According to this device, the necessary equipment for the muddy water treatment device is attached in one block to the two upper and lower frames that can be divided, and it is possible to provide a muddy water treatment device that is transportable and does not require a large installation area. Furthermore, since it is only necessary to connect the devices on both frames on-site, there is an advantage that the installation work can be completed in a short time. However, the two blocks must be transported separately, and installation work such as connections between the devices must be carried out on site, which has the disadvantage that it cannot adequately handle the construction work of magnolias, which requires frequent relocation. Furthermore, while the muddy water treatment equipment is in operation, it is necessary to constantly supply water into the thickener, making the equipment and maintenance inspection troublesome. In order to eliminate the need to perform on-site connection work between the devices of the two blocks, it is conceivable to arrange all the devices on the same frame.

However, there is a limit to the area that can be loaded with transport vehicle steel.
If all the equipment of the two blocks were arranged on the same frame, it would be impossible to fit them within a transportable area. Furthermore, there are also problems in the treatment of furnace liquid discharged from the dehydrator. The present invention improves the above-mentioned prior invention, and provides a compact, portable solid-liquid separation device that does not require installation work by rationally arranging all equipment on a frame with a transportable area. , which circulates treated water and eliminates the need for water supply during work. In order to achieve the above object, the present invention provides a muddy water introduction tank and a primary flocculation reaction tank integrally equipped with a triangular weir in the upper part of the thickener, and attaches the muddy water introduction tank and the primary flocculation reaction tank to the frame. In addition, a second flocculant dissolving tank is provided above the second flocculant storage tank to eliminate the need for installation area on the frame of the second flocculant dissolving tank, and a furnace liquid receiving tank is installed at the bottom of the dehydrator. At the same time, the furnace liquid in the furnace liquid receiving tank is returned to the primary flocculation reaction tank via a pump and piping, and the thickener top water connected to the primary flocculation reaction tank is used as a first and second flocculant. It is characterized in that it is circulated and used as dissolving water in the dissolving tank and washing water for the furnace cloth in the dehydrator, thereby eliminating the need for water supply during work.
