Abstract

The need for treatment of municipal wastewater prior to its disposal is important. One method used for treating wastewater is that of constructed wetland system (CW). The use of CW has attracted interest in developing nations due to its operation pollutants from a sew age that feeds into a major river system in Nigeria. The CW, which employs hydrophytes to degrade the wastewater from a facility of nearly ten thousand people, is compromised of six tanks made of cement blocks. Samples were collected from the entry and exit points of each cell of the CW and analyzed for dissolved oxygen, conductivity, pH and temperature. The pH remained constant (6.8-6.9) at ambien temperature of 27 degrees Celsius. Conductivity ranged from 700 to 840 ppm. The dissolved oxygen (DO) ranged from 0.9mg/l at the entrance to 0.1 mg/l at the final exit point. Analysis of the data suggests that the CW is not efficient and steps need to be taken to improve its performance. Some improvements can include aeration and increase in resident times of the wastewater in each cell of the CW.
