The upper portion of the slurry reservoir is provided with a stirring motor, and a stirring motor and an impeller are connected therein to stir the tainted water stored in the slurry reservoir by the stirring motor. The size of the slurry reservoir is adjusted according to the amount of the excavated soil, and the structure and the method of use may be a conventional slurry storage tank that is generally used in an industrial site.

그리고 상기 슬러리 저장조에는 저장된 오탁수를 응집제와 혼합하는 인라인믹서가 연결 설치되는데, 오탁수는 인라인믹서를 통과하면서 응집제와 혼합되는 것으로, 상기 인라인믹서와 응집제 또한 산업현장에서 일반적으로 사용되는 관용의 것을 사용하며 응집제 투입 방법은 여러 가지 방식이 가능하나 일례로 노즐을 이용한 관용의 분사방식으로 설치하면 된다.
In addition, the slurry storage tank is connected to the in-line mixer for mixing the stored sewage water with the flocculant, the waste water is mixed with the flocculant while passing through the inline mixer, the inline mixer and flocculant is also commonly used in industrial sites The flocculant injection method can be used in various ways, but for example, it can be installed by the conventional injection method using the nozzle.

또한, 상기 인라인믹서를 통과하면서 응집제와 혼합된 오탁수는 미세한 토사가 응집제와 혼합되어 응집된 큰 덩어리 토사인 플록이 형성되면서 상기 슬러리 저장조와 인접하여 지상에 설치된 고속 침전조로 이송되며, 이 때 상기 고속 침전조의 상부에는 청등수가 형성되고, 하부에는 오탁수에 미세한 토사가 응집제와 혼합되어 응집된 큰 덩어리인 플록이 형성된 상태로 있게 되는데, 상기 고속 침전조 상부에 형성된 청등수는 고속 침전조에 인접하여 설치된 청등수 저장조로 이송되어 저장되며, 상기 고속 침전조의 하부에 침전된 상태인 플록은 상기 고속 침전조와 인접하여 지상에 설치된 압력여과기로 이송되어 플록에서 수분을 제거한 후 남는 토사는 고형화하여 탈수케익 상태로 외부로 반출하고, 탈수된 여과수는 상기 슬러지 저장조로 이송되어 저장된 후 고속 침전조로 재투입되어 재차 침전하는 과정을 반복하게 된다.
In addition, the effluent water mixed with the coagulant while passing through the inline mixer is transferred to a high-speed sedimentation tank installed on the ground adjacent to the slurry storage tank while forming flocs of flocculent large agglomerated soils mixed with fine coarse sand. In the upper part of the high-speed sedimentation tank, the blue water is formed, and in the lower part, the fine soil is mixed with the coagulant and the floc is formed in the form of floc, which is formed in the upper part of the high-speed sedimentation tank. The floc, which is transferred to and stored in the blue water storage tank, is settled in the lower part of the high-speed sedimentation tank, and is transferred to a pressure filter installed on the ground adjacent to the high-speed sedimentation tank to remove moisture from the floc. Exported to the outside, the dewatered filtrate is sent to the sludge reservoir. After stored is re-fed to the high-speed settling tank will again repeat the process of precipitation.

For example, referring to the high-speed sedimentation tank and the pressure filter for the main pipe which are generally used in the art, the wastewater introduced into the upper portion of the high-speed sedimentation tank through the inlet pipe is a plurality of slope plates. As it passes, the floc is formed and moved to the lower part of the high-speed sedimentation tank, and the blue water separated from the floc flows into the blue water storage tank and is stored therein. Pressure filter is also known as filter press, and several to tens of filter plates and filter frames are installed horizontally and alternately in parallel, and a filter cloth is sandwiched between them and fastened tightly. When the liquid to be filtered is pressed into the filter frame, the filtrate flows through the manure cloth to the manure plate, and the debris accumulates in the manure cloth. The power to clamp the filter plate of the pressure filter is usually used hydraulically. The conveyor belt is installed under the pressure filter to take out the solidified floc. Detailed technical descriptions of the conventional components are omitted.
