Draft beer plant wastewater treatment method and treatment device

Abstract

The invention provides a draft beer plant wastewater treatment device which comprises a decontamination grid, a water collecting tank, a regulating and sedimentation tank, a retention-type anaerobic reactor, a liquid seal tank, a biogas storage box, a vertical flow sedimentation tank, an aerobic reaction tank, a blast blower, a biological absorption case, a sludge collecting well, a concentration tank, a sludge storage tank and a dehydration room. The draft beer plant wastewater treatment device can effectively lower the COD (chemical oxygen demand) value, BOD (biochemical oxygen demand) value and TN (total nitrogen) value of the draft beer plant wastewater. Besides, the concentration tank and dehydration room of the wastewater treatment device can collect the sediment and greatly lower the water content of the sediment, so that the sediment can be directly recovered. In addition, the invention also provides a draft beer plant wastewater treatment method.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a draft brewery waste water treatment method and treatment device. Background technique [0002] Draft beer (fresh beer) refers to beer that has been filtered through diatomaceous earth without sterilization. It tastes delicious. The yeast contained in draft beer can promote gastric secretion, increase appetite, and strengthen digestion. Draft beer is generally sold in bulk. No bubbles, slightly bitter taste, fresh at room temperature for a day or two. [0003] Draft beer undergoes a strict filtration process to remove impurities and become pure draft beer (pure fresh beer). Such beer will not deteriorate after several months of storage. The fresh yeast in draft beer can stimulate the secretion of gastric juice, increase appetite, promote digestion and absorption, and is very helpful for thin people to increase their physique and weight. Cooked beer is beer that has been pa...

Problems solved by technology

[0007] The treatment method disclosed in the above-mentioned patent does not disclose a technical solution for further processing the bottom sludge obtained after treatment. However, the bottom sludge obtained from draft beer factory wastewater contains relatively rich nutrients, which can promote the growth of crops well. role, but

If it is directly discharged into the river without treatment, it will not only cause a great waste of resources, but also the sediment is rich in organic matter, which will also lead to eutrophication of the water body
