摘要：
폐수로부터과산화수소농도를감소시키는방법은폐수를폐수보다낮은과산화수소농도를갖는물로희석하여희석된폐수를생성하는단계, 희석된폐수를산성 pH에서용해된철 화합물과접촉시켜희석된폐수보다낮은과산화수소농도를갖는부분적으로처리된폐수를형성하는단계, 및부분적으로처리된폐수의 pH를상승시킴으로써철 고체를부분적으로처리된폐수로부터침전시켜중화된부분적으로처리된폐수를형성하는단계를포함한다.
摘要（英）：
A system (100) for removing hydrogen peroxide from wastewater, the system comprising: a first reaction tank (135) having an inlet fluidly connectable to a source of the wastewater; a source of dilution water (105) having a lower concentration of hydrogen peroxide than the wastewater in fluid communication with the inlet of the first reaction tank; a source of ferrous salt in fluid communication with the first reaction tank (140); a source of acid in fluid communication with the first reaction tank (145); a second reaction tank (150) having an inlet in fluid communication with an outlet of the first reaction tank; and a source of a base in fluid communication with the second reaction tank (155).
