During the process that the sliding bar 52 moves along the inclined surface of the wedge-shaped frame 54, the sliding bar 52 pushes the sliding triangle block 48 to move, the return spring 49 is compressed, then the sliding bar 52 contacts with the other side of the sliding triangle block 48, the sliding triangle block 48 is reset under the reset action of the return spring 49, then the electric push rod 21 is controlled to contract manually, so that the second fixing frame 22 and the upper device thereof move downwards, the sliding strip 52 drives the sliding triangle block 48 and the upper device thereof to move downwards, wherein the mixed powder of the xanthomonas campestris and the D-glucose on the fermentation filter screen 43 can produce the L-ascorbic acid through fermentation, the electric push rod 21 is manually controlled to continue to move downwards, so that one of the fermentation filter screens 43 attached with the L-ascorbic acid is in full contact with the heavy metal wastewater inside the first fixing frame 1, and then the heavy metal wastewater inside the first fixing frame 1 can be purified.

During the downward movement of the sliding bar 52 and the device thereon, the sliding bar 52 is separated from the third fixing plate 57, the third fixing plate 57 is then restored by the restoring action of the fourth restoring spring 58, and the wedge block 62 is restored by the restoring action of the sixth restoring spring 65, so that the mixed powder of the xanthomonas campestris and the D-glucose in the second fixing frame 61 can be sprayed onto one of the fermentation screens 43.

And then manually controlling the electric push rod 21 to extend to reset the second fixing frame 22 and the devices thereon, resetting the sliding strip 52 along the third fixing plate 57, separating the sliding strip 52 from the sliding triangular block 48, driving one of the fermentation filter screens 43 and the devices thereon to reset by one of the magnetic blocks 45, and finally manually controlling the electric push rod 21 to stop operating, wherein the operation is repeated to enable the equipment to secondarily treat heavy metal wastewater.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
