果蔬食品废水处理工程实例
|
摘要
针对湖北某食品公司在食品加工过程中排放的污染物浓度高、可生化性好、悬浮物含量高的果蔬类废水,设计采用絮凝沉淀-UASB-A/O组合工艺进行处理,介绍该工艺的流程及设计参数,给出了处理效果。运行结果表明,该工艺技术路线选择合理,系统出水CODCr、 BOD5的质量浓度分别为60～80、 10～15 mg/L,出水稳定达到GB 8978—1996《污水综合排放标准》表4一级标准。
For the fruit and vegetable food wastewater discharged from processing unit of a food limited company in Hubei province has characteristics of high pollutant concentration, good biodegradability and high suspended solid content, flocculation sedimentation-UASB-A/O process was adopted for its treatment, the flow and design parameters of the process were introduced with the treatment effect pointed out at the same time. The operation results showed that the said process was a reasonable choice, the mass concentrations of CODCrand BOD5 in the effluent water reached 60-80 and 10-15 mg/L respectively, which stably met the requirement of table 4 of grade 1 in GB 8978—1996 Comprehensive Wastewater Discharge Standard.
