四川某白酒厂废水处理工程设计

以四川某白酒厂生活污水及生产废水为对象,采用分质处理的工程措施,对生活污水（规模：400 m3/d）采用格栅调节池＋多功能污水处理装置＋ DE滤池的处理工艺,对生产废水（规模：2 000 m3/d）采用格栅提升泵房＋调节池（酸碱中和）＋溶气气浮＋上流式厌氧污泥床反应器＋厌氧内循环反应器＋A/A/O＋ MBR膜处理器＋（预留化学除磷）＋纳滤膜处理器的组合工艺进行处理.同时,对主要臭气产生构筑物采取加盖除臭（生物滤床除臭）的方式对臭气进行处理.处理后的生活污水达到《城镇污水处理厂污染物排放标准》（GB18918-2002）中一级A标准,生产废水达到《发酵酒精和白酒工业水污染物排放标准》（GB27631-2011）,以极大地削减污染物排放量,促进企业的可持续发展.

Engineering Design for Treatment of Wastewater from a Liquor Factory in Sichuan

The engineering measures were used by separating treatment to the domestic sewage and production wastewater from a liquor factory in Sichuan. On the one hand, the domestic sewage（ scale ：400 m3/d） was disposed by the combined process of water regulating tank, multifunc- tional sewage treatment device and DE filter. On the other hand, the production wastewater （scale： 2 000 m3/d） was disposed by the combined process of the pumping station, the water regulating tank （acid-base neutralization）, the dissolved air flotation, the upflow anaerobic sludge blan- ket reactor, the internal circulation anaerobic reactor, anaerobic-anoxic-oxic （A/A/O）, MBR membrane biological processor, the chemical phos- phorus removal and nanofiltration membrane processor. Moreover, the odor from production building structures was treated by the biofilter deodo- rization. After those measures, the domestic sewage accorded with Discharge Standard of Pollutants for Municipal Sastewater Treatment Plant （GB18918-2002）, and the production wastewater accorded with Discharge Standard of Water Pollutants for Fermentation Alcohol ahd Distilled Spirits Industry（ GB27631-2011 ）, which could reduce pollutant emissions and promote the company＇s sustainable development.
