| Detailed Product Description: | Electroplating wastewater discharge standards for the electroplating enterprises water and air pollutant emission limits, monitoring, and monitoring requirements. And to promote regional economic development, promote the adjustment and transformation of economic growth mode of economic structure, guide the development of electroplating production process and pollution control technologies, wood standard specifies mouth water pollutant discharge limits electroplating enterprises particularly malodorous emissions of pollutants, applicable environmental noise corresponding national pollutant discharge standards, resulting in the identification of fluid waste treatment and disposal of solid waste pollution control applicable national standards. Since the implementation of the standard self-mouth timber, electroplating enterprises water and air pollutant emission control executed in wood standards, no longer performs "Integrated Wastewater Discharge Standard" (GB8978-1996) and "Air Pollutant Emission Standards" (GB16297- the relevant provisions of 1996) in. Electroplating is one of the world's three major polluting industries electroplating wastewater treatment equipment, with the rapid development of China's township enterprises in electroplating wastewater electroplating process, our plating pollution problems have become more serious. Electroplating plants (or plant) effluents and waste. Including plating rinse water, waste bath, wash equipment cooling water and ground water. Water quality due to the production process varies, generally divided into wastewater containing cyanide (cyanide concentration of 20-70mg / L), waste water containing chromium (chromium-containing concentrations of 20-100mg / L) and heavy metals, acid and alkali, surfactants three wastewater systems. The main wastewater containing heavy metal ions (copper, nickel, zinc, tin, chromium, etc.), BOD small, not much suspended solids. Now often used chemical method (neutralization precipitation, redox, ferrite, etc.), physical chemistry method (electrolysis, ion exchange, membrane separation, etc.) and concentrated by evaporation method for wastewater treatment. The main source of electroplating and metal processing industry wastewater zinc plating or pickling liquid towing. Contamination by metal rinsing process has shifted to the rinsing step includes metals (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 towel zinc, copper and other heavy metal ions and organic brighteners, greater toxicity, and some also contain carcinogenic, teratogenic, mutagenic toxic substances electroplating wastewater reuse, great harm to humans. Therefore, the electroplating wastewater must be carefully recycled, so eliminating or reducing its pollution of the environment. Electroplating wastewater, rich students, electroplating wastewater process provided by the Environmental Protection Engineering Co., Ltd. Guangzhou Fu students. Guangzhou Fu students Environmental Engineering Co., Ltd. (www.fsyhb.com) in the field of environmental monitoring equipment devoted boundless enthusiasm and passion, rich students has been customer-centric, the concept of creating value for customers, quality, service to win market, and sincerely hope to cooperate with the community to create a successful, create brilliant.
