[0002] Stainless steel washing wastewater needs to undergo physical and chemical treatment and biochemical treatment in sequence. After the physical and chemical treatment is completed, the stainless steel washing wastewater needs to undergo biochemical treatment before it can be discharged or reused. At present, there is still a lack of biochemical treatment system with reasonable structure and good effect. At the same time, the physical and chemical treatment is completed. Finally, the pH of the flushing wastewater is often acidic or alkaline, and there may be flocs in the flushing wastewater. If the biochemical treatment is directly performed after the physical and chemical treatment is completed, the effect of the biochemical treatment may be affected, and even the biochemical treatment may fail.
