the cylindrical hollow body a will be explained.

様の微生物膜処理がなされると共に次の効果がある。The contact filter medium A is a cylindrical hollow body a whose outer shell is made of a lattice-like partition wall, and the shell 5 is charged inside it, so that the cylindrical hollow body a of the outer shell is not easily contaminated with sewage. By contacting and fixing microorganisms thereon, a microbial film treatment similar to that of conventional contact filter media is performed, and the following effects are obtained.

微生物膜が良好に形成されるようになる。That is, the shellfish R5 charged inside the cylindrical hollow body a
... is surrounded by a cylindrical hollow body a, and a space that does not collapse is ensured between the cylindrical hollow body a and the outer periphery of the shell 5..., so that it circulates. It comes into easy contact with sewage, and a microbial film is formed well on the surface of the shellfish R5 together with the outer cylindrical hollow body a.
この微生物膜は、循環して接触する汚水を順次処理する

るようになる。When this microbial film circulates and sequentially treats the wastewater it comes into contact with, the pH value decreases due to biological oxidation, but if the charged shellfish @5 is, for example, Akoya shell, its main component is 93%. % is calcium carbonate (CaCO3), so when sewage undergoes nitrification and hydrogen ions are created,
The calcium carbonate in the Akoya UA shell reacts with these hydrogen ions to become Ca and HCO3, which are then released and neutralize the pH.
ここにアコヤ貝殻を用いた実験例な示す。Here is an example of an experiment using Akoya shells.

In the other container, only the layered hollow body A of the same shape without shells was placed as a contact filter medium, and each container was aerated with the same amount of air.

材ではほとんど変化が見られなかった。The results are shown in FIG. 6, and the pH of contact filter medium A containing shells became neutral in a short period of time, but the pH did not reach the alkaline side after that. On the other hand, almost no change was observed in the contact filter medium 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.

The same wastewater was introduced into Nofu's experimental equipment, and the treatment capacity of contact filter media A containing shells and contact filter media without shells were compared. The results are the values shown in FIG.
この結果から、貝殻入りの接触濾材Ａは、ＰＨの緩衝１
＠力を持っ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, contact filter medium A containing shells has a pH of 1
It can be confirmed that the water has a certain amount of power, and when looking at other water quality, the removal of SS, COD, BOD, and ammonia nitrogen (nitrification) is effective.
次に層状中空体ａの内部に鉄、サンゴ砂、炭酸カルシウ
ム、活性炭、セラミック多孔材等を装入した接触濾材Ａ
には次の作用がある。Next, a contact filter medium A in which iron, coral sand, calcium carbonate, activated carbon, ceramic porous material, etc. are charged inside the layered hollow body a.
has the following effect.
箔状中空体ａ内に鉄板を曲板し凹凸状にしたものを複数
人れた接触濾材Ａにあっては、鉄板と汚水が充分に接触

解しイオン化されて、鉄板表面から溶出した鉄イオンと
結合し、不溶性のりンＭ鉄が生成され、これが微生物膜
中に取り込まれてリン除去がおこなわれる。In the contact filter medium A, in which a plurality of curved iron plates with irregularities are placed inside the foil-like hollow body a, the iron plates and 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 phosphorus (M-iron), which is taken up 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箔状中空体ａ
内に装入した接触濾材Ａにあっては、サンゴ砂の主成分
が炭酸カルシウム（ＣａＣＯ２）であることから、貝殻
５を入れた接触濾材Ａと同様な作用となる。In addition, coral sand made into a rod-shaped body with unevenness is used as a foil-shaped hollow body a.
Since the main component of the coral sand in the contact filter medium A is calcium carbonate (CaCO2), it has the same effect as the contact filter medium A in which the shells 5 are inserted.
また、炭酸カルシウムを固形化し凹凸状の板又は棒状体
として箔状中空体ａ内に装入した接触濾材Ａにあっては
、前述の貝殻５を装入したものと同様な作用となる。Further, in the case of the contact filter medium A in which calcium carbonate is solidified and inserted into the foil-like hollow body a in the form of an uneven plate or rod-like body, the effect is similar to that in which the above-mentioned shell 5 is charged.
また、活性炭を箔状中空体ａ内に装入した接触濾材Ａに

形成が容易で微生物処理の作用が優れたものとなる。In addition, in the case of contact filter medium A, in which activated carbon is inserted into a foil-like hollow body a, in addition to adsorbing various substances in wastewater, the micropores on the surface of the activated carbon become breeding sites for all living organisms, and the formation of a microbial film is prevented. It is easy and the microbial treatment has an excellent effect.

Function to neutralize, increase nitrification, SS, COD, B
Since it also has the function of removing OD, in addition to microbial treatment, it is recommended to select filter media filled with shells, iron, coral sand, calcium carbonate, activated carbon, ceramic porous materials, etc. to be placed inside the cage-like hollow body. It can be used in a way that is adapted to each application, and its effects are not only limited to microbial treatment, but also have multiple functions.Furthermore, sewage treatment is possible with only a contact aeration tank, miniaturization of equipment, and I! ! It is industrially significant because it can be made into R-element, is economical, and has great industrial significance.
