This invention belongs to the field of wastewater treatment technology, specifically a method for treating medical wastewater by synergistically removing new pollutants and pathogenic microorganisms. The method includes the following steps: S1, Pretreatment: Inorganic flocculants are added to the medical wastewater to promote the aggregation and sedimentation of suspended particles and colloids; S2, Oxidation Treatment: A composite agent is added to the pretreated medical wastewater while a direct current electric field is applied. The composite agent includes potassium persulfate, aminosulfonic acid, sodium chloride, sodium bromide, surfactant, pH buffer, composite corrosion inhibitor, anti-caking agent, and anhydrous sodium sulfate. After dissolving, the composite agent generates a strong oxidizing component that mineralizes and decomposes organic matter while killing pathogens; S3, Biochemical Treatment: The oxidized medical wastewater is then subjected to biochemical treatment to remove ammonia nitrogen and small molecule organic matter. This invention can effectively decompose various new pollutants and inactivate pathogenic microorganisms, thus improving the treatment effect.

This invention discloses an aftertreatment assembly, a vehicle, and a vehicle control method, belonging to the field of vehicle technology. The aftertreatment assembly comprises a pre-stage SCR, an MOC, a DPF, a post-stage mixer, and a post-stage SCR, sequentially connected along the exhaust gas flow direction. That is, the aftertreatment assembly has two stages of SCR, thereby improving its ability to reduce nitrogen oxides and adapting to higher engine exhaust emissions, thus enhancing exhaust gas purification. Simultaneously, the ratio of platinum to palladium in the oxidation catalytic coating of the MOC is greater than 12:1, resulting in stronger oxidation capabilities for CO, NO, and HC in the exhaust gas. This not only provides more NO2 for DPF regeneration, thus improving DPF functionality, but also further enhances exhaust gas purification.
