以常州市厨余垃圾为研究对象，采用UASB反应器，就一次性进料餐厨垃圾厌氧处理条件下运行及工艺参数（如pH、碱度、氨氮等）进行实验研究。结果表明：在厨余垃圾厌氧消化过程中氨氮是不断增加累计的， pH维持在7.6左右； COD从开始的20000~140000 mg/L到最终UBF出水10000~12000 mg/L； VFA随着时间的增加逐渐降低；总氮先升高后降低；产气量随着时间较稳定增加。

Taking food waste from Changzhou as the research object, the experimental research on the operation and process parameters (including pH, alkalinity, ammonia nitrogen, and so on) of food waste anaerobic treatment were carried out under the conditions of one-time feeding by using UASB reactors. The results showed that ammonia nitrogen cumulated continuously in the process of food waste anaerobic digestion, and pH was maintained about 7. 6. At first the value of COD ranged from 20 000 mg/L to 140 000 mg/L to the final UBF water 10 000 mg/L to 12 000 mg/L. VFA became less with time increase. Total nitrogen first increased and then decreased. Biogas production increased stably over time.
