    摘要： A system and method treat oilfield produced water by two-stages of hazardous sulfide treatments. In an embodiment, a two-stage oil and gas field produced water treatment system includes an oil removal vessel. The oilfield produced water is introduced to the oil removal vessel. The oil removal vessel removes a portion of the hydrocarbons from the oilfield produced water to provide a reduced oil produced water. In addition, the system includes an iron sponge. The reduced oil produced water is introduced to the iron sponge, and the iron sponge removes a portion of the hazardous sulfides from the reduced oil produced water to provide a reduced sulfide produced water. The system also includes a stabilized sodium percarbonate solution. The stabilized sodium percarbonate solution is mixed with the reduced sulfide produced water to remove a portion of the hazardous sulfides from the reduced sulfide produced water to provide a treated produced water.

    摘要： A wastewater treatment process by an electrochemical apparatus, said apparatus having at least an electrochemical electrode (30), and said electrochemical electrode (30) having suitable electrode plates comprises the following steps: passing high concentration wastewater containing undesirable solutes through at least one electrochemical electrode (30) to which a DC electrical current is applied to destroy the undesirable solutes in the water intake, so as to output water having a lower concentration of the undesirable solutes; the DC current applied to the electrochemical electrode (30) comprises at least a constant potential difference stage exerted on both ends of the electrochemical electrode (30), and followed by a constant current stage through the electrochemical electrode (30).
