Next, we will calculate the amount of wastewater discharged by the beer industry in China by producing one ton of beer and producing 20 tons of wastewater. However, the comprehensive utilization and wastewater treatment of most breweries in our country are not very ideal, which seriously pollutes the ecological environment. Cod, bod and ss are the main items that often exceed standards in wastewater discharged by breweries.
According to the main source of beer wastewater, it can be divided into two categories: cooling water and washing water. Therefore, the waste water is large, non-toxic and harmless, contains a lot of organic matter, is a high concentration of organic wastewater, in the treatment of such wastewater, it is recommended to use cationic polyacrylamide flocculant.
The invention discloses a polyacrylamide flocculant wastewater treatment method for organic wastewater in the production process of beer and other beverages and food. Sulfuric acid has a very obvious flocculation and precipitation effect, how many polyacrylamide flocculants are needed to treat 1 ton of wastewater? This is one of the common concerns of users.
Usually when adding 1 ton of sewage, the polyacrylamide flocculant content is only a few grams, and the change is great. In the process of sewage treatment, it is often difficult to determine its content due to the complexity of its influent water quality. However, it must be dissolved with a polyacrylamide flocculant, according to the dissolution rate provided by the manufacturer (1-3%).
For the specific amount of sewage, a small test should be carried out before adding materials to determine the specific dosage. In general, the amount of wastewater treated with polyacrylamide flocculant, the dosage of polyacrylamide flocculation consumed in a ton of raw water is about (1-10 grams), of course, this value is not recommended for your reference, the specific value still needs to be tailored by the demand side.
