Electroplating wastewater composition is very complex heavy metal scavenger phosphorus scavenger, in addition to cyanide (CN-) of heavy metals in waste water and waste acid scavenger patented technology Gold River, heavy metal wastewater is potentially a great danger electroplating industry wastewater categories. Heavy metals contained in waste water according to the classification of heavy metals in general can be divided into chromium (Cr) wastewater containing nickel (Ni) wastewater containing cadmium (Cd) of wastewater containing copper (Cu) water, zinc (Zn) water, gold (Au) wastewater containing silver (Ag) wastewater. Ingredients difficult to control, some are carcinogenic, teratogenic, mutagenic toxic substances. Heavy metals in waste water (such as wastewater, waste circuit boards, etc.) are the traditional approach of lime or alkali to adjust the PH to the night between 8-11 to remove the separation of heavy metals, but as wastewater containing chelating agents such as EDTA, this chelating agent and heavy metal ions can form a covalent compound solubility of, but can not completely precipitated, isolated heavy metal heavy metal scavenger solid, so will not be able to meet environmental emission standards; heavy metal chelating agent is especially designed for this problem of product , effect is good. Process comparison: A, ferrous sulfate reduction precipitation method: someone with ferrous sulfate precipitation method to deal with such reduction containing chelated copper ions waste water, but the method complicated, pH value adjustment require two steps to disrupt copper chelate, And a very great amount of sludge produced. B, field also handle such waste water by ion exchange, initially works well, water quality can be reused; however, ion exchange penetrating point difficult to grasp, are often penetrating run and difficult to find. After a period of time, since the printed circuit board wastewater contains strong oxidants and many organic compounds, chelating resin will quickly deteriorated and pollution, ion exchange capacity decreased heavy metal scavenger, regeneration is difficult to restore the water gradually to meet the criteria . C, using the heavy metal chelating agent Saatchi solid sulfide precipitation process waste water containing heavy metal chelating agents, due to various heavy metal sulfide solubility product is very small, heavy metal removal with good results.
