본 발명은 유체의 흐름에 따라 생성되는 슬럿지나 정수조 및 폐수처리과정등에서 생성된 각종 슬럿지에 함유된 수분을 탈수시키고 탈수처리된 슬럿지만을 폐기처리하거나 이를 재활용할 수 있도록 한 원통형 슬럿지 탈수 시스템에 관한 것이다.The present invention relates to a cylindrical sludge dewatering system for dehydrating water contained in various sludges generated in a sludge or water treatment tank and wastewater treatment process according to the flow of a fluid, and disposing or recycling only the dehydrated slots. will be.
일반적으로 유체가 흐르는 유체 이동시스템에서는 상기 유체에 함유된 각종 오니와 불순물등이 침전되어 슬럿지가 생성되고 있으며, 정수조와 폐수처리장치 및 화학,생물학적 처리과정과 식품제조과정등에서도 여러 가지 성분이 함유된 슬럿지가 생성되고 있다.In general, the fluid movement system in which the fluid flows generates sludge by depositing various sludges and impurities in the fluid, and also contains various components in water purification tanks, wastewater treatment devices, chemical and biological treatment processes, and food manufacturing processes. Sludge is being created.
상기와 같이 생성되는 슬럿지에는 많은 수분이 함유되고 있기 때문에 이 슬럿지를 처리하고져 할 때는 상기 슬럿지에 함유된 수분을 제거해야만 그 처리가 용이하게 되고 처리될 슬럿지의 량을 줄일 수 있게 된다.Since the sludge produced as described above contains a lot of water, when the sludge is to be treated, the water contained in the sludge should be removed to facilitate the treatment and to reduce the amount of sludge to be treated.
한편, 상기와 같이 생성된 슬럿지에서 수분을 제거하기 위하여 많은 노력을 기울이고 있으나, 그 대다수는 상기 슬럿지를 강제적으로 가압하여 수분을 제거하는 가압방식의 탈수장치로 되어 있고 또, 원심분리방식에 의한 탈수장치가 개발되어 오고 있었다.On the other hand, although a lot of efforts have been made to remove the water from the sludge produced as described above, the majority of them are a dehydration device of the pressurized method to forcibly pressurize the sludge to remove the water, and dehydration by centrifugal separation method The device has been developed.
그러나, 상기와 같은 탈수장치들은 그 탈수효율이 대략 50-60% 수준에 머물러 슬럿지에서 수분제거를 충분히 하지 못하고 있었으며, 특히 상기 슬럿지에서 수분을 탈수시킬 때 상기 수분과 함께 상당량의 슬럿지가 탈리되기 때문에 상기 탈수된 수분을 그대로 처리할 경우 상기 수분에 함유된 슬럿지의 오염성분이 환경을 해치게 될 염려가 있으며 상기 탈수된 수분에서 유해성분을 탈취하기 위한 노력을 기울여야 하는 등의 문제점이 있었다.However, the dehydration apparatus as described above did not sufficiently remove the water from the sludge due to its dehydration efficiency remaining at approximately 50-60% level, especially since a considerable amount of sludge is desorbed together with the water when the water is dewatered from the sludge. If the dehydrated water is treated as it is, there is a concern that the contaminants of the sludge contained in the water may damage the environment, and there is a problem that efforts should be made to deodorize harmful ingredients from the dehydrated water.
본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 유체의 흐름에 따라 생성되는 슬럿지나 정수조 및 폐수처리과정등에서 생성된 각종 슬럿지에 함유된 수분을, 슬럿지의 유입공정과 가압/탈수공정 및 슬럿지 분리/털어내기공정에 의하여 제거시키고 상기 수분제거에 따라 탈수처리된 슬럿지만을 폐기처리하거나 이를 재활용할 수 있도록 한 원통형 슬럿지 탈수 시스템을 제공하려는 것인바, 이를 이하에서 바람직한 실시예와 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, and the water contained in the sludge produced by the flow of the fluid, the various sludge produced in the water treatment tank and the wastewater treatment process, the sludge inflow process and pressurization / It is to provide a cylindrical sludge dewatering system that can be removed by the dehydration process and the sludge separation / stripping process and the wastewater treated by the dewatering process can be disposed of or recycled.

The agitator 7 installed in the reservoir 6 is operated so that the sludge 12 and the coagulant are mixed well while being stirred, and the sludge 12 supplied to the sludge concentrated storage tank 6 is in a state in which it can be supplied.
상기한 상태에서 슬럿지 공급펌프(8)를 가동시키게 되면, 상기 슬럿지 농축저장조(6)에 공급된 응집제가 함유된 슬럿지(12)는 상기 원통형 탈수 필터프레스(1)로 공급되고 이 공급된 슬럿지(12)는 도 2에서와 같이 여과망(9)에 의하여 일차적으로 여과된다.When the sludge feed pump 8 is operated in the above state, the sludge 12 containing the coagulant supplied to the sludge thickening reservoir 6 is supplied to the cylindrical dewatering filter press 1 and the sludge supplied ( 12 is primarily filtered by the filtering network 9 as in FIG.
상기한 상태에서 상기 가압수 탱크(2)의 가압수(13)를 가압펌프(3)에 의하여 원통형 탈수 필터프레스(1)로 공급하게 되면, 도 3에서와 같이 공급되는 가압수(13)가 다이아프램(10)을 가압하게 되고 이 가압되는 다이아프램(10)이 상기 여과망(9)을 가압하면서 여과망(9)내의 슬럿지(12)가압하게 되며, 이때 상기 슬럿지(12)에 함유된 수분이 탈수되어 1차 탈수가 이루어지고 이 탈수과정이 끝나면, 상기 가압펌프(3)에 의하여 공급되는 가압수(13)가 도 4에서와 같이 여과망(9)의 여러곳에 설치된 슬럿지 분리용 다이아프램(11)를 가압시키게 되며 이 가압작용에 의하여 상기 원통형 탈수 필터프레스(1)내의 여과망(9)에 탈수된 상태로 있는 슬럿지(12)를 분리하고 털어내어 2차 탈수작용이 이루어지면서 상기 슬럿지(12)를 원통형 탈수 필터프레스(1)에서 용이하게 배출할 수 있도록 되는 것이다.When the pressurized water 13 of the pressurized water tank 2 is supplied to the cylindrical dewatering filter press 1 by the pressurized pump 3 in the above state, pressurized water 13 supplied as shown in FIG. The diaphragm 10 is pressurized and the pressurized diaphragm 10 pressurizes the filter net 9 to pressurize the sludge 12 in the filter net 9, and at this time, the water contained in the sludge 12 When the dehydration is carried out and the primary dehydration is completed and the dehydration process is completed, the pressurized water 13 supplied by the pressure pump 3 is a sludge separation diaphragm 11 installed in several places of the filter network 9 as shown in FIG. The sludge 12 which is dehydrated in the filter network 9 in the cylindrical dewatering filter press 1 by the pressing action is separated and shaken out, and the second dewatering action is performed. Can be easily discharged from the cylindrical dewatering filter press (1). It will be so.
상기와 같은 동작을 반복적으로 행하게 되면, 상기 슬럿지 농축저장조(6)에 공급된 슬럿지(12)를 연속적으로 탈수시키면서 수분이 제거된 슬럿지를 배출할 수 있게 되며, 상기 슬럿지(12)의 탈수작업이 종료되면, 상기 원통형 탈수 필터프레스(1)에 물을 공급하여 세척하고 재사용하게 되는 것이다.When the above operation is repeatedly performed, the sludge 12, which is dehydrated, can be discharged while continuously dewatering the sludge 12 supplied to the sludge concentration storage tank 6, and the dewatering operation of the sludge 12 is performed. When finished, the cylindrical dewatering filter press (1) by supplying water to be washed and reused.
이상과 같은 본 발명은 상기와 같이 수분이 함유된 슬럿지(12)를 가압수로 가압하면서 탈수시키도록 하므로써 상기 탈수작업이 원활하게 이루어지며 상기 2차 탈수작용에 의한 탈수율이 매우 높아 함수율을 20-30%로 할 수 있게 되고 이에 따라 상기 슬럿지(12)를 종래의 30-50% 수준의 량을 줄일 수 있게 되며 상기 재활용 또는 폐기시킬 슬럿지를 크게 줄일 수 있게 된다.As described above, the dehydration operation is made smoothly by dehydrating the sludge 12 containing moisture as described above with pressurized water, and the dehydration rate due to the secondary dehydration is very high. It is possible to achieve -30%, thereby reducing the amount of sludge 12 of the conventional 30-50% level and greatly reducing the sludge to be recycled or discarded.
또, 상기 슬럿지의 탈수작업을 무인 운전 상태에서 행할 수 있고 원통형 탈수 필터프레스(1)에서 탈수작용을하여 배출하도록 하므로써 상기 유해한 성분이 함유된 슬럿지의 경우에도 작업자의 신체를 접촉시킬 필요가 없어 안전한 탈수작업이 이루어지게 되고 탈수 효율을 크게 향상시킬 수 있게 되는 점 등의 특징을 지닌 것이다.In addition, the sludge dewatering operation can be carried out in an unattended operation state, and the sludge containing the harmful components does not need to be in contact with the operator's body by allowing the cylindrical dewatering filter press 1 to be discharged by dehydration. The dewatering operation is made and features such as being able to greatly improve the dewatering efficiency.
