Description

Be applied to sewage collection system of aircraft Technical Field The utility model relates to the technical field of sample collection, in particular to a sewage collection device applied to an aircraft. Background Passenger aircraft produce a large amount of sewage every day, including toilet wastewater, drinking water residues, etc., and may have harmful substances such as bacteria, viruses, etc. The related departments of epidemic situation joint defense joint control can acquire the contents of bacteria, viruses and the like in the sewage in time by monitoring the sewage on a single passenger aircraft, so that the epidemic situation development situation is more accurately researched and judged, and the epidemic situation monitoring and treatment are enhanced. At present, a water tank on a passenger aircraft is discharged into a sewage vehicle through a pipeline, the water tank is flushed after the discharge is completed, and residual water in the pipeline is sampled finally, namely, the collected liquid is the liquid after flushing and dilution, so that the concentration of harmful substances in the sampled liquid is low, the result is inaccurate, and the detection failure and omission phenomenon possibly occurs.
