摘要
采用柱式光合反应器对藻类去除煤气化废水的氨氮及总氮开展了探索性实验研究。实验结果表明:优化条件下,四尾栅藻、斜生栅藻、混合藻(黄丝藻和席藻)都在3 d内完全去除氨氮,同时总氮去除率都在第5天达到最大,分别是四尾栅藻86.02%,斜生栅藻83.33%,混合藻71.81%。说明选用合适的藻类去除煤气化废水的氨氮及总氮可行,同时相比生物硝化/反硝化脱氮工艺该方法具有一定的新颖性。
The column photo-bioreactor has been used for algae removing ammonia nitrogen and total nitrogen with algae from coal-gasification wastewater. Experimental results show that under the optimized conditions, Scenedesmus quadricanda,Scnedesmus obliquus and compound algae （Tribonerna and Phorrnidium） can make statistically thor- ough removal of the ammonia nitrogen from coal-gasification wastewater within 3 d, and the removing efficiency of total nitrogen from coal-gasification wastewater has reached the maximum on the 5th day,which is 86.02% with Scenedesrnus quadricanda, 83.33% with Scnedesmus obliquus, and 71.81% with the compound algae. The results re- veal that it is feasible to remove ammonia nitrogen and total nitrogen from coal gasification wastewater by using ap- propriate algae. Besides, compared with the biological nitrification/denitrification denitrogenation process, the pro- cess is also significantly original.
