Description of the invention: [Technical field to which the invention pertains] The present invention relates to a surface treatment method, and the side is made of a chemical money copper. [Prior Art] With the electroless rhodium plating, the chemical fine method has been opened. = Plastic surface anti-treatment and PCB board surface financial industry. And] = / dry mining method towel, rinsing ji parts process towel produced wastewater @ containing heavy metal Cu2? Must be treated before recycling or discharge. Although the traditional chemical sinking method can remove metal ions from wastewater, it still produces a need for professional n mud, which is unfavorable. In view of the above problems, the present invention provides a chemical clock copper loop processing method which combines chemical bond copper with ion exchange and reverse osmosis technologies to form a sinus closed circuit®, in most of Chen Gold; the source is without ship and wastewater discharge. The invention provides a German processing method, and the processing steps included in the towel are: firstly, the pre-treatment of the copper workpiece to be removed to remove the grease and oxide film layer of the copper surface and clean the surface thereof. Then, the workpiece is immersed in a copper plating solution for _ treatment; then the copper-plated workpiece is immersed to collect a portion of the copper material, and then the third-stage countercurrent rinsing is performed, and the surface plating solution of the workpiece surface is washed with a large amount of trees. 'This part of the wastewater with heavy metals generated does not meet the emission standards' must be thief; therefore, the final secret of the above-mentioned rinsing water to adjust the PH value to 2~10, and then through the ion exchange resin, so that the heavy metal ions in the wastewater f The father exchanges the same type of ions in the resin to recover the heavy metal resources in the wastewater, and then undergoes an ultrafiltration step to remove the macromolecular impurities contained in the wastewater, and then reverse osmosis treatment, and the unpurified The wastewater is separated and sent directly back to the initial rinse wastewater for loop processing, while the purified scrubber is used directly to rinse the workpiece. The electroless copper plating loop treatment method itself has formed a closed loop, and the recovered 1333986, the metal and water can be further paste, basically realizes the zero hearing of the waste water, avoiding its manufacture or % environmental pollution. In order to further understand the object, structural features and functions of the present invention, the level matching diagram is described in detail as follows: [Embodiment] The method for processing a chemical ore copper loop provided by the present invention is as shown in FIG. The processing steps included are: /,

The waste water with heavy metal generated by the sickle does not meet the discharge standard and must be disposed of. e. The rinse waste water recovery treatment S5~S11, the process is specifically to adjust the pH value S5 to adjust the pH value to 3~ 10, then ion exchange S6, using the characteristics of ion exchange resin, the heavy metal ions of the wastewater + exchange with the same type of ions in the exchange resin, in order to recover the heavy metal Deng in the wastewater, ^ ultrafiltration S7, through half of the membrane to remove After the wastewater _ contains macromolecules, it passes through - reverse osmosis to S8, (10) the purified wastewater purified by the purified silk enters and separates, and the obtained purified water can hardly detect the presence of copper ions, and the water can be directly used. The slewing cylinder S1 丨, and the waste water purified by the other wire is discharged into the untreated wastewater by the concentrated water circulation treatment S10', and the wastewater is retreated, so that the waste water can be basically reduced to zero.
