摘要
试验以甲醇配水作为污水，研究利用外加硝酸盐的反硝化技术去除难以复氧的低溶解氧水中的有机物的可行性。结果表明：达到最佳去除效果时，外加硝酸盐与有机污染物的N／C为1．4，停留时间为16h时有机物去除率可达86％，15℃以上时去除率受温度影响不大。
The bioreclamation of some kinds of wastewater was often limited because of the amount of available electron acceptors. So the use of alternative electron acceptors was necessary. The utilization of nitrate as the electron acceptors to degrade the organic substance under anoxic condition was a kind of new technology. It had been shown from the experiment results, the best ratio of adding quantity of nitrate and organic substance (N/C) was 1. 4, the proper retention period was 16hrs, the corresponding removal efficiency of organic substances was up to 86 %. In the meantime, the efficiency remained stable when the temperature of wastewater was higher than 15℃.
