摘要 本文通过小试,研究了利用淹没式生物膜法同时去除有机物和氮的工艺的可行性,通过在不同条件下的对比试验,确定了最佳操作条件和参数.发现淹没式生物膜法同时去除以BOD5和COD为代表的有机物及总NH3-N是十分有效的,剩余污泥量仅是利用具有相同处理能力的AS过程的剩余污泥量的1/20~1/10,因而节省了污泥处理及处置的投资、运行费用和管理费用.由于和AS过程相比没有污泥回流,使其操作运行方便. A bench-scale study was carried out to research the possibility and feasibility of the submerged biofilm process for the simultaneous removal of organic and nitrogen. The optimal operating conditions and parameters were determined by comparison study under different operating conditions. It has been found that the submerged biofilm process developed by the authors are very efficient in the simultaneous removal of organic substances in terms of COD and BOD5 and total ammonia nitrogen with quite high efficiencies and the surplus biomass was only 1/20 ~ 1/10 of surplus of activated sludge from a treatment plant using AS process of the same treatment capacity, which will save the capital and O/M costs significantly in sludge treatment and disposal. Besides the process is also easier to operate because there is no need to return the biomass as that in AS process.
