白酒废水深度脱氮除磷的工程实践

Engineering Practice of Deep Nitrogen and Phosphorus Removal from Liquor Wastewater

摘要: 为了扩大处理规模及提高出水水质，对湖北某白酒公司产生的白酒废水进行工程设计。采用预处理-UASB-两级A/O-芬顿工艺对白酒废水进行深度处理，并介绍了主要构筑物及相关设计参数。实践结果表明：色度 < 10，COD < 30 mg/L，SS < 25 mg/L，氨氮 < 4 mg/L，总氮氨氮 < 19 mg/L，总磷氨氮 < 0.9 mg/L，出水水质优于《发酵酒精和白酒工业水污染物排放标准》(GB27631-2011)直接外排标准，满足设计要求。

Abstract: In order to expand the scale of treatment and improve the quality of effluent water, the engineering design of liquor wastewater produced by a liquor company in Hubei was carried out. The pre-treatment-UASB-two-stage A/O-Fenton process was used to treat the liquor wastewater in depth, and the main structures and related design parameters were introduced. Practice results show: chromaticity < 10, COD < 30 mg/L, SS < 25 mg/L, ammonia nitrogen < 4 mg/L, total nitrogen am-monia nitrogen < 19 mg/L, total phosphorus ammonia nitrogen < 0.9 mg/L. It is superior to the direct efflux standard of “Emission Standard for Water Pollutants of Fermented Alcohol and Liquor Industry” (GB27631-2011) and meets the design requirements.
