Abstract

The invention discloses a beer waste water treatment process, comprising: water inlet, grating, solid-liquid separation, a water collection well, pH value regulation, anaerobic UASB, aerobic SBR and water outlet. The treatment process uses two-stage physicochemical separation by combining point adhesion of the beer waste water, guarantees stabilization operation of anaerobic UASB, simultaneously increases a pH value regulation technology, and is in favor of validity of anaerobic UASB technology treatment. The treatment process has advantages of simple process, low cost, obvious purifying effect, and easy utilization in production.

Description

technical field [0001] The invention relates to a wastewater purification process, in particular to a brewery wastewater treatment process. Background technique [0002] Beer is a nutrient-rich drink wine made from barley and water as the main raw materials, rice or grains as auxiliary materials, saccharified and fermented. The industrial wastewater produced by beer production mainly contains organic matter such as sugars and alcohols. The concentration of organic matter is high. Although it is non-toxic, it is easy to be corrupted. It requires a large amount of dissolved oxygen to be discharged into the water body, causing serious harm to the water body environment. At present, most of the treatment methods for beer wastewater are contact oxidation, but this method takes a long time to process, occupies a large area, and has relatively high operating costs. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the defici...
