At the same time, the sediment after sewage treatment needs to be dried and difficult to handle.

So the invention has a multi-powder, high magnetic U-containing graphite sequins and other floating material characteristics of the furnace resource processing method, which in turn contains -200946688 5 ❹ 10 15 ❹ material steps, a stable a step of granulating, a step of magnetic separation, a step of mixing, a step of discharging, and a step of discharging; wherein the slag is subjected to a stabilization reaction with water, and a preliminary screening step is performed to select a suitable particle size range, and The magnetic separation step sorts out two types of non-magnetic slag and magnetic slag, and then performs the mixing agglomeration step and the discharging step for the non-magnetic slag, so that the slag containing graphite sequins and the like can be solved, except to avoid Environmental pollution problems that may occur during production and application processes' and effectively improve the quality of the slag. [Embodiment] The foregoing and other technical contents of the present invention, The details of the preferred embodiments of the present invention will be apparent from the following detailed description of the preferred embodiments of the present invention. Referring to Figure 2, a preferred embodiment of the present invention has a multi-powder, high magnetic material and The slag resource treatment method 3' of the floating property of graphite sequins mainly comprises a preparation step 31, a stabilization step 32, a preliminary screening step 33, 35, and a discharge step % step 32 and the conventional phase. A magnetic separation step 34, a mixing and agglomeration step 'where 'the preparation step 31 and the stability of the same' will not be described in detail. Continued to say 'the first boat 八本峨. 步 step knife step 33 in this embodiment The middle system utilizes a slanting sifter 331 for screening of the slabs, and the slanting sump 331 has a single layer division and is designed with a large interval to remove the aforementioned preliminary stability: the grading according to the remaining size Sorting; in addition, the magnetic separation step 34 is magnetically selected in the present embodiment by using a 'H Ufc 0^1 sorting machine 341, so as to reduce the weight of the powder in the preliminary screening step 33. The desulfurization slag is placed in the magnetic separation. 20 200946688 5 ❹ 10 15 The machine 341 performs magnetic separation to sort out non-magnetic desulfurization slag (usable furnace stone) and magnetic desulfurization slag; and the mixing agglomeration step 35, which is to perform the non-magnetic After the desulfurization slag is collected, the desulfurization slag is still contaminated with impurities (such as graphite sequins, dust, etc.), and then the curing agent is added to stir and solidify the solidified desulfurized slag, which may of course be directly formed into a particle size. The smaller block shape and the block of the desulfurization slag may be appropriately sized according to different uses such as the road grade S, or the block of the desulfurized slag may be further crushed for subsequent treatment. Finally, the discharging step 36 is to classify and package the desulfurization slags in the above-mentioned step, and to be processed and applied by the industries in different fields. In particular, in the preliminary screening step of the present embodiment, the desulfurization process can be carried out by using the crushing step 37 in order to make the particle size of the desulfurized slag. The magnetic material remaining in the desulfurization (four) portion exists after the crushing of the desulfurization slag is prevented. Therefore, after the crushing step 37 described above, a preliminary magnetic separation (four) 38 is additionally provided to make the magnetic force. The attraction method performs the magnetic separation sorting 'removal operation, and the desulfurization of the non-magnetic material is continued to proceed to the next step. Referring to Fig. 2', in the operation of the embodiment, the desulfurization slag (i.e., preparation step 31) generated after the refining is prepared, and the desulfurization and desulfurization are sprayed and treated to react the desulfurization with water. After the disintegration, preliminary safety::reaction (ie, stabilization step 32), and then the desulfurization slag is screened according to the particle size = small (ie, preliminary screening (four) 33), of course, for the granules _, can be further passed through the crushing step 3?, to reduce 20 200946688 5 ❹ 10 15 ❹ • 20 to lower the particle size specifications of the desulfurization slag, and magnetically magnetize the magnetic substances in the desulfurization slag (ie, preliminary magnetic separation step After 38), the desulfurization slag can be re-sorted through the preliminary screening step 33, and the desulfurized slag having a smaller particle size obtained through the preliminary screening step 33 is again placed in the magnetic separator. In 341, the magnetic substance in the desulfurization slag is removed (i.e., magnetic separation step 34). Continuing with the above, the amount of the non-magnetic desulfurization slag after the above-mentioned treatment steps is greatly reduced, and at this time, the non-magnetic desulfurization slag (the gratestone for resource utilization) can be further Efficiently, that is, to improve the quality of the desulfurization slag, which is contained in the graphite sequins, dust and other impurities in the desulfurization slag, and then a curing agent is added to carry out the mixing. The desulfurization slag utilizes the consolidation action of the curing agent to form the desulfurization slag into a block shape (ie, the mixing agglomeration step 35), so as to mix the plurality of graphite sequins, dust, etc., which are intercalated in the desulfurization slag. In the desulfurization slag which is solidified and sealed in a block shape, the graphite sequins are effectively prevented from being flying during the treatment of the desulfurization slag, and are adhered and adhered to the dislocations, and finally the above In the step, the solidification block is used to break the classification package for processing in different fields (ie, discharge step 36). From the above description, the present invention is solid and has the advantages listed below and the present invention in view of the slag (i.e., useful gazette) after the classification and separation, the curing agent is used. The complex graphite sequins, dust and other impurities that are not mixed in the slag are in the collapse of the solidification material 8 200946688 in the block shape to effectively prevent the graphite sequins from flying during the processing of the furnaces. , which in turn caused air pollution problems. Continuing the foregoing, since the present invention performs subsequent processing on the non-magnetic slag, it is more efficiently processed for the slag, and 5 ❹ 10
