A heterotrophic nitrifier, named strain HN, was isolated from the greenhouse soil. The cells of isolates were Gram positive, rod or coccus.
从大棚土壤中分离到一株异养型硝化细菌，命名为菌株HN ，分离菌株为革兰氏染色阳性，球状或杆状。

The experimental results showed that the nitrite accumulation obtained from selective inhibition of high concentration free ammonia to nitrifier was unstable.
试验结果表明：通过高浓度游离氨对硝化菌选择性抑制所获得的亚硝酸盐积累是不稳定的；

Ihese two issues can be solved simultaneously by bioaugment, that is sewage sludge water is used to enrichment the nitrifier, and then added to the sewage treatment system.
