Description

本発明は、河川や用・排水路等公共用水域の排水を浄化処理する廃水処理装置及び排水処理施設に関する。   The present invention relates to a wastewater treatment apparatus and a wastewater treatment facility for purifying wastewater in public water bodies such as rivers and water / drainage channels.

例えば、下水道工事等では、地下水が湧出すると、ポンプアップして側溝に排水して処理している。
近年では、その様な湧出した地下水を側溝へ排出した場合にも、一定の水質基準をクリアすることが、要求されており、近い将来、施工における規制となることが予想される。
例えば、「浮遊物質量(SS)が180mg/リットル(日間平均150mg/リットル)」という基準を満たしたものだけを排水する義務が、施工業者に課せられるのである。
For example, in sewage works, when groundwater springs up, it is pumped up and drained into a gutter for treatment.
In recent years, it has been required to clear certain water quality standards even when such groundwater discharged is discharged into the gutter, and it is expected that it will become a regulation in construction in the near future.
For example, the duty of draining only those that satisfy the standard “the amount of suspended solids (SS) is 180 mg / liter (daily average 150 mg / liter)” is imposed on the contractor.

係る基準を充足するために、下水道工事等のコストが上昇しないように、簡易で且つ確実に、排水中の浮遊物質を除去出来る技術が望まれるに至った。
しかし、従来は、排水中の浮遊物質の様な微細な粒子は、巨大な施設を用いないと除去できなかったので、下水工事等の比較的規模が小さい工事現場における排水中の浮遊物質の処理は困難であった。
In order to satisfy such standards, a technique capable of easily and reliably removing suspended solids from wastewater has been desired so as not to increase the cost of sewerage work.
However, in the past, fine particles such as suspended solids in wastewater could not be removed without using a huge facility, so the treatment of suspended solids in wastewater at a relatively small construction site such as sewage works. Was difficult.

その他の従来技術として、例えば、排水中に浮遊している浮遊物質を放射状の糸体に付着させて増粒し、嫌気状態にせしめて、微生物により浮遊物質を消化させて減量し、その後、濾過槽で汚泥を分離する技術が提案されている(特許文献1)。
しかし、係る技術では微生物による処理が前提となるので、浮遊物質を減量するのに長時間を必要とする。そのため、比較的工期が短い下水道工事等では十分に機能を発揮することが出来ない、という問題を有している。
特開2002−224504号公報
As other conventional technologies, for example, the suspended solids suspended in the wastewater are attached to the radial thread body to increase the particle size, make it anaerobic, digest the suspended solids by microorganisms, reduce the amount, and then filter A technique for separating sludge in a tank has been proposed (Patent Document 1).
However, since such technology is premised on treatment with microorganisms, it takes a long time to reduce suspended solids. For this reason, there is a problem that the sewerage work with a relatively short construction period cannot sufficiently function.
JP 2002-224504 A

本発明において、投入装置(撹拌槽3A)で吸着性及び凝集性を兼ね備えた材料を投入する様に構成すれば(請求項3の発明)、凝集剤を添加して撹拌することが不要となるので、吸着材が投入された排水に凝集剤(例えば、2液タイプの凝集剤)を添加する凝集剤添加装置(A液定量ポンプ5と、B液定量ポンプ6)と、凝集剤が添加された排水を撹拌する撹拌装置(ラインミキサー7)とが不要となる。
その結果、装置の構成が簡略化される。
In the present invention, if the charging device (stirring tank 3A) is configured to input a material having both adsorptivity and aggregability (the invention of claim 3), it is not necessary to add and agitate the aggregating agent. Therefore, a flocculant addition device (A liquid metering pump 5 and B liquid metering pump 6) for adding a flocculant (for example, a two-liquid type flocculant) to the waste water into which the adsorbent is charged, and the flocculant are added. Therefore, a stirrer (line mixer 7) for stirring the waste water is not required.
As a result, the configuration of the apparatus is simplified.

以下、添付図面を参照して、本発明の実施形態について説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

先ず、図1〜図5を参照して第1実施形態を説明する。   First, a first embodiment will be described with reference to FIGS.

図1において、第1実施形態の排水処理装置は、異物除去装置であるゴミ等粗取り装置2と、撹拌槽3と、第1及び第2の凝集材添加装置5(A液添加装置),6(B液添加装置)と、ラインミキサー7と、沈殿装置8と、脱水装置9とを有している。   In FIG. 1, the wastewater treatment apparatus of the first embodiment includes a dust removing apparatus 2 that is a foreign substance removal apparatus, a stirring tank 3, and first and second agglomerate addition apparatuses 5 (A liquid addition apparatus), 6 (B liquid addition device), a line mixer 7, a precipitation device 8, and a dehydration device 9.

ゴミ等粗取り装置2は、傾斜型スクリーン21と固形物貯留槽22と排水槽23と排出ポンプP2を備えており、例えば、下水道工事等の施工現場1において、排水管T0から排出された排水が一旦側溝Cに流され、その側溝Cに流された固形物や汚泥を含む排水をポンプP1で排水管T1に汲み取り、排水管T1を介して送られる排水が、前記傾斜型スクリーン21の頂上近傍に形成された排水投入口24に投入される。
ここで、傾斜型スクリーン21に変えて、例えば「篩」や「ドラムスクリーン」を使用することも可能である。
The roughing device 2 for dust etc. includes an inclined screen 21, a solid material storage tank 22, a drainage tank 23, and a discharge pump P2. For example, drainage discharged from the drain pipe T0 in a construction site 1 such as sewerage construction. Is drained to the drainage pipe T1 by the pump P1 and the drainage sent through the drainage pipe T1 is drained to the top of the inclined screen 21. It is introduced into a drainage inlet 24 formed in the vicinity.
Here, instead of the inclined screen 21, for example, “sieving” or “drum screen” can be used.

排水投入口24に投入された排水は、図示しない搬送手段で、傾斜型スクリーン21に押出され、そのスクリーン21に押出された固形物や汚泥を含む排水のうち、水分及び微細な浮遊物がスクリーンの網目から、スクリーン直下に形成された排水槽23に滴下して貯留される。
スクリーン21から滴下されない固形部分及び汚泥は傾斜型スクリーン21上を滑り降り、傾斜型スクリーン21の下方に連なる固形物貯留槽22に落下して貯留される。
固形物貯留槽22に貯留された固形部分及び汚泥は一定量貯めた後、分別されてリサイクル出来る部分についてはリサイクルする。
Wastewater thrown into the drainage inlet 24 is extruded to the inclined screen 21 by a conveying means (not shown). Among the wastewater containing solid matter and sludge pushed onto the screen 21, moisture and fine floating matter are screened. From this mesh, it is dropped and stored in a drainage tank 23 formed immediately below the screen.
The solid portion and sludge not dripped from the screen 21 slide down on the inclined screen 21 and are dropped and stored in the solid storage tank 22 connected below the inclined screen 21.
A certain amount of the solid portion and sludge stored in the solid matter storage tank 22 are stored, and then the portion that can be separated and recycled is recycled.

排水槽23に貯留された水分、即ち、異物が除去された排水は、搬出ポンプP2を駆動することにより、排水管T2を経由して撹拌層3に送られる。   The water stored in the drain tank 23, that is, the waste water from which the foreign matter has been removed, is sent to the stirring layer 3 via the drain pipe T2 by driving the carry-out pump P2.

撹拌槽3は隔壁31によって撹拌室32と、そうでない室33に分けられ、撹拌室32には撹拌機34が、撹拌室でない室33には排水搬出用のポンプP3が装備されている。尚、隔壁31の下方では二つの部屋32,33は連通している。   The agitation tank 3 is divided by a partition wall 31 into an agitation chamber 32 and a chamber 33 that is not, and the agitation chamber 32 is equipped with a stirrer 34, and the chamber 33 that is not an agitation chamber is equipped with a pump P3 for carrying out drainage. Note that the two chambers 32 and 33 communicate with each other below the partition wall 31.

撹拌槽3の上方には、吸着剤投入機(バイオカーボン定量供給機)4が配置されている。吸着剤投入機(バイオカーボン定量供給機)4は、吸着性及び凝集性を兼ね備えた吸着剤を受入れ貯留するホッパ41と、撹拌槽3に吸着剤を投入する投入口42と、ホッパ41内の吸着剤を投入口42に送り出す搬送スクリュー43とを有している。投入口42は、撹拌槽3の撹拌機を装備した撹拌室32の真上に位置している。   Above the agitation tank 3, an adsorbent charging machine (biocarbon quantitative supply machine) 4 is arranged. The adsorbent charging device (biocarbon quantitative supply device) 4 includes a hopper 41 that receives and stores an adsorbent having both adsorptivity and aggregability, an input port 42 that inputs the adsorbent into the agitation tank 3, It has a conveying screw 43 that sends out the adsorbent to the inlet 42. The charging port 42 is located directly above the stirring chamber 32 equipped with the stirrer of the stirring tank 3.

撹拌槽3に注入された異物の除去された排水に上方の吸着剤投入機4から吸着剤が投入され、その状態の排水を撹拌機34で撹拌する。   The adsorbent is introduced from the upper adsorbent dispenser 4 into the wastewater from which foreign matter has been poured into the stirring tank 3, and the wastewater in this state is agitated by the agitator 34.

ここで、吸着剤投入機4から撹拌槽3に投入される、吸着性及び凝集性を兼ね備えた吸着剤とは、動植物性残渣を高温加熱して生成した炭化物(微粉炭)である。
そして、凝集剤(微粉炭)の添加量が一定比率となる様に、異物除去装置2の排水槽23や撹拌槽3のレベルをチェックして、異物除去装置2のポンプP2、撹拌槽3のポンプP3を作動させる。
Here, the adsorbent having both adsorptivity and agglomeration charged into the agitation tank 3 from the adsorbent charging device 4 is a carbide (pulverized coal) generated by heating animal and plant residues at a high temperature.
And the level of the drainage tank 23 of the foreign material removal apparatus 2 and the stirring tank 3 is checked so that the addition amount of the flocculant (pulverized coal) becomes a constant ratio, and the pump P2 and the stirring tank 3 of the foreign material removal apparatus 2 are checked. The pump P3 is activated.

吸着剤を添加され、撹拌された状態の排水は搬送ポンプP3によって配管T3に送り出され、ラインミキサー7の最下端の第1の流入口71に送り込まれる。   The wastewater in the state where the adsorbent is added and stirred is sent to the pipe T3 by the transport pump P3 and sent to the first inlet 71 at the lowermost end of the line mixer 7.

ラインミキサー7には、前記第1の流入口71の上方に第2の流入口72、更にその上方に第3の流入口73が形成されている。第2の流入口72は第1の凝集剤添加装置(A液定量ポンプ)5(の配管T5)と連通し、第3の流入口73は第2の凝集剤添加装置(B液定量ポンプ)6(の配管T6)と連通している。   In the line mixer 7, a second inlet 72 is formed above the first inlet 71, and a third inlet 73 is formed above the second inlet 72. The second inflow port 72 communicates with the first flocculant addition device (A liquid metering pump) 5 (the pipe T5), and the third inflow port 73 is the second flocculant addition device (B liquid metering pump). 6 (the pipe T6).

第1の凝集剤添加装置(A液定量ポンプ)5は、第1の凝集剤であるA液を貯留するA液タンク51と配管T5と搬送ポンプP5とで構成され、第2の凝集剤添加装置(B液定量ポンプ)6は、第2の凝集剤であるB液を貯留するB液タンク61と撹拌機62と配管T6と搬送ポンプP6とで構成されている。   The first flocculant addition device (A liquid metering pump) 5 includes an A liquid tank 51 for storing liquid A, which is the first flocculant, a pipe T5, and a transport pump P5. The apparatus (B liquid metering pump) 6 includes a B liquid tank 61 that stores B liquid as the second flocculant, a stirrer 62, a pipe T6, and a transport pump P6.

ここで、排水に添加される前記吸着剤は、排水中の未だ除去されぬ細かな異物を吸着剤に吸着させる。そして、凝集剤A液、B液は、異物を吸着させた吸着剤を凝集させ、排水の水から、凝集した異物を遊離させ、以下に詳述する沈殿装置8の底に沈殿させる。   Here, the adsorbent added to the wastewater causes the adsorbent to adsorb fine foreign matters in the wastewater that have not yet been removed. And the coagulant | flocculant A liquid and B liquid aggregate the adsorbent which adsorb | sucked the foreign material, liberate the aggregated foreign material from the waste water, and make it settle on the bottom of the precipitation apparatus 8 explained in full detail below.

沈殿装置8は、凝集沈殿槽81と、凝集沈殿槽81の上方を覆う天蓋82と、凝集沈殿槽81の下部に設けた沈殿物搬送スクリュー83と、その搬送スクリュー83を駆動するモータ84とを有している。凝集沈殿槽81の上部には、排水の上澄採取口85aを有する上澄採取樋85が設けられ、その吐出口85bは凝集沈殿槽81の外部に突出している。   The sedimentation apparatus 8 includes a coagulation sedimentation tank 81, a canopy 82 that covers the top of the coagulation sedimentation tank 81, a sediment conveyance screw 83 provided in the lower part of the aggregation precipitation tank 81, and a motor 84 that drives the conveyance screw 83. Have. In the upper part of the coagulation sedimentation tank 81, a supernatant collection bowl 85 having a supernatant collection port 85a for drainage is provided, and the discharge port 85b protrudes outside the coagulation sedimentation tank 81.

凝集沈殿槽81内部の上方には、上澄採取樋85の配置された領域とそうでない領域とを隔てる隔壁86が形成されている。
又、天蓋82において上澄採取樋85の配置されていない領域を覆う部分には、投入口82aが形成されている。その投入口82aにはラインミキサー7に連通する配管T7の一端が接続され、ラインミキサー7からの、吸着剤の混じった排水と2種の凝集剤(A液、B液)とが混合された状態の液体が凝集沈殿槽81内に投入される。
前記隔壁86は、吸着剤、凝集剤の混じった排水が投入口82aから投入された場合に、その影響が上澄の採取に影響を及ぼさない機能を果たしている。
A partition wall 86 is formed above the inside of the coagulation sedimentation tank 81 to separate the region where the supernatant collection bowl 85 is disposed from the region where it is not.
An inlet 82a is formed in a portion of the canopy 82 that covers a region where the supernatant collection bowl 85 is not disposed. One end of a pipe T7 communicating with the line mixer 7 is connected to the input port 82a, and the waste water mixed with the adsorbent from the line mixer 7 and two kinds of flocculants (A liquid and B liquid) are mixed. The liquid in a state is charged into the coagulation sedimentation tank 81.
The partition wall 86 functions to prevent the supernatant from being collected when drainage mixed with an adsorbent and a flocculant is introduced from the inlet 82a.

凝集沈殿槽81に投入された排水は、吸着剤によって先ず排水中の異物を吸着させ、その異物を吸着させた吸着剤ごと2液の凝集剤によって、凝集し沈殿して、上澄み水Lと沈殿物Sとに分離される。
すなわち、凝集沈澱槽81へ供給される混合液(微細な異物を含んだ水と、凝集剤A液・B液、及び微粉炭或いはケミカルカーボン、との混合液)内は圧力が高く、その内部に生じる塊は当該高い圧力が作用しているが、混合液が凝集沈澱槽81へ供給されると、当該圧力が開放される。その結果、異物が凝縮した塊は瞬時に膨張するので、凝集沈澱槽81に斜板を設けなくても、即時に沈澱する。
The wastewater charged into the coagulation sedimentation tank 81 is first adsorbed by the adsorbent foreign matter in the wastewater, and the adsorbent adsorbing the foreign matter is agglomerated and precipitated by the two liquid flocculant, and the supernatant water L and the precipitate are precipitated. The product S is separated.
In other words, the pressure in the mixed liquid (mixed liquid of water containing fine foreign matters, coagulant A liquid / B liquid, and pulverized coal or chemical carbon) supplied to the coagulation sedimentation tank 81 is high, The high pressure acts on the lump produced in (1), but when the mixed solution is supplied to the coagulation sedimentation tank 81, the pressure is released. As a result, the lump in which the foreign matter is condensed expands instantaneously, so that it is immediately precipitated without providing a swash plate in the coagulating sedimentation tank 81.

凝集沈澱槽81における上澄み水Lが、一定のレベルに到達すると、上澄樋85内に流入し、上澄槽10に排出される。更に、上澄槽10に一時貯留された上澄み水は一定量溜まると自動的に揚水ポンプP10で配管T10を介してPH調整槽11に搬送される。   When the supernatant water L in the coagulation sedimentation tank 81 reaches a certain level, it flows into the supernatant bowl 85 and is discharged into the supernatant tank 10. Furthermore, when a certain amount of the supernatant water temporarily stored in the supernatant tank 10 is accumulated, it is automatically conveyed to the PH adjustment tank 11 by the pumping pump P10 via the pipe T10.

尚、上澄み水は沈殿装置8で、異物が沈殿して分離されているので、浮遊物質についてのレベルはクリアしており、排水しても自然環境に悪影響を与えないので、そのまま下水溝等に放流しても良く、自然環境に悪影響を及ぼすこともない。
しかし、上澄槽10に溜められた上澄み水が、PHに関する環境基準をクリアしていない場合には、図1に示すように、PH調整槽11でPH調整した後に排水する。
In addition, since the supernatant water is settled and separated by the sedimentation device 8, the level of suspended solids is clear, and even if drained it does not adversely affect the natural environment. May be released and will not adversely affect the natural environment.
However, when the supernatant water stored in the supernatant tank 10 does not satisfy the environmental standards related to PH, as shown in FIG.

一方、沈殿物Sは搬送用スクリュー83によって凝集沈殿槽81外の配管T8に送り出される。そして配管T8に送り出された沈殿物は搬送ポンプP8によって、脱水装置(袋重力脱水ユニット)9側の投入口92aに送られる。
ここで、搬送用スクリュー83を用いて、凝集沈澱槽81の沈澱物を脱水装置(袋重力脱水ユニット)9側へ搬送することにより、凝集沈澱槽81の底部で沈澱物(汚泥)表面が均一となる。また、沈澱物(汚泥)Sが浮き上がってしまうことが防止できる。
On the other hand, the precipitate S is sent out to the pipe T8 outside the coagulating sedimentation tank 81 by the conveying screw 83. And the deposit sent out to the piping T8 is sent to the inlet 92a at the side of the dehydrating device (bag gravity dehydrating unit) 9 by the transport pump P8.
Here, the precipitate (sludge) surface is uniform at the bottom of the coagulation sedimentation tank 81 by conveying the precipitate in the coagulation sedimentation tank 81 to the dehydrating device (bag gravity dehydration unit) 9 side using the conveying screw 83. It becomes. Moreover, it can prevent that the deposit (sludge) S floats up.

脱水装置(袋重力脱水ユニット)9は、滴下水槽91と、滴下水槽91の上方に配置され一端が前記投入口92aであって中間部に複数の分配口92bを有する分岐管92と、分配口92bの先端毎に設けた開閉弁93と、複数の重力脱水袋94と、揚水ポンプP9とによって構成されている。
重力脱水袋94は、図示しない吊り下げ手段によって分岐管92に吊るされ、袋の開口部が前記開閉弁93の直下に位置する様に配置される。
The dewatering device (bag gravity dewatering unit) 9 includes a dropping water tank 91, a branch pipe 92 disposed above the dropping water tank 91, one end of which is the charging port 92a and a plurality of distribution ports 92b in the middle, and a distribution port The opening / closing valve 93 provided for each tip of 92b, a plurality of gravity dewatering bags 94, and a pumping pump P9.
The gravity dewatering bag 94 is suspended from the branch pipe 92 by a suspension means (not shown), and is disposed so that the opening of the bag is located directly below the on-off valve 93.

投入口92aに投入された沈殿物は、分配口92bの先端毎に設けた開閉弁93から、重力脱水袋94内に投入される。
脱水装置(袋重力脱水ユニット)9は、重力脱水袋94内に所定の量の沈殿物が投入されると、図示しないセンサ(レベルセンサ、又は質量センサ)が所定量に達したことを検知して、自動的に開閉弁93を閉鎖し、沈殿装置8側のスクリュー83及び/又は搬送ポンプP8を停止させる様に制御している。
この制御については、図5を参照して後述する。
沈殿物の投入量が所定量に達した重力脱水袋94はそのままの状態で所定時間放置され(沈殿物自体の重量で脱水している)、或いは、図示しない振動付与手段によって重力脱水袋に振動が加えられて、脱水が行われる。
尚、上記した袋重力脱水ユニットではなく、種々の脱水手段を用いることも可能である。脱水手段の決定に際しては、施工現場の状況や施主の要請等を勘案して決めればよい。
The sediment introduced into the introduction port 92a is introduced into the gravity dehydration bag 94 from an on-off valve 93 provided at each end of the distribution port 92b.
When a predetermined amount of sediment is put into the gravity dewatering bag 94, the dehydrating device (bag gravity dehydrating unit) 9 detects that a sensor (level sensor or mass sensor) (not shown) has reached a predetermined amount. Thus, the on-off valve 93 is automatically closed and the screw 83 and / or the conveyance pump P8 on the sedimentation device 8 side is controlled to stop.
This control will be described later with reference to FIG.
The gravity dewatering bag 94 whose amount of deposit has reached a predetermined amount is left as it is for a predetermined time (dehydrated by the weight of the precipitate itself) or vibrated in the gravity dewatering bag by a vibration applying means (not shown). Is added for dehydration.
Note that various dewatering means can be used instead of the above-described bag gravity dewatering unit. In determining the dehydration means, it may be determined in consideration of the situation at the construction site and the request of the owner.

脱水の完了した重力脱水袋94は図示しない搬送手段によって脱水装置(袋重力脱水ユニット)9外に搬送され、リサイクル、例えば、園芸用土等に活用される。   The gravity dehydration bag 94 that has been dehydrated is conveyed outside the dehydration device (bag gravity dehydration unit) 9 by a conveying means (not shown), and is used for recycling, for example, gardening soil.

滴下水槽91に貯留された水は、放流の規準を満たしていればそのまま放流することが出来るが、PHに関する環境基準のみをクリアしていない場合には、揚水ポンプP9によって配管T9を介してPH調整槽11に搬送される。
一方、滴下水槽91に貯留された水が、放流の規準を満たしていなければ図示はしないが、前述の撹拌槽3にその水を戻し、再び撹拌槽3による工程から以降の工程を繰り返す。
The water stored in the dropping water tank 91 can be discharged as long as it satisfies the discharge standard. However, if only the environmental standard related to PH is not cleared, the water is pumped through the pipe T9 by the pumping pump P9. It is conveyed to the adjustment tank 11.
On the other hand, if the water stored in the dripping water tank 91 does not satisfy the discharge standard, the water is returned to the agitation tank 3 described above, and the subsequent processes from the process by the agitation tank 3 are repeated again.

PH調整槽11は隔壁110によって撹拌室120とそうでない室130とに分けられ、撹拌室120には撹拌機140が装備されている。又、撹拌室120にはPH中和剤添加装置150からPH中和剤が添加されるように構成されている。
撹拌室でない室130には放流口130aが形成され、PH中和処理されたきれいな水は、その放流口からシステム外に放流される。
The PH adjustment tank 11 is divided into a stirring chamber 120 and a chamber 130 that is not so by a partition wall 110, and the stirring chamber 120 is equipped with a stirrer 140. The stirring chamber 120 is configured such that a PH neutralizer is added from a PH neutralizer addition device 150.
A discharge port 130a is formed in the chamber 130 which is not a stirring chamber, and clean water subjected to PH neutralization treatment is discharged from the discharge port to the outside of the system.

次に図2及び図3を参照して、本発明の排水処理装置の実際の構成について説明する。
図2は、排水処置装置全体を示した側面配置図である。 又、図3は図2を立体的に表した斜視図である。

第3のユニットU3は、図1における脱水装置9で構成されている。
尚、図2、図3では、図1及び図4における上澄槽10は図示を省略しており、図4におけるPH調整槽11の図示も省略している。
Next, with reference to FIG.2 and FIG.3, the actual structure of the waste water treatment apparatus of this invention is demonstrated.
FIG. 2 is a side view showing the entire drainage treatment apparatus. FIG. 3 is a perspective view showing FIG. 2 in three dimensions.
2 and 3, the waste water treatment apparatus is composed of three large units U1, U2 and U3.
2 and 3 that are not particularly described below are the same as those in FIG. 1 and the components thereof.
The first unit U1 is composed of a dust roughing device 2, which is a foreign matter removing device in FIG. 1, a stirring tank 3, and an adsorbent charging device 4.
The second unit U2 includes the flocculant addition devices 5 and 6 in FIG. 1, a line mixer 7 that is a stirring device, a precipitation device 8, and a supernatant tank 10. A symbol Fp in the unit U2 indicates a flange for connecting the transfer pump.
The third unit U3 includes the dehydrating device 9 in FIG.
2 and 3, illustration of the supernatant tank 10 in FIGS. 1 and 4 is omitted, and illustration of the PH adjustment tank 11 in FIG. 4 is also omitted.

図4は、図1で示す排水処理フローを、さらに模式的に示したブロック図である。図4に基づいて、再度、廃水処理の流れを簡単に説明する。
先ず、作業現場1で採取された処理されるべき排水は、ゴミ等粗取り装置2に送られ(R1)、ゴミ等粗取り装置2で、固形部分等が分別されリサイクルに回される(R2)。固形物等が除去された排水は撹拌槽3に送られ(R3)、吸着剤投入機であるバイオカーボン定量供給機4によって吸着剤が添加され(R4)、撹拌される。
吸着剤が添加された排水はラインミキサー7に送られ(R5)、A液定量ポンプ5から添加(R6)されたA液(凝集剤)と、B液定量ポンプ5から添加(R7)されたB液(凝集剤)と、混合され沈殿装置8の凝集沈殿槽81に送られる(R8)。
沈殿装置8では、異物が除去された状態の上澄み水が上澄槽10に排出され(R9)、その後必要に応じて(R10)PH調整槽11でPH処理されて、例えば、図示しない下水溝に放流される(R11)。
一方、沈殿物は脱水装置である袋重力脱水ユニット9に送られ(R12)、脱水処理されて、固形物がリサイクルに回される(R13)。袋重力脱水ユニット9で滴下して溜められた濾液水はPH調整槽11に送られ(R14)、PH調整槽11でPH処理されて、例えば、下水溝に放流される(R11)。
FIG. 4 is a block diagram schematically showing the wastewater treatment flow shown in FIG. Based on FIG. 4, the flow of wastewater treatment will be briefly described again.
First, the wastewater to be treated collected at the work site 1 is sent to the roughing device 2 for dust and the like (R1), and the solid portion etc. is separated and recycled for recycling by the roughing device 2 for dust and the like (R2). ). The waste water from which the solids and the like have been removed is sent to the agitation tank 3 (R3), and the adsorbent is added (R4) by the biocarbon quantitative supply device 4 which is an adsorbent charging machine and stirred.
The waste water to which the adsorbent was added was sent to the line mixer 7 (R5), and was added from the A liquid (flocculating agent) added from the A liquid metering pump 5 (R6) and added from the B liquid metering pump 5 (R7). It mixes with B liquid (flocculating agent), and is sent to the coagulation sedimentation tank 81 of the precipitation apparatus 8 (R8).
In the sedimentation device 8, the supernatant water from which foreign matters have been removed is discharged to the supernatant tank 10 (R9), and then subjected to PH treatment in the PH adjustment tank 11 as necessary (R10). (R11).
On the other hand, the precipitate is sent to the bag gravity dehydration unit 9 which is a dehydrator (R12), dehydrated, and the solid matter is recycled (R13). The filtrate water dripped and stored in the bag gravity dehydration unit 9 is sent to the PH adjustment tank 11 (R14), subjected to PH treatment in the PH adjustment tank 11, and discharged into, for example, a sewer (R11).

次に、図5を参照して、脱水装置(袋重力脱水ユニット)9における、重力脱水袋94の自動投入停止制御について説明する。   Next, with reference to FIG. 5, the automatic charging / stopping control of the gravity dewatering bag 94 in the dewatering device (bag gravity dewatering unit) 9 will be described.

先ず、例えば、図示しないレベルセンサによって重力脱水袋への沈殿物の投入状態を検知しており(ステップS1)、図示しない制御手段(例えばコントロールユニット)は沈殿物の投入量が所定量に達したか否かを判断する(ステップS2)。   First, for example, a level sensor (not shown) detects the state of depositing into the gravity dewatering bag (step S1), and the control means (eg, control unit) (not shown) has reached a predetermined amount of deposit. Whether or not (step S2).

沈殿物の投入量が所定量に達した場合(ステップS2のYES)は、開閉弁94を閉鎖し、搬送スクリュー83を停止(ステップS)した後、リセットして(ステップS5)、ステップS6に進む。   When the amount of deposit input reaches a predetermined amount (YES in step S2), the on-off valve 94 is closed, the conveying screw 83 is stopped (step S), and then reset (step S5). move on.

一方、沈殿物の投入量が所定量に達していない場合(ステップS2のNO)は、袋94内への沈殿物投入を続行しつつ、ステップS2に戻り、ステップS2以降を繰り返す。   On the other hand, when the amount of deposit input has not reached the predetermined amount (NO in step S2), the procedure returns to step S2 while continuing the deposit input into the bag 94, and repeats step S2 and subsequent steps.

ステップS6では、図示せぬ制御手段は制御を終了するか否かを判断して、終了するのであれば(ステップS6のYES)、そのまま終了し、未だ制御を続行するのであれば(ステップS6のNO)、ステップS1まで戻り、再びステップS1以降を繰り返す。   In step S6, the control means (not shown) determines whether or not to end the control. If the control is to be ended (YES in step S6), the control is ended as it is and if the control is still continued (in step S6). NO), return to step S1, and repeat step S1 and subsequent steps again.

上述した第1実施形態によれば、排水中に混合されている異物(例えば、ゴミ、土塊等)がゴミ等粗取り装置2により除去され、異物が除去された排水に吸着材である微粉炭が添加され、吸着材と凝集剤とにより塊となった浮遊物質等の異物が沈澱装置の凝集沈殿槽81で沈澱する様に構成されているので、浮遊物質等の異物が排水中から効率的に分離され、浮遊物質に関する各種規制をクリアすることが可能となる。そして、従来技術の様に、微生物により消化させる場合等に比較して、短時間で浮遊物質等が排水から分離されるので、施工期間が比較的短い工事についても、適用が可能である。   According to the above-described first embodiment, foreign matter (for example, dust, lump, etc.) mixed in the wastewater is removed by the roughing device 2 such as dust, and the pulverized coal that is an adsorbent in the wastewater from which the foreign matter has been removed. Is added, and foreign substances such as floating substances agglomerated by the adsorbent and the aggregating agent are precipitated in the coagulating sedimentation tank 81 of the precipitation device. It becomes possible to clear various regulations concerning suspended solids. Then, as in the prior art, the suspended matter and the like are separated from the wastewater in a shorter time than when digested by microorganisms, and therefore, the present invention can be applied to a construction with a relatively short construction period.

また、3つのユニット(U1〜U3)として構成することが可能であるので各ユニット単位で施工現場に搬送することが容易であり、且つ、ユニット間の配管作業を行うだけで、施工現場で容易に排水処理装置を組み立てることが可能である。即ち、従来技術に比べ工期を大幅に短縮出来る。   In addition, since it can be configured as three units (U1 to U3), it is easy to transport each unit to the construction site, and it is easy at the construction site by simply performing piping work between the units. It is possible to assemble a wastewater treatment device. That is, the construction period can be greatly shortened as compared with the prior art.

次に、図6を参照して第2実施形態について説明する。
図6の第2実施形態は、バイオカーボン定量供給機4Aにおいて、微粉炭に代えて、いわゆる「ケミカルカーボン」を使用する実施形態である。この「ケミカルカーボン」は、微粉炭と同様に微小な異物を吸着すると共に、非常に良好な凝集性能を発揮するので、凝集剤は不要となる。
そこで、第1実施形態で装備されたA液定量ポンプ5と、B液定量ポンプ6と、ラインミキサー7も省略出来る。
Next, a second embodiment will be described with reference to FIG.
The second embodiment of FIG. 6 is an embodiment in which so-called “chemical carbon” is used in place of pulverized coal in the biocarbon quantitative supply machine 4A. Since this “chemical carbon” adsorbs minute foreign matters as well as pulverized coal and exhibits very good aggregating performance, an aggregating agent is not required.
Therefore, the liquid A metering pump 5, the liquid B metering pump 6, and the line mixer 7 provided in the first embodiment can be omitted.

ここで、「ケミカルカーボン」とは、特開2005−21783号公報で開示されている環境汚染防止用薬剤である。
すなわち、「ケミカルカーボン」は、動植物性残渣を高温加熱して生成した炭化物と、アクリル系水溶性高分子材料との混合物を粉体状に構成し、アクリル系水溶性高分子材料はイオン性水溶性モノマーの重合体であるか、或いは、イオン性水溶性モノマーと非イオン性水溶性モノマーの共重合であり、アクリル系水溶性高分子材料の添加量は、動植物性残渣を高温加熱して生成した炭化物の1%〜50%である。
Here, “chemical carbon” is a chemical for preventing environmental pollution disclosed in Japanese Patent Application Laid-Open No. 2005-21783.
In other words, “chemical carbon” is a powdery mixture of carbides produced by heating animal and plant residues at high temperatures and acrylic water-soluble polymer materials. Acrylic water-soluble polymer materials are ionic water-soluble materials. It is a polymer of an ionic monomer or is a copolymer of an ionic water-soluble monomer and a non-ionic water-soluble monomer, and the addition amount of the acrylic water-soluble polymer material is generated by heating animal and plant residues at high temperature 1% to 50% of the resulting carbide.

以下、図6に基づいて、第1実施形態の構成と異なる部分を主体に説明する。   Hereinafter, based on FIG. 6, it demonstrates mainly on a different part from the structure of 1st Embodiment.

第1実施形態と同様のゴミ等粗取り装置2から排出された排水は、排水管T2によって撹拌槽3Aに投入される様に構成されている。     The waste water discharged from the same rough dust removing device 2 as in the first embodiment is configured to be put into the stirring tank 3A through the drain pipe T2.

撹拌槽3Aは、隔壁31によって二つの室32A,33に分けられ、撹拌室32Aには撹拌機34Aが、室33には排水搬出用ポンプP3が装備されている。尚、隔壁31の下方では二つの部屋32A,33は連通している。 The stirring tank 3A is divided into two chambers 32A and 33 by a partition wall 31. The stirring chamber 32A is equipped with a stirrer 34A, and the chamber 33 is equipped with a drainage pump P3. Note that the two rooms 32A and 33 communicate with each other below the partition wall 31.

撹拌機3Aの上方には、バイオカーボン定量供給機4Aが配置されている。バイオカーボン定量供給機4Aは、吸着性及び凝集性を兼ね備えた吸着剤である「ケミカルカーボン」を受入れ貯留するホッパ41Aと、撹拌槽3Aに吸着剤「ケミカルカーボン」を投入する投入口42Aと、ホッパ41A内の吸着剤「ケミカルカーボン」を投入口42Aに送り出す搬送スクリュー43Aとを有している。投入口42Aは、撹拌槽3Aの撹拌機34Aを装備した部屋32Aの真上に位置している。   Above the stirrer 3A, a biocarbon quantitative feeder 4A is arranged. The biocarbon quantitative supply machine 4A includes a hopper 41A that receives and stores "chemical carbon" that is an adsorbent having both adsorptivity and aggregability, and an inlet 42A that inputs the adsorbent "chemical carbon" to the stirring tank 3A. It has a conveying screw 43A that feeds the adsorbent “chemical carbon” in the hopper 41A to the inlet 42A. The inlet 42A is located directly above the room 32A equipped with the stirrer 34A of the stirring tank 3A.

前記排水搬出用ポンプP3には排水管T3Aが接続され、その排水管T3Aの他端は、沈殿装置8の投入口81aに連通する様に構成されている。   A drain pipe T3A is connected to the drainage pump P3, and the other end of the drain pipe T3A is configured to communicate with the inlet 81a of the precipitation device 8.

沈殿装置8及び、それ以降の装置に関しては、図1の第1実施形態の構成と同様であり、以降の説明を省略する。 The precipitation device 8 and the subsequent devices are the same as those of the first embodiment shown in FIG.

上述した第2実施形態によれば、撹拌槽3Aで吸着性及び凝集性を兼ね備えた材料(例えば、ケミカルカーボン)を投入する様に構成しており、凝集剤を添加して撹拌することが不要となり、2液タイプの凝集剤を添加する凝集剤添加装置(例えばA液定量ポンプと、B液定量ポンプ)と、凝集剤が添加された排水を撹拌するラインミキサー7とが不要となる。   According to the second embodiment described above, the stirring tank 3A is configured such that a material having both adsorptivity and aggregability (for example, chemical carbon) is added, and it is not necessary to add and agitate the aggregating agent. Thus, the flocculant addition device (for example, the liquid A metering pump and the liquid B metering pump) for adding the two-liquid type flocculant and the line mixer 7 for stirring the waste water to which the flocculant has been added are unnecessary.

図示の実施形態はあくまでも例示であり、本発明の技術的範囲を限定する趣旨の記述ではない旨を付記する。   It should be noted that the illustrated embodiment is merely an example, and is not a description to limit the technical scope of the present invention.
