The invention relates to an integral grey water and sewage tank for an operation vehicle. The integral grey water and sewage tank comprises a grey water tank and an airtight inner tank, wherein grey water is connected with the grey tank box through a grey water pipe; the grey water tank is connected with the inner tank through a pipeline with an electromagnetic pipeline valve; a liquid level switch is arranged on the grey water tank; the open and the close of the electromagnetic pipeline valve are controlled by the liquid level switch; the inner tank communicates with a vacuum system; sewage in a stool pot is absorbed into the inner tank of the sewage tank in a vacuumizing manner; a liquid level alarming machine and a liquid level alarming and forbidding machine are arranged on the inner tank; a blowdown valve and a gas valve are also arranged on the inner tank; the gas valve is connected with a pressure air source; the grey water enters the grey water tank through a grey water pipe under the effect of gravity, when the liquid level of the grey water in the grey water tank triggers the liquid-level switch, the liquid-level switch triggers an electromagnetic pipeline valve to be turned on; the grey water is absorbed into the inner tank of the sewage tank under the effect of vacuum, and the pipeline valve is turned off; when the liquid level in the inner tank of the sewage tank reaches to the liquid level alarming machine, the system sends an alarm; when the liquid level reaches to the liquid level alarming and forbidding machine, the system sends an alarm and enables the sewage tank to be disabled; when the requirement of the inner tank for discharging sewage is met, the sewage discharge is performed by the blowdown valve through air pressure.
