A filter tube 38 is provided in the filter chamber 6 corresponding to the inlet 37, and the input port of the filter tube 38 is connected to the inlet 37. A sampler 2 (not shown in the figure) is fixedly connected to the input port of the filter tube 38, and the sampler 2 is used for secondary sampling and detection of the seawater flowing into the filter tube 38;

[0067] like Figure 7 The filter tube 38 is provided with a plurality of tubular membrane assemblies 39, which are conventional technologies and are used to filter and remove antibiotic components in seawater;

[0068] Several tubular membrane assemblies 39 are arranged linearly along the axial direction of the filter chamber 6. An electric control valve 40 is fixedly connected to the upper side of each tubular membrane assembly 39 on the filter tube 38. The upper side of each group of electric control valves 40 and the lower side of the lowest tubular membrane assembly 39 on the filter tube 38 are connected with a connecting pipe 41.
