The choice of process flow for dairy wastewater treatment depends on the characteristics of the wastewater and the effluent discharge requirements. The treatment process is primarily biological, and based on the main unit responsible for pollutant removal load, it can be divided into aerobic treatment systems and “anaerobic + aerobic”
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
The main raw materials and resources for dairy production in dairy factories are fresh milk, sugar, peanuts, walnuts, electricity, water, and coal. During the dairy production process, wastewater such as tank washing water and bottle washing water is generated. This wastewater, along with floor washing water, toilet flushing water, and
