Description

TECHNICAL FIELD

[0002] Micro-arc oxidation is also known as plasma electrolytic oxidation, which is developed on the basis of anode oxidation technology, and the formed coating is superior to anode oxidation. During the production of micro-arc oxidation products and the cleaning process of the micro-arc oxidation products after the production is completed, a large amount of wastewater is generated, most of which contains a large amount of pollutants, and therefore needs to be treated before being discharged.

[0003] During the micro-arc oxidation sewage treatment process of most manufacturers, the sewage is usually discharged into a tank pool, and a medicine is added to the sewage to make the pollutants and impurities in the sewage precipitate, and then the precipitates are uniformly collected.

However, during the stirring process, the sewage around the stirring rod flows fast, the liquid flow speed near the corners of the tank pool is slow, the sewage and the medicine in the tank pool cannot be quickly mixed, and the slow liquid flow speed near the corners of the tank pool is easy to cause the precipitates in the sewage to deposit, and a large amount of precipitates are easy to remain when the sewage and the precipitates are transferred out of the mixing tank.
