This invention belongs to the field of wastewater treatment technology, specifically relating to a method and apparatus for removing COD from high-salt, high-organic-content wastewater. The removal method employs two organic matter retention membranes connected in series to treat the high-salt, high-organic-content wastewater. By controlling appropriate process conditions, these organic matter retention membranes primarily retain organic matter while retaining as little salt as possible, ensuring stable operation of subsequent processes or achieving compliant wastewater discharge. Furthermore, the concentrate obtained after treatment by each organic matter retention membrane is returned in a specific proportion to the inlet of the membrane that produced the concentrate, thereby ensuring efficient and stable membrane operation, improving system recovery rate, and extending membrane lifespan. This invention achieves COD removal from high-salt, high-organic-content wastewater using only a single process, exhibiting high removal rate, good decolorization effect, and high recovery rate. It significantly shortens the process flow and is characterized by being green, efficient, energy-saving, environmentally friendly, and highly reliable.

This application relates to the field of vehicle control, specifically to a control method, device, and vehicle for an in-vehicle panoramic imaging system. By detecting negative obstacles in the vehicle's surrounding environment, this application can promptly identify potential hazards. When a negative obstacle is detected, the in-vehicle panoramic imaging system is activated and marked, allowing the driver to clearly understand the obstacle's location and preventing vehicle damage or accidents due to neglect, thus improving driving safety. The system continuously monitors the display of negative obstacles in the panoramic imaging system and deactivates the image based on whether the obstacle no longer exists or has been confirmed eliminated. This ensures that the panoramic imaging system functions effectively when a hazard exists and can be deactivated promptly after safety, avoiding resource waste.

The utility model discloses a sealing structure of a large-caliber plastic bucket, which comprises a bucket body and a bucket cover which are matched with each other, the bucket body is in threaded connection with the bucket cover, a convex rib is arranged on the bucket cover, a sealing groove matched with the upper edge of the bucket body is formed on the bucket cover, a first sealing line is arranged on the inner side of the sealing groove, and a second sealing line is arranged on the outer side of the sealing groove. A second sealing line is arranged at the top of the sealing groove, a third sealing line is arranged on the outer side of the sealing groove, a fixing buckle is arranged on the periphery of the barrel cover, a protruding block is arranged on the periphery of the barrel body, and the fixing buckle is provided with a buckling groove matched with the protruding block.
