Electroplating wastewater more toxic and harmful. Livestock such as cyanide can cause acute poisoning, death, long-term effects of low concentrations can cause chronic poisoning. Cadmium can occur kidney disease, and can cause disease bitterly. Hexavalent chromium can cause lung cancer, gastrointestinal disorders and anemia electroplating wastewater treatment Pharmacy, and will accumulate in the bone, spleen and liver. So electroplating wastewater treatment works, electroplating wastewater must be strictly controlled and properly handle. The main source of electroplating and metal processing industry wastewater zinc plating or pickling liquid entrainment. Metal contaminants by rinsing process and transferred to the rinse water. Pickling process involves metal (zinc or copper) was first immersed in acid to remove the oxide surface, followed by immersion brightener containing chromic acid were strong credit processing. The wastewater contains large amounts of hydrochloric acid and zinc, copper and other heavy metal ions and organic brighteners, toxic wastewater, some also contain carcinogenic, teratogenic, mutagenic, toxic substances, great harm to humans. Therefore, electroplating wastewater treatment must be carefully recycled, so eliminating or reducing its pollution of the environment. Sihui City, South River electroplating electroplating wastewater treatment projects focus (6000m3 / d): electroplating wastewater treatment of heavy metal ions and COD is not stable compliance usually because chromium and cyanide wastewater treatment did not fully integrated into the water, the waste water is easy to form heavy metal ion or organic complexes, increasing the difficulty of integrated water treatment. And most manufacturers are using ordinary chemical electroplating wastewater treatment company, which no significant effect on the processing complex. 1. heavy metal ion complexation of heavy metal ions wastewater treatment, usually in the treatment of heavy metal ions adding a relatively strong ability to capture heavy metal scavenger agents ---- (SMET). Heavy metal scavenger waste water containing heavy metal complexes have a significant effect on the ordinary heavy metal wastewater treatment is able to lower levels of heavy metal ions. PH in use instead of caustic soda and powder, make it easier for heavy metal ions to form a precipitate, and the water quality is better. 2.COD treatment approach: adding to the reaction tank SCOD removal agent.
