- High concentrations of Total Suspended Solids (TSS) in the aeration tank of the Secondary Water Treatment Plant (SWTP) were found to be related to the increased levels of nitrate and nitrite-N because of the nitrification and denitrification processes under the reduced oxygen conditions at mesophilic temperature. This issue was triggered in the aeration tank due to the transfer of residual ammoniacal-N from the Extended Granular Sludge Bed (EGSB) reactor through the effluent water. Under the low oxygen nitrification conditions, more oxygen supply facilitated nitrification, thus converting nitrite into nitrate by Nitrobacter. Almost 90 % reduction in TSS was found in the disposal water @ 36-37 ᵒC in the field conditions. However, in the case of high NO 3 -N, low levels of Dissolved Oxygen (DO) are recommended to enhance denitrification in the presence of Nitrosomonas in such a manner that NO 2 -N can squeeze O 2 from NO 3 -N. Similarly, in the case of high NO 2 -N, increased oxygen supply helped to reduce TSS. These strategies reduced TSS-laden N 2 liberation towards the surface of clarifiers. Total Suspended Solids (TSS) in the aeration tank were reduced to almost 90% compared to the initial solids in the aeration tank of the SWTP due to the nitrogen removal. Increased levels of DO (82 %) help to resolve the NO 2 -N accumulation issue in the aeration tank. Sludge volume in the aeration tank was reduced by 62% compared to the initial volume. Similarly, a 50% reduction in SVI30 was observed after 40 days of samples under field conditions, thus showing the removal of nitrogen from the system, which reduced the floatation of TSS.
- 研究发现，二级水处理厂（SWTP）曝气池中总悬浮固体（TSS）的高浓度与硝酸盐和亚硝酸盐-N 含量的增加有关，因为硝化和反硝化过程是在嗜中温的减氧条件下进行的。这一问题是由于曝气池中的残余氨氮通过出水从扩展颗粒污泥床（EGSB）反应器中转移出来而引发的。在低氧硝化条件下，更多的氧气供应有利于硝化，从而使硝化细菌将亚硝酸盐转化为硝酸盐。在 36-37 ᵒC的现场条件下，污水中的总悬浮物几乎减少了 90%。不过，在 NO 3 -N 较高的情况下，建议使用低浓度的溶解氧（DO）来加强亚硝单胞菌的反硝化作用，这样 NO 2 -N 就能从 NO 3 -N 中挤出 O 2。同样，在 NO 2 -N 较高的情况下，增加氧气供应有助于降低总悬浮固体。这些策略减少了含 TSS 的 N 2 向澄清池表面的释放。由于脱氮，曝气池中的总悬浮固体（TSS）比污水处理厂曝气池中最初的固体含量减少了近 90%。溶解氧水平的提高（82%）有助于解决曝气池中 NO 2 -N 的积累问题。曝气池中的污泥量与初始量相比减少了 62%。同样，在现场条件下取样 40 天后，观察到 SVI30 减少了 50%，这表明系统中的氮被去除，从而减少了 TSS 的上浮。

- Mangroves are essential ecosystems for the environment and are home to a particular biological diversity. They face many constraints, in particular, that of the invasion of exotic species such as Nypa fruticans. The research aim consisted of the characterization of Nipa palm traits in the Wouri estuary. The study was carried out in five points located in the main and secondary streams of the Wouri River. Floristic statements were inside twenty-five plots of 10 m x 10 m, and structural parameters such as the number of individuals, and DBH, with equidistance of 20m, were installed in five sites. The results showed that Nipa palm has an occurrence of 60 % in the studied sites. The higher density was obtained inAkwa-nord with 1309 individuals.ha -1 . The number of leaves significantly differed between the sampling points (K= 6.91; p= 0.03); Youpwe was the site with the higher number. Stalk width also differed significantly between the sites, from 25.2 cm in Essengue to 47.3 cm in Youpwe. Factor analysis revealed more matures and adults in Youpwe, juvenile plants in Essengue, and seedlings in Akwa-nord. This work showed that Youpwe would represent the oldest site and would have been the focus of the propagation of Nypa fruticans in the Wouri estuary.
