Abstract

The invention discloses a pesticide wastewater treatment process and a treatment device thereof. A process system comprises a Fenton oxidation tank, a regulating tank, a hydrolysis acidification tank,a pre-anoxic tank, a CASS tank, an efficient sedimentation tank, an ozone catalytic oxidation treatment unit, a biological aerated filter and a disinfection tank. The invention aims at the characteristics of high organic matter concentration, complex components, high chromaticity, strong toxicity, extremely poor biodegradability and the like of pesticide wastewater. A combined process combining anovel advanced oxidation technology, a traditional physical and chemical process and a biological technology is adopted, the removal effect on refractory organics is good, the deodorization and decoloration capacity is high, and effluent can meet the first-grade A emission standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant GB18918-2002 and is discharged into a receiving water body.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a pesticide wastewater treatment process and a treatment device thereof. Background technique [0002] my country is a big country in the production and use of pesticides. The waste water produced by the production of pesticides is countless every year, and most of the pesticide wastewater is directly discharged into the water body without treatment or without treatment up to the standard, which seriously pollutes the water body and destroys the natural environment. [0003] Due to the backwardness of pesticide production technology and old production equipment, a large amount of waste of raw products has been caused. Most of the wastewater contains toxic and harmful substances such as benzene, phenol, and arsenic. High, strong toxicity, extremely poor biodegradability, and large fluctuations in water quality and quantity. Most of the existing sewage treatment pro...
