Heavy metal scavenger specification content: 15% -20% 40% -45% Factory Size: plant area of ??12,000 square meters warehouse area of ??600 square meters Production capacity: 800 t / month heavy metal scavenger can fully capture or heavy metal chelate heavy metals, so that it can precipitate separated, meet environmental emission standards. For most of the heavy metal ions (Cu, Zn, Hg, such as chrome-nickel cadmium vanadium and manganese, tin, etc.) can be applied. Direct reduction of hexavalent chromium to trivalent chromium and precipitation. Widely used in the electroplating industry, circuit boards, electronic industry, non-ferrous smelting iron and steel industry, chemical industry, waste incineration plants, battery plants and other heavy metals exceeded the sewage treatment industry. Color chemical chelating precipitation resulting metal precipitate Cu2 + brown, Ni2 + yellowish green, Pb2 + white, Zn2 + cream, Cd2 + white, Hg2 + white, Cr3 + khaki, Fe3 + / Fe2 + light brown, Al3 + core light brown of the technology Spirit is the use of solid heavy metal scavenger. As long as the Spirit of solid heavy metal scavenger investment and added electroplating wastewater, the Spirit of solid heavy metal scavenger can be at room temperature, rapid response powdered heavy metal scavenger and wastewater Cu2 +, Ni2 +, Zn2 +, Cr3 +, Pb2 +, Mn2 + and other heavy metal ions, generated water-insoluble salt chelating heavy metal ion trapping agent, then adding a small amount of PAC and PAM, you can remove heavy metals in electroplating wastewater. The biggest advantage of this technique is applicable to a wide pH range, are valid in the range of 3 to 11. Further removal of heavy metal ions adsorbent, the technology heavy metals from wastewater complex is also very good. However, after the external drainage treatment compliance, due to the presence of salt and should not be directly recycled into the production of key plating. Traditional chemical precipitation process is to add a base. However, due to the different heavy metal ions hydroxide precipitate was generated when the optimum pH is different, and some heavy metal ions may form complexes with other ions in solution (which increases the solubility in water), so the effect of treatment is often not ideal. High concentrations of heavy metals in waste water residue.
