Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with specific embodiments, but not limited to specific examples.

[0011] The concrete steps of the biological treatment method of beer wastewater are:

[0012] 1. Add acidifying enzyme to the beer wastewater to be treated for pretreatment, and measure the pH value of the solution. When the pH value reaches 5.5, the pretreatment process is over.

[0013] 2. Let the pretreated beer wastewater pass through a drum filter to filter organic matter, so as to filter out macromolecular organic matter in the wastewater.

[0014] 3. Add hydrolytic acidification bacteria to the filtered wastewater and react in the biological contact oxidation tank for more than 30 minutes. In this process, it is necessary to continuously measure the temperature in the oxidation pool, and keep the temperature at 25°C-29°C to achieve the best activity of the hydrolytic acidification enzyme reaction. At the same time, it ...

Abstract

The invention provides a biological treatment method of beer wastewater, and the method utilizes the activity of biological enzyme and metabolism of hydrolysis acidate bacteria to treat harmful substances in the beer wastewater. The method has the advantages of simple operation, short treatment time, having no secondary pollutant in the treatment process, safety and environmental protection.

Description

1. Technical field: [0001] The invention relates to a method for treating wastewater, in particular to a method for treating brewery wastewater. 2. Background technology: [0002] Beer industry wastewater 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 needs to consume a large amount of dissolved oxygen when it is discharged into the water body, causing serious pollution to the water body environment. At present, the methods for treating beer wastewater mainly include acidification-SBR method, aerobic contact oxidation process, and new contact oxidation method. Although these methods can treat beer wastewater to a certain extent, the process is complex, the reaction time is long, and due to the use of chemical agents, secondary pollution problems are likely to occur. 3. Contents of the invention: [0003] The purpose of the present invention is to overcome abo...
