Description of the invention: [Technical field to which the invention pertains] The present invention discloses a metal age, a surface electric rainbow towel, which is contained in a recycling treatment liquid for electroplating waste liquid. Or recirculating electric town processing and reuse. Branch supplement; [prior art] in the = learning "mine tank" ^ more advanced electric ore waste metal recovery, loading in the electrolytic cell - group or array of flakes Yin = waste liquid is introduced into the electrolytic cell liquid metal ion ore on the cathode plate, _ over chemical, after the power is turned on, the waste is recovered. In this way, not only the recovery of the total number of products, but also the metal residue of the metal product can not be regenerated = the second part of the test is still in the face of the constant equipment cost, which is undoubtedly a heavy item. The fee is charged, and the large amount of recovery of the readers is recorded. The recordings are too high, and the dissolution is quick and the quality is reused, which obviously takes time and increases the recovery. The metal parts of the method must pass through [Invention] To improve the efficiency of metal recovery in the waste liquid of the electric ore; to reduce the chemical oxygen demand value of the waste liquid and to enter the solid-liquid separation 'waste liquid i The waste liquid is accelerated by the diagonal flow device (C), and the third treatment tank is introduced to introduce the second treatment tank; the tank introduces the waste liquid containing the high-grade metal into the second method. The concentration of the metal waste liquid is refluxed and the reverse osmosis membrane (RQ) is filtered. The F) module not only improves the waste liquid in the waste liquid, but also uses the surface area of the denier and even the spherical surface. Dazhi Electroplating Anode Replenishment Liquid is treated by filtration membrane (UF) module and reverse osmosis _(R〇) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ As shown in Fig. 1, the waste liquid containing metal deposition discharged in the recycling step (4) of the electroplating waste liquid of the present invention is mainly provided in the order of (a); the treatment tank i is lowered in the first treatment tank i The chemical oxygen demand of waste liquid depends on C0D, which is the most commonly used in water pollution. The number of 5% is in ppm _, and the acid value (PH) is 7~11. Control tone
