近年、湖沼、海域、河川などの停滞性水域における富栄
養化が重大な社会問題となっている。In recent years, eutrophication in stagnant water bodies such as lakes, oceans, and rivers has become a serious social problem.
富栄養化の主原因物質は、栄養塩や有機物と見られてい
るが、このうちリンは富栄養化を促進する主九る因子の
一つとされている。The main causative substances of eutrophication are considered to be nutrient salts and organic matter, and among these, phosphorus is considered to be one of the nine main factors that promote eutrophication.
富栄養化防止対策としては、水域に流入する栄養塩や有
機物の除去がｌ要であるが、それとともに水域内に低濃
度で存在するリンを除去することが有効である。As a measure to prevent eutrophication, it is necessary to remove nutrients and organic matter that flow into water bodies, but it is also effective to remove phosphorus that exists in low concentrations in water bodies.
リン除去方法としては、凝集沈殿法、生物膜リン法、晶

ン法は、基本的に薬品注入を必要としないが、高リン含
有率の汚泥を生成し、これの処理・処分を必要とする。Methods for removing phosphorus include a coagulation-precipitation method, a biofilm phosphorus method, a crystallization dephosphorization method, and an adsorption method, but each method has its own problems. The coagulation-sedimentation method requires the addition of a large amount of coagulant and discharges a large amount of sludge that is difficult to treat. The biofilm phosphorus method basically does not require chemical injection, but it does produce sludge with a high phosphorus content, which needs to be treated and disposed of.
晶析脱リン法は、凝集沈殿法に比べ、ランニングコスト
が安価でろり、いわゆる難脱水性の汚泥が生成しないが
、種晶として使用するリン鉱石が高価であること、工程
が複雑であることが問題点である。Compared to the coagulation-sedimentation method, the crystallization dephosphorization method has lower running costs and does not generate sludge that is difficult to dewater, but the phosphate rock used as seed crystals is expensive and the process is complicated. is the problem.
また、吸着剤を用いた脱リン法も、各種の方法であるが

、水域が微粉で懸濁し、水質汚濁の要因になるばかりか
回収も容易でない。In addition, there are various dephosphorization methods using adsorbents, but in order to fill the adsorption tower, it is necessary to make the particle size uniform and perform granulation, and the materials used are expensive in the first place, so it is not recommended. Not put into practical use. Of course, it is possible to use the material as a fine powder, but if a filled sea is formed, the SS contained in the inflow water will cause clogging, making it impossible for water to pass through. - If sprayed directly onto water bodies, the water bodies will become suspended in fine powder, which not only causes water pollution but also makes collection difficult.
前記したように、従来技術においてはいずれの方法も何

る。FIG. 1 is a perspective view showing an example of the phosphorus removing agent of the present invention, which is a phosphorus removing agent in which fly ash 2 is held in a polyurethane dice-shaped sponge 1. As the carrier having a network structure, a sponge was used here, but in addition, KW! It is possible to use granules formed by entangling wire materials such as fibers, wires, etc., or commercially available gas-liquid contact fillers that have continuous pores inside, and the liquid pressure of the liquid to be used. It is preferable to have a strength that prevents deformation. The shape of the carrier may be any shape such as a cube, a rectangular parallelepiped, a cylinder, a sphere, or an irregular shape, and its size is not particularly limited.
Cod grade is preferable. As the material of the network structure, polyurethane, polyethylene, polyglobylene, polyvinyl chloride, polyacetal, tetron, SUB, 88, etc. are used.
また、網状構造物を有する担体の細径は、リン除去能力

物を用いることにより、静電気的に材料を付着させるこ
とも好ましい。In addition, the fine diameter of the carrier having a network structure must be larger than the diameter of the fine particulate material having phosphorus removal ability,
The fine diameter of the sponge is preferably about 115S2■, and the particle size of the material that has the ability to remove fine phosphorus is 115 to 1/20 of the fine diameter.
Good condition. Materials with the above phosphorus removal ability include:
Fly ash, slag, phosphate rock, bone charcoal, MgO5Z
By using rO1 etc., its diameter is 20~400μ
m1 is preferably used, ilt, 20 to 200 μm. It is also preferable to electrostatically adhere the material by using granules having a network structure formed from ion-exchange fibers.
網状構造を有する担体として、スポンジを使用すると、

率的な再生が可能となり、かつ水洗時間も短絹できる。When a sponge is used as a carrier with a network structure,
Its properties are fragility (property that returns to its original state even when pressure is applied)
Therefore, it is a preferable carrier. That is,
When filling the treatment tower with carriers, other materials often result in rough packing, but in the case of sponge, when pressure is applied from filling soil with phosphorus remover, it becomes a childcare container.
When regenerating the phosphorus remover, the high phosphorus-containing liquid that remains inside the chemical-immersed phosphorus remover can be discharged, making it possible to regenerate efficiently and shortening the washing time.
スポンジは前述のようにつぶしても、もとにもどるので
、きわめて好適である。Sponges are extremely suitable because they return to their original shape even if crushed as described above.

要がある。FIG. 2 is a cross-sectional view of an apparatus filled with the phosphorus removing agent of the present invention, showing the process of removing phosphorus. The inflow water 3 containing phosphorus flows into the treatment tower 4 and comes into contact with the removal agent 5, whereby
Phosphorus is removed and discharged as effluent 6. If a large amount of SS exists in the inflow water and the filtration resistance increases, it is backwashed with backwash water 7 and discharged to the outside of the system. To prevent the sponge from flowing out during backwashing, it is necessary to provide all the perforated plates 8 at the top of the tower.

In addition, fly ash and slag containing CaO also contribute to reactions caused by the precipitation of magnesium phosphate and calcium phosphate.

。3 and 4 are cross-sectional views of an apparatus showing an example of a method for producing a phosphorus removing agent. Figure @3 shows one embodiment of producing the removal agent in the liquid phase. A powder feeder 10 is filled with a fine particulate material 2 having phosphorus removal ability, and the material is supplied to a storage tank 12 of a liquid 11, and is stirred by a stirrer 24 to form a slurry.

浄水２２を吹き込みながら、排出管１８より引き抜く。The slurry is passed through an inflow bonder 13 into a manufacturing tank 16 filled with sponge 1. The support plate (porous) 15 supports the sponge and disperses the slurry. As the slurry passes through the sponge layer, the particulate material 2 is retained inside the sponge. The sponge 1 is held down by a support plate 17 to prevent the sponge from flowing out. Effluent 19 is returned to slurry storage tank 12. The manufactured phosphorus removing agent is drawn out from the discharge pipe 18 while blowing in the washing water 22.
水洗は、スポンジ表面の結合の弱い微粒状材料を洗い流
すために、行なった方が望ましい。It is preferable to wash the sponge with water in order to wash away the weakly bonded particulate material on the surface of the sponge.

It passes through the support plate 17 and is returned to the blowing side of the air supply machine 21.
