The company has a profound understanding and rich practical experience of mainstream processes such as A²/O, two-stage A/O, improved SBR, and MBR. Especially in the treatment of high-concentration organic wastewater, the company's "pre-acidification + high-efficiency anaerobic + improved two-stage A/O" combined technology is particularly outstanding. It can effectively remove COD and achieve biological denitrification, laying a solid foundation for subsequent advanced treatment.
