摘要：

在常温条件下采用自制厌氧反应器处理乳品废水，研究了反应器的启动特性、颗粒污泥的形成、反应器高效稳定运行条件。结果表明，运行第30天完成反应器启动；启动完成的同时培养出性能良好的颗粒污泥；厌氧反应器高效稳定运行临界负荷为14 kgCOD/（m³·d）（水力停留时间为5.1 h），临界泥量为26.7 g/L（约为反应器体积的1/2）。

Abstract:

A self-made anaerobic reactor was used to treat dairy wastewater under normal temperature conditions. The start-up characteristics of the reactor, the formation of granular sludge, and the efficient and stable operation conditions of the reactor were studied. The results showed that the reactor start-up was completed on the 30th day of operation.The granular sludge with good performance was cultivated at the same time as the start-up was completed. The critical load for the efficient and stable operation of the anaerobic reactor was 14 kgCOD/(m³·d) (hydraulic retention time 5.1 h), the critical mud volume is 26.7 g/L(about 1/2 of the reactor volume).

Key words: dairy wastewater, anaerobic reactor, granular sludge, mud volume, load
