Research on the Resource Utilization of Beer Wastewater
In order to explore the impact and effectiveness of beer wastewater directly entering municipal sewage treatment plants without pre-treatment,and achieve comprehensive utilization of carbon waste and turning waste into treasure,the arti-cle takes Qingdao Beer(Suizhou)Co.,Ltd.as an example,analyzes the comprehensive wastewater generated by the enterprise and the operating data of the Suizhou sewage treatment plant in the previous year,and predicts the impact of beer wastewater resource utilization on the sewage treatment plant.After the implementation of the project,data from one year of operation was analyzed,summarized,and evaluated.The results showed that the predicted values were basically consistent with the actu-al results.After the utilization of beer wastewater as a resource,the COD concentration in the wastewater treatment plant in-creased by 18.93％.The carbon environment during wastewater operation was improved,and the operation was more stable.The TN concentration in the effluent decreased from 9.50～20.77 mg/L to 8.78～12.7 mg/L,and 90％of the operationtime was less than 10.0 mg/L,with the removal rate increased by 16.78 percentage points.CO2 emissions decreased by 2 816 tons/year,whihe saving 1.111 2 million yuan/year in costs.
