Abstract

The invention provides a deep ozone oxidation treatment device for pesticide chemical wastewater. Comprising a catalytic oxidation reaction tank, an ozone generator used for supplying ozone to the catalytic oxidation reaction tank, a PH adjusting tank used for inputting wastewater to the catalytic oxidation reaction tank, an ozone tail gas destructor used for treating tail gas of the catalytic oxidation reaction tank, and a drainage tank used for receiving the wastewater treated by the catalytic oxidation reaction tank, the ozone generator, the PH regulating tank, the ozone tail gas destructor and the drain tank are all connected with the catalytic oxidation reaction tank. The method has a good treatment effect on pollutants, chromaticity and the like in pesticide chemical wastewater, and can effectively solve the deep treatment problem of comprehensive wastewater.

Description

technical field [0001] The invention relates to the technical field of advanced wastewater treatment, in particular to a device and a process for the deep ozone oxidation treatment of pesticide and chemical wastewater. Background technique [0002] The ozone advanced oxidation method has been applied to the treatment of various industrial sewage. Japan and the United States and other countries applied this method to the treatment of urban sewage in the 1980s, and France has also applied the O3 / H2O2 advanced oxidation method with other technologies. Combined application in sewage treatment. At present, there are many domestic use of this method to deal with a large number of refractory organic sewage. For example, using O3 / H2O2 to pretreat pyrimidine wastewater and petrochemical wastewater, it is found that the pretreatment of this method can significantly improve the biodegradability of wastewater while treating COD. In addition, some research data show that the O3 / H2O2 ad...
