Effective Factors of Degradation of Pesticide Wastewater by Mg-Zn-Ca Amorphous Ribbon

Abstract

Abstract. In order to effectively degrade pesticide wastewater with high concentration and difficult degradation use Mg-Zn-Ca amorphous ribbon as metal catalysts. Catalytic degradation of Pesticide wastewater by Fenton like method. And tracking system chemical oxygen demand (COD). The effects of the amount of catalyst, the amount of H 2 O 2 and the amorphous composition on the catalytic degradation reaction are discussed. The results show that the degradation of COD in wastewater is the best and the removal rate of COD can reach 65% when the amorphous dosage is 0.3 g and the amount of H 2 O 2 is 2 ml in the 100 ml wastewater. With the increase of Mg content in amorphous alloy, the degradation efficiency can increased gradually.
