YEAST WASTEWATER TREATMENT METHOD AND FEED ADDITIVES AND FEED PRODUCTS OBTAINED FROM THE METHOD

摘要

A high concentration organic yeast wastewater treatment method and feed additives and feed products obtained from the method are provided. The method comprises the steps of evaporation, desalination and drying. In the method, the wastewater (1) is changed into fertilizer (8) and feed additives (11) to be used by the treatment, which not only improves the economic benefits of yeast wastewater, but also greatly reduces the cost of yeast wastewater treatment. In addition, it can also increase potassium in the fertilizer so as to obtain high-grade potash.
