Integrated treatment process of 3, 6-dichlorosalicylic acid synthetic wastewater

The invention discloses an integrated treatment process for 3, 6-dichlorosalicylic acid synthetic wastewater, and the defect that an existing process technology system is unstable in operation is overcome. The specific process comprises the following steps: sequentially carrying out homogenization, Fenton oxidation, electric flocculation air flotation treatment, advanced precision filtration, electrocatalytic oxidation and DTRO water treatment on the 3, 6-dichlorosalicylic acid synthesis wastewater, so that the serious secondary pollution phenomenon after treatment is reduced, the discharge amount is reduced, the near-zero discharge purpose is realized, and the water resource is further saved. The invention provides a stable combined system process technology. The wastewater treated by theprocess disclosed by the invention can reach the national discharge standard, the process has the process advantages of high treatment efficiency, water resource saving, stable operation, conveniencein maintenance and the li
