Description

本発明は,集排水施設における集排水管閉塞防止工法に関するもので,集排水施設において鉄やカルシウム等の塩類が豊富に含有している地下水が流れることによって,塩類を主体とした目詰まり物質が付着して排水管が閉塞することが問題となっている。 The present invention relates to a method for preventing clogging of collection and drainage pipes in collection and drainage facilities, and clogging substances mainly composed of salts are generated by the flow of groundwater containing abundant salts such as iron and calcium in the collection and drainage facilities. It is a problem that it adheres and clogs the drain pipe.

このような問題に対して,木,草,残滓の未分解の有機物を炭の製造過程で産出される強酸性の有機酸に適量漬け込み,長期間養生することで製造されるフルボ酸およびフミン酸を利用することで閉塞物のイオン化を維持して集排水管への付着を緩和することを可能としたものである。 To solve this problem, fulvic acid and humic acid are produced by immersing an appropriate amount of undecomposed organic matter such as trees, grasses, and residues in strongly acidic organic acid produced in the charcoal manufacturing process and curing for a long period of time. It is possible to maintain the ionization of the blockage and reduce the adhesion to the collection and drainage pipe.

通常行われている集排水施設における塩類を主体とした目詰まり物質である炭酸カルシウム(CaCO3)を抑制する方法としては,(1)全炭酸濃度に占める炭酸イオン濃度の割合を小さくする方法,(2)カルシウムの微小粒子の粒径を揃えて特定の結晶が肥大化するのを防止する方法,(3)析出した炭酸カルシウムの結晶粒子を分散させ,凝集するのを防止する方法,(4)粗大化し易い結晶核の結晶成長面にひずみを与えて正常な結晶の成長を防止する方法がある。 Methods of suppressing calcium carbonate (CaCO 3 ), a clogging substance mainly composed of salts, in collection and drainage facilities that are usually practiced include: (1) reducing the ratio of carbonate ion concentration to the total carbon concentration; (2) A method of aligning the particle size of calcium microparticles to prevent specific crystals from growing, (3) A method of dispersing precipitated calcium carbonate crystal particles to prevent agglomeration, (4) ) There is a method of preventing normal crystal growth by applying strain to the crystal growth surface of crystal nuclei that tend to coarsen.

この手法のうちで,(1)については集排水施設に流入する集排水に酸を添加してpHを6.5~7.0に保つ方法で,従来から広く一般的に採用されていた。しかし,このような方法では,炭酸カルシウムの析出を防ぐことはできるが,腐食を同時に抑制することが困難であることから,今日ではあまり利用されなくなってきている。 Of these methods, (1) is the method of adding acid to the waste water flowing into the waste water collection facility to keep the pH at 6.5 to 7.0, which has been widely used for a long time. However, although this method can prevent the precipitation of calcium carbonate, it is difficult to suppress corrosion at the same time.

(2)については,炭酸カルシウムスケールの生成防止作用をもった薬品としてポリリン酸塩,ホスホン酸類,高分子電解質類などが知られている。ポリリン酸塩は,滞留時間の長い高濃縮系ではオリトリン酸への加水分解率が高くなるので利用することができないなどの問題がある。 As for (2), polyphosphates, phosphonic acids, polymer electrolytes, etc. are known as chemicals that prevent the formation of calcium carbonate scale. Polyphosphate has a problem that it cannot be used in a highly concentrated system with a long residence time because the hydrolysis rate to oliphosphoric acid increases.

(3)と(4)については,スケール除去剤やスケール抑制剤の定期的,常時の投入が必要となり,アルカリ剤による中和処理が必須で,廃棄された酸や中和処理による塩を産業廃棄物として処理する必要がある。また,スケール抑制剤は,結晶の凝集や結晶の粗大化を抑制するもので,効果を得るためには薬剤を常時添加するシステムが必要であり,継続的に効果を出すには多大な費用がかかる。一般的には,スケール抑制剤としてポリリン酸塩やホスホン酸を主体とするものが用いられるが,これらは植物の肥料となるリン酸塩の一種であることから,下流河川において藻類が異常に発生するなどの環境悪化が危惧される。 As for (3) and (4), scale removers and scale inhibitors must be added regularly and constantly, and neutralization with alkaline agents is essential. Must be treated as waste. In addition, scale inhibitors suppress the agglomeration of crystals and the coarsening of crystals, and in order to obtain the effect, a system in which the agent is constantly added is required, and it is very costly to achieve the effect continuously. It takes. Generally, polyphosphates and phosphonic acids are used as scale inhibitors, but since these are a type of phosphate used as fertilizer for plants, algae grow abnormally in downstream rivers. There is concern about environmental deterioration such as

This is a method for removing calcium scale, characterized by removing calcium scale adhering to the inside of the collection and drainage pipe.

集排水の原液は,pH7.48(微アルカリ性),EC(電気伝導度)2.23dS/mとなるのに対して,10倍希釈ではpH3.25(強酸性)となるが,50倍希釈以上では弱酸性~中性となることから鋼材の腐食は起こらないと考えることができる。EC(電気伝導度)については,フルボ酸(フジミン「登録商標」)が集排水の原液に対して10倍~500倍に希釈されるように混合しても最大で2.23dS/m→2.55 dS/m(0.32 dS/m)しか変化しないことが確認できた。 [Effect confirmation test 2]
In Matsue City, Shimane Prefecture, tests were conducted on changes in pH and EC (electrical conductivity).

[Table B] Types of solutions and changes in pH and EC (electrical conductivity)
The undiluted solution of collected wastewater has a pH of 7.48 (slightly alkaline) and an EC (electrical conductivity) of 2.23 dS/m. Since it is weakly acidic to neutral, it can be considered that corrosion of steel materials does not occur. EC (Electrical Conductivity) is 2.23 dS/m → 2.55 dS at maximum even if fulvic acid (Fujimin “Registered Trademark”) is mixed so that it is diluted 10 to 500 times with respect to the undiluted solution of collected wastewater. /m (0.32 dS/m).

This trend indicates that the ionized ferrous iron (Fe 2+ ) increases in the solution when the dilution ratio is lowered.

[効果確認試験のまとめ]
高いアルカリ度を示す集排水の原液に対して,キレート効果,すなわち目詰まりの原因となる炭酸カルシウム(CaC03)で例えると,フルボ酸を添加することによって,結合状態のCaC03のカルシウムCaだけを切り離すことが可能となり,固まったCaC03が分離し,目詰まりの原因を防ぐことができる効果を持っているフルボ酸(フジミン「登録商標」)を利用することによって炭酸カルシウムの結晶粒子を分散させ,凝集する効果があることが確認できた。
[Summary of effect confirmation test]
For the undiluted solution of collected wastewater showing high alkalinity, chelating effect, that is, calcium carbonate (CaC0 3 ), which causes clogging, is compared by adding fulvic acid, so that only calcium Ca in the bound state CaC0 3 can be separated, the solidified CaC03 is separated, and the calcium carbonate crystal particles are dispersed by using fulvic acid (Fujimin “registered trademark”), which has the effect of preventing the cause of clogging. It has been confirmed that there is an effect of causing and aggregating.

この場合,pHが低下し過ぎると鋼材等の腐食が起こる可能性があることから,50倍程度に希釈したフルボ酸(フジミン「登録商標」)を珪藻土等の固形物に染み込ませた状態で高いアルカリ度(CaCO3)を示す集排水に接触させることによって,持続性を持って炭酸カルシウムの結晶粒子を分散させ,凝集する効果を発揮させることができる。 In this case, if the pH drops too much, corrosion of steel materials, etc. may occur. By contacting the collected wastewater with alkalinity (CaCO 3 ), it is possible to sustainably disperse and agglomerate the crystal particles of calcium carbonate.
