摘要:

啤酒废水有机物浓度较高,直接排放会引起水体富营养化,而单独处理不仅增加运营成本,还会产生大量温室气体,同时浪费了废水中可利用的有机碳源。将啤酒废水作为补充碳源与市政污水协同处理,可同时实现环境效益和经济效益。以某啤酒生产企业预处理后的废水为例,将其直接纳管排放到临近的污水处理厂,采用基线对比分析法,从处理效果、经济效益、环境效益等3个层面评估啤酒废水资源化利用的可行性。结果表明,啤酒废水纳管排放后,污水处理厂的进水COD提升了47.47%,其他进水水质参数波动相对较小,出水COD、氨氮、总磷、总氮与引入啤酒废水前相比变化不大,符合《城镇污水处理厂污染物排放标准》(GB 18918—2002)中一级A标准。此外,啤酒废水与市政污水协同处理可使啤酒生产企业和市政污水处理厂每年共节约费用154.6万元,碳排放量减少284.6 t,具有良好的环境效益和经济效益。

Abstract:

Brewery wastewater has a high concentrations of organic matter. Direct discharge can lead to water eutrophication, while the separate treatment not only increases operational costs but also results in substantial greenhouse gas emissions, simultaneously wasting the recoverable organic carbon sources contained in the wastewater. Using brewery wastewater as a supplementary carbon source for co-treatment with municipal sewage can achieve both environmental and economic benefits. Taking pretreated wastewater generated by a certain brewery as an example, it was discharged directly into an adjacent wastewater treatment plant via the sewer network. This study adopted the method of baseline comparison analysis, conducted analysis from three aspects including treatment effect, economic benefit and environmental benefit, and measured the feasibility of resource utilization of brewery wastewater. The results indicated that after the introduction of brewery wastewater, the influent COD of the wastewater treatment plant increased by 47.47%, while other influent water quality parameters exhibited only minor fluctuations. The effluent COD, ammonia nitrogen, total phosphorus, and total nitrogen all showed little change compared to the period before the introducing of brewery wastewater, complying with the Level 1 A standards in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918—2002). Moreover, the synergistic treatment of brewery wastewater and municipal wastewater enabled brewery and municipal wastewater treatment plant to save a total of 1.546 million yuan and reduce carbon emissions by 284.6 t annually, demonstrating significant environmental and economic benefits.
