Abstract

The invention provides a device and a method for deeply treating oxadiazon production wastewater and relates to the technical field of sewage treatment. The device comprises a pre-settling tank, a micro-electrolysis reactor, a flocculation tank, a decoloring tank, an ozone generation device, a MVR evaporator, an A / O biochemical tank and an electrocatalysis oxidation tank. The method is formed by effectively combining settling treatment, microelectrolysis, flocculation settling, decoloring process, MVR evaporation process, A / O process and electrocatalysis oxidation process. The device and the method are good in effect of reducing wastewater pollution, low in cost and high in safety coefficient.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a device and method for advanced treatment of waste water produced by oxazoram. Background technique [0002] While the pesticide production industry continues to develop, the water bodies around the pesticide manufacturing enterprises are also seriously polluted. Oxazoyl is a heterocyclic selective contact herbicide, and its pure product is a white odorless crystal. Soluble in various organic solvents, hardly soluble in water. Stable at room temperature, easy to decompose under alkaline conditions, low toxicity to humans, livestock, and bees, and moderate toxicity to fish. During the production of diazoram and similar pesticides, the wastewater produced has the characteristics of high salt content, high chemical oxygen demand, high chroma, and high toxicity. Traditional microbial treatment methods are usually used for treatment. Traditional microbial treat...
