| 摘 要： | ［目的］提供一种快速、稳定、高效的猪场废水处理技术。［方法］通过厌氧/好氧（A/O）反应器处理猪场厌氧发酵液试验，研究了A/O处理猪场厌氧发酵液的启动过程。启动分2个阶段：第一阶段，厌氧（A）、好氧（O）段各自独立培养优势菌群；第二阶段，A、O联合启动，逐步提高进水负荷，继续对微生物培养与驯化，最终完成启动过程。［结果］当温度为32±2 ℃，回流混合液比和回流污泥比分别为2和1，O段曝气量为0.5 m3/h时，通过50 d的实际运行，COD、NH4＋ N的去除率分别达到89.87%和89.31%，表明反应器启动过程完成。［结论］可为猪场厌氧发酵液无害化技术提供一定的科学依据和借鉴。

| Abstract: | [Objective] The research aimed to provide a fast,stable and efficient piggery wastewater processing technology.[Method] The start-up process was studied through the experiment of piggery anaerobic fermentation slurry treated by Anoxic /Oxic(A/O) reactor.The process was divided into two stages: first stage,intensification of dominant microflora were conducted independently in A and O reaction tanks respectively;second stage,A and O reaction tanks were combined,with cultivation and domestication of microorgan... |
