The invention provides a sewage tank and a vacuum excrement collecting system, relates to the technical field of vacuum excrement collecting systems, and aims at solving the technical problems that a liquid level sensor in the sewage tank is short in service life and inconvenient to disassemble and assemble. The sewage box comprises a sewage box body, an opening is formed in the top of the sewage box body, a window is arranged in the opening, and the window is made of wave-transparent materials; the radar liquid level sensor is arranged on the side, away from the interior of the sewage box body, of the window and used for collecting liquid level height information in the sewage box body through the window. The embodiment of the invention is used for prolonging the service life of the liquid level sensor and reducing the dismounting difficulty of the liquid level sensor.
