| Abstract | Seasonal effects of pre-aeration on microbial nitrogen performance in constructed wetlands (CWs) involved with anaerobic ammonium oxidation (anammox) process were investigated in this study. Slow natural re-aeration rate was the inhibiting factor for total nitrogen removal in CW without pre-aeration, and partial nitrification was the main way for nitrite generation. Besides partial nitrification, pre-aeration provided nitrite generation in CWs with an alternative way: nitrate reduction. Advantage of pre-aeration of influent was much different under various temperature ranges. Mean temperature of 15 °C seemed to be the turning point. With a mean temperature of or higher than 15 °C, nitrate in the influent effectively improved nitrogen removal in CWs. With a mean temperature lower than 15 °C, the nitrate reduction process in CWs was greatly inhibited. The benefit of pre-aeration was weak under this temperature range. Seasonal aeration pattern for the pre-treatment of HSSF CWs might be a more energy-saving alternative in in-suit domestic sewage treatment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
