based on the above, after the microbial bacterial dregs and the multi-element metal ion solution are mixed in the reaction barrel 1, the mixed solution is poured into the filtering through pipe 61 by opening the electromagnetic valve on the side of the Y-shaped pipe 64 close to the filtering recovery mechanism 6, then the water solution in the mixed solution is filtered by the filtering pipes X62 and Y63 arranged at the top and the left side of the filtering through pipe 61, and the microbial filter residues are filtered to the position where the filter residues are collected at the bottom of the filtering through pipe 61, so that the mixed solution can be rapidly filtered, and the efficient filtering effect is achieved;

based on the above, after the microbial dregs sufficiently adsorb the multi-element metal ions, the microbial dregs flow into the filtering through pipe 61, and then the solution in the filtering pipe X62 and the filtering pipe Y63 is sucked through the negative pressure filtering pipe 65, so that the filtering speed of the mixed solution is accelerated;

based on the above, a plurality of recovery filter plates 612 are arranged inside the recovery support 611, the first recovery filter plate 612 near the residue output pipe of the through-filtration pipe 61 is in a state perpendicular to the flow direction of the solution in the through-filtration pipe, and filters the solution, and the subsequent recovery filter plates 612 are in a state parallel to the flow direction of the solution in the through-filtration pipe;

based on the above, when the position of the recycling filter plate 612 needs to be fixed, two sets of fixed filtering limiting rods 613 corresponding to the horizontal direction and the vertical direction are inserted into the corresponding limiting holes inside the recycling filter plate 612, so as to complete the fixing operation of the recycling filter plate 612, and meanwhile, when the first recycling filter plate 612 is attached with excessive microorganism filter residues, the inserted fixed filtering limiting rods 613 inside the recycling filter plate 612 can be drawn out, so that the first recycling filter plate 612 is turned over along with the flow of water, so that the filter residues on the first recycling filter plate 612 are scattered into the mixed solution and participate in the filtering process again, and by analogy, the filter residues attached to the previous recycling filter plate 612 can be recycled in the filtering process, the effect of reducing the loss of raw materials is achieved;

based on the above, behind the microorganism filter residue after reaction barrel 1 to input adhesion agent and drying, mix it through mixing arrangement, open the solenoid valve that Y venturi tube 64 is close to pelletization dust recovery mechanism 7 one side after that, the microorganism filter residue after will mixing the adhesion agent rolls from the mixed grain collecting pipe 71 that the slope set up and falls to mix collecting barrel 74 in, wait for the pelletization, at this in-process, retrieve the microorganism filter residue disintegrating slag of the in-process that rolls through filter layer 72, reach the effect of recycle health filter residue disintegrating slag, reduce the loss of granule microorganism charcoal in raw and other materials preparation process.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
