硝化细菌富集培养及处理富营养化水体应用研究

Reserch on Enrichmental Cultivation of Nitrobacteria and Dealing with Eutrophic Water Body

通过对沈阳市北部污水处理厂曝气池的活性污泥进行培养,使污泥中异养细菌数量减少,硝化细菌数量增加,成为优势菌,并用此污泥处理富营养化水体,结果氨氮大幅度降低。

By cultivating the activated sludge which in the aerator of Shen Yang Northern Sewage Treatment Plant, the number of the heterotrophic bacteria in the sludge decrease while that of the nitrobacteria which become the predominant bacteria increase. This sludge is used to dealing with the eutrophic water body. The result is that ammonia-nitrogen decreases dramatically.
