Printed circuit board manufacturing process wastewater, which is a lot of copper, a very small amount of lead, tin, gold, silver, fluorine, ammonia, organic and organic complexes. As for the process to produce copper wastewater, are: Shen copper, copper plating the entire board, graphics copper plating, etching, and before various PCB treatment processes (chemical pre-treatment, the front plate brush handle, grinding plate before processing, etc.). Copper waste generated by the above process, according to their composition, can be divided into complex and non-complex waste water. In order to meet the national wastewater discharge standard heavy metal scavenger, where the maximum allowable emissions of copper and its compounds at a concentration of 1mg / l (by copper count now raise standards of 0.5), it must be for different wastewater containing copper, to take a different The wastewater treatment method is now widely used is supplemented with an appropriate amount of heavy metal scavenger. I produced the heavy metal scavenger has been widely used in circuit boards, PCB, electroplating enterprises discharge standards. To meet the business requirements of the latest emission standards. Environmental Protection Technology Co., Ltd. Hubei's Spirit of heavy metal scavenger solve complex and heavy metal-containing waste water treatment problems. It can respond quickly at room temperature, chemical waste and wastewater with heavy metal ions in heavy metal scavenger, water-insoluble salts of heavy metals in waste water scavenger circuit boards, a small amount of flocculant, the purpose of the formation of floc removal of heavy metals. By the use of proven, the process is simple and can be done after the coexistence of a variety of heavy metal ions first treatment, can meet environmental requirements; complex salts of heavy metals in waste water can fully play its role, and coarse flocculation, sedimentation fast Wastewater Treatment heavy metal scavenger, post-processing easy, stable, non-toxic, no secondary pollution, etc., can be used in a variety of wastewater treatment.
