The invention relates to the technical field of drainage and discloses a semi-vacuum drainage system. The semi-vacuum drainage system comprises an elevator (1) and a vacuum unit (2). The elevator (1) is connected with the vacuum unit (2) through a vacuum pipe (3). The vacuum unit (2) comprises a sewage tank (21). The sewage tank (21) is connected with a vacuum pump (24) and a control cabinet (23). The vacuum pump (24) is connected with an air-liquid separator (22) and the control cabinet (23). An electric contact pressure meter (25) is arranged between the sewage tank (21) and the control cabinet (23). The sewage tank (21) is provided with a sewage pump (26). The sewage pump (26) is connected with the control cabinet (23) and a sewage discharge pipe (27). A fourth liquid lever sensor (28) is arranged in the sewage tank (21). The semi-vacuum drainage system is used for collecting sewage and waste water in a closed mode to prevent bad smell from overflowing. According to the semi-vacuum drainage system, a first overhauling opening is formed in the upper side of a sewage collection tank, a second overhauling opening is formed in the upper side of a waste water collection tank, and a third overhauling opening is formed in the upper side of a floor drain collection tank, so that the devices are easy to overhaul and maintain, and operation and maintenance staff can master the overhauling method quickly.
