本文介绍了餐厨垃圾厌氧发酵工艺以及该发酵工艺现场运营的难点，结合老龄化填埋场渗滤液可生化性较低，需要外加商品碳源满足生化处理所需营养，阐述了厌氧发酵罐附加酸化改造的重要性。餐厨垃圾处置厂联合渗滤液处理厂启动酸化试验，结果表明：通过定向产酸后的酸化液作为碳源进行水质调配，符合污水厂生化出水标准要求COD < 800 mg/L；NH3-N < 50 mg/L；TN < 100 mg/L。
This paper introduces the anaerobic fermentation process of food waste and the difficulties in the operation of the fermentation process. Combined with the aging of landfill leachate (low biodegra-dability) in the park, and the need for additional commercial carbon source to meet the nutritional requirements of biochemical treatment, the importance of additional acidification transformation of anaerobic fermentation tank is elaborated from the above two aspects. The result shows that the acidification liquid after directional acid production is used as carbon source for water quality al-location, which meets the requirements of biochemical effluent standard: COD < 800 mg/L; NH3-N < 50 mg/L; TN < 100 mg/L.
