Why excessive high phosphate wastewater difficult to handle? High phosphorous electroless nickel waste more intractable, because wastewater containing phosphite this complexing agent. To phosphorus and nickel pH must be adjusted up, but because of the presence of phosphite in water, has two hydroxyl groups per phosphite, form a buffer system, pH can not be adjusted up, down to heavy metal scavenger in alkaline conditions use, can not adjust pH can not handle nickel. At this time, the first being the phosphite oxidation of phosphorus, plus PH regulator can adjust the PH up, plus phosphorus and heavy metals scavenger agent can put excessive high phosphate wastewater treatment standards. This year, the country launched a site of heavy metal pollution survey of industrial enterprises. Staff survey revealed that from existing monitoring results, the presence of heavy metal contamination in some places the circuit board sewage treatment, mainly in-house production facilities involving heavy metal surrounding area. Involving heavy metal heavy metal ion scavenger enterprises, mainly in terms of the electroplating industry. Heavy metals in wastewater (eg 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 heavy metal heavy metal separation complement agent market, but as wastewater containing chelating agents such as EDTA When such a chelating agent with the heavy metal ions to form a covalent compound solubility, the precipitation of heavy metals can not be completely, it will not meet environmental emission standards; heavy metal chelating agent is especially designed for this problem, the effectiveness is good. Heavy metal ion scavenger, Xuancheng heavy metal complement agent, Hubei Saatchi Saatchi provided by the Hubei Environmental Engineering Limited. Environmental Engineering Co., Ltd.
