As shown in fig. 2, the first tubular silicon carbide ceramic film, the second tubular silicon carbide ceramic film, and the third tubular silicon carbide ceramic film have the same structure, specifically, the first tubular silicon carbide ceramic film is taken as an example:
the first tubular silicon carbide ceramic membrane 3 comprises a tubular shell 31, a filter screen cylinder 32 is coaxially arranged inside the tubular shell 31, the filter screen cylinder 32 is coated with a silicon carbide ceramic membrane, a liquid inlet 311 and a liquid outlet 312 are respectively arranged at two ends of the tubular shell 31, an overflow port 313 is arranged on the side wall of the tubular shell 31, a first sampling tube 314 and a second sampling tube 315 are also respectively arranged on the side wall of the tubular shell 31, one end of the first sampling tube 314 is arranged outside the tubular shell 31, the other end of the first sampling tube is arranged between the outer wall of the filter screen cylinder 32 and the inner wall of the tubular shell 31, one end of the second sampling tube 315 is arranged outside the tubular shell 31, and the other end of the second sampling tube 315 is arranged inside the filter screen cylinder 32.
