厌氧-好氧组合工艺处理牛奶厂废水工程实例

A Case Study of Anaerobic and Aerobic Combination Technique for Waste Water Treatment at a Milk Factory

针对昆明某牛奶厂废水处理的工程实例,选用"厌氧+好氧"(ABR)的处理工艺,具有能耗低、运行稳定、运行费用低等优点。同时无PAC、PFS等化学混凝药剂投加,不会产生二次污染问题。经处理后出水水质优良,其中COD、BOD、SS等出水指标均优于国家标准的要求。

In an experiment for waste water treatment at a milk factory, anaerobic and aerobic were com-bined technically, by which, it worked well, meanwhile energy consumption and the cost were re-duced. Besides, the secondary pollution is avoided in this way without adding chemical coagulation rea-gent （PAC、 PFS） and the processed effluent meets the national standard and is even superior for its in-dicators as COD, BOD and SS.
