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 board sewage treatment, the formation of a buffer system, pH can not be adjusted up, heavy metal scavenger to the Under alkaline conditions, pH adjustment can not can not handle nickel. At this time, the first being the phosphite oxidation of phosphorus, plus PH regulator can adjust the PH up heavy metal complement agent manufacturers, plus phosphorus and heavy metal scavenger agent can put excessive high phosphate wastewater treatment standards. 1. Use heavy metal scavenger waste water samples taken heavy metal complement agent market 500ml measured water PH value, if the water PH value is greater than 3, can be directly cast heavier metal scavenger solution 0.5ml to 1000ml waste water samples, reaction 3 to 5 minutes; (if waste water PH value of less than 3, is required to adjust the PH value to 7-9 in advance after, heavy metal scavenger solution was added 0.5ml to 1000ml waste water samples, the reaction for 3-5 minutes.) 2. Equilibrium water, adjust the PH value to an appropriate range 7-9. 3. coagulant poly aluminum (HX203) 0.5ml / 1000ml, the reaction was stirred for 1-2 minutes. 4. The coagulant dosing 0.2% polyacrylamide (anionic) 0.5ml / 1000ml, with rapid stirring for 1-2 minutes. 5. The reaction was allowed to stand for 5-10 minutes after the completion of analysis and detection filter water filter paper targets.
