1. Wastewater generated during the wine production process mainly originates from multiple production stages. Rice washing water and soaking water from the brewing stage contain a large amount of organic matter; waste liquid from the fermentation stage is rich in sugars, proteins, and yeast residue; wastewater from the distillation stage
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
Phosphorus removal methods for brewing wastewater are generally divided into biological and chemical methods: 1. Biological methods: Biological phosphorus removal refers to the nitrification and decomposition of organic phosphorus or metaphosphate by aerobic bacteria under certain conditions. Some phosphorus is absorbed by the microorganisms, becoming microbial sludge; the remaining phosphorus
