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
Commonly used aerobic biological treatment methods include activated sludge process, deep well aeration process, adsorption biodegradation process (AB process), contact oxidation process, sequencing batch reactor (SBR) process, and circulating activated sludge process (CASS process). (1) Biological Contact Oxidation Process: This technology combines the advantages of activated sludge and biofilm processes,
Treatment methods include: activated sludge process, bio-enhanced technology, supercritical water oxidation, etc. These methods aim to reduce wastewater generation at its source, eventually reaching zero, which is known as coking wastewater reduction technology. Specifically: 1. Crude benzene separation water: Treatment method: negative pressure distillation. This lowers the boiling point of
MBR, also known as membrane bioreactor, is a modern wastewater treatment technology that combines activated sludge process with membrane separation technology. Membrane bioreactor has replaced the secondary sedimentation tank in traditional processes. It can efficiently perform solid-liquid separation, obtain stable recycled water that can be directly used, and maintain a
