不同碳源对Delftia tsuruhatensis HT01脱氮性能的影响

以一株异养氨氧化菌Delftia tsuruhatensis HT01为研究对象，比较了以十二烷基硫酸钠（SDS）、甘蔗糖蜜、丁二酸钠、乙酸钠、蔗糖、葡萄糖、果糖或柠檬酸钠等为唯一碳源时的生长情况及对TOC、NH₄⁺-N、TN的去除率，并通过两轮中试测试了该菌对皮革污水的处理效果.结果表明：HT01在异养条件下能够生成NO₂^--N，并可以在利用SDS （去除率为34%）的同时去除NH₄⁺-N和TN （去除率分别为74%和14%）；丁二酸钠和乙酸钠分别有利于实现最快的生长速度和最高的TOC去除率（71%），而果糖则有利于实现最高的NH₄⁺-N和TN去除率（分别为98%和29%）.HT01能够在皮革污水中生长，第2轮中试对COD，NH₄⁺-N和TN的去除率分别达到38%，49%和22%.

The influence of different carbon sources on the nitrogen removal characters of a Delftia tsuruhatensis HT01

The growth and the removal efficiency of TOC, NH₄⁺-N and TN of a heterotrophic ammonia oxidizer Delftia tsuruhatensis HT01 were studied when SDS, cane molasses, sodium succinate, sodium acetate, sucrose, glucose, fructose or sodium citrate was used as sole carbon source. Furthermore, two rounds of the pilot-scale test were performed using leather sewage. The results indicated that NO₂^--N was produced in heterotrophic condition by HT01 and NH₄⁺-N, TN and SDS were removed simultaneously at the removal efficiency of 74%, 14% and 34%, respectively. Moreover, the highest growth rate and the highest removal efficiency of TOC (71%) were observed when sodium succinate and sodium was used as sole carbon source, respectively. While the highest removal efficiency of NH₄⁺-N (98%) and TN (29%) were observed when fructose was used as sole carbon source. The growth of HT01 was observed in leather sewage, and the removal efficiency of COD, NH₄⁺-N and TN was 38%, 49% and 22%, respectively, in the second round of pilot-scale test.
