屠宰及肉类加工行业废水深度处理技术工艺研究

Research on the Technique of Wastewater Advanced Treatment in Slaughtering and Meat Processing Industry

屠宰及肉类加工污水中COD、氨氮等浓度高,因此对污水处理技术工艺要求较高。研究废水深度处理技术工艺,通过试验及实例分析表明:二级生化处理后段加生物曝气池(BAF)深度处理工艺可有效去除水中污染物质,达到国家污水综合排放标准。

In the wastewater of slaughtering and meat processing, the density of COD, ammonia and nitrogen is pretty high. In this case, the request to the technique of wastewater treatment is relatively high. The article presents the research on the technique of wastewater advanced treatment, listed the experiments and practical examples for analyzing, the result shows： last part of secondary biochemical treatment with BAF advanced treatment technique can remove the pollutant in the water, after it, the water can reach national standard of wastewater comprehensive discharge.
