The invention relates to a sludge dehydration system based on circulation brine dialysis. The sludge dehydration system comprises a plurality of novel drain boards, a sludge processing tank, a vacuum pump, and a brine tank. The novel drain boards are arranged in the sludge processing tank. Each drain board comprises a board core, which is in a grating shape and is provided with multiple channels, a dialysis membrane, and a geotechnical cloth filter membrane, wherein the dialysis membrane and the geotechnical cloth filter membrane are nested on the surface of the board core in sequence. Two ends of the channels of the board core are connected and communicated with the vacuum pump and the brine tank. A valve is arranged between the channels of the board core and the brine tank. 本发明涉及种基于循环盐液渗析的污泥脱水系统，包括若干新型排水板、污泥处理池、真空泵和盐液池；其中若干新型排水板铺设在污泥处理池内，所述新型排水板包括呈格栅状的开设有若干通道的板芯和依次嵌套在板芯表面上的透析膜和土工布滤膜，所述板芯的通道的两端分别与真空泵、盐液池连接及连通，板芯的通道与盐液池之间设置有阀门。
