본 발명은 준설선을 이용한 슬러지 처리공법에 관한 것으로서, 보다 상세하게는 준설선이나 펌핑 가능한 장치를 이용하여 하천이나 저수지등의 바닥에 퇴적된 오염 퇴적물을 흡입하고 이를 분리 정화시킴으로써 자갈이나 모래를 분리하여 재활용의 용도로 사용 가능하고 오탁수를 정수하여 하천이나 저수지등에 재 투입하여 오염을 방지시킬 수 있는 슬러지 처리공법에 관한 것이다.The present invention relates to a sludge treatment method using a dredger, and more specifically, by using a dredger or a pumpable device to suck the contaminated sediments deposited on the bottom of rivers or reservoirs, and to separate and clean the gravel or sand to recycle The present invention relates to a sludge treatment method that can be used for the purpose of water purification, and can be used to purify polluted water and re-inject it into a river or reservoir to prevent contamination.

일반적으로, 현대사회에서는 도시의 팽창과 산업 발달로 인하여 가정이나 공장등지에서 오폐수가가 급격하게 증가하고 있으며, 이에따라 생활하수 및 오폐수가 하천이나 저수지 기타 바닷가등으로 유입되어 수질 오염을 촉발하고 있는 실정이다.In general, in modern society, wastewater is rapidly increasing in homes and factories due to urban expansion and industrial development.As a result, household sewage and wastewater flow into rivers, reservoirs and other beaches to trigger water pollution. to be.

또한 이러한 오폐수가 유입되는 과정에서 생활쓰레기나 흙 기타 이물질이 다량으로 혼합된 상태로 유입되는 것이기 때문에 어느 시간이 경과하게 되면 퇴적물 형태로 존재하게 된다.In addition, since the wastewater is introduced in a state where a large amount of garbage, soil and other foreign substances are mixed in the process of inflow, it is present in the form of sediment after a certain time.

이와같이 퇴적물 형태로 존재하게 되면 시간이 경과함에 따라 물의 오염이 좀더 심하게 되고, 악취가 발생되며, 하천의 원활한 흐름을 저해하여 홍수시 침수해를 가중시키는 요인이 되고 있는 바, 따라서 오염 퇴적물을 근본적으로 제거해야 할 필요가 있다.As such, the presence of sediment in the form of water becomes more severe as time passes, odors are generated, and the smooth flow of rivers is impeded, causing flooding damage during flooding. It needs to be removed.

본 발명의 상술한 목적과 여러 가지 장점은 이 기술 분야에 숙련된 사람들에 의해, 첨부된 도면을 참조하여 후술되는 본 발명의 바람직한 실시 예로부터 더욱 명확하게 될 것이다.The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

이하 본 발명에 따른 준설선을 이용한 슬러지 처리공법의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of the sludge treatment method using a dredger according to the present invention will be described in detail with reference to the accompanying drawings.

도 1 및 도 2는 본 발명에 따른 준설선을 이용한 슬러지 처리공법을 나타낸 공정도이다.1 and 2 is a process chart showing a sludge treatment method using a dredger according to the present invention.

이에 나타내 보인 바와 같이 본 발명에 다른 준설선을 이용한 슬러지 처리공법은, 먼저, 굴삭기(10)를 통해 호퍼(hopper;20)내로 준설토를 유입한다.As shown in the sludge treatment method using a dredger according to the present invention, first, dredged soil is introduced into a hopper 20 through an excavator 10.

그리고 호퍼(20)상에 설치된 고압펌프(30)를 통해 덩어리 상태의 준설토를 분쇄시키는 공정을 수행한다.Then, a process of pulverizing the dredged soil in a lump state is performed through the high pressure pump 30 installed on the hopper 20.

다음으로, 분쇄된 준설토를 라인(P)을 통해 제1차 싸이크론(40)으로 이송하여 교란시키는 작업을 수행한다.Next, the ground dredged soil is transferred to the primary cyclone 40 through the line P to perform a disturbing operation.

이때 분쇄된 준설토를 제1차 싸이크론(40)으로 이송시키는 작업은 임펠러 방식을 취하는 것이 아니라 기압 펌프(MP)를 통해 이루어지도록 함이 바람직한 바, 이는 임펠러 방식으로 이송시킬 경우 임펠러상에 준설토상에 혼합될 수 있는 그물이나 기타 로프나 큰 덩어리등이 끼게되어 작동이 원활하게 이루어지지 않기 때문에 이를 미연에 방지하기 위함이다.At this time, the operation of transferring the crushed dredged soil to the first cyclone (40) is preferably to be carried out through the air pressure pump (MP), not to take the impeller method, which is transferred to the dredged soil on the impeller This is to prevent this because the net or other rope or large lumps that can be mixed are caught and the operation is not performed smoothly.

상술한 제1차 싸이크론(40)을 통해 교란된 준설토는 이송라인(P)을 통해 샌드 스크린(50)으로 이동 통과시킨다.The dredged soil disturbed through the first cyclone 40 described above moves through the transfer line P to the sand screen 50.

이를 통해서는 오니, 슬러지, 골재등의 입자가 큰것과 작은 입자로 분리된다.Through this, particles such as sludge, sludge and aggregate are separated into large and small particles.

이때 입자가 큰것은 벨트 콘베이어(B)를 사토장으로 배출함으로써 재활용 가능한 것을 분리할 수 있게된다.At this time, the larger particles can be separated by recycling the belt conveyor (B) to the soil.

또한 작은 입자 상태의 준설토 즉, 슬러지는 역시 이송라인(P)을 통해 제2차 싸이크론(60)로 이동되어 교란공정이 이루어진다.In addition, the dredged soil, that is, the sludge of the small particle state is also moved to the secondary cyclone 60 through the transfer line (P) is made a disturbing process.

한편, 상술한 제1차 싸이크론(40)으로부터 샌드 스크린(50)으로 준설토를 이동시킴에 있어서는, 표면적이 넓은 슈트(41)를 통해 이루어지도록 함이 이송과정에서 유출될 우려를 미연에 방지할 수 있어 바람직할 것이다.On the other hand, in moving the dredged soil from the first cyclone 40 to the sand screen 50, it is possible to prevent the risk of spillage during the transfer process to be made through the chute 41 having a large surface area. Would be desirable.

상술한 제2차 싸이크론(60)에 의해 교란된 작은 입자 상태의 작은 입자 상태의 준설토는 다시 샌드 스크린(50)을 통과하게 되고, 여기에서 걸려진 미세입자가 혼합된 오탁수 즉, 슬러지는 배관라인(P)을 통해 응집탱크(70)로 이동된다.The dredged soil of the small particle state of the small particle state disturbed by the secondary cyclone 60 is passed through the sand screen 50 again, and the filthy water mixed with the fine particles caught therein, that is, the sludge pipe It is moved to the coagulation tank 70 through the line (P).

이때 오탁수 즉, 슬러지가 응집탱크(70)로 이동되는 과정에서 배관라인(P)상에 위치된 약물 투입기(80)의 정량 공급 펌프(81)에 의해 슬러지상에 응집을 촉진시키는 약물이 투입된채 교반되면서 응집탱크(70)로 이동된다.At this time, filthy water, that is, a drug that promotes coagulation on the sludge is introduced by the metering feed pump 81 of the drug injector 80 located on the pipe line P while the sludge is moved to the coagulation tank 70. It is moved to the coagulation tank 70 while stirring.

이와같이 응집탱크(70)로 이동된 응집 약물이 투입된 슬러지는 고속 교반기(90)와 저속 교반기(100)를 순차적으로 통과하게 되며, 이 과정에서 안정화되어진다.As such, the sludge into which the coagulant drug moved to the coagulation tank 70 is sequentially passed through the high speed stirrer 90 and the low speed stirrer 100, and is stabilized in this process.

이 안정화된 슬러지를 탈수장치(110)에 유입하게 되면, 탈수장치(110) 내에서 상,하로 분리된다.When the stabilized sludge is introduced into the dewatering device 110, the dewatered sludge is separated up and down in the dewatering device 110.

즉, 상부측은 물이 하부측은 응집된 슬러지로 분리되는 것이다.That is, the upper side is separated into water and the lower side is agglomerated sludge.

여기에서 상부측의 물은 필터(120)를 통해 맑은 물 상태로 배출시키게 되면 오염되지 않은 물의 배출이 가능하게 된다.Here, the water of the upper side is discharged to the clear water state through the filter 120, it is possible to discharge the uncontaminated water.

또한 하부의 슬러지는 정량 공급 밸브(V)를 통해 스크린 콘베이어(130)로 이동시키게 되는 바, 이송 과정에서 배출되는 물은 역시 필터(120)를 통과하면서 하 부의 호퍼(20‘)로 배출되며, 탈수된 슬러지는 차량에 적재되어 매립지등으로 배출되는 것이다.In addition, the lower sludge is moved to the screen conveyor 130 through the metering supply valve (V), the water discharged during the transfer process is also discharged to the lower hopper 20 'while passing through the filter 120, Dehydrated sludge is loaded into vehicles and discharged to landfills.

이와같은 공정을 통해 신속한 준설 작업을 행할 수 있게되며, 골재나 오니, 기타 큰 이물질과 슬러지의 분리가 손쉽게 이루어지고, 맑은 물을 분리 배출시킬 수 있게되며, 오염된 슬러지를 건조 상태로 분리 배출시킬 수 있게됨으로 2차 오염의 문제점을 해결할 수 있게된다.Through this process, dredging can be carried out quickly, separation of aggregates, sludge, and other large foreign substances and sludge can be easily performed, clear water can be separated and discharged, and contaminated sludge can be separated and discharged in a dry state. This can solve the problem of secondary pollution.

이상의 설명에서 본 발명은 특정의 실시 예와 관련하여 도시 및 설명하였지만, 특허청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화가 가능하다는 것을 당 업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described in connection with specific embodiments thereof, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who owns it can easily find out.
