The present invention relates to an invention that enables high concentration flocculation treatment while increasing flow rate at low flow rates, and at the same time improves the purification efficiency.

일반적으로 공사현장 즉, 터널공사 현장에서는 터널을 굴착하는 중에 건수 및 지하수와 같은 물이 공사중인 터널 내부에 발생하게 된다.In general, at the construction site, that is, the tunnel construction site, water such as dry water and groundwater is generated inside the tunnel under construction during the excavation of the tunnel.

상기와 같이 터널공사 현장에서 발생된 물에는 굴삭중에 발생하는 토사가 유입되어 탁해진다.As described above, the water generated at the tunnel construction site is infiltrated by turbidity generated during excavation.

상기와 같이 토사의 혼입으로 발행된 물을 정화하지 않고 하천으로 방류할 경우, 물에 하천 바닥에 토사가 퇴적되어 미생물의 생성 및 활동을 저하켜 하천수의 수질 악화를 초래 함은 물론 현탁물인 토사가 어류의 아가미를 막아 어류의 생육을 방해 할 뿐만 아니라, 심지어는 어류의 생육이 불가능 한 죽은 하천으로 변화시키게 된다.When discharged into the river without purifying the water issued by the incorporation of the soil as described above, the soil is deposited on the bottom of the river in the water to reduce the production and activity of microorganisms, leading to deterioration of the water quality of the river water, as well as the suspended soil It not only prevents the gills of fish and prevents them from growing, but even transforms them into dead rivers, where it is impossible to grow them.

상기한 문제점을 방지하기 위하여 터널공사 현장에서 발생되는 현탁수(이하 "처리수" 라 합니다)는 정화과정을 거쳐 방류하고 있고, 처리수를 정화하는 방법으로는 물에 혼입된 토사등과 같은 부유물을 침전시켜 처리수를 정화하는 침전방식의 폐수설비를 이용하게 된다.In order to prevent the above problems, suspended water (hereinafter referred to as "treated water") generated at the tunnel construction site is discharged through a purification process, and a method of purifying the treated water is suspended matter such as earth and sand mixed in water. Sedimentation is used to sedimentation wastewater facility to purify the treated water.

침전방식에 의해 현탁물이 혼입된 처리수의 부유물을 침전시키는 폐수설비는, 터널공사 현장으로부터 발생한 처리수내의 부유물을 침강 분리 시킴과 동시에 처리수내의 유해성 물질을 살균한 후, 여과 과정을 거쳐 여과된 맑은 물을 방류하게 된다.The wastewater facility for precipitating the suspended matter in the treated water in which the suspended matter is mixed by the sedimentation method sediments and separates the suspended matter in the treated water generated from the tunnel construction site, sterilizes the harmful substances in the treated water, and then passes the filtration process. Discharged clear water.

상기와 같이 터널공사 현장에서 발생한 처리수를 폐수설비를 이용하여 정화시키는 과정을 도1에 의해 구체적으로 설명하면 다음과 같다.The process of purifying the treated water generated at the tunnel construction site using the wastewater facility as described above will be described in detail with reference to FIG. 1.

터널공사 현장에서 발생한 처리수가 침사조(10)의 침사지(11)로 유입되어 돌과 같은 큰 입자의 부유물이 침강 분리되어진다.The treated water generated in the tunnel construction site is introduced into the settlement 11 of the sedimentation tank 10 so that large particles of suspended matter such as stones are sedimented and separated.

상기 침사조(10)의 침사지(11)에서 큰 입자의 부유물이 분리되어진 처리수는 집수조(12)로 유입되어지게 되고, 상기 집수조(12)로 유입되어진 처리수는 정량펌프(13)에 의해 펌핑되어 중화/반응조(20)로 공급된다.The treated water from which the large particles of suspended matter are separated from the settling basin 11 of the immersion tank 10 is introduced into the sump tank 12, and the treated water introduced into the sump tank 12 is provided by the metering pump 13. It is pumped and supplied to the neutralization / reactor 20.

이때 비중이 낮은 부유물은 농축조(30)로 보내져 처리되어진다.At this time, the float having a low specific gravity is sent to the concentration tank 30 to be processed.

중화/반응조(20)로 공급된 처리수는 교반날개(23)를 갖고 전동모터(21)에 의해 회전하는 교반축(22)의 회전으로 교반되어지게 되고, 상기와 같이 교반되어지는 처리수는 약제통(60)으로부터 공급된 황산과 섞여 처리수내에 포함되어 있는 세균성 유해물질이 살균되어지게 된다.The treated water supplied to the neutralization / reaction tank 20 is stirred by the rotation of the stirring shaft 22 rotating by the electric motor 21 with the stirring blade 23, and the treated water stirred as described above The bacterial harmful substances contained in the treated water are mixed with the sulfuric acid supplied from the medicine container 60 to be sterilized.

또한 약제통(70)으로부터 공급되어진 황산반토와 섞이면서 처리수내의 부유물이 1차응집되어지게 된다.In addition, the suspended solids in the treated water are first agglomerated while being mixed with the alumina sulfate supplied from the medicine container 70.

상기와 같이 1차응집되어진 부유물은 아래로 침강되어져 슬러지펌프(도면에 특정부호로 표시하지 않ㅎ았음)를 통해 수거되어지게 된다.As described above, the first flocculated suspended solids are settled down and collected through a sludge pump (not shown in the drawing).

상기 중화/반응조(20)에서 부유물이 1차응집되어 정화되어진 처리수는 중화/반응조(20)와 연결된 이송관(90)을 통해 침전조로 공급되어지게 된다.In the neutralization / reactor 20, the suspended solids are first agglomerated and purified to be supplied to the settling tank through the transfer pipe 90 connected to the neutralization / reactor 20.

상기 중화/반응조(20)에서 정화된 처리수가 이송관(90)을 따라 이송할때 이송관(90)에는 약제통(80)으로부터 고분자응집제가 투입되어져 중화/반응조(20)에서 응집되어지지 않은 처리수내의 미세 부유물이 2차응집되어지게 된다.When the treated water purified in the neutralization / reaction tank 20 is transported along the transfer pipe 90, the polymer coagulant is introduced into the transfer pipe 90 from the chemical container 80 so that it is not aggregated in the neutralization / reaction tank 20. Fine suspended matter in the treated water will be secondary agglomerated.

상기 고분자응집제에 의해 미세 부유물이 응집되어진 처리수는 이송관(90)내에서 지그재그로 설치된 버플판에 의해 이송 속도가 규제되어서 느린속도로 이송되어지게 된다.The treated water in which fine suspended solids are agglomerated by the polymer coagulant is controlled by a baffle plate provided in a zigzag pattern in the transfer pipe 90 so that the treated water is transferred at a slow speed.

상기 이송관(90)을 따라 이송하는 처리수는 경사판을 갖는 침전조로 유입되어지게 되는 것이다.The treated water transferred along the transfer pipe 90 is introduced into the settling tank having the inclined plate.

상기 이송관(90)을 통해 처리수가 유입되어지는 침전조에는 전술한 약제통(60)(70)(80)으로부터 약품들이 제차 투입되어지게 된다. In the settling tank into which the treated water is introduced through the transfer pipe 90, the chemicals are injected from the aforementioned medicine containers 60, 70, and 80.

상기 침전조에 유입된 처리수는 경사판에 의해 저류하거나 저유속으로 흐르면서 현탁수내의 잔여 부유물의 응집이 활성화되어지게 되고, 응집이 활성화되어 비중이 커진 부유물이 자체 비중에 의해 침전조의 아래로 침강되어서 분리되어지게 된다.The treated water introduced into the settling tank is retained by the inclined plate or flows at a low flow rate so that the flocculation of the remaining suspended matter in the suspended water is activated. Will be.

부유물이 침강되어 정화되어진 맑은 물은 여과조(40)에서 최종적으로 처리되어진 후, 방류조(50)를 거쳐 방류되어지게 되는 것이다.The clear water, which is suspended and purified, is suspended and then discharged through the discharge tank 50 after being finally treated in the filtration tank 40.

한편, 침강 분리되어진 상기 침전조 하부에 침강되어 쌓인 부유물은 부유물배출관을 통해 건조대(도면에 도시하지 않았음)로 이송되어 건조되어진 후 처리되 어지게 된다.On the other hand, the sediment is sedimented sediment is separated from the sedimentation tank sediment accumulated in the suspended solids are transferred to the drying table (not shown) through the discharge pipe is dried and then processed.

이상에서 설명한 바와 같이 터널공사 현장에서 발생한 현탁액을 포함하는 처리수를 정화처리 하는 폐수설비에서는 처리수를 최종적으로 정화처리하는 침전조의 기능에 따라 정화효율이 달라질 수 있다.As described above, the purification efficiency may vary depending on the function of the sedimentation tank which finally purifies the treated water in the wastewater facility for treating the treated water including the suspension generated at the tunnel construction site.

현재 폐수설비에서 사용되어지는 침전조(200)는 도2에 도시된 바와 같이 제1처리조(210)와 제2처리조(220)로 형성되어 있다.The sedimentation tank 200 currently used in the wastewater facility is formed of a first treatment tank 210 and a second treatment tank 220 as shown in FIG.

상기의 침전조(200)는 제2처리조(220)의 내부에 제1처리조(210)가 설치되어 있는 것이다.The precipitation tank 200 is the first treatment tank 210 is installed in the second treatment tank 220.

상기 제2처리조(220)는 침전부(221)에 아래 방향으로 경사를 이루는 경사판(222)이 등간격을 이루며 형성되어 있다.The second treatment tank 220 is formed with an inclined plate 222 which is inclined downward in the sedimentation unit 221 at equal intervals.

상기 경사판(222)은 제2처리조(220)의 내벽을 따라 동심원을 그리는 납작한 판(222a)이 아래로 경사를 이루며 형성되어 있고, 상기 제2처리조(220)의 중앙으로 설치된 제1처리조(210)의 외주면을 따라 동심원을 그리는 납작한 판(222b)이 아래로 경사를 이루며 상기의 판(222a)과 마주하도록 형성되어 있다.The inclined plate 222 is formed with a flat plate 222a drawing a concentric circle along the inner wall of the second treatment tank 220 inclined downward, and is provided with a first treatment installed at the center of the second treatment tank 220. A flat plate 222b drawing a concentric circle along the outer circumferential surface of the tank 210 is formed to be inclined downward to face the plate 222a.

상기 경사판(222)은 처리수가 상부로 부양하여 여과조(40)로 배출될때 처리수로부터 분리되어진 미세 부유물이 분양되는 것을 차단하는 역할을 하게 된다.The inclined plate 222 serves to block the fine suspended matter separated from the treated water when the treated water is floated upward and discharged into the filtration tank 40.

상기 제1처리조(210)는 중화/반응조(20)에서 황산과 반응하여 세균성 유해물질이 살균되고 황산반토와 반응하여 처리수에 포함되어 있는 부유물의 응집이 활성화되어지는 처리수가 유입되어지는 관체(211)가 설치되어 있고, 상기 관체(211)의 내부에는 처리수 이동통로(213)를 구비한 경사판(212)이 등간격을 이루며 다수 형 성되어 있되, 상기 경사판(212)의 사이사이에는 처리수의 흐름에 변화가 일어날 수 있게 하는 평판(214)들이 설치되어 있는 것이다.The first treatment tank 210 reacts with sulfuric acid in the neutralization / reaction tank 20 to sterilize bacterial harmful substances and react with alumina sulfate to allow the inflow of treated water to activate the flocculation of suspended solids contained in the treated water. 211 is provided, and inside the pipe 211, a plurality of inclined plates 212 having the treatment water movement passage 213 are formed at equal intervals, and between the inclined plates 212. Plates 214 are installed to allow changes in the flow of treated water.

상기와 같이 구성된 종래의 침전조(200)는, 처리수가 저류하는 시간과 거리가 짧아 공사현장에서 발생되는 토사 등과 같은 현탁물의 유입이 많아 처리수의 탁도가 짙을 경우, 처리수에 포함된 부유물을 깨끗하게 분리해 낼 수가 없어 정화효율이 현저하게 떨어질 뿐만 아니라, 그로 인하여 처리수에 의한 하천의 2차오염을 차단 방지할 수 없는 단점을 가지고 있다.The conventional sedimentation tank 200 configured as described above has a short time and distance for storing the treated water, and when the turbidity of the treated water is high due to the inflow of suspended matter such as earth and sand generated at the construction site, the suspended solids contained in the treated water are removed. Not only can not be separated cleanly, the purification efficiency is significantly reduced, and thereby has the disadvantage that can not prevent the secondary pollution of the river by the treated water.

따라서, 종래 침전조가 접목된 폐수설비에서의 처리수 정화를 안정되게 행하기 위해서는 침전조를 복수개 설치 사용하거나, 처리용량이 증대된 침전조를 별도로 제작하여 폐수설비를 개량 시방하여야 하는 어려움을 격게된다.Therefore, in order to stably clean the treated water in the wastewater facility to which the conventional sedimentation tank is grafted, it is difficult to install and use a plurality of sedimentation tanks or to separately prepare the sedimentation tank with increased treatment capacity to improve the wastewater facility.

All.

상기 본원 발명의 침전조에 의해 처리수내의 부유물을 정화처리하는 과정을 공정별로 설명함에 있어 종래 기술과 동일한 기술에 대해서는 동일 부호로 표기하기로 하고 침전조(100)의 전처리 공정에서 처리수를 정화 처리하는 과정은 전기에서 설명한 바 있어 본원 발명에서는 생략하기로 한다.In describing the process of purifying the suspended matter in the treated water by the sedimentation tank of the present invention for each process, the same technique as in the prior art will be denoted by the same reference numeral and the purification of the treated water in the pretreatment process of the sedimentation tank 100. Since the process has been described in the foregoing, it will be omitted in the present invention.

먼저, 침전조(100)를 구성하고 있는 제1처리조(110)의 침전부(111)에 약제통(60)의 황산과 약제통(70)의 황산반토가 공급되어 상기 처리수내에 포함되어 있는 세균성 유해물질이 살균됨과 동시에 부유물이 응집되어진 처리수가 중화/반응조(20)로부터 공급되어진다.First, sulfuric acid of the medicine container 60 and alumina sulfate of the medicine container 70 are supplied to the settling portion 111 of the first treatment tank 110 constituting the precipitation tank 100 and are contained in the treated water. At the same time as the bacterial harmful substances are sterilized, the treated water in which the suspended solids are aggregated is supplied from the neutralization / reaction tank 20.

상기와 같이 제1처리조(110)의 침전부(111)에 유입된 처리수는 스크류형 경사판(115)에 의해 저류하거나 저유속으로 흐르면서 약제통(80)으로부터 공급되어지는 고분자응집제에 의해 작은 입자의 부유물까지도 응집되어지게 된다.As described above, the treated water introduced into the sedimentation unit 111 of the first treatment tank 110 is stored by the screw-type inclined plate 115 or flows at a low flow rate. Even suspended matter is agglomerated.

상기와 같이 스크류형의 경사판(115)을 따라 저류하거나 저유속으로 흐르는처리수는 침강하는 거리가 길어 지고, 반응/응집 되는 시간이 늘어나 부유물의 응집효율이 높아지게 된다.As described above, the treated water stored along the screw-shaped inclined plate 115 or flowing at a low flow rate increases the settling distance, and the reaction / aggregation time increases, thereby increasing the flocculation efficiency of the suspended matter.

상기와 같이 스크류형 경사판(115)을 따라 저류하거나 저유속으로 흐르는 처리수는 계단형으로 절곡형성된 절곡부(115a)부위를 지날때 슬롯홀(115b)을 넘나드는 처리수에 의해 와류가 발생하게 되고, 상기 와류로 인하여 침전부(111) 내의 처리수가 교반되어지게 된다.As described above, the treated water that is stored along the screw-type inclined plate 115 or flows at a low flow rate causes vortex to be generated by the treated water passing through the slot hole 115b when passing through the bent portion 115a formed in a stepped manner. As a result, the treated water in the precipitation unit 111 is stirred due to the vortex.

상기와 같이 처리수가 교반되어지면, 약제통(80)으로부터 공급되어진 고분자응집제가 처리수내의 부유물과 골고루 섞여 응집이 활성화되어 진다.When the treated water is stirred as described above, the polymer coagulant supplied from the medicine container 80 is evenly mixed with the suspended matter in the treated water to activate the aggregation.

상기와 같와 고분자응집제에 의해 부유물의 응집이 활성화되어지므로써, 작은 입자의 부유물의 분리가 가능하게 된다.As described above, the flocculation of the suspended solids is activated by the polymer coagulant, thereby allowing the separation of the suspended solids.

상기 침전부(111)에서 응집되어 비중이 커진 부유물(슬러지)은 자체 비중에 의해 하부의 농축부(112)에 침강되어지게 되고, 작은 입자의 부유물까지 분리되어 맑은 상태로 정화된 처리수가 제2처리조(120)의 관체(121)로 유입되어 진다.The suspended solids (sludge) which is agglomerated in the sedimentation unit 111 and becomes larger in specific gravity is settled in the lower concentration part 112 by its specific gravity, and the treated water separated into small particles of suspended solids and purified in a clear state is second. It is introduced into the tube body 121 of the treatment tank 120.

상기 제2처리조(120)의 관체(121)로 처리수(현탁수)가 유입될때 미세 부유물 일부도 함께 이동되어진다.When the treated water (suspended water) flows into the tubular body 121 of the second treatment tank 120, some of the fine suspended matter is also moved.

상기와 같이 침전부(111)로부터 관체(121) 내부로 부양 이동되어지는 처리수는 상기 관체(121)의 내측에서 상광하협형을 이루는 깔대기 형상의 부유물차단판(122)에 구비된 처리수이송로(123)를 따라 상부로 부양하게 되고, 상기 처리수로부터 분리 응집된 부유물은 상기의 부유물차단판(122)에 부딛쳐 제1처리조(110)의 농 축부(112)로 침강되어지게 된다.As described above, the treated water that is floated and moved from the settling unit 111 into the tubular body 121 is transferred to the treated water provided in the funnel-shaped float blocking plate 122 that forms a light beam bottom side inside the tubular body 121. Floating to the upper portion along the furnace 123, and the flocculate separated and agglomerated from the treated water is settled to the concentrated portion 112 of the first treatment tank 110 against the float blocking plate 122. .

한편, 부유물차단판(122)에 의해 차단되어지지 않고 처리수와 함께 부유물차단판(122)의 처리수이송로(123)를 통과한 미세 부유물은 미세부유물부양차단판(124)에 의해 제차 차단되어 침강하게 되는 것이다.On the other hand, the fine suspended matter that has not been blocked by the float blocking plate 122 and has passed through the treated water transport path 123 of the float blocking plate 122 together with the treated water is blocked by the fine flotation flotation blocking plate 124. It will settle.

상기에서와 같이 처리수에 잔존하는 미세 부유물을 분리 응집시키는 관체(121)에는 약제통(60)(70)(80)에서 각각의 황산, 황산반토, 고분자응집제가 투입되어 진다.As described above, sulfuric acid, alumina sulfate, and polymer coagulant are introduced into the tubular body 121 to separate and aggregate the fine suspended matter remaining in the treated water.

상기와 같이 제2처리조(120)의 관체(121)에 약품이 투여되어 짐으로써, 전처리 공정에서 미처 처리되어지지 못한 아주작은 미세 부유물의 분리 및 응집 그리고 침강이 완벽하게 이루어지게 되는 것이다.As the drug is administered to the tubular body 121 of the second treatment tank 120 as described above, the separation and flocculation and sedimentation of very small fine suspended solids that have not been processed in the pretreatment process are perfectly performed.

상기의 제2처리조(120)의 관체(121)를 지나면서 부유물이 완전하게 처리되어진 맑은 물은 배출관(125)을 통해 여과조(40)로 배출된다.Passing through the tubular body 121 of the second treatment tank 120, the clear water is completely treated is discharged to the filtration tank 40 through the discharge pipe (125).

여과조(40)로 유입된 맑은 물은 여과조(40)에서 최종 여과 과정을 거쳐 방류조(50)를 거쳐 방류되어지게 되고, 침강 분리되어진 상기 제1처리조(110)의 침전부(111) 하부에 형성된 농축부(112)에 쌓인 부유물은 부유물배출관(114)을 통해 건조대(도면에 도시하지 않았음)로 이송되어 건조되어진 후 처리되어지게 된다.Clear water introduced into the filtration tank 40 is discharged through the discharge tank 50 through the final filtration process in the filtration tank 40, the lower portion of the sedimentation part 111 of the first treatment tank 110 is sedimentation separated The suspended matter accumulated in the condensation unit 112 is transferred to a drying table (not shown in the drawing) through the suspended matter discharge pipe 114, and then dried and processed.

이상에서 상술한 바와 같은 본발명은, 터널공사 현장에서 발생한 처리수를 정화 처리하는 폐수설비중 처리수를 최종적으로 정화 처리하는 침전조(100)의 제1처리조(110)에 형성되는 경사판(115)을 스크류형으로 개선한 것이어서 처리수가 침 전부(111)에서 회전되어지면서 저류하거나 저유속으로 흘러 부유물의 중화/응집의활성화을 기대할 수 있을 뿐만 아니라, 처리수가 흐르는 거리가 길어 동일 체적을 갖는 종래 침전조 대비 처리수의 정화처리효율이 높아 현탁물의 농도가 짙은 처리수라도 깨끗한 정화가 가능한 장점을 가지고 있다.The present invention as described above, the inclined plate 115 formed in the first treatment tank 110 of the sedimentation tank 100 for the final purification treatment of the treated water in the wastewater facility for the purification treatment of the treated water generated at the tunnel construction site. ) Is a screw type improvement, so that the treated water is rotated in the needle 111 and flows into the reservoir or flows at a low flow rate, so that the neutralization / agglomeration of the suspended solids can be expected, and the distance in which the treated water flows is long, so that it has the same volume. The high treatment efficiency of contrast treated water has the advantage that clean water can be purified even with a high concentration of suspension.

또한, 경사판(115)에 형성된 절곡부(115a)의 수평면과 수직하는 면에 슬롯홀(115b)이 형성되어 있어 처리수가 경사판(115)을 따라 흐를때 처리수 중 일부의 처리수가 슬롯홀(115b)을 넘나들면서 와류를 일으켜 처리수내의 부유물이 화학약품과 골고루 섞여 응집이 활성화되어지는 장점을 가지고 있다.In addition, the slot hole 115b is formed on a surface perpendicular to the horizontal plane of the bent portion 115a formed in the inclined plate 115, so that when the treated water flows along the inclined plate 115, a part of the treated water is processed into the slot hole 115b. It has the advantage that the flotation in the treated water is mixed evenly with chemicals to activate the coagulation.

아울러, 본원 발명은 중화/반응조로 부터 공급된 처리수가 체적이 넓은 침전부(111)를 포함하는 제1처리조에서 부유물이 분리 침강되어진 후 제2처리조를 통과하면서 잔여 미세 부유물이 처리되어지게 하는 것이어서 미세 부유물의 발생을 최소화시켰을 뿐만 아니라, 미세 부유물의 발생이 적어 짐에 따라 제2처리조의 처리부하를 줄일 수 있는 이점을 가지고 있다.In addition, the present invention is to process the remaining fine suspended solids while passing through the second treatment tank after the sediment is separated and settled in the first treatment tank including the sedimentation portion 111 having a large volume of water supplied from the neutralization / reaction tank. In addition to minimizing the generation of fine suspended solids, as the generation of fine suspended solids has the advantage of reducing the processing load of the second treatment tank.
