摘 要：
大蒜是我国重要的农作物品种,大蒜制品深受人民群众喜爱,但大蒜加工时中会产生大量高浓度有机废水,且伴有强烈刺鼻气味,故须对其处理后方可达标排放.大蒜废水中含有较多难降解物质,在实际处理过程中往往面临较大困难,适当工艺流程的选取对其高效处理极为关键.基于工程实践对大蒜废水处理工艺进行了剖析,明确了"EGSB+UASB"厌氧联合处理工段可高效降解废水中的有机物,气浮及混凝工段可稳定去除废水中的悬浮物及总磷,处理后出水可稳定达到《污水综合排放标准》(GB8978-1996)三级标准.该工艺单位水处理成本为 29.37 元/t,较于集中处理前 40~60 元/t处理成本大幅降低,年运营费用可节约超 300 万元,可为同类工程实践提供工艺参考及借鉴.

摘 要：
Garlic is a significant agricultural crop in our country, and its processed products are widely popular among the populace. However, substantial quantities of high-concentration organic wastewater, accompanied by a pungent odor, are generated during garlic processing, necessitating appropriate treatment to meet discharge standards. Garlic wastewater contains numerous recalcitrant substances, and it often presents challenges during the actual treatment process. The selection of an appropriate process flow is vital for the efficient treatment of this wastewater. This paper provides an in-depth analysis of the garlic wastewater treatment process based on engineering practice and identifies that the anaerobic joint treatment section, comprising the expanded granular sludge bed(EGSB) and the upflow anaerobic sludge blanket(UASB), can effectively degrade organic matter in the wastewater. The air flotation and coagulation section can stably remove suspended solids and total waste in the wastewater, including phosphorus. After treatment, the effluent can consistently meet the third-level standard of the Integrated Wastewater Discharge Standard GB8978-1996. The treatment cost of this process unit is 29.37 yuan/ton, significantly lower than the 40～60 yuan/ton treatment cost before centralized treatment. Moreover, the annual operating cost savings exceed 3 million yuan, providing valuable insights and references for similar engineering practices.
