A study on succession of phytoplankton in a municipal waste water treatment was conducted from a major drainage streamsystem receiving municipal wastes from densely populated urban municipality of Port Harcourt in Rivers State, Niger Deltaof Nigeria. The study area lies within 4º 88′′ - 4º 99′′ N and 5º 00′′ - 5º 14′′ E. The study was carried out to investigate thevariation of phytoplankton communities and their interactions with the physico-chemical characteristics of the waste waterbeing treated with sunlight. The phytoplankton population indicated six (6) major successional development patterns in therecruitment of species. This affected the distribution of phytoplankton descriptors such as species diversity -H’ (thatdecreased from 0.99 on the 1st day to 0.62 on the16th day), dominant index -DI (with minimum of 0.000085 on the 1st day tomaximum of 0.12 on the 11th day), community structure and biomass at various stages of the depuration and correlateddifferently with the physicochemical parameters. The results suggest that phytoplankton was mainly regulated by nutrientsand the massive Cyanobacterial bloom declined as the water quality improved which were well related to changes in algaediversity, dominance index, abundance and biomass. A model to compare actual and predicted values indicated somecoherence between several biological and physicochemical attributes. |
