Recently, the treatment for pesticide wastewater, experiments, research the management process of biochemical combination, so that the treated water meet the emission requirements. With the development of industry, containing toxic or refractory organic compounds in more and more Many traditional, physical and biological treatment methods to achieve the ideal processing effect, how to deal with the organic matter in waste water, improve the treatment effect has become an important subject of wastewater treatment industry. Fenton oxidation method is an advanced oxidation technology, which can be used as a pretreatment of wastewater treatment, and can be used as the final wastewater treatment. The reaction is the essence of chain reaction catalyzed oxidation of Fe2+ and H2O2 strong OH radical. In the traditional wastewater treatment technology and hard biodegradation of wastewater treatment, this method has simple operation, fast reaction speed, low cost and other advantages, has been widely used in printing and dyeing, coking, pesticide wastewater treatment. So Fenton reagent has a broad application prospect in wastewater treatment, more and more attention from home and abroad. Keywords: wastewater, pesticide plant in Fento
