This technique generates large quantities¹O₂And very small amounts of OH and SO4^·-。¹O₂The life is relatively long, OH and the like, so that the wastewater treatment is more sufficient and the treatment efficiency is higher, and therefore, the method is more and more widely applied. At present, based on the reactor of this technique, during persulfate added to reaction chamber through independent device usually, need lay corresponding power unit and pipeline, the control of persulfate addition is also complicated relatively, and not only the occupation of land is wide, has improved the complexity of work progress, is unfavorable for practicing thrift the cost moreover.
