Water quality plating electroplating production process and all of its production process is generally: after etching treatment a part of a plating bath sink a recovery tank of a clear water rinse. This section comes mainly from the rinse process wastewater, wastewater from the corresponding metal-containing or cyanide, copper cyanide rinse in water containing cyanide and copper ions; rinse water containing hexavalent chromium; nickel plating rinse water containing nickel ions. Wash water for treatment, depending on the water diversion plating species, such as the diversion of wastewater containing cyanide after breaking through two cyanide, adjusting the PH value of electroplating wastewater, solid-liquid separation can discharge standards; chromium-containing waste water diversion through the reduction reaction, and then through the and after solid-liquid separation can meet emissions standards. This step is mainly dry storage and natural means of mechanical energy, thermal energy electroplating rinse water after drying parts of the surface to prevent rust and damage the oxide film. The segment step no wastewater discharge. Stripping stripping process are chemically impregnated anode electrolytic plating wastewater treatment equipment both methods, the process is: unqualified plating -> stripping tank -> recovery tank -> Clear the sink -> rinse. The section between PH 2-6 wastewater, wastewater mainly from rinse water receded after plating. Stripping rinse water can enter their own wastewater treatment pools, but not directly into the wastewater treatment pond two should be mixed after pretreatment alone wastewater discharged into the corresponding tributary. Electroplating wastewater treatment equipment electroplating wastewater treatment equipment by regulation pool, plus kits, restore the pool, neutralization tank, pH adjusting tank, flocculation, Sedimentation, Van filter, clean water tank, flotation reaction, activated carbon filters and other components. Process Description: passivation concentrate with lift pump will concentrate input to restore the pool electroplating wastewater reuse, through a metering pump sulfuric acid was added to restore the pool, so reducing the pool pH of 2-3, and then through the metering pump reductant sulfite was added to restore the pool, will reduce hexavalent chromium to trivalent chromium. After passivation solution and pre-treatment reduction treatment, zinc, nickel washing water into the large adjustment in the pool, in the regulation of various waste water tank after sufficient homogenization lift pump upgrade to a reaction by the pool, through the metering pump into the CaCl2, to destroy the Zn2 + complex in the reaction vessel 2 through a metering pump into the NaOH to adjust the pH value within the range of 9-11, and then electroplating waste water into the reaction tank for waste water 3, through the metering pump into the coagulant After the PAM into the inclined plate sedimentation tank, forming a sludge metal hydroxide sludge bucket sink, and in the supernatant gravity into the pool pH adjustment, transferred back to a pH in the 6-9 range, and then discharged. Inclined plate sedimentation tank sludge periodically discharged into the sludge tank, after treatment with Van filter cake Sinotrans deep, sludge water return regulation pool.
