摘要
采用SBR工艺用屠宰废水对生活污水处理厂曝气池中的活性污泥进行驯化,对进出水的COD、氨氮进行监测,测量污泥特性。通过分离培养污泥微生物,对不同时期污泥菌群和菌落计数分析,结果表明:在驯化初期部分菌群被淘汰,驯化中、后期部分菌群适应废水,数量增加;驯化结束时,污泥中微生物组成基本稳定,细菌为主要菌群,COD和氨氮的去除率分别为89%和98%,含量均达到了一级排放标准。
The activated sludge from wastewater treatment is domesticated by the SBR process with slaughter house wastewater, the COD and ammonia-nitrogen contents are determined, by which the sludge characteristics are measured. The sludge bacteria groups and colonies in different periods are counted and analyzed by separating and culturing sludge microor- ganisms. The result of the experiment shows that a few of the microbe groups are eliminated in the early days, and the quantity of part of the microbe groups increase in the mid late period because of they gradually adapt to the wastewater. At the end of domestication, the microorganisms of the activated sludge keep stable and most of them are bacterium, the removal rates of COD and ammonia-nitrogen are 89% and 98% respectively. Both the contents meet the first grade standard of China.
