Solid heavy metal scavenger application processing circuit board etching process in the treatment of wastewater in comparison: A \ ferrous sulfate reduction precipitation method: Someone to deal with such containing chelated copper ions of heavy metals in waste water scavenger price reduction with ferrous sulfate precipitation method, but complicated method, pH value adjustments need two steps to destroy the copper chelate, and a very great amount of sludge produced. B \ site also has an ion-exchange method to deal with such heavy metals in waste water scavenger manufacturers, initially works well, water quality can be reused; but penetration is not easy to grasp the point of ion exchange, are often not easy to find through the run. After a period of time, due to a printed circuit board wastewater contains strong oxidants and a variety of organic compounds, chelating resin will quickly deteriorate and heavy metal pollution scavenger, ion exchange capacity decreased, it is difficult to restore regeneration, water gradually to meet the criteria . C \ using solid heavy metal chelating agent treatment of wastewater containing heavy metal chelating agents, due to the heavy-metal sulfide solubility product is very small, heavy metal removal works well. Wastewater characteristics of the circuit board: board majority corrosion alkali etching liquid ammonia, the etching solution by means of oxidation, dissolution and chemical processes with the printed circuit board in the form of exposed copper dichloride tetraamine copper dissolution down produce large amounts of copper cleaning liquid waste and recycling tail. Such waste alkaline, NH. More copper to form copper complexes more stable presence of ammonia. Conventional treatment method is to use a hydroxide precipitation, but the presence of chelating agents in wastewater makes difficult to precipitate copper, so the application of solid heavy metal chelating agent is very necessary. The heavy metal sulfide scavenger polymer organic chelating agents, electroplating, circuit board industry wastewater containing heavy metal effects Pharmacy, at neutral PH can effectively remove heavy metal ions in wastewater heavy metal scavenger solids separation efficacy is Okay. Functions and features: 1. Simply put in the right amount to remove heavy metal ions, the method is simple, does not increase the cost of equipment that can be applied directly to the traditional chemical precipitation process. 2. Whether the concentration of heavy metal ions in wastewater level, can play removal. 3. When heavy metal ions coexist, once processed, while removing. 4. Add a small amount of large Austrian together, can generate good flocculation, sedimentation fast, pollution it produced less volume than the conventional method, and has a good dehydration.
