Currently, the most commonly used processes for treating dairy wastewater include biological contact oxidation, stand-alone aerobic treatment, anaerobic + aerobic treatment, and the SBR process and its improved versions. 1. Biological Contact Oxidation: This method involves loading packing material into a bioreactor. Microorganisms adhere to the packing material, forming a
Wastewater treatment at a brewery is a complex system engineering project that requires a multi-stage combined process, taking into account the high concentration of organic matter and large fluctuations in water quality and quantity. The core objectives are to effectively degrade organic matter, achieve compliant discharge, and recover resources as
Sugar refining wastewater is a typical high-concentration organic wastewater, characterized by large production volume, high COD (Chemical Oxygen Demand) and BOD5 (Biochemical Oxygen Demand) concentrations, good biodegradability, and deep color. Its treatment process typically employs a multi-stage combination to achieve efficient and stable purification. The mainstream process flow can be
