摘　　要：采用内循环折流式生物反应器(ICBBR)和水生植物处理城市黑臭河水,考察反应器和生态系统的脱氮效果。结果表明,反应器的最佳运行条件是以梧桐叶作为黑臭河水外加碳源,河水中有机污染物(COD)与总氮(TN)之比保持在8~12,水温控制在20~25℃;三种植物中狐尾藻对氨氮(NH_(3)-N)、TN去除效果最佳,其次是苦草和黑藻,综合生态系统多样性和景观欣赏性,生态池采用狐尾藻、苦草和黑藻以3︰2︰1栽种。The internal circulating baffled bioreactor(ICBBR)and hydrophyte were studied for the treatment of malodorous black water.The results showed the optimum operating conditions of ICBBR were as follows:indus leaf as the carbon source,COD/TN ratio 8~12,operating temperature 20~25℃.Among three species myriophyllum spicatum exhibited the best purification effect for NH_(3)-N and TN removal,followed by vallisneria asiatica and hydrilla verticillata.Based on the diversity of ecosystem and the appreciation of landscape,The ratio of myriophyllum spicatum,vallisneria asiatica and hydrilla verticillata was fixed at 3︰2︰1 in ecological pool.
