[0022] as attached figure 1 to the attached Figure 5 shown:

[0023] The present invention is a water sample pretreatment and filtering device for environmental monitoring laboratory. The water pump 5 is installed on the lower right end of the suction pipe 2, and the upper left end of the suction pipe 2 is installed on the top of the filter device 6 and communicates with each other. The four corners of the filter device 6 are welded with supporting feet 4. The filter device 6 includes a filter box 65, a motor 62, an adsorption mechanism 68, a filter plate mechanism 63, and a drain pipe 66. The upper left end of the suction pipe 2 is installed on the top of the filter box 65 and communicates with each other. There is a motor 62, and the output end of the motor 62 is connected with the internal drive of the adsorption mechanism 68. The adsorption mechanism 68 is installed on the upper end of the inner side of the filter box 65. The four corners of the bottom
